1What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io}
2Date: July 2010
3Contact: Thomas Renninger <trenn@suse.de>
4Description:
5
6General information like which GPE is assigned to the EC and whether
7the global lock should get used.
8Knowing the EC GPE one can watch the amount of HW events related to
9the EC here (XY -> GPE number from /sys/kernel/debug/ec/*/gpe):
10/sys/firmware/acpi/interrupts/gpeXY
11
12The io file is binary and a userspace tool located here:
13ftp://ftp.suse.com/pub/people/trenn/sources/ec/
14should get used to read out the 256 Embedded Controller registers
15or writing to them.
16
17CAUTION: Do not write to the Embedded Controller if you don't know
18what you are doing! Rebooting afterwards also is a good idea.
19This can influence the way your machine is cooled and fans may
20not get switched on again after you did a wrong write.

963EXPERIMENTAL: Embedded controller register dump
964-----------------------------------------------

964EXPERIMENTAL: Embedded controller register dump -- /proc/acpi/ibm/ecdump 966This feature is not included in the thinkpad driver anymore.
965------------------------------------------------------------------------ 967Instead the EC can be accessed through /sys/kernel/debug/ec with
966 968a userspace tool which can be found here:
967This feature is marked EXPERIMENTAL because the implementation 969ftp://ftp.suse.com/pub/people/trenn/sources/ec
968directly accesses hardware registers and may not work as expected. USE
969WITH CAUTION! To use this feature, you need to supply the
970experimental=1 parameter when loading the module.
971
972This feature dumps the values of 256 embedded controller
973registers. Values which have changed since the last time the registers
974were dumped are marked with a star:

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

557 This driver allows other kernel drivers access to the

559
560 The restricted access region control registers
561 (rar_registers) are used to pass address and
562 locking information on restricted access regions
563 to other drivers that use restricted access regions.
564
565 The restricted access regions are regions of memory
566 on the Intel MID Platform that are not accessible to
567 the x86 processor, but are accessible to dedicated
568 processors on board peripheral devices.
569
570 The purpose of the restricted access regions is to

24/*
25 * Some Intel Ibex Peak based platforms support so-called "intelligent
26 * power sharing", which allows the CPU and GPU to cooperate to maximize
27 * performance within a given TDP (thermal design point). This driver
28 * performs the coordination between the CPU and GPU, monitors thermal and
29 * power statistics in the platform, and initializes power monitoring
30 * hardware. It also provides a few tunables to control behavior. Its
31 * primary purpose is to safely allow CPU and GPU turbo modes to be enabled
32 * by tracking power and thermal budget; secondarily it can boost turbo
33 * performance by allocating more power or thermal budget to the CPU or GPU
34 * based on available headroom and activity.
35 *
36 * The basic algorithm is driven by a 5s moving average of tempurature. If
37 * thermal headroom is available, the CPU and/or GPU power clamps may be
38 * adjusted upwards. If we hit the thermal ceiling or a thermal trigger,
39 * we scale back the clamp. Aside from trigger events (when we're critically
40 * close or over our TDP) we don't adjust the clamps more than once every
41 * five seconds.
42 *
43 * The thermal device (device 31, function 6) has a set of registers that
44 * are updated by the ME firmware. The ME should also take the clamp values
45 * written to those registers and write them to the CPU, but we currently
46 * bypass that functionality and write the CPU MSR directly.
47 *
48 * UNSUPPORTED:
49 * - dual MCP configs
50 *
51 * TODO:
52 * - handle CPU hotplug
53 * - provide turbo enable/disable api
54 * - make sure we can write turbo enable/disable reg based on MISC_EN

13 ---help---
14 This driver allows other kernel drivers access to the
15 contents of the restricted access region control registers.
16
17 The restricted access region control registers
18 (rar_registers) are used to pass address and
19 locking information on restricted access regions
20 to other drivers that use restricted access regions.
21
22 The restricted access regions are regions of memory
23 on the Intel MID Platform that are not accessible to
24 the x86 processor, but are accessible to dedicated
25 processors on board peripheral devices.
26
27 The purpose of the restricted access regions is to
28 protect sensitive data from compromise by unauthorized
29 programs running on the x86 processor.
