What: /sys/devices/system/cpu/cpu*/cache/index*/cache_disable_X
Date: August 2008
KernelVersion: 2.6.27
Contact: mark.langsdorf@amd.com
Description: These files exist in every cpu's cache index directories.
There are currently 2 cache_disable_# files in each
directory. Reading from these files on a supported
processor will return that cache disable index value
for that processor and node. Writing to one of these
files will cause the specificed cache index to be disabled.
Currently, only AMD Family 10h Processors support cache index
disable, and only for their L3 caches. See the BIOS and
Kernel Developer's Guide at
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/31116-Public-GH-BKDG_3.20_2-4-09.pdf

Description: Discover and adjust the kernel's multi-core scheduler support.
Possible values are:
0 - No power saving load balance (default value)
1 - Fill one thread/core/package first for long running threads
2 - Also bias task wakeups to semi-idle cpu package for power
savings
sched_mc_power_savings is dependent upon SCHED_MC, which is
itself architecture dependent.
sched_smt_power_savings is dependent upon SCHED_SMT, which
is itself architecture dependent.
The two files are independent of each other. It is possible
that one file may be present without the other.

3. A simple implementation
ACPI thermal zone may support multiple trip points like critical/hot/passive/active.
If an ACPI thermal zone supports critical, passive, active[0] and active[1] at the same time,
it may register itself as a thermal_zone_device (thermal_zone1) with 4 trip points in all.
It has one processor and one fan, which are both registered as thermal_cooling_device.
If the processor is listed in _PSL method, and the fan is listed in _AL0 method,
the sys I/F structure will be built like this:

thermal_cooling_device.
If the processor is listed in _PSL method, and the fan is listed in _AL0
method, the sys I/F structure will be built like this:
/sys/class/thermal:
