acpi.debug_level= [HW,ACPI]
|
||||
Format: <int>
|
||||
Each bit of the <int> indicates an ACPI debug level,
|
||||
1: enable, 0: disable. It is useful for boot time
|
||||
debugging. After system has booted up, it can be set
|
||||
via /sys/module/acpi/parameters/debug_level.
|
||||
CONFIG_ACPI_DEBUG must be enabled for this to produce any output.
|
||||
Available bits (add the numbers together) to enable different
|
||||
debug output levels of the ACPI subsystem:
|
||||
0x01 error 0x02 warn 0x04 init 0x08 debug object
|
||||
0x10 info 0x20 init names 0x40 parse 0x80 load
|
||||
0x100 dispatch 0x200 execute 0x400 names 0x800 operation region
|
||||
0x1000 bfield 0x2000 tables 0x4000 values 0x8000 objects
|
||||
0x10000 resources 0x20000 user requests 0x40000 package.
|
||||
The number can be in decimal or prefixed with 0x in hex.
|
||||
Warning: Many of these options can produce a lot of
|
||||
output and make your system unusable. Be very careful.
|
||||
which corresponds to the level in an ACPI_DEBUG_PRINT
|
||||
statement. After system has booted up, this mask
|
||||
can be set via /sys/module/acpi/parameters/debug_level.

CONFIG_ACPI_DEBUG must be enabled for this to produce
|

any output. The number can be in decimal or prefixed
|

with 0x in hex. Some of these options produce so much
|

output that the system is unusable.
|

The following global components are defined by the
|

ACPI CA:

0x01 error

0x04 init
|
