What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io}
|
||||
Date: July 2010
|
||||
Contact: Thomas Renninger <trenn@suse.de>
|
||||
Description:
|
||||
|
||||
General information like which GPE is assigned to the EC and whether
|
||||
the global lock should get used.
|
||||
Knowing the EC GPE one can watch the amount of HW events related to
|
||||
the EC here (XY -> GPE number from /sys/kernel/debug/ec/*/gpe):
|
||||
/sys/firmware/acpi/interrupts/gpeXY
|
||||
|
||||
The io file is binary and a userspace tool located here:
|
||||
ftp://ftp.suse.com/pub/people/trenn/sources/ec/
|
||||
should get used to read out the 256 Embedded Controller registers
|
||||
or writing to them.
|
||||
|
||||
CAUTION: Do not write to the Embedded Controller if you don't know
|
||||
what you are doing! Rebooting afterwards also is a good idea.
|
||||
This can influence the way your machine is cooled and fans may
|
||||
not get switched on again after you did a wrong write.

EXPERIMENTAL: Embedded controller register dump

|

EXPERIMENTAL: Embedded controller register dump -- /proc/acpi/ibm/ecdump
|
||||
------------------------------------------------------------------------
|
||||
This feature is not included in the thinkpad driver anymore.
|
||||
Instead the EC can be accessed through /sys/kernel/debug/ec with
|
||||
a userspace tool which can be found here:
|
||||
ftp://ftp.suse.com/pub/people/trenn/sources/ec
|
||||
|
||||
This feature is marked EXPERIMENTAL because the implementation
|
||||
directly accesses hardware registers and may not work as expected. USE
|
||||
WITH CAUTION! To use this feature, you need to supply the
|
||||
experimental=1 parameter when loading the module.
|
||||
|
||||
This feature dumps the values of 256 embedded controller
|
||||
registers. Values which have changed since the last time the registers
|
||||
were dumped are marked with a star:

This feature can be used to determine the register holding the fan
|
||||
Use it to determine the register holding the fan
|
||||
speed on some models. To do that, do the following:
|
||||
|
||||
- make sure the battery is fully charged
|
||||
- make sure the fan is running
|
||||
- run 'cat /proc/acpi/ibm/ecdump' several times, once per second or so
|
||||
- use above mentioned tool to read out the EC
|
||||
|
||||
The first step makes sure various charging-related values don't
|
||||
vary. The second ensures that the fan-related values do vary, since
|
||||
the fan speed fluctuates a bit. The third will (hopefully) mark the
|
||||
fan register with a star:

|

|
||||
Another set of values that varies often is the temperature
|
||||
Often fan and temperature values vary between
|
||||
readings. Since temperatures don't change vary fast, you can take
|
||||
several quick dumps to eliminate them.

Be aware that using this interface can confuse your Embedded
|
||||
Controller in a way that a normal reboot is not enough. You then
|
||||
have to power of your system, and remove the laptop battery for
|
||||
some seconds.
|
||||
An Embedded Controller typically is available on laptops and reads
|
||||
sensor values like battery state and temperature.
|
||||
The kernel accesses the EC through ACPI parsed code provided by BIOS
|
||||
tables. This option allows to access the EC directly without ACPI
|
||||
code being involved.
|
||||
Thus this option is a debug option that helps to write ACPI drivers
|
||||
and can be used to identify ACPI code or EC firmware bugs.

The restricted access region control registers

This driver allows other kernel drivers access to the
|
||||
contents of the restricted access region control registers.
|
||||
|
||||
The restricted access region control registers
|
||||
(rar_registers) are used to pass address and
|
||||
locking information on restricted access regions
|
||||
to other drivers that use restricted access regions.
|
||||
|
||||
The restricted access regions are regions of memory
|
||||
on the Intel MID Platform that are not accessible to
|
||||
the x86 processor, but are accessible to dedicated
|
||||
processors on board peripheral devices.
|
||||
|
||||
The purpose of the restricted access regions is to
|
||||
protect sensitive data from compromise by unauthorized
|
||||
programs running on the x86 processor.
