- See Documentation/acpi/debug.txt for more information
- about debug layers and levels.
+ The debug_level mask defaults to "info". See
+ Documentation/acpi/debug.txt for more information about
+ debug layers and levels.
+ Enable processor driver info messages:
+ acpi.debug_layer=0x20000000
+ Enable PCI/PCI interrupt routing info messages:
+ acpi.debug_layer=0x400000
Enable AML "Debug" output, i.e., stores to the Debug
object while interpreting AML:
acpi.debug_layer=0xffffffff acpi.debug_level=0x2
- Enable PCI/PCI interrupt routing info messages:
- acpi.debug_layer=0x400000 acpi.debug_level=0x4
Enable all messages related to ACPI hardware:
acpi.debug_layer=0x2 acpi.debug_level=0xffffffff
Possible values are:
isolate - enable device isolation (each device, as far
as possible, will get its own protection
- domain)
+ domain) [default]
+ share - put every device behind one IOMMU into the
+ same protection domain
fullflush - enable flushing of IO/TLB entries when
they are unmapped. Otherwise they are
flushed before they will be reused, which
it is equivalent to "nosmp", which also disables
the IO APIC.
