-Generic ARM big LITTLE cpufreq driver's DT glue
------------------------------------------------
-
-This is DT specific glue layer for generic cpufreq driver for big LITTLE
-systems.
-
-Both required and optional properties listed below must be defined
-under node /cpus/cpu@x. Where x is the first cpu inside a cluster.
-
-FIXME: Cpus should boot in the order specified in DT and all cpus for a cluster
-must be present contiguously. Generic DT driver will check only node 'x' for
-cpu:x.
-
-Required properties:
-- operating-points: Refer to Documentation/devicetree/bindings/opp/opp.txt

-Optional properties:
-- clock-latency: Specify the possible maximum transition latency for clock,
- in unit of nanoseconds.

+drm/amd/display - Display Core (DC)
+===================================
+
+*placeholder - general description of supported platforms, what dc is, etc.*
+
+Because it is partially shared with other operating systems, the Display Core
+Driver is divided in two pieces.
+
+1. **Display Core (DC)** contains the OS-agnostic components. Things like
+ hardware programming and resource management are handled here.
+2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
+ amdgpu base driver and DRM are implemented here.
+
+It doesn't help that the entire package is frequently referred to as DC. But
+with the context in mind, it should be clear.
+
+When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
+supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
+Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
+
+To determine if DC is loaded, search dmesg for the following entry:
+
+``Display Core initialized with <version number here>``

+
+Description
+-----------
+
+i2c-nvidia-gpu is a driver for I2C controller included in NVIDIA Turing
+and later GPUs and it is used to communicate with Type-C controller on GPUs.
+
+If your 'lspci -v' listing shows something like the following,
+
+01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
+
+then this driver should support the I2C controller of your GPU.
Query the address space, and return true if it is completely
unevictable.
-These are currently used in two places in the kernel:
+These are currently used in three places in the kernel:
(1) By ramfs to mark the address spaces of its inodes when they are created,
and this mark remains for the life of the inode.
swapped out; the application must touch the pages manually if it wants to
ensure they're in memory.
+ (3) By the i915 driver to mark pinned address space until it's unpinned. The
+ amount of unevictable memory marked by i915 driver is roughly the bounded
+ object size in debugfs/dri/0/i915_gem_objects.

+/**
+ * DOC: overview
+ *
+ * DM provides another layer of IRQ management on top of what the base driver
+ * already provides. This is something that could be cleaned up, and is a
+ * future TODO item.
+ *
+ * The base driver provides IRQ source registration with DRM, handler
+ * registration into the base driver's IRQ table, and a handler callback
+ * amdgpu_irq_handler(), with which DRM calls on interrupts. This generic
+ * handler looks up the IRQ table, and calls the respective
+ * &amdgpu_irq_src_funcs.process hookups.
+ *
+ * What DM provides on top are two IRQ tables specifically for top-half and
+ * bottom-half IRQ handling, with the bottom-half implementing workqueues:
+ *
+ * - &amdgpu_display_manager.irq_handler_list_high_tab
+ * - &amdgpu_display_manager.irq_handler_list_low_tab
+ *
+ * They override the base driver's IRQ table, and the effect can be seen
+ * in the hooks that DM provides for &amdgpu_irq_src_funcs.process. They
+ * are all set to the DM generic handler amdgpu_dm_irq_handler(), which looks up
+ * DM's IRQ tables. However, in order for base driver to recognize this hook, DM
+ * still needs to register the IRQ with the base driver. See
+ * dce110_register_irq_handlers() and dcn10_register_irq_handlers().
+ *
+ * To expose DC's hardware interrupt toggle to the base driver, DM implements
+ * &amdgpu_irq_src_funcs.set hooks. Base driver calls it through
+ * amdgpu_irq_update() to enable or disable the interrupt.

*
* @get_tile_config: Returns GPU-specific tiling mode information
*
- * @get_cu_info: Retrieves activated cu info

- * completed. This allows multiple map operations (on multiple GPUs)
- * to happen concurrently. Use sync_memory to synchronize with all

- *

- * specified VMID in a user mode context.
- *
- * @get_vm_fault_info: Return information about a recent VM fault on
- * GFXv7 and v8. If multiple VM faults occurred since the last call of

+<h3>Points to note:</h3>
+<ul>
+<li>The top level is a command name (comm)</li>
+<li>The next level is a thread (pid:tid)</li>
+<li>Subsequent levels are functions</li>
+<li>'Count' is the number of calls</li>
+<li>'Time' is the elapsed time until the function returns</li>
+<li>Percentages are relative to the level above</li>
+<li>'Branch Count' is the total number of branches for that function and all functions that it calls
+</ul>
+<h3>Find</h3>
+Ctrl-F displays a Find bar which finds function names by either an exact match or a pattern match.
+The pattern matching symbols are ? for any character and * for zero or more characters.
+<h2 id=allbranches>1.2 All branches</h2>
+The All branches report displays all branches in chronological order.
+Not all data is fetched immediately. More records can be fetched using the Fetch bar provided.
+<h3>Disassembly</h3>
+Open a branch to display disassembly. This only works if:
+<ol>
+<li>The disassembler is available. Currently, only Intel XED is supported - see <a href=#xed>Intel XED Setup</a></li>
+<li>The object code is available. Currently, only the perf build ID cache is searched for object code.
+The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR.
+One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu),
+or alternatively, set environment variable PERF_KCORE to the kcore file name.</li>
+</ol>
+<h4 id=xed>Intel XED Setup</h4>
+To use Intel XED, libxed.so must be present. To build and install libxed.so:
+<pre>
+git clone https://github.com/intelxed/mbuild.git mbuild
+git clone https://github.com/intelxed/xed
+cd xed
+./mfile.py --share
+sudo ./mfile.py --prefix=/usr/local install
+sudo ldconfig
+</pre>
+<h3>Find</h3>
+Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
+Refer to Python documentation for the regular expression syntax.
+All columns are searched, but only currently fetched rows are searched.
+<h2 id=selectedbranches>1.3 Selected branches</h2>
+This is the same as the <a href=#allbranches>All branches</a> report but with the data reduced
+by various selection criteria. A dialog box displays available criteria which are AND'ed together.
+<h3>1.3.1 Time ranges</h3>
+The time ranges hint text shows the total time range. Relative time ranges can also be entered in
+ms, us or ns. Also, negative values are relative to the end of trace. Examples:
+<pre>
+ 81073085947329-81073085958238 From 81073085947329 to 81073085958238
+ 100us-200us From 100us to 200us
+ 10ms- From 10ms to the end
+ -100ns The first 100ns
+ -10ms- The last 10ms
+</pre>
+N.B. Due to the granularity of timestamps, there could be no branches in any given time range.
+<h1 id=tables>2. Tables</h1>
+The Tables menu shows all tables and views in the database. Most tables have an associated view
+which displays the information in a more friendly way. Not all data for large tables is fetched
+immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted,
+but that can be slow for large tables.
+<p>There are also tables of database meta-information.
+For SQLite3 databases, the sqlite_master table is included.
+For PostgreSQL databases, information_schema.tables/views/columns are included.
+<h3>Find</h3>
+Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
+Refer to Python documentation for the regular expression syntax.
+All columns are searched, but only currently fetched rows are searched.
+<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous
+will go to the next/previous result in id order, instead of display order.
