With fb_var_screeninfo, things such as - depth and the resolution may be defined. - - - - The next structure is fb_fix_screeninfo. This defines the - properties of a card that are created when a mode is set and can't - be changed otherwise. A good example of this is the start of the - frame buffer memory. This "locks" the address of the frame buffer - memory, so that it cannot be changed or moved. - - - - The last structure is fb_monospecs. In the old API, there was - little importance for fb_monospecs. This allowed for forbidden things - such as setting a mode of 800x600 on a fix frequency monitor. With - the new API, fb_monospecs prevents such things, and if used - correctly, can prevent a monitor from being cooked. fb_monospecs - will not be useful until kernels 2.5.x. - - - Frame Buffer Memory -!Edrivers/video/fbdev/core/fbmem.c - - - Frame Buffer Colormap -!Edrivers/video/fbdev/core/fbcmap.c - - - Frame Buffer Video Mode Database -!Idrivers/video/fbdev/core/modedb.c -!Edrivers/video/fbdev/core/modedb.c - - Frame Buffer Macintosh Video Mode Database -!Edrivers/video/fbdev/macmodes.c - - Frame Buffer Fonts - - Refer to the file lib/fonts/fonts.c for more information. - - - - - - - Input Subsystem - Input core -!Iinclude/linux/input.h -!Edrivers/input/input.c -!Edrivers/input/ff-core.c -!Edrivers/input/ff-memless.c - - Multitouch Library -!Iinclude/linux/input/mt.h -!Edrivers/input/input-mt.c - - Polled input devices -!Iinclude/linux/input-polldev.h -!Edrivers/input/input-polldev.c - - Matrix keyboards/keypads -!Iinclude/linux/input/matrix_keypad.h - - Sparse keymap support -!Iinclude/linux/input/sparse-keymap.h -!Edrivers/input/sparse-keymap.c - - - - - Serial Peripheral Interface (SPI) - - SPI is the "Serial Peripheral Interface", widely used with - embedded systems because it is a simple and efficient - interface: basically a multiplexed shift register. - Its three signal wires hold a clock (SCK, often in the range - of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and - a "Master In, Slave Out" (MISO) data line. - SPI is a full duplex protocol; for each bit shifted out the - MOSI line (one per clock) another is shifted in on the MISO line. - Those bits are assembled into words of various sizes on the - way to and from system memory. - An additional chipselect line is usually active-low (nCS); - four signals are normally used for each peripheral, plus - sometimes an interrupt. - - - The SPI bus facilities listed here provide a generalized - interface to declare SPI busses and devices, manage them - according to the standard Linux driver model, and perform - input/output operations. - At this time, only "master" side interfaces are supported, - where Linux talks to SPI peripherals and does not implement - such a peripheral itself. - (Interfaces to support implementing SPI slaves would - necessarily look different.) - - - The programming interface is structured around two kinds of driver, - and two kinds of device. - A "Controller Driver" abstracts the controller hardware, which may - be as simple as a set of GPIO pins or as complex as a pair of FIFOs - connected to dual DMA engines on the other side of the SPI shift - register (maximizing throughput).

More specifically, it +is a dynamic checker that detects and warns about some uses of uninitialized +memory. + +Userspace programmers might be familiar with Valgrind's memcheck. The main +difference between memcheck and kmemcheck is that memcheck works for userspace +programs only, and kmemcheck works for the kernel only. The implementations +are of course vastly different. Because of this, kmemcheck is not as accurate +as memcheck, but it turns out to be good enough in practice to discover real +programmer errors that the compiler is not able to find through static +analysis. + +Enabling kmemcheck on a kernel will probably slow it down to the extent that +the machine will not be usable for normal workloads such as e.g. an +interactive desktop. kmemcheck will also cause the kernel to use about twice +as much memory as normal. For this reason, kmemcheck is strictly a debugging +feature. + + +Downloading +----------- + +As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel. + + +Configuring and compiling +------------------------- + +kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of +configuration variables must have specific settings in order for the kmemcheck +menu to even appear in "menuconfig". These are: + +- ``CONFIG_CC_OPTIMIZE_FOR_SIZE=n`` + This option is located under "General setup" / "Optimize for size". + + Without this, gcc will use certain optimizations that usually lead to + false positive warnings from kmemcheck. An example of this is a 16-bit + field in a struct, where gcc may load 32 bits, then discard the upper + 16 bits. kmemcheck sees only the 32-bit load, and may trigger a + warning for the upper 16 bits (if they're uninitialized). + +- ``CONFIG_SLAB=y`` or ``CONFIG_SLUB=y`` + This option is located under "General setup" / "Choose SLAB + allocator". + +- ``CONFIG_FUNCTION_TRACER=n`` + This option is located under "Kernel hacking" / "Tracers" / "Kernel + Function Tracer" + + When function tracing is compiled in, gcc emits a call to another + function at the beginning of every function. This means that when the + page fault handler is called, the ftrace framework will be called + before kmemcheck has had a chance to handle the fault. If ftrace then + modifies memory that was tracked by kmemcheck, the result is an + endless recursive page fault. + +- ``CONFIG_DEBUG_PAGEALLOC=n`` + This option is located under "Kernel hacking" / "Memory Debugging" + / "Debug page memory allocations". + +In addition, I highly recommend turning on ``CONFIG_DEBUG_INFO=y``. This is also +located under "Kernel hacking". With this, you will be able to get line number +information from the kmemcheck warnings, which is extremely valuable in +debugging a problem. This option is not mandatory, however, because it slows +down the compilation process and produces a much bigger kernel image. + +Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory +Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows +a description of the kmemcheck configuration variables: + +- ``CONFIG_KMEMCHECK`` + This must be enabled in order to use kmemcheck at all... + +- ``CONFIG_KMEMCHECK_``[``DISABLED`` | ``ENABLED`` | ``ONESHOT``]``_BY_DEFAULT`` + This option controls the status of kmemcheck at boot-time. "Enabled" + will enable kmemcheck right from the start, "disabled" will boot the + kernel as normal (but with the kmemcheck code compiled in, so it can + be enabled at run-time after the kernel has booted), and "one-shot" is + a special mode which will turn kmemcheck off automatically after + detecting the first use of uninitialized memory. + + If you are using kmemcheck to actively debug a problem, then you + probably want to choose "enabled" here. + + The one-shot mode is mostly useful in automated test setups because it + can prevent floods of warnings and increase the chances of the machine + surviving in case something is really wrong. In other cases, the one- + shot mode could actually be counter-productive because it would turn + itself off at the very first error -- in the case of a false positive + too -- and this would come in the way of debugging the specific + problem you were interested in. + + If you would like to use your kernel as normal, but with a chance to + enable kmemcheck in case of some problem, it might be a good idea to + choose "disabled" here. When kmemcheck is disabled, most of the run- + time overhead is not incurred, and the kernel will be almost as fast + as normal. + +- ``CONFIG_KMEMCHECK_QUEUE_SIZE`` + Select the maximum number of error reports to store in an internal + (fixed-size) buffer. Since errors can occur virtually anywhere and in + any context, we need a temporary storage area which is guaranteed not + to generate any other page faults when accessed. The queue will be + emptied as soon as a tasklet may be scheduled. If the queue is full, + new error reports will be lost. + + The default value of 64 is probably fine. If some code produces more + than 64 errors within an irqs-off section, then the code is likely to + produce many, many more, too, and these additional reports seldom give + any more information (the first report is usually the most valuable + anyway). + + This number might have to be adjusted if you are not using serial + console or similar to capture the kernel log. If you are using the + "dmesg" command to save the log, then getting a lot of kmemcheck + warnings might overflow the kernel log itself, and the earlier reports + will get lost in that way instead. Try setting this to 10 or so on + such a setup. + +- ``CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT`` + Select the number of shadow bytes to save along with each entry of the + error-report queue. These bytes indicate what parts of an allocation + are initialized, uninitialized, etc. and will be displayed when an + error is detected to help the debugging of a particular problem. + + The number entered here is actually the logarithm of the number of + bytes that will be saved. So if you pick for example 5 here, kmemcheck + will save 2^5 = 32 bytes. + + The default value should be fine for debugging most problems. It also + fits nicely within 80 columns. + +- ``CONFIG_KMEMCHECK_PARTIAL_OK`` + This option (when enabled) works around certain GCC optimizations that + produce 32-bit reads from 16-bit variables where the upper 16 bits are + thrown away afterwards. + + The default value (enabled) is recommended. This may of course hide + some real errors, but disabling it would probably produce a lot of + false positives. + +- ``CONFIG_KMEMCHECK_BITOPS_OK`` + This option silences warnings that would be generated for bit-field + accesses where not all the bits are initialized at the same time. This + may also hide some real bugs. + + This option is probably obsolete, or it should be replaced with + the kmemcheck-/bitfield-annotations for the code in question. The + default value is therefore fine. + +Now compile the kernel as usual. + + +How to use +---------- + +Booting +~~~~~~~ + +First some information about the command-line options. There is only one +option specific to kmemcheck, and this is called "kmemcheck". It can be used +to override the default mode as chosen by the ``CONFIG_KMEMCHECK_*_BY_DEFAULT`` +option. Its possible settings are: + +- ``kmemcheck=0`` (disabled) +- ``kmemcheck=1`` (enabled) +- ``kmemcheck=2`` (one-shot mode) + +If SLUB debugging has been enabled in the kernel, it may take precedence over +kmemcheck in such a way that the slab caches which are under SLUB debugging +will not be tracked by kmemcheck. In order to ensure that this doesn't happen +(even though it shouldn't by default), use SLUB's boot option ``slub_debug``, +like this: ``slub_debug=-`` + +In fact, this option may also be used for fine-grained control over SLUB vs. +kmemcheck. For example, if the command line includes +``kmemcheck=1 slub_debug=,dentry``, then SLUB debugging will be used only +for the "dentry" slab cache, and with kmemcheck tracking all the other +caches. This is advanced usage, however, and is not generally recommended. + + +Run-time enable/disable +~~~~~~~~~~~~~~~~~~~~~~~ + +When the kernel has booted, it is possible to enable or disable kmemcheck at +run-time. WARNING: This feature is still experimental and may cause false +positive warnings to appear. Therefore, try not to use this. If you find that +it doesn't work properly (e.g. you see an unreasonable amount of warnings), I +will be happy to take bug reports. + +Use the file ``/proc/sys/kernel/kmemcheck`` for this purpose, e.g.:: + + $ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck + +The numbers are the same as for the ``kmemcheck=`` command-line option. + + +Debugging +~~~~~~~~~ + +A typical report will look something like this:: + + WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024) + 80000000000000000000000000000000000000000088ffff0000000000000000 + i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u + ^ + + Pid: 1856, comm: ntpdate Not tainted 2.6.29-rc5 #264 945P-A + RIP: 0010:[] [] __dequeue_signal+0xc8/0x190 + RSP: 0018:ffff88003cdf7d98 EFLAGS: 00210002 + RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009 + RDX: ffff88003e5d6018 RSI: ffff88003e5d6024 RDI: ffff88003cdf7e84 + RBP: ffff88003cdf7db8 R08: ffff88003e5d6000 R09: 0000000000000000 + R10: 0000000000000080 R11: 0000000000000000 R12: 000000000000000e + R13: ffff88003cdf7e78 R14: ffff88003d530710 R15: ffff88003d5a98c8 + FS: 0000000000000000(0000) GS:ffff880001982000(0063) knlGS:00000 + CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 + CR2: ffff88003f806ea0 CR3: 000000003c036000 CR4: 00000000000006a0 + DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 + DR3: 0000000000000000 DR6: 00000000ffff4ff0 DR7: 0000000000000400 + [] dequeue_signal+0x8e/0x170 + [] get_signal_to_deliver+0x98/0x390 + [] do_notify_resume+0xad/0x7d0 + [] int_signal+0x12/0x17 + [] 0xffffffffffffffff + +The single most valuable information in this report is the RIP (or EIP on 32- +bit) value.

If not, the line number information will almost certainly be +wrong. + +The "``-i``" tells addr2line to also print the line numbers of inlined +functions. In this case, the flag was very important, because otherwise, +it would only have printed the first line, which is just a call to +``memcpy()``, which could be called from a thousand places in the kernel, and +is therefore not very useful. These inlined functions would not show up in +the stack trace above, simply because the kernel doesn't load the extra +debugging information. This technique can of course be used with ordinary +kernel oopses as well. + +In this case, it's the caller of ``memcpy()`` that is interesting, and it can be +found in ``include/asm-generic/siginfo.h``, line 287:: + + 281 static inline void copy_siginfo(struct siginfo *to, struct siginfo *from) + 282 { + 283 if (from->si_code < 0) + 284 memcpy(to, from, sizeof(*to)); + 285 else + 286 /* _sigchld is currently the largest know union member */ + 287 memcpy(to, from, __ARCH_SI_PREAMBLE_SIZE + sizeof(from->_sifields._sigchld)); + 288 } + +Since this was a read (kmemcheck usually warns about reads only, though it can +warn about writes to unallocated or freed memory as well), it was probably the +"from" argument which contained some uninitialized bytes. Following the chain +of calls, we move upwards to see where "from" was allocated or initialized, +``kernel/signal.c``, line 380:: + + 359 static void collect_signal(int sig, struct sigpending *list, siginfo_t *info) + 360 { + ... + 367 list_for_each_entry(q, &list->list, list) { + 368 if (q->info.si_signo == sig) { + 369 if (first) + 370 goto still_pending; + 371 first = q; + ... + 377 if (first) { + 378 still_pending: + 379 list_del_init(&first->list); + 380 copy_siginfo(info, &first->info); + 381 __sigqueue_free(first); + ... + 392 } + 393 } + +Here, it is ``&first->info`` that is being passed on to ``copy_siginfo()``. The +variable ``first`` was found on a list -- passed in as the second argument to +``collect_signal()``. We continue our journey through the stack, to figure out +where the item on "list" was allocated or initialized.

It seems that now is the time to look at the definition of +``struct sigqueue``, e.g.:: + + 14 struct sigqueue { + 15 struct list_head list; + 16 int flags; + 17 siginfo_t info; + 18 struct user_struct *user; + 19 }; + +And, you might remember, it was a ``memcpy()`` on ``&first->info`` that +caused the warning, so this makes perfect sense. It also seems reasonable +to assume that it is the caller of ``__sigqueue_alloc()`` that has the +responsibility of filling out (initializing) this member. + +But just which fields of the struct were uninitialized? Let's look at +kmemcheck's report again:: + + WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024) + 80000000000000000000000000000000000000000088ffff0000000000000000 + i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u + ^ + +These first two lines are the memory dump of the memory object itself, and +the shadow bytemap, respectively.

We know about ``REP MOVSL`` that it uses the register +``RCX`` to count the number of remaining iterations. By taking a look at the +register dump again (from the kmemcheck report), we can figure out how many +bytes were left to copy:: + + RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009 + +By looking at the disassembly, we also see that ``%ecx`` is being loaded +with the value ``$0xc`` just before (ffffffff8104edd8), so we are very +lucky. Keep in mind that this is the number of iterations, not bytes. And +since this is a "long" operation, we need to multiply by 4 to get the +number of bytes. So this means that the uninitialized value was encountered +at 4 * (0xc - 0x9) = 12 bytes from the start of the object. + +We can now try to figure out which field of the "``struct siginfo``" that +was not initialized. This is the beginning of the struct:: + + 40 typedef struct siginfo { + 41 int si_signo; + 42 int si_errno; + 43 int si_code; + 44 + 45 union { + .. + 92 } _sifields; + 93 } siginfo_t; + +On 64-bit, the int is 4 bytes long, so it must the union member that has +not been initialized. We can verify this using gdb:: + + $ gdb vmlinux + ... + (gdb) p &((struct siginfo *) 0)->_sifields + $1 = (union {...} *) 0x10 + +Actually, it seems that the union member is located at offset 0x10 -- which +means that gcc has inserted 4 bytes of padding between the members ``si_code`` +and ``_sifields``. We can now get a fuller picture of the memory dump:: + + _----------------------------=> si_code + / _--------------------=> (padding) + | / _------------=> _sifields(._kill._pid) + | | / _----=> _sifields(._kill._uid) + | | | / + -------|-------|-------|-------| + 80000000000000000000000000000000000000000088ffff0000000000000000 + i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u + +This allows us to realize another important fact: ``si_code`` contains the +value 0x80. Remember that x86 is little endian, so the first 4 bytes +"80000000" are really the number 0x00000080. With a bit of research, we +find that this is actually the constant ``SI_KERNEL`` defined in +``include/asm-generic/siginfo.h``:: + + 144 #define SI_KERNEL 0x80 /* sent by the kernel from somewhere */ + +This macro is used in exactly one place in the x86 kernel: In ``send_signal()`` +in ``kernel/signal.c``:: + + 816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t, + 817 int group) + 818 { + ... + 828 pending = group ? &t->signal->shared_pending : &t->pending; + ... + 851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN && + 852 (is_si_special(info) || + 853 info->si_code >= 0))); + 854 if (q) { + 855 list_add_tail(&q->list, &pending->list); + 856 switch ((unsigned long) info) { + ... + 865 case (unsigned long) SEND_SIG_PRIV: + 866 q->info.si_signo = sig; + 867 q->info.si_errno = 0; + 868 q->info.si_code = SI_KERNEL; + 869 q->info.si_pid = 0; + 870 q->info.si_uid = 0; + 871 break; + ... + 890 } + +Not only does this match with the ``.si_code`` member, it also matches the place +we found earlier when looking for where siginfo_t objects are enqueued on the +``shared_pending`` list. + +So to sum up: It seems that it is the padding introduced by the compiler +between two struct fields that is uninitialized, and this gets reported when +we do a ``memcpy()`` on the struct. This means that we have identified a false +positive warning. + +Normally, kmemcheck will not report uninitialized accesses in ``memcpy()`` calls +when both the source and destination addresses are tracked. (Instead, we copy +the shadow bytemap as well). In this case, the destination address clearly +was not tracked. We can dig a little deeper into the stack trace from above:: + + arch/x86/kernel/signal.c:805 + arch/x86/kernel/signal.c:871 + arch/x86/kernel/entry_64.S:694 + +And we clearly see that the destination siginfo object is located on the +stack:: + + 782 static void do_signal(struct pt_regs *regs) + 783 { + 784 struct k_sigaction ka; + 785 siginfo_t info; + ... + 804 signr = get_signal_to_deliver(&info, &ka, regs, NULL); + ... + 854 } + +And this ``&info`` is what eventually gets passed to ``copy_siginfo()`` as the +destination argument. + +Now, even though we didn't find an actual error here, the example is still a +good one, because it shows how one would go about to find out what the report +was all about. + + +Annotating false positives +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There are a few different ways to make annotations in the source code that +will keep kmemcheck from checking and reporting certain allocations. Here +they are: + +- ``__GFP_NOTRACK_FALSE_POSITIVE`` + This flag can be passed to ``kmalloc()`` or ``kmem_cache_alloc()`` + (therefore also to other functions that end up calling one of + these) to indicate that the allocation should not be tracked + because it would lead to a false positive report. This is a "big + hammer" way of silencing kmemcheck; after all, even if the false + positive pertains to particular field in a struct, for example, we + will now lose the ability to find (real) errors in other parts of + the same struct. + + Example:: + + /* No warnings will ever trigger on accessing any part of x */ + x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE); + +- ``kmemcheck_bitfield_begin(name)``/``kmemcheck_bitfield_end(name)`` and + ``kmemcheck_annotate_bitfield(ptr, name)`` + The first two of these three macros can be used inside struct + definitions to signal, respectively, the beginning and end of a + bitfield. Additionally, this will assign the bitfield a name, which + is given as an argument to the macros. + + Having used these markers, one can later use + kmemcheck_annotate_bitfield() at the point of allocation, to indicate + which parts of the allocation is part of a bitfield. + + Example:: + + struct foo { + int x; + + kmemcheck_bitfield_begin(flags); + int flag_a:1; + int flag_b:1; + kmemcheck_bitfield_end(flags); + + int y; + }; + + struct foo *x = kmalloc(sizeof *x); + + /* No warnings will trigger on accessing the bitfield of x */ + kmemcheck_annotate_bitfield(x, flags); + + Note that ``kmemcheck_annotate_bitfield()`` can be used even before the + return value of ``kmalloc()`` is checked -- in other words, passing NULL + as the first argument is legal (and will do nothing). + + +Reporting errors +---------------- + +As we have seen, kmemcheck will produce false positive reports. Therefore, it +is not very wise to blindly post kmemcheck warnings to mailing lists and +maintainers. Instead, I encourage maintainers and developers to find errors +in their own code. If you get a warning, you can try to work around it, try +to figure out if it's a real error or not, or simply ignore it. Most +developers know their own code and will quickly and efficiently determine the +root cause of a kmemcheck report. This is therefore also the most efficient +way to work with kmemcheck. + +That said, we (the kmemcheck maintainers) will always be on the lookout for +false positives that we can annotate and silence. So whatever you find, +please drop us a note privately! Kernel configs and steps to reproduce (if +available) are of course a great help too. + +Happy hacking! + + +Technical description +--------------------- + +kmemcheck works by marking memory pages non-present. This means that whenever +somebody attempts to access the page, a page fault is generated. The page +fault handler notices that the page was in fact only hidden, and so it calls +on the kmemcheck code to make further investigations. + +When the investigations are completed, kmemcheck "shows" the page by marking +it present (as it would be under normal circumstances). This way, the +interrupted code can continue as usual. + +But after the instruction has been executed, we should hide the page again, so +that we can catch the next access too! Now kmemcheck makes use of a debugging +feature of the processor, namely single-stepping. When the processor has +finished the one instruction that generated the memory access, a debug +exception is raised. From here, we simply hide the page again and continue +execution, this time with the single-stepping feature turned off. + +kmemcheck requires some assistance from the memory allocator in order to work. +The memory allocator needs to + + 1. Tell kmemcheck about newly allocated pages and pages that are about to + be freed. This allows kmemcheck to set up and tear down the shadow memory + for the pages in question. The shadow memory stores the status of each + byte in the allocation proper, e.g. whether it is initialized or + uninitialized. + + 2. Tell kmemcheck which parts of memory should be marked uninitialized. + There are actually a few more states, such as "not yet allocated" and + "recently freed". + +If a slab cache is set up using the SLAB_NOTRACK flag, it will never return +memory that can take page faults because of kmemcheck. + +If a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still +request memory with the __GFP_NOTRACK or __GFP_NOTRACK_FALSE_POSITIVE flags. +This does not prevent the page faults from occurring, however, but marks the +object in question as being initialized so that no warnings will ever be +produced for this object. + +Currently, the SLAB and SLUB allocators are supported by kmemcheck. diff --git a/Documentation/kmemleak.txt b/Documentation/dev-tools/kmemleak.rst similarity index 71% rename from Documentation/kmemleak.txt rename to Documentation/dev-tools/kmemleak.rst index 18e24abb3ecf..b2391b829169 100644 --- a/Documentation/kmemleak.txt +++ b/Documentation/dev-tools/kmemleak.rst @@ -1,15 +1,12 @@ Kernel Memory Leak Detector =========================== -Introduction ------------- - Kmemleak provides a way of detecting possible kernel memory leaks in a way similar to a tracing garbage collector (https://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29#Tracing_garbage_collectors), with the difference that the orphan objects are not freed but only reported via /sys/kernel/debug/kmemleak.

Also CONFIG_GCOV_PROFILE_ALL may not be supported -on all architectures. - -Profiling data will only become accessible once debugfs has been -mounted: - - mount -t debugfs none /sys/kernel/debug - - -3. Customization -================ - -To enable profiling for specific files or directories, add a line -similar to the following to the respective kernel Makefile: - - For a single file (e.g. main.o): - GCOV_PROFILE_main.o := y - - For all files in one directory: - GCOV_PROFILE := y - -To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL -is specified, use: - - GCOV_PROFILE_main.o := n - and: - GCOV_PROFILE := n - -Only files which are linked to the main kernel image or are compiled as -kernel modules are supported by this mechanism. - - -4. Files -======== - -The gcov kernel support creates the following files in debugfs: - - /sys/kernel/debug/gcov - Parent directory for all gcov-related files. - - /sys/kernel/debug/gcov/reset - Global reset file: resets all coverage data to zero when - written to. - - /sys/kernel/debug/gcov/path/to/compile/dir/file.gcda - The actual gcov data file as understood by the gcov - tool.

The gcov mechanism provides a means to collect -coverage data for such code by keeping a copy of the data associated -with the unloaded module.

Separated build and test machines -==================================== - -The gcov kernel profiling infrastructure is designed to work out-of-the -box for setups where kernels are built and run on the same machine.

This section here +explains what exactly those requirements are, and why they exist. + +The short summary is that any addition of DRM uAPI requires corresponding +open-sourced userspace patches, and those patches must be reviewed and ready for +merging into a suitable and canonical upstream project. + +GFX devices (both display and render/GPU side) are really complex bits of +hardware, with userspace and kernel by necessity having to work together really +closely. The interfaces, for rendering and modesetting, must be extremely wide +and flexible, and therefore it is almost always impossible to precisely define +them for every possible corner case. This in turn makes it really practically +infeasible to differentiate between behaviour that's required by userspace, and +which must not be changed to avoid regressions, and behaviour which is only an +accidental artifact of the current implementation. + +Without access to the full source code of all userspace users that means it +becomes impossible to change the implementation details, since userspace could +depend upon the accidental behaviour of the current implementation in minute +details. And debugging such regressions without access to source code is pretty +much impossible. As a consequence this means: + +- The Linux kernel's "no regression" policy holds in practice only for + open-source userspace of the DRM subsystem. DRM developers are perfectly fine + if closed-source blob drivers in userspace use the same uAPI as the open + drivers, but they must do so in the exact same way as the open drivers. + Creative (ab)use of the interfaces will, and in the past routinely has, lead + to breakage. + +- Any new userspace interface must have an open-source implementation as + demonstration vehicle. + +The other reason for requiring open-source userspace is uAPI review.

Specifically it needs to handle all the usual error and corner cases. + These are often the places where new uAPI falls apart and hence essential to + assess the fitness of a proposed interface. + +- The userspace side must be fully reviewed and tested to the standards of that + userspace project.

Doorbell +register has the following format: +Bits 0..6: fragment length (7 bits are used) +Bits 10..13: encapsulated protocol +Bits 16..19: management command (for IPC management protocol) +Bit 31: doorbell trigger (signal H/W interrupt to the other side) +Other bits are reserved, should be 0. + +3.2.2 Transport layer interface + +To abstract HW level IPC communication, a set of callbacks are registered. +The transport layer uses them to send and receive messages. +Refer to struct ishtp_hw_ops for callbacks. + +3.3 ISH Transport layer +Location: drivers/hid/intel-ish-hid/ishtp/ + +3.3.1 A Generic Transport Layer + +The transport layer is a bi-directional protocol, which defines: +- Set of commands to start, stop, connect, disconnect and flow control +(ishtp/hbm.h) for details +- A flow control mechanism to avoid buffer overflows + +This protocol resembles bus messages described in the following document: +http://www.intel.com/content/dam/www/public/us/en/documents/technical-\ +specifications/dcmi-hi-1-0-spec.pdf "Chapter 7: Bus Message Layer" + +3.3.2 Connection and Flow Control Mechanism + +Each FW client and a protocol is identified by an UUID. In order to communicate +to a FW client, a connection must be established using connect request and +response bus messages. If successful, a pair (host_client_id and fw_client_id) +will identify the connection. + +Once connection is established, peers send each other flow control bus messages +independently. Every peer may send a message only if it has received a +flow-control credit before. Once it sent a message, it may not send another one +before receiving the next flow control credit. +Either side can send disconnect request bus message to end communication. Also +the link will be dropped if major FW reset occurs. + +3.3.3 Peer to Peer data transfer + +Peer to Peer data transfer can happen with or without using DMA. Depending on +the sensor bandwidth requirement DMA can be enabled by using module parameter +ishtp_use_dma under intel_ishtp. + +Each side (host and FW) manages its DMA transfer memory independently. When an +ISHTP client from either host or FW side wants to send something, it decides +whether to send over IPC or over DMA; for each transfer the decision is +independent. The sending side sends DMA_XFER message when the message is in +the respective host buffer (TX when host client sends, RX when FW client +sends). The recipient of DMA message responds with DMA_XFER_ACK, indicating +the sender that the memory region for that message may be reused. + +DMA initialization is started with host sending DMA_ALLOC_NOTIFY bus message +(that includes RX buffer) and FW responds with DMA_ALLOC_NOTIFY_ACK. +Additionally to DMA address communication, this sequence checks capabilities: +if thw host doesn't support DMA, then it won't send DMA allocation, so FW can't +send DMA; if FW doesn't support DMA then it won't respond with +DMA_ALLOC_NOTIFY_ACK, in which case host will not use DMA transfers. +Here ISH acts as busmaster DMA controller. Hence when host sends DMA_XFER, +it's request to do host->ISH DMA transfer; when FW sends DMA_XFER, it means +that it already did DMA and the message resides at host. Thus, DMA_XFER +and DMA_XFER_ACK act as ownership indicators. + +At initial state all outgoing memory belongs to the sender (TX to host, RX to +FW), DMA_XFER transfers ownership on the region that contains ISHTP message to +the receiving side, DMA_XFER_ACK returns ownership to the sender. A sender +needs not wait for previous DMA_XFER to be ack'ed, and may send another message +as long as remaining continuous memory in its ownership is enough. +In principle, multiple DMA_XFER and DMA_XFER_ACK messages may be sent at once +(up to IPC MTU), thus allowing for interrupt throttling. +Currently, ISH FW decides to send over DMA if ISHTP message is more than 3 IPC +fragments and via IPC otherwise. + +3.3.4 Ring Buffers + +When a client initiate a connection, a ring or RX and TX buffers are allocated. +The size of ring can be specified by the client. HID client set 16 and 32 for +TX and RX buffers respectively. On send request from client, the data to be +sent is copied to one of the send ring buffer and scheduled to be sent using +bus message protocol. These buffers are required because the FW may have not +have processed the last message and may not have enough flow control credits +to send. Same thing holds true on receive side and flow control is required. + +3.3.5 Host Enumeration + +The host enumeration bus command allow discovery of clients present in the FW. +There can be multiple sensor clients and clients for calibration function. + +To ease in implantation and allow independent driver handle each client +this transport layer takes advantage of Linux Bus driver model. Each +client is registered as device on the the transport bus (ishtp bus). + +Enumeration sequence of messages: +- Host sends HOST_START_REQ_CMD, indicating that host ISHTP layer is up. +- FW responds with HOST_START_RES_CMD +- Host sends HOST_ENUM_REQ_CMD (enumerate FW clients) +- FW responds with HOST_ENUM_RES_CMD that includes bitmap of available FW +client IDs +- For each FW ID found in that bitmap host sends +HOST_CLIENT_PROPERTIES_REQ_CMD +- FW responds with HOST_CLIENT_PROPERTIES_RES_CMD. Properties include UUID, +max ISHTP message size, etc. +- Once host received properties for that last discovered client, it considers +ISHTP device fully functional (and allocates DMA buffers) + +3.4 HID over ISH Client +Location: drivers/hid/intel-ish-hid + +The ISHTP client driver is responsible for: +- enumerate HID devices under FW ISH client +- Get Report descriptor +- Register with HID core as a LL driver +- Process Get/Set feature request +- Get input reports + +3.5 HID Sensor Hub MFD and IIO sensor drivers + +The functionality in these drivers is the same as an external sensor hub. +Refer to +Documentation/hid/hid-sensor.txt for HID sensor +Documentation/ABI/testing/sysfs-bus-iio for IIO ABIs to user space + +3.6 End to End HID transport Sequence Diagram + +HID-ISH-CLN ISHTP IPC HW + | | | | + | | |-----WAKE UP------------------>| + | | | | + | | |-----HOST READY--------------->| + | | | | + | | |<----MNG_RESET_NOTIFY_ACK----- | + | | | | + | |<----ISHTP_START------ | | + | | | | + | |<-----------------HOST_START_RES_CMD-------------------| + | | | | + | |------------------QUERY_SUBSCRIBER-------------------->| + | | | | + | |------------------HOST_ENUM_REQ_CMD------------------->| + | | | | + | |<-----------------HOST_ENUM_RES_CMD--------------------| + | | | | + | |------------------HOST_CLIENT_PROPERTIES_REQ_CMD------>| + | | | | + | |<-----------------HOST_CLIENT_PROPERTIES_RES_CMD-------| + | Create new device on in ishtp bus | | + | | | | + | |------------------HOST_CLIENT_PROPERTIES_REQ_CMD------>| + | | | | + | |<-----------------HOST_CLIENT_PROPERTIES_RES_CMD-------| + | Create new device on in ishtp bus | | + | | | | + | |--Repeat HOST_CLIENT_PROPERTIES_REQ_CMD-till last one--| + | | | | + probed() + |----ishtp_cl_connect-->|----------------- CLIENT_CONNECT_REQ_CMD-------------->| + | | | | + | |<----------------CLIENT_CONNECT_RES_CMD----------------| + | | | | + |register event callback| | | + | | | | + |ishtp_cl_send( + HOSTIF_DM_ENUM_DEVICES) |----------fill ishtp_msg_hdr struct write to HW----- >| + | | | | + | | |<-----IRQ(IPC_PROTOCOL_ISHTP---| + | | | | + |<--ENUM_DEVICE RSP-----| | | + | | | | +for each enumerated device + |ishtp_cl_send( + HOSTIF_GET_HID_DESCRIPTOR |----------fill ishtp_msg_hdr struct write to HW--- >| + | | | | + ...Response + | | | | +for each enumerated device + |ishtp_cl_send( + HOSTIF_GET_REPORT_DESCRIPTOR |----------fill ishtp_msg_hdr struct write to HW- >| + | | | | + | | | | + hid_allocate_device + | | | | + hid_add_device | | | + | | | | + + +3.7 ISH Debugging + +To debug ISH, event tracing mechanism is used.

But reading the sources is not always +enough. It is easy to understand the code, but miss the concepts, the +philosophy and design decisions behind this code. + +Unfortunately, not many documents are available for beginners to +start. And, even if they exist, there was no "well-known" place which +kept track of them. These lines try to cover this lack. All documents +available on line known by the author are listed, while some reference +books are also mentioned. + +PLEASE, if you know any paper not listed here or write a new document, +send me an e-mail, and I'll include a reference to it here. Any +corrections, ideas or comments are also welcomed. + +The papers that follow are listed in no particular order. All are +cataloged with the following fields: the document's "Title", the +"Author"/s, the "URL" where they can be found, some "Keywords" helpful +when searching for specific topics, and a brief "Description" of the +Document. + +Enjoy! + +.. note:: + + The documents on each section of this document are ordered by its + published date, from the newest to the oldest. + +Docs at the Linux Kernel tree +----------------------------- + +The DocBook books should be built with ``make {htmldocs | psdocs | pdfdocs}``. +The Sphinx books should be built with ``make {htmldocs | pdfdocs | epubdocs}``. + + * Name: **linux/Documentation** + + :Author: Many. + :Location: Documentation/ + :Keywords: text files, Sphinx, DocBook. + :Description: Documentation that comes with the kernel sources, + inside the Documentation directory.

Technical description - - -0. Introduction -=============== - -kmemcheck is a debugging feature for the Linux Kernel. More specifically, it -is a dynamic checker that detects and warns about some uses of uninitialized -memory. - -Userspace programmers might be familiar with Valgrind's memcheck. The main -difference between memcheck and kmemcheck is that memcheck works for userspace -programs only, and kmemcheck works for the kernel only. The implementations -are of course vastly different. Because of this, kmemcheck is not as accurate -as memcheck, but it turns out to be good enough in practice to discover real -programmer errors that the compiler is not able to find through static -analysis. - -Enabling kmemcheck on a kernel will probably slow it down to the extent that -the machine will not be usable for normal workloads such as e.g. an -interactive desktop. kmemcheck will also cause the kernel to use about twice -as much memory as normal. For this reason, kmemcheck is strictly a debugging -feature. - - -1. Downloading -============== - -As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel. - - -2. Configuring and compiling -============================ - -kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of -configuration variables must have specific settings in order for the kmemcheck -menu to even appear in "menuconfig". These are: - - o CONFIG_CC_OPTIMIZE_FOR_SIZE=n - - This option is located under "General setup" / "Optimize for size". - - Without this, gcc will use certain optimizations that usually lead to - false positive warnings from kmemcheck. An example of this is a 16-bit - field in a struct, where gcc may load 32 bits, then discard the upper - 16 bits. kmemcheck sees only the 32-bit load, and may trigger a - warning for the upper 16 bits (if they're uninitialized). - - o CONFIG_SLAB=y or CONFIG_SLUB=y - - This option is located under "General setup" / "Choose SLAB - allocator". - - o CONFIG_FUNCTION_TRACER=n - - This option is located under "Kernel hacking" / "Tracers" / "Kernel - Function Tracer" - - When function tracing is compiled in, gcc emits a call to another - function at the beginning of every function. This means that when the - page fault handler is called, the ftrace framework will be called - before kmemcheck has had a chance to handle the fault. If ftrace then - modifies memory that was tracked by kmemcheck, the result is an - endless recursive page fault. - - o CONFIG_DEBUG_PAGEALLOC=n - - This option is located under "Kernel hacking" / "Memory Debugging" - / "Debug page memory allocations". - -In addition, I highly recommend turning on CONFIG_DEBUG_INFO=y. This is also -located under "Kernel hacking". With this, you will be able to get line number -information from the kmemcheck warnings, which is extremely valuable in -debugging a problem. This option is not mandatory, however, because it slows -down the compilation process and produces a much bigger kernel image. - -Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory -Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows -a description of the kmemcheck configuration variables: - - o CONFIG_KMEMCHECK - - This must be enabled in order to use kmemcheck at all... - - o CONFIG_KMEMCHECK_[DISABLED | ENABLED | ONESHOT]_BY_DEFAULT - - This option controls the status of kmemcheck at boot-time. "Enabled" - will enable kmemcheck right from the start, "disabled" will boot the - kernel as normal (but with the kmemcheck code compiled in, so it can - be enabled at run-time after the kernel has booted), and "one-shot" is - a special mode which will turn kmemcheck off automatically after - detecting the first use of uninitialized memory. - - If you are using kmemcheck to actively debug a problem, then you - probably want to choose "enabled" here. - - The one-shot mode is mostly useful in automated test setups because it - can prevent floods of warnings and increase the chances of the machine - surviving in case something is really wrong. In other cases, the one- - shot mode could actually be counter-productive because it would turn - itself off at the very first error -- in the case of a false positive - too -- and this would come in the way of debugging the specific - problem you were interested in. - - If you would like to use your kernel as normal, but with a chance to - enable kmemcheck in case of some problem, it might be a good idea to - choose "disabled" here. When kmemcheck is disabled, most of the run- - time overhead is not incurred, and the kernel will be almost as fast - as normal. - - o CONFIG_KMEMCHECK_QUEUE_SIZE - - Select the maximum number of error reports to store in an internal - (fixed-size) buffer. Since errors can occur virtually anywhere and in - any context, we need a temporary storage area which is guaranteed not - to generate any other page faults when accessed. The queue will be - emptied as soon as a tasklet may be scheduled. If the queue is full, - new error reports will be lost. - - The default value of 64 is probably fine. If some code produces more - than 64 errors within an irqs-off section, then the code is likely to - produce many, many more, too, and these additional reports seldom give - any more information (the first report is usually the most valuable - anyway). - - This number might have to be adjusted if you are not using serial - console or similar to capture the kernel log. If you are using the - "dmesg" command to save the log, then getting a lot of kmemcheck - warnings might overflow the kernel log itself, and the earlier reports - will get lost in that way instead. Try setting this to 10 or so on - such a setup. - - o CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT - - Select the number of shadow bytes to save along with each entry of the - error-report queue. These bytes indicate what parts of an allocation - are initialized, uninitialized, etc. and will be displayed when an - error is detected to help the debugging of a particular problem. - - The number entered here is actually the logarithm of the number of - bytes that will be saved. So if you pick for example 5 here, kmemcheck - will save 2^5 = 32 bytes. - - The default value should be fine for debugging most problems. It also - fits nicely within 80 columns. - - o CONFIG_KMEMCHECK_PARTIAL_OK - - This option (when enabled) works around certain GCC optimizations that - produce 32-bit reads from 16-bit variables where the upper 16 bits are - thrown away afterwards. - - The default value (enabled) is recommended. This may of course hide - some real errors, but disabling it would probably produce a lot of - false positives. - - o CONFIG_KMEMCHECK_BITOPS_OK - - This option silences warnings that would be generated for bit-field - accesses where not all the bits are initialized at the same time. This - may also hide some real bugs. - - This option is probably obsolete, or it should be replaced with - the kmemcheck-/bitfield-annotations for the code in question. The - default value is therefore fine. - -Now compile the kernel as usual. - - -3. How to use -============= - -3.1. Booting -============ - -First some information about the command-line options. There is only one -option specific to kmemcheck, and this is called "kmemcheck". It can be used -to override the default mode as chosen by the CONFIG_KMEMCHECK_*_BY_DEFAULT -option. Its possible settings are: - - o kmemcheck=0 (disabled) - o kmemcheck=1 (enabled) - o kmemcheck=2 (one-shot mode) - -If SLUB debugging has been enabled in the kernel, it may take precedence over -kmemcheck in such a way that the slab caches which are under SLUB debugging -will not be tracked by kmemcheck. In order to ensure that this doesn't happen -(even though it shouldn't by default), use SLUB's boot option "slub_debug", -like this: slub_debug=- - -In fact, this option may also be used for fine-grained control over SLUB vs. -kmemcheck. For example, if the command line includes "kmemcheck=1 -slub_debug=,dentry", then SLUB debugging will be used only for the "dentry" -slab cache, and with kmemcheck tracking all the other caches. This is advanced -usage, however, and is not generally recommended. - - -3.2. Run-time enable/disable -============================ - -When the kernel has booted, it is possible to enable or disable kmemcheck at -run-time. WARNING: This feature is still experimental and may cause false -positive warnings to appear. Therefore, try not to use this. If you find that -it doesn't work properly (e.g. you see an unreasonable amount of warnings), I -will be happy to take bug reports. - -Use the file /proc/sys/kernel/kmemcheck for this purpose, e.g.: - - $ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck - -The numbers are the same as for the kmemcheck= command-line option. - - -3.3. Debugging -============== - -A typical report will look something like this: - -WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024) -80000000000000000000000000000000000000000088ffff0000000000000000 - i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u - ^ - -Pid: 1856, comm: ntpdate Not tainted 2.6.29-rc5 #264 945P-A -RIP: 0010:[] [] __dequeue_signal+0xc8/0x190 -RSP: 0018:ffff88003cdf7d98 EFLAGS: 00210002 -RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009 -RDX: ffff88003e5d6018 RSI: ffff88003e5d6024 RDI: ffff88003cdf7e84 -RBP: ffff88003cdf7db8 R08: ffff88003e5d6000 R09: 0000000000000000 -R10: 0000000000000080 R11: 0000000000000000 R12: 000000000000000e -R13: ffff88003cdf7e78 R14: ffff88003d530710 R15: ffff88003d5a98c8 -FS: 0000000000000000(0000) GS:ffff880001982000(0063) knlGS:00000 -CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 -CR2: ffff88003f806ea0 CR3: 000000003c036000 CR4: 00000000000006a0 -DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 -DR3: 0000000000000000 DR6: 00000000ffff4ff0 DR7: 0000000000000400 - [] dequeue_signal+0x8e/0x170 - [] get_signal_to_deliver+0x98/0x390 - [] do_notify_resume+0xad/0x7d0 - [] int_signal+0x12/0x17 - [] 0xffffffffffffffff - -The single most valuable information in this report is the RIP (or EIP on 32- -bit) value.

We inspect the line numbers more closely -and find that this is indeed where items are being added to the list: - -816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t, -817 int group) -818 { -... -828 pending = group ? &t->signal->shared_pending : &t->pending; -... -851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN && -852 (is_si_special(info) || -853 info->si_code >= 0))); -854 if (q) { -855 list_add_tail(&q->list, &pending->list); -... -890 } - -and: - -1309 int send_sigqueue(struct sigqueue *q, struct task_struct *t, int group) -1310 { -.... -1339 pending = group ? &t->signal->shared_pending : &t->pending; -1340 list_add_tail(&q->list, &pending->list); -.... -1347 } - -In the first case, the list element we are looking for, "q", is being returned -from the function __sigqueue_alloc(), which looks like an allocation function. -Let's take a look at it: - -187 static struct sigqueue *__sigqueue_alloc(struct task_struct *t, gfp_t flags, -188 int override_rlimit) -189 { -190 struct sigqueue *q = NULL; -191 struct user_struct *user; -192 -193 /* -194 * We won't get problems with the target's UID changing under us -195 * because changing it requires RCU be used, and if t != current, the -196 * caller must be holding the RCU readlock (by way of a spinlock) and -197 * we use RCU protection here -198 */ -199 user = get_uid(__task_cred(t)->user); -200 atomic_inc(&user->sigpending); -201 if (override_rlimit || -202 atomic_read(&user->sigpending) <= -203 t->signal->rlim[RLIMIT_SIGPENDING].rlim_cur) -204 q = kmem_cache_alloc(sigqueue_cachep, flags); -205 if (unlikely(q == NULL)) { -206 atomic_dec(&user->sigpending); -207 free_uid(user); -208 } else { -209 INIT_LIST_HEAD(&q->list); -210 q->flags = 0; -211 q->user = user; -212 } -213 -214 return q; -215 } - -We see that this function initializes q->list, q->flags, and q->user. It seems -that now is the time to look at the definition of "struct sigqueue", e.g.: - -14 struct sigqueue { -15 struct list_head list; -16 int flags; -17 siginfo_t info; -18 struct user_struct *user; -19 }; - -And, you might remember, it was a memcpy() on &first->info that caused the -warning, so this makes perfect sense. It also seems reasonable to assume that -it is the caller of __sigqueue_alloc() that has the responsibility of filling -out (initializing) this member. - -But just which fields of the struct were uninitialized? Let's look at -kmemcheck's report again: - -WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024) -80000000000000000000000000000000000000000088ffff0000000000000000 - i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u - ^ - -These first two lines are the memory dump of the memory object itself, and the -shadow bytemap, respectively. The memory object itself is in this case -&first->info. Just beware that the start of this dump is NOT the start of the -object itself! The position of the caret (^) corresponds with the address of -the read (ffff88003e4a2024). - -The shadow bytemap dump legend is as follows: - - i - initialized - u - uninitialized - a - unallocated (memory has been allocated by the slab layer, but has not - yet been handed off to anybody) - f - freed (memory has been allocated by the slab layer, but has been freed - by the previous owner) - -In order to figure out where (relative to the start of the object) the -uninitialized memory was located, we have to look at the disassembly. For -that, we'll need the RIP address again: - -RIP: 0010:[] [] __dequeue_signal+0xc8/0x190 - - $ objdump -d --no-show-raw-insn vmlinux | grep -C 8 ffffffff8104ede8: - ffffffff8104edc8: mov %r8,0x8(%r8) - ffffffff8104edcc: test %r10d,%r10d - ffffffff8104edcf: js ffffffff8104ee88 <__dequeue_signal+0x168> - ffffffff8104edd5: mov %rax,%rdx - ffffffff8104edd8: mov $0xc,%ecx - ffffffff8104eddd: mov %r13,%rdi - ffffffff8104ede0: mov $0x30,%eax - ffffffff8104ede5: mov %rdx,%rsi - ffffffff8104ede8: rep movsl %ds:(%rsi),%es:(%rdi) - ffffffff8104edea: test $0x2,%al - ffffffff8104edec: je ffffffff8104edf0 <__dequeue_signal+0xd0> - ffffffff8104edee: movsw %ds:(%rsi),%es:(%rdi) - ffffffff8104edf0: test $0x1,%al - ffffffff8104edf2: je ffffffff8104edf5 <__dequeue_signal+0xd5> - ffffffff8104edf4: movsb %ds:(%rsi),%es:(%rdi) - ffffffff8104edf5: mov %r8,%rdi - ffffffff8104edf8: callq ffffffff8104de60 <__sigqueue_free> - -As expected, it's the "rep movsl" instruction from the memcpy() that causes -the warning. We know about REP MOVSL that it uses the register RCX to count -the number of remaining iterations. By taking a look at the register dump -again (from the kmemcheck report), we can figure out how many bytes were left -to copy: - -RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009 - -By looking at the disassembly, we also see that %ecx is being loaded with the -value $0xc just before (ffffffff8104edd8), so we are very lucky. Keep in mind -that this is the number of iterations, not bytes. And since this is a "long" -operation, we need to multiply by 4 to get the number of bytes. So this means -that the uninitialized value was encountered at 4 * (0xc - 0x9) = 12 bytes -from the start of the object. - -We can now try to figure out which field of the "struct siginfo" that was not -initialized. This is the beginning of the struct: - -40 typedef struct siginfo { -41 int si_signo; -42 int si_errno; -43 int si_code; -44 -45 union { -.. -92 } _sifields; -93 } siginfo_t; - -On 64-bit, the int is 4 bytes long, so it must the union member that has -not been initialized. We can verify this using gdb: - - $ gdb vmlinux - ... - (gdb) p &((struct siginfo *) 0)->_sifields - $1 = (union {...} *) 0x10 - -Actually, it seems that the union member is located at offset 0x10 -- which -means that gcc has inserted 4 bytes of padding between the members si_code -and _sifields. We can now get a fuller picture of the memory dump: - - _----------------------------=> si_code - / _--------------------=> (padding) - | / _------------=> _sifields(._kill._pid) - | | / _----=> _sifields(._kill._uid) - | | | / --------|-------|-------|-------| -80000000000000000000000000000000000000000088ffff0000000000000000 - i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u - -This allows us to realize another important fact: si_code contains the value -0x80. Remember that x86 is little endian, so the first 4 bytes "80000000" are -really the number 0x00000080. With a bit of research, we find that this is -actually the constant SI_KERNEL defined in include/asm-generic/siginfo.h: - -144 #define SI_KERNEL 0x80 /* sent by the kernel from somewhere */ - -This macro is used in exactly one place in the x86 kernel: In send_signal() -in kernel/signal.c: - -816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t, -817 int group) -818 { -... -828 pending = group ? &t->signal->shared_pending : &t->pending; -... -851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN && -852 (is_si_special(info) || -853 info->si_code >= 0))); -854 if (q) { -855 list_add_tail(&q->list, &pending->list); -856 switch ((unsigned long) info) { -... -865 case (unsigned long) SEND_SIG_PRIV: -866 q->info.si_signo = sig; -867 q->info.si_errno = 0; -868 q->info.si_code = SI_KERNEL; -869 q->info.si_pid = 0; -870 q->info.si_uid = 0; -871 break; -... -890 } - -Not only does this match with the .si_code member, it also matches the place -we found earlier when looking for where siginfo_t objects are enqueued on the -"shared_pending" list. - -So to sum up: It seems that it is the padding introduced by the compiler -between two struct fields that is uninitialized, and this gets reported when -we do a memcpy() on the struct. This means that we have identified a false -positive warning. - -Normally, kmemcheck will not report uninitialized accesses in memcpy() calls -when both the source and destination addresses are tracked. (Instead, we copy -the shadow bytemap as well). In this case, the destination address clearly -was not tracked. We can dig a little deeper into the stack trace from above: - - arch/x86/kernel/signal.c:805 - arch/x86/kernel/signal.c:871 - arch/x86/kernel/entry_64.S:694 - -And we clearly see that the destination siginfo object is located on the -stack: - -782 static void do_signal(struct pt_regs *regs) -783 { -784 struct k_sigaction ka; -785 siginfo_t info; -... -804 signr = get_signal_to_deliver(&info, &ka, regs, NULL); -... -854 } - -And this &info is what eventually gets passed to copy_siginfo() as the -destination argument. - -Now, even though we didn't find an actual error here, the example is still a -good one, because it shows how one would go about to find out what the report -was all about. - - -3.4. Annotating false positives -=============================== - -There are a few different ways to make annotations in the source code that -will keep kmemcheck from checking and reporting certain allocations. Here -they are: - - o __GFP_NOTRACK_FALSE_POSITIVE - - This flag can be passed to kmalloc() or kmem_cache_alloc() (therefore - also to other functions that end up calling one of these) to indicate - that the allocation should not be tracked because it would lead to - a false positive report. This is a "big hammer" way of silencing - kmemcheck; after all, even if the false positive pertains to - particular field in a struct, for example, we will now lose the - ability to find (real) errors in other parts of the same struct. - - Example: - - /* No warnings will ever trigger on accessing any part of x */ - x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE); - - o kmemcheck_bitfield_begin(name)/kmemcheck_bitfield_end(name) and - kmemcheck_annotate_bitfield(ptr, name) - - The first two of these three macros can be used inside struct - definitions to signal, respectively, the beginning and end of a - bitfield. Additionally, this will assign the bitfield a name, which - is given as an argument to the macros. - - Having used these markers, one can later use - kmemcheck_annotate_bitfield() at the point of allocation, to indicate - which parts of the allocation is part of a bitfield. - - Example: - - struct foo { - int x; - - kmemcheck_bitfield_begin(flags); - int flag_a:1; - int flag_b:1; - kmemcheck_bitfield_end(flags); - - int y; - }; - - struct foo *x = kmalloc(sizeof *x); - - /* No warnings will trigger on accessing the bitfield of x */ - kmemcheck_annotate_bitfield(x, flags); - - Note that kmemcheck_annotate_bitfield() can be used even before the - return value of kmalloc() is checked -- in other words, passing NULL - as the first argument is legal (and will do nothing). - - -4. Reporting errors -=================== - -As we have seen, kmemcheck will produce false positive reports. Therefore, it -is not very wise to blindly post kmemcheck warnings to mailing lists and -maintainers. Instead, I encourage maintainers and developers to find errors -in their own code. If you get a warning, you can try to work around it, try -to figure out if it's a real error or not, or simply ignore it. Most -developers know their own code and will quickly and efficiently determine the -root cause of a kmemcheck report. This is therefore also the most efficient -way to work with kmemcheck. - -That said, we (the kmemcheck maintainers) will always be on the lookout for -false positives that we can annotate and silence. So whatever you find, -please drop us a note privately! Kernel configs and steps to reproduce (if -available) are of course a great help too. - -Happy hacking! - - -5. Technical description -======================== - -kmemcheck works by marking memory pages non-present. This means that whenever -somebody attempts to access the page, a page fault is generated. The page -fault handler notices that the page was in fact only hidden, and so it calls -on the kmemcheck code to make further investigations. - -When the investigations are completed, kmemcheck "shows" the page by marking -it present (as it would be under normal circumstances). This way, the -interrupted code can continue as usual. - -But after the instruction has been executed, we should hide the page again, so -that we can catch the next access too! Now kmemcheck makes use of a debugging -feature of the processor, namely single-stepping. When the processor has -finished the one instruction that generated the memory access, a debug -exception is raised. From here, we simply hide the page again and continue -execution, this time with the single-stepping feature turned off. - -kmemcheck requires some assistance from the memory allocator in order to work. -The memory allocator needs to - - 1. Tell kmemcheck about newly allocated pages and pages that are about to - be freed. This allows kmemcheck to set up and tear down the shadow memory - for the pages in question. The shadow memory stores the status of each - byte in the allocation proper, e.g. whether it is initialized or - uninitialized. - - 2. Tell kmemcheck which parts of memory should be marked uninitialized. - There are actually a few more states, such as "not yet allocated" and - "recently freed". - -If a slab cache is set up using the SLAB_NOTRACK flag, it will never return -memory that can take page faults because of kmemcheck. - -If a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still -request memory with the __GFP_NOTRACK or __GFP_NOTRACK_FALSE_POSITIVE flags. -This does not prevent the page faults from occurring, however, but marks the -object in question as being initialized so that no warnings will ever be -produced for this object. - -Currently, the SLAB and SLUB allocators are supported by kmemcheck. diff --git a/Documentation/ko_KR/memory-barriers.txt b/Documentation/ko_KR/memory-barriers.txt new file mode 100644 index 000000000000..34d3d380893d --- /dev/null +++ b/Documentation/ko_KR/memory-barriers.txt @@ -0,0 +1,3135 @@ +NOTE: +This is a version of Documentation/memory-barriers.txt translated into Korean. +This document is maintained by SeongJae Park . +If you find any difference between this document and the original file or +a problem with the translation, please contact the maintainer of this file. + +Please also note that the purpose of this file is to be easier to +read for non English (read: Korean) speakers and is not intended as +a fork.

+ a[1] = x; + + x 의 예전 값이 a[1] 에, 새 값이 a[0] 에 있게 할 수 있다는 뜻입니다. + 컴파일러와 CPU가 이런 일을 못하게 하려면 다음과 같이 해야 합니다: + + a[0] = READ_ONCE(x); + a[1] = READ_ONCE(x); + + 즉, READ_ONCE() 와 WRITE_ONCE() 는 여러 CPU 에서 하나의 변수에 가해지는 + 액세스들에 캐시 일관성을 제공합니다. + + (*) 컴파일러는 같은 변수에 대한 연속적인 로드들을 병합할 수 있습니다. 그런 + 병합 작업으로 컴파일러는 다음의 코드를: + + while (tmp = a) + do_something_with(tmp); + + 다음과 같이, 싱글 쓰레드 코드에서는 말이 되지만 개발자의 의도와 전혀 맞지 + 않는 방향으로 "최적화" 할 수 있습니다: + + if (tmp = a) + for (;;) + do_something_with(tmp); + + 컴파일러가 이런 짓을 하지 못하게 하려면 READ_ONCE() 를 사용하세요: + + while (tmp = READ_ONCE(a)) + do_something_with(tmp); + + (*) 예컨대 레지스터 사용량이 많아 컴파일러가 모든 데이터를 레지스터에 담을 수 + 없는 경우, 컴파일러는 변수를 다시 로드할 수 있습니다. 따라서 컴파일러는 + 앞의 예에서 변수 'tmp' 사용을 최적화로 없애버릴 수 있습니다: + + while (tmp = a) + do_something_with(tmp); + + 이 코드는 다음과 같이 싱글 쓰레드에서는 완벽하지만 동시성이 존재하는 + 경우엔 치명적인 코드로 바뀔 수 있습니다: + + while (a) + do_something_with(a); + + 예를 들어, 최적화된 이 코드는 변수 a 가 다른 CPU 에 의해 "while" 문과 + do_something_with() 호출 사이에 바뀌어 do_something_with() 에 0을 넘길 + 수도 있습니다. + + 이번에도, 컴파일러가 그런 짓을 하는걸 막기 위해 READ_ONCE() 를 사용하세요: + + while (tmp = READ_ONCE(a)) + do_something_with(tmp); + + 레지스터가 부족한 상황을 겪는 경우, 컴파일러는 tmp 를 스택에 저장해둘 수도 + 있습니다. 컴파일러가 변수를 다시 읽어들이는건 이렇게 저장해두고 후에 다시 + 읽어들이는데 드는 오버헤드 때문입니다. 그렇게 하는게 싱글 쓰레드 + 코드에서는 안전하므로, 안전하지 않은 경우에는 컴파일러에게 직접 알려줘야 + 합니다. + + (*) 컴파일러는 ê·¸ 값이 무엇일지 알고 있다면 로드를 아예 안할 수도 있습니다. + 예를 들어, 다음의 코드는 변수 'a' 의 값이 항상 0임을 증명할 수 있다면: + + while (tmp = a) + do_something_with(tmp); + + 이렇게 최적화 되어버릴 수 있습니다: + + do { } while (0); + + 이 변환은 싱글 쓰레드 코드에서는 도움이 되는데 로드와 브랜치를 제거했기 + 때문입니다. 문제는 컴파일러가 'a' 의 값을 업데이트 하는건 현재의 CPU 하나 + 뿐이라는 가정 위에서 증명을 했다는데 있습니다. 만약 변수 'a' 가 공유되어 + 있다면, 컴파일러의 증명은 틀린 것이 될겁니다. 컴파일러는 ê·¸ 자신이 + 생각하는 것만큼 많은 것을 알고 있지 못함을 컴파일러에게 알리기 위해 + READ_ONCE() 를 사용하세요: + + while (tmp = READ_ONCE(a)) + do_something_with(tmp);

+ WRITE_ONCE(*B, b); + c = READ_ONCE(*C); + d = READ_ONCE(*D); + WRITE_ONCE(*E, e); + +CPU 는 다음 인스트럭션을 처리하기 전에 현재의 인스트럭션을 위한 메모리 +오퍼레이션을 완료할 것이라 생각하고, 따라서 시스템 외부에서 관찰하기에도 정해진 +순서대로 오퍼레이션이 수행될 것으로 예상합니다: + + LOAD *A, STORE *B, LOAD *C, LOAD *D, STORE *E. + + +당연하지만, 실제로는 훨씬 엉망입니다. 많은 CPU 와 컴파일러에서 앞의 가정은 +성립하지 못하는데 ê·¸ 이유는 다음과 같습니다: + + (*) 로드 오퍼레이션들은 실행을 계속 해나가기 위해 곧바로 완료될 필요가 있는 + 경우가 많은 반면, 스토어 오퍼레이션들은 종종 별다른 문제 없이 유예될 수 + 있습니다; + + (*) 로드 오퍼레이션들은 예측적으로 수행될 수 있으며, 필요없는 로드였다고 + 증명된 예측적 로드의 결과는 버려집니다; + + (*) 로드 오퍼레이션들은 예측적으로 수행될 수 있으므로, 예상된 이벤트의 + 시퀀스와 다른 시간에 로드가 이뤄질 수 있습니다; + + (*) 메모리 액세스 순서는 CPU 버스와 캐시를 좀 더 잘 사용할 수 있도록 재배치 + 될 수 있습니다; + + (*) 로드와 스토어는 인접한 위치에의 액세스들을 일괄적으로 처리할 수 있는 + 메모리나 I/O 하드웨어 (메모리와 PCI 디바이스 둘 다 이게 가능할 수 + 있습니다) 에 대해 요청되는 경우, 개별 오퍼레이션을 위한 트랜잭션 설정 + 비용을 아끼기 위해 조합되어 실행될 수 있습니다; 그리고 + + (*) 해당 CPU 의 데이터 캐시가 순서에 영향을 끼칠 수도 있고, 캐시 일관성 + 메커니즘이 - 스토어가 실제로 캐시에 도달한다면 - 이 문제를 완화시킬 수는 + 있지만 이 일관성 관리가 다른 CPU 들에도 같은 순서로 전달된다는 보장은 + 없습니다. + +따라서, 앞의 코드에 대해 다른 CPU 가 보는 결과는 다음과 같을 수 있습니다: + + LOAD *A, ..., LOAD {*C,*D}, STORE *E, STORE *B + + ("LOAD {*C,*D}" 는 조합된 로드입니다) + + +하지만, CPU 는 스스로는 일관적일 것을 보장합니다: CPU _자신_ 의 액세스들은 +자신에게는 메모리 배리어가 없음에도 불구하고 정확히 순서 세워진 것으로 보여질 +것입니다. 예를 들어 다음의 코드가 주어졌다면: + + U = READ_ONCE(*A); + WRITE_ONCE(*A, V); + WRITE_ONCE(*A, W); + X = READ_ONCE(*A); + WRITE_ONCE(*A, Y); + Z = READ_ONCE(*A); + +그리고 외부의 영향에 의한 간섭이 없다고 가정하면, 최종 결과는 다음과 같이 +나타날 것이라고 예상될 수 있습니다: + + U == *A 의 최초 값 + X == W + Z == Y + *A == Y + +앞의 코드는 CPU 가 다음의 메모리 액세스 시퀀스를 만들도록 할겁니다: + + U=LOAD *A, STORE *A=V, STORE *A=W, X=LOAD *A, STORE *A=Y, Z=LOAD *A + +하지만, 별다른 개입이 없고 프로그램의 시야에 이 세상이 여전히 일관적이라고 +보인다는 보장만 지켜진다면 이 시퀀스는 어떤 조합으로든 재구성될 수 있으며, 각 +액세스들은 합쳐지거나 버려질 수 있습니다. 일부 아키텍쳐에서 CPU 는 같은 위치에 +대한 연속적인 로드 오퍼레이션들을 재배치 할 수 있기 때문에 앞의 예에서의 +READ_ONCE() 와 WRITE_ONCE() 는 반드시 존재해야 함을 알아두세요. 그런 종류의 +아키텍쳐에서 READ_ONCE() 와 WRITE_ONCE() 는 이 문제를 막기 위해 필요한 일을 +뭐가 됐든지 하게 되는데, 예를 들어 Itanium 에서는 READ_ONCE() 와 WRITE_ONCE() +가 사용하는 volatile 캐스팅은 GCC 가 그런 재배치를 방지하는 특수 인스트럭션인 +ld.acq 와 stl.rel 인스트럭션을 각각 만들어 내도록 합니다. + +컴파일러 역시 이 시퀀스의 액세스들을 CPU 가 보기도 전에 합치거나 버리거나 뒤로 +미뤄버릴 수 있습니다. + +예를 들어: + + *A = V; + *A = W; + +는 다음과 같이 변형될 수 있습니다: + + *A = W; + +따라서, 쓰기 배리어나 WRITE_ONCE() 가 없다면 *A 로의 V 값의 저장의 효과는 +사라진다고 가정될 수 있습니다. 비슷하게: + + *A = Y; + Z = *A; + +는, 메모리 배리어나 READ_ONCE() 와 WRITE_ONCE() 없이는 다음과 같이 변형될 수 +있습니다: + + *A = Y; + Z = Y; + +그리고 이 LOAD 오퍼레이션은 CPU 바깥에는 아예 보이지 않습니다. + + +그리고, ALPHA 가 있다 +--------------------- + +DEC Alpha CPU 는 가장 완화된 메모리 순서의 CPU 중 하나입니다. 뿐만 아니라, +Alpha CPU 의 일부 버전은 분할된 데이터 캐시를 가지고 있어서, 의미적으로 +관계되어 있는 두개의 캐시 라인이 서로 다른 시간에 업데이트 되는게 가능합니다. +이게 데이터 의존성 배리어가 정말 필요해지는 부분인데, 데이터 의존성 배리어는 +메모리 일관성 시스템과 함께 두개의 캐시를 동기화 시켜서, 포인터 변경과 새로운 +데이터의 발견을 올바른 순서로 일어나게 하기 때문입니다. + +리눅스 커널의 메모리 배리어 모델은 Alpha 에 기초해서 정의되었습니다. + +위의 "캐시 일관성" 서브섹션을 참고하세요. + + +가상 머신 게스트 +---------------- + +가상 머신에서 동작하는 게스트들은 게스트 자체ëŠ” SMP 지원 없이 컴파일 되었다 +해도 SMP 영향을 받을 수 있습니다. 이건 UP 커널을 사용하면서 SMP 호스트와 +결부되어 발생하는 부작용입니다. 이 경우에는 mandatory 배리어를 사용해서 문제를 +해결할 수 있겠지만 그런 해결은 대부분의 경우 최적의 해결책이 아닙니다. + +이 문제를 완벽하게 해결하기 위해, 로우 레벨의 virt_mb() 등의 매크로를 사용할 수 +있습니다. 이것들은 SMP 가 활성화 되어 있다면 smp_mb() 등과 동일한 효과를 +갖습니다만, SMP 와 SMP 아닌 시스템 모두에 대해 동일한 코드를 만들어냅니다. +예를 들어, 가상 머신 게스트들은 (SMP 일 수 있는) 호스트와 동기화를 할 때에는 +smp_mb() 가 아니라 virt_mb() 를 사용해야 합니다. + +이것들은 smp_mb() 류의 것들과 모든 부분에서 동일하며, 특히, MMIO 의 영향에 +대해서는 간여하지 않습니다: MMIO 의 영향을 제어하려면, mandatory 배리어를 +사용하시기 바랍니다. + + +======= +사용 예 +======= + +순환식 버퍼 +----------- + +메모리 배리어는 순환식 버퍼를 생성자(producer)와 소비자(consumer) 사이의 +동기화에 락을 사용하지 않고 구현하는데에 사용될 수 있습니다. 더 자세한 내용을 +위해선 다음을 참고하세요: + + Documentation/circular-buffers.txt + + +========= +참고 문헌 +========= + +Alpha AXP Architecture Reference Manual, Second Edition (Sites & Witek, +Digital Press) + Chapter 5.2: Physical Address Space Characteristics + Chapter 5.4: Caches and Write Buffers + Chapter 5.5: Data Sharing + Chapter 5.6: Read/Write Ordering + +AMD64 Architecture Programmer's Manual Volume 2: System Programming + Chapter 7.1: Memory-Access Ordering + Chapter 7.4: Buffering and Combining Memory Writes + +IA-32 Intel Architecture Software Developer's Manual, Volume 3: +System Programming Guide + Chapter 7.1: Locked Atomic Operations + Chapter 7.2: Memory Ordering + Chapter 7.4: Serializing Instructions + +The SPARC Architecture Manual, Version 9 + Chapter 8: Memory Models + Appendix D: Formal Specification of the Memory Models + Appendix J: Programming with the Memory Models + +UltraSPARC Programmer Reference Manual + Chapter 5: Memory Accesses and Cacheability + Chapter 15: Sparc-V9 Memory Models + +UltraSPARC III Cu User's Manual + Chapter 9: Memory Models + +UltraSPARC IIIi Processor User's Manual + Chapter 8: Memory Models + +UltraSPARC Architecture 2005 + Chapter 9: Memory + Appendix D: Formal Specifications of the Memory Models + +UltraSPARC T1 Supplement to the UltraSPARC Architecture 2005 + Chapter 8: Memory Models + Appendix F: Caches and Cache Coherency + +Solaris Internals, Core Kernel Architecture, p63-68: + Chapter 3.3: Hardware Considerations for Locks and + Synchronization + +Unix Systems for Modern Architectures, Symmetric Multiprocessing and Caching +for Kernel Programmers: + Chapter 13: Other Memory Models + +Intel Itanium Architecture Software Developer's Manual: Volume 1: + Section 2.6: Speculation + Section 4.4: Memory Access diff --git a/Documentation/kprobes.txt b/Documentation/kprobes.txt index 1f9b3e2b98ae..1f6d45abfe42 100644 --- a/Documentation/kprobes.txt +++ b/Documentation/kprobes.txt @@ -103,6 +103,16 @@ Note that the probed function's args may be passed on the stack or in registers.

This offset is + followed by a 4-byte value indicating size of the pointer array. + All numbers in the second plane are also in big endian order. + Remaining data in the second plane is undefined. The information + in the second plane allows to easily find location of the pointer + array, which can be different for each frame. The size of the + pointer array is constant for given UYVY image height. + + In order to extract UYVY and JPEG frames an application can + initially set a data pointer to the start of first plane and then + add an offset from the first entry of the pointers table. Such a + pointer indicates start of an UYVY image pixel line. Whole UYVY + line can be copied to a separate buffer. These steps should be + repeated for each line, i.e. the number of entries in the pointer + array. Anything what's in between the UYVY lines is JPEG data and + should be concatenated to form the JPEG stream. + + + +.. tabularcolumns:: |p{6.6cm}|p{2.2cm}|p{8.7cm}| .. _format-flags: @@ -346,15 +246,10 @@ please make a proposal on the linux-media mailing list. :stub-columns: 0 :widths: 3 1 4 - - - .. row 1 - - - ``V4L2_PIX_FMT_FLAG_PREMUL_ALPHA`` - - - 0x00000001 - - - The color values are premultiplied by the alpha channel value.

Common values are 8, 10 and - 12. - -- The compression (optional). If the pixel components are ALAW- or - DPCM-compressed, a mention of the compression scheme and the number - of bits per compressed pixel component. - -- The number of bus samples per pixel. Pixels that are wider than the - bus width must be transferred in multiple samples. Common values are - 1 and 2. - -- The bus width. - -- For formats where the total number of bits per pixel is smaller than - the number of bus samples per pixel times the bus width, a padding - value stating if the bytes are padded in their most high order bits - (PADHI) or low order bits (PADLO). - -- For formats where the number of bus samples per pixel is larger than - 1, an endianness value stating if the pixel is transferred MSB first - (BE) or LSB first (LE). - -For instance, a format with uncompressed 10-bit Bayer components -arranged in a red, green, green, blue pattern transferred as 2 8-bit -samples per pixel with the least significant bits transferred first will -be named ``MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE``. - - -.. _bayer-patterns: - -.. figure:: subdev-formats_files/bayer.* - :alt: bayer.png - :align: center - - **Figure 4.8 Bayer Patterns** - - - -The following table lists existing packed Bayer formats.

-Those data formats transfer pixel data as (possibly downsampled) Y, U -and V components. Some formats include dummy bits in some of their -samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) -formats. One cannot rely on the values of these dummy bits as those are -undefined. - -The format code is made of the following information. - -- The Y, U and V components order code, as transferred on the bus. - Possible values are YUYV, UYVY, YVYU and VYUY for formats with no - dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC - formats. - -- The number of bits per pixel component. All components are - transferred on the same number of bits. Common values are 8, 10 and - 12. - -- The number of bus samples per pixel. Pixels that are wider than the - bus width must be transferred in multiple samples. Common values are - 1, 1.5 (encoded as 1_5) and 2. - -- The bus width. When the bus width is larger than the number of bits - per pixel component, several components are packed in a single bus - sample. The components are ordered as specified by the order code, - with components on the left of the code transferred in the high order - bits. Common values are 8 and 16. - -For instance, a format where pixels are encoded as 8-bit YUV values -downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in -the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``. - -:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and -describes the organization of each pixel data in each sample. When a -format pattern is split across multiple samples each of the samples in -the pattern is described. - -The role of each bit transferred over the bus is identified by one of -the following codes. - -- y\ :sub:`x` for luma component bit number x - -- u\ :sub:`x` for blue chroma component bit number x - -- v\ :sub:`x` for red chroma component bit number x - -- a\ :sub:`x` for alpha component bit number x - -- - for non-available bits (for positions higher than the bus width) - -- d for dummy bits - - -.. _v4l2-mbus-pixelcode-yuv8: - -.. flat-table:: YUV Formats - :header-rows: 2 - :stub-columns: 0 - - -

This should not be confused with the V4L2 pixel formats +that describe, using four character codes, image formats as stored in +memory. - - u\ :sub:`1` +While there is a relationship between image formats on busses and image +formats in memory (a raw Bayer image won't be magically converted to +JPEG just by storing it to memory), there is no one-to-one +correspondance between them. - - u\ :sub:`0` - - .. _MEDIA-BUS-FMT-YUV10-1X30: +Packed RGB Formats +^^^^^^^^^^^^^^^^^^ - - MEDIA_BUS_FMT_YUV10_1X30 +Those formats transfer pixel data as red, green and blue components. The +format code is made of the following information. - - 0x2016 +- The red, green and blue components order code, as encoded in a pixel + sample. Possible values are RGB and BGR. - - - - - +- The number of bits per component, for each component. The values can + be different for all components. Common values are 555 and 565. - - - +- The number of bus samples per pixel. Pixels that are wider than the + bus width must be transferred in multiple samples. Common values are + 1 and 2. - - y\ :sub:`9` +- The bus width. - - y\ :sub:`8` +- For formats where the total number of bits per pixel is smaller than + the number of bus samples per pixel times the bus width, a padding + value stating if the bytes are padded in their most high order bits + (PADHI) or low order bits (PADLO). A "C" prefix is used for + component-wise padding in the most high order bits (CPADHI) or low + order bits (CPADLO) of each separate component. - - y\ :sub:`7` +- For formats where the number of bus samples per pixel is larger than + 1, an endianness value stating if the pixel is transferred MSB first + (BE) or LSB first (LE). - - y\ :sub:`6` +For instance, a format where pixels are encoded as 5-bits red, 5-bits +green and 5-bit blue values padded on the high bit, transferred as 2 +8-bit samples per pixel with the most significant bits (padding, red and +half of the green value) transferred first will be named +``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``. - - y\ :sub:`5` +The following tables list existing packed RGB formats. - - y\ :sub:`4` +..

- y\ :sub:`4` - - y\ :sub:`3` +Packed YUV Formats +^^^^^^^^^^^^^^^^^^ - - y\ :sub:`2` +Those data formats transfer pixel data as (possibly downsampled) Y, U +and V components. Some formats include dummy bits in some of their +samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) +formats. One cannot rely on the values of these dummy bits as those are +undefined. - - y\ :sub:`1` +The format code is made of the following information. - - y\ :sub:`0` +- The Y, U and V components order code, as transferred on the bus. + Possible values are YUYV, UYVY, YVYU and VYUY for formats with no + dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC + formats. - - u\ :sub:`7` +- The number of bits per pixel component. All components are + transferred on the same number of bits. Common values are 8, 10 and + 12. - - u\ :sub:`6` +- The number of bus samples per pixel. Pixels that are wider than the + bus width must be transferred in multiple samples. Common values are + 1, 1.5 (encoded as 1_5) and 2. - - u\ :sub:`5` +- The bus width. When the bus width is larger than the number of bits + per pixel component, several components are packed in a single bus + sample. The components are ordered as specified by the order code, + with components on the left of the code transferred in the high order + bits. Common values are 8 and 16. - - u\ :sub:`4` +For instance, a format where pixels are encoded as 8-bit YUV values +downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in +the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``. - - u\ :sub:`3` +:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and +describes the organization of each pixel data in each sample. When a +format pattern is split across multiple samples each of the samples in +the pattern is described. - - u\ :sub:`2` +The role of each bit transferred over the bus is identified by one of +the following codes. - - u\ :sub:`1` +- y\ :sub:`x` for luma component bit number x - - u\ :sub:`0` +- u\ :sub:`x` for blue chroma component bit number x - - v\ :sub:`7` +- v\ :sub:`x` for red chroma component bit number x - - v\ :sub:`6` +- a\ :sub:`x` for alpha component bit number x - - v\ :sub:`5` +- for non-available bits (for positions higher than the bus width) - - v\ :sub:`4` +- d for dummy bits - - v\ :sub:`3` +..

Most of the management operations are +framed in a generic Get/Set feature command. + +The following admin queue commands are supported: +- Create I/O submission queue +- Create I/O completion queue +- Destroy I/O submission queue +- Destroy I/O completion queue +- Get feature +- Set feature +- Configure AENQ +- Get statistics + +Refer to ena_admin_defs.h for the list of supported Get/Set Feature +properties. + +The Asynchronous Event Notification Queue (AENQ) is a uni-directional +queue used by the ENA device to send to the driver events that cannot +be reported using ACQ. AENQ events are subdivided into groups. Each +group may have multiple syndromes, as shown below + +The events are: + Group Syndrome + Link state change - X - + Fatal error - X - + Notification Suspend traffic + Notification Resume traffic + Keep-Alive - X - + +ACQ and AENQ share the same MSI-X vector. + +Keep-Alive is a special mechanism that allows monitoring of the +device's health. The driver maintains a watchdog (WD) handler which, +if fired, logs the current state and statistics then resets and +restarts the ENA device and driver. A Keep-Alive event is delivered by +the device every second. The driver re-arms the WD upon reception of a +Keep-Alive event. A missed Keep-Alive event causes the WD handler to +fire. + +Data Path Interface: +==================== +I/O operations are based on Tx and Rx Submission Queues (Tx SQ and Rx +SQ correspondingly). Each SQ has a completion queue (CQ) associated +with it. + +The SQs and CQs are implemented as descriptor rings in contiguous +physical memory. + +The ENA driver supports two Queue Operation modes for Tx SQs: +- Regular mode + * In this mode the Tx SQs reside in the host's memory. The ENA + device fetches the ENA Tx descriptors and packet data from host + memory. +- Low Latency Queue (LLQ) mode or "push-mode". + * In this mode the driver pushes the transmit descriptors and the + first 128 bytes of the packet directly to the ENA device memory + space. The rest of the packet payload is fetched by the + device. For this operation mode, the driver uses a dedicated PCI + device memory BAR, which is mapped with write-combine capability. + +The Rx SQs support only the regular mode. + +Note: Not all ENA devices support LLQ, and this feature is negotiated + with the device upon initialization. If the ENA device does not + support LLQ mode, the driver falls back to the regular mode. + +The driver supports multi-queue for both Tx and Rx. This has various +benefits: +- Reduced CPU/thread/process contention on a given Ethernet interface. +- Cache miss rate on completion is reduced, particularly for data + cache lines that hold the sk_buff structures. +- Increased process-level parallelism when handling received packets. +- Increased data cache hit rate, by steering kernel processing of + packets to the CPU, where the application thread consuming the + packet is running. +- In hardware interrupt re-direction. + +Interrupt Modes: +================ +The driver assigns a single MSI-X vector per queue pair (for both Tx +and Rx directions). The driver assigns an additional dedicated MSI-X vector +for management (for ACQ and AENQ). + +Management interrupt registration is performed when the Linux kernel +probes the adapter, and it is de-registered when the adapter is +removed. I/O queue interrupt registration is performed when the Linux +interface of the adapter is opened, and it is de-registered when the +interface is closed. + +The management interrupt is named: + ena-mgmnt@pci: +and for each queue pair, an interrupt is named: + -Tx-Rx- + +The ENA device operates in auto-mask and auto-clear interrupt +modes. That is, once MSI-X is delivered to the host, its Cause bit is +automatically cleared and the interrupt is masked. The interrupt is +unmasked by the driver after NAPI processing is complete. + +Interrupt Moderation: +===================== +ENA driver and device can operate in conventional or adaptive interrupt +moderation mode. + +In conventional mode the driver instructs device to postpone interrupt +posting according to static interrupt delay value. The interrupt delay +value can be configured through ethtool(8). The following ethtool +parameters are supported by the driver: tx-usecs, rx-usecs + +In adaptive interrupt moderation mode the interrupt delay value is +updated by the driver dynamically and adjusted every NAPI cycle +according to the traffic nature. + +By default ENA driver applies adaptive coalescing on Rx traffic and +conventional coalescing on Tx traffic. + +Adaptive coalescing can be switched on/off through ethtool(8) +adaptive_rx on|off parameter. + +The driver chooses interrupt delay value according to the number of +bytes and packets received between interrupt unmasking and interrupt +posting. The driver uses interrupt delay table that subdivides the +range of received bytes/packets into 5 levels and assigns interrupt +delay value to each level. + +The user can enable/disable adaptive moderation, modify the interrupt +delay table and restore its default values through sysfs. + +The rx_copybreak is initialized by default to ENA_DEFAULT_RX_COPYBREAK +and can be configured by the ETHTOOL_STUNABLE command of the +SIOCETHTOOL ioctl. + +SKB: +The driver-allocated SKB for frames received from Rx handling using +NAPI context. The allocation method depends on the size of the packet. +If the frame length is larger than rx_copybreak, napi_get_frags() +is used, otherwise netdev_alloc_skb_ip_align() is used, the buffer +content is copied (by CPU) to the SKB, and the buffer is recycled. + +Statistics: +=========== +The user can obtain ENA device and driver statistics using ethtool. +The driver can collect regular or extended statistics (including +per-queue stats) from the device. + +In addition the driver logs the stats to syslog upon device reset. + +MTU: +==== +The driver supports an arbitrarily large MTU with a maximum that is +negotiated with the device. The driver configures MTU using the +SetFeature command (ENA_ADMIN_MTU property). The user can change MTU +via ip(8) and similar legacy tools. + +Stateless Offloads: +=================== +The ENA driver supports: +- TSO over IPv4/IPv6 +- TSO with ECN +- IPv4 header checksum offload +- TCP/UDP over IPv4/IPv6 checksum offloads + +RSS: +==== +- The ENA device supports RSS that allows flexible Rx traffic + steering. +- Toeplitz and CRC32 hash functions are supported. +- Different combinations of L2/L3/L4 fields can be configured as + inputs for hash functions. +- The driver configures RSS settings using the AQ SetFeature command + (ENA_ADMIN_RSS_HASH_FUNCTION, ENA_ADMIN_RSS_HASH_INPUT and + ENA_ADMIN_RSS_REDIRECTION_TABLE_CONFIG properties). +- If the NETIF_F_RXHASH flag is set, the 32-bit result of the hash + function delivered in the Rx CQ descriptor is set in the received + SKB. +- The user can provide a hash key, hash function, and configure the + indirection table through ethtool(8). + +DATA PATH: +========== +Tx: +--- +end_start_xmit() is called by the stack.

The code was developed +originally to detect SMIs (System Management Interrupts) on x86 systems, +however there is nothing x86 specific about this patchset. It was +originally written for use by the "RT" patch since the Real Time +kernel is highly latency sensitive. + +SMIs are not serviced by the Linux kernel, which means that it does not +even know that they are occuring. SMIs are instead set up by BIOS code +and are serviced by BIOS code, usually for "critical" events such as +management of thermal sensors and fans. Sometimes though, SMIs are used for +other tasks and those tasks can spend an inordinate amount of time in the +handler (sometimes measured in milliseconds). Obviously this is a problem if +you are trying to keep event service latencies down in the microsecond range. + +The hardware latency detector works by hogging one of the cpus for configurable +amounts of time (with interrupts disabled), polling the CPU Time Stamp Counter +for some period, then looking for gaps in the TSC data. Any gap indicates a +time when the polling was interrupted and since the interrupts are disabled, +the only thing that could do that would be an SMI or other hardware hiccup +(or an NMI, but those can be tracked). + +Note that the hwlat detector should *NEVER* be used in a production environment. +It is intended to be run manually to determine if the hardware platform has a +problem with long system firmware service routines. + +Usage: +------ + +Write the ASCII text "hwlat" into the current_tracer file of the tracing system +(mounted at /sys/kernel/tracing or /sys/kernel/tracing). It is possible to +redefine the threshold in microseconds (us) above which latency spikes will +be taken into account. + +Example: + + # echo hwlat > /sys/kernel/tracing/current_tracer + # echo 100 > /sys/kernel/tracing/tracing_thresh + +The /sys/kernel/tracing/hwlat_detector interface contains the following files: + +width - time period to sample with CPUs held (usecs) + must be less than the total window size (enforced) +window - total period of sampling, width being inside (usecs) + +By default the width is set to 500,000 and window to 1,000,000, meaning that +for every 1,000,000 usecs (1s) the hwlat detector will spin for 500,000 usecs +(0.5s). If tracing_thresh contains zero when hwlat tracer is enabled, it will +change to a default of 10 usecs. If any latencies that exceed the threshold is +observed then the data will be written to the tracing ring buffer. + +The minimum sleep time between periods is 1 millisecond. Even if width +is less than 1 millisecond apart from window, to allow the system to not +be totally starved. + +If tracing_thresh was zero when hwlat detector was started, it will be set +back to zero if another tracer is loaded. Note, the last value in +tracing_thresh that hwlat detector had will be saved and this value will +be restored in tracing_thresh if it is still zero when hwlat detector is +started again. + +The following tracing directory files are used by the hwlat_detector: + +in /sys/kernel/tracing: + + tracing_threshold - minimum latency value to be considered (usecs) + tracing_max_latency - maximum hardware latency actually observed (usecs) + tracing_cpumask - the CPUs to move the hwlat thread across + hwlat_detector/width - specified amount of time to spin within window (usecs) + hwlat_detector/window - amount of time between (width) runs (usecs) + +The hwlat detector's kernel thread will migrate across each CPU specified in +tracing_cpumask between each window.

A level + triggered interrupt may be pending either because the level input is held + high by a device, or because of a guest write to the ISPENDR register.
