ACPI Debug Output
The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
output. This document describes how to use this facility.
Compile-time configuration
--------------------------
ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG. If this config
option is turned off, the debug messages are not even built into the
kernel.
Boot- and run-time configuration
--------------------------------
When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
you're interested in. At boot-time, use the acpi.debug_layer and
acpi.debug_level kernel command line options. After boot, you can use the
debug_layer and debug_level files in /sys/module/acpi/parameters/ to control
the debug messages.
debug_layer (component)
-----------------------
The "debug_layer" is a mask that selects components of interest, e.g., a
specific driver or part of the ACPI interpreter. To build the debug_layer
bitmask, look for the "#define _COMPONENT" in an ACPI source file.
You can set the debug_layer mask at boot-time using the acpi.debug_layer
command line argument, and you can change it after boot by writing values
to /sys/module/acpi/parameters/debug_layer.
The possible components are defined in include/acpi/acoutput.h and
include/acpi/acpi_drivers.h. Reading /sys/module/acpi/parameters/debug_layer
shows the supported mask values, currently these:
ACPI_UTILITIES 0x00000001
ACPI_HARDWARE 0x00000002
ACPI_EVENTS 0x00000004

ACPI_VIDEO_COMPONENT 0x10000000
ACPI_PROCESSOR_COMPONENT 0x20000000
debug_level
-----------
The "debug_level" is a mask that selects different types of messages, e.g.,
those related to initialization, method execution, informational messages, etc.
To build debug_level, look at the level specified in an ACPI_DEBUG_PRINT()
statement.
The ACPI interpreter uses several different levels, but the Linux
ACPI core and ACPI drivers generally only use ACPI_LV_INFO.
You can set the debug_level mask at boot-time using the acpi.debug_level
command line argument, and you can change it after boot by writing values
to /sys/module/acpi/parameters/debug_level.
The possible levels are defined in include/acpi/acoutput.h. Reading
/sys/module/acpi/parameters/debug_level shows the supported mask values,
currently these:
ACPI_LV_INIT 0x00000001
ACPI_LV_DEBUG_OBJECT 0x00000002
ACPI_LV_INFO 0x00000004
ACPI_LV_INIT_NAMES 0x00000020

ACPI_LV_FULL_TABLES 0x40000000
ACPI_LV_EVENTS 0x80000000
Examples
--------
For example, drivers/acpi/bus.c contains this:
#define _COMPONENT ACPI_BUS_COMPONENT
...
ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Device insertion detected\n"));
To turn on this message, set the ACPI_BUS_COMPONENT bit in acpi.debug_layer
and the ACPI_LV_INFO bit in acpi.debug_level. (The ACPI_DEBUG_PRINT
statement uses ACPI_DB_INFO, which is macro based on the ACPI_LV_INFO
definition.)
Enable all AML "Debug" output (stores to the Debug object while interpreting
AML) during boot:
acpi.debug_layer=0xffffffff acpi.debug_level=0x2
Enable PCI and PCI interrupt routing debug messages:
acpi.debug_layer=0x400000 acpi.debug_level=0x4
Enable all ACPI hardware-related messages:
acpi.debug_layer=0x2 acpi.debug_level=0xffffffff
Enable all ACPI_DB_INFO messages after boot:
# echo 0x4 > /sys/module/acpi/parameters/debug_level
Show all valid component values:
# cat /sys/module/acpi/parameters/debug_layer

C2 port support
---------------

This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or

but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
Overview
--------
This driver implements the support for Linux of Silicon Labs (Silabs)
C2 Interface used for in-system programming of micro controllers.
By using this driver you can reprogram the in-system flash without EC2
or EC3 debug adapter. This solution is also useful in those systems
where the micro controller is connected via special GPIOs pins.
References
----------
The C2 Interface main references are at (http://www.silabs.com)
Silicon Laboratories site], see:
- AN127: FLASH Programming via the C2 Interface at
http://www.silabs.com/public/documents/tpub_doc/anote/Microcontrollers/Small_Form_Factor/en/an127.pdf, and
- C2 Specification at
http://www.silabs.com/public/documents/tpub_doc/spec/Microcontrollers/en/C2spec.pdf,
however it implements a two wire serial communication protocol (bit
banging) designed to enable in-system programming, debugging, and
boundary-scan testing on low pin-count Silicon Labs devices. Currently
this code supports only flash programming but extensions are easy to
add.
Using the driver
----------------
Once the driver is loaded you can use sysfs support to get C2port's
info or read/write in-system flash.
# ls /sys/class/c2port/c2port0/
access flash_block_size flash_erase rev_id
dev_id flash_blocks_num flash_size subsystem/
flash_access flash_data reset uevent
Initially the C2port access is disabled since you hardware may have
such lines multiplexed with other devices so, to get access to the
C2port, you need the command:
# echo 1 > /sys/class/c2port/c2port0/access
after that you should read the device ID and revision ID of the
connected micro controller:
# cat /sys/class/c2port/c2port0/dev_id
8
# cat /sys/class/c2port/c2port0/rev_id
1
However, for security reasons, the in-system flash access in not
enabled yet, to do so you need the command:
# echo 1 > /sys/class/c2port/c2port0/flash_access
After that you can read the whole flash:
# cat /sys/class/c2port/c2port0/flash_data > image
erase it:
# echo 1 > /sys/class/c2port/c2port0/flash_erase
and write it:
# cat image > /sys/class/c2port/c2port0/flash_data
after writing you have to reset the device to execute the new code:
# echo 1 > /sys/class/c2port/c2port0/reset

This directory contains configuration options for the epoll(7) interface.
max_user_instances
------------------
This is the maximum number of epoll file descriptors that a single user can
have open at a given time. The default value is 128, and should be enough
for normal users.
max_user_watches
----------------
Every epoll file descriptor can store a number of files to be monitored
for event readiness. Each one of these monitored files constitutes a "watch".
This configuration option sets the maximum number of "watches" that are
allowed for each user.
Each "watch" costs roughly 90 bytes on a 32bit kernel, and roughly 160 bytes
on a 64bit one.
The current default value for max_user_watches is the 1/32 of the available
low memory, divided for the "watch" cost in bytes.

Kernel driver adt7462
======================
Supported chips:
* Analog Devices ADT7462
Prefix: 'adt7462'
Addresses scanned: I2C 0x58, 0x5C
Datasheet: Publicly available at the Analog Devices website
Author: Darrick J. Wong
Description
-----------
This driver implements support for the Analog Devices ADT7462 chip family.
This chip is a bit of a beast. It has 8 counters for measuring fan speed. It
can also measure 13 voltages or 4 temperatures, or various combinations of the
two. See the chip documentation for more details about the exact set of
configurations. This driver does not allow one to configure the chip; that is
left to the system designer.
A sophisticated control system for the PWM outputs is designed into the ADT7462
that allows fan speed to be adjusted automatically based on any of the three
temperature sensors. Each PWM output is individually adjustable and
programmable. Once configured, the ADT7462 will adjust the PWM outputs in
response to the measured temperatures without further host intervention. This
feature can also be disabled for manual control of the PWM's.
Each of the measured inputs (voltage, temperature, fan speed) has
corresponding high/low limit values. The ADT7462 will signal an ALARM if
any measured value exceeds either limit.
The ADT7462 samples all inputs continuously. The driver will not read
the registers more often than once every other second. Further,
configuration data is only read once per minute.
Special Features
----------------
The ADT7462 have a 10-bit ADC and can therefore measure temperatures
with 0.25 degC resolution.
The Analog Devices datasheet is very detailed and describes a procedure for
determining an optimal configuration for the automatic PWM control.
The driver will report sensor labels when it is able to determine that
information from the configuration registers.
Configuration Notes
-------------------
Besides standard interfaces driver adds the following:
* PWM Control
* pwm#_auto_point1_pwm and temp#_auto_point1_temp and
* pwm#_auto_point2_pwm and temp#_auto_point2_temp -
point1: Set the pwm speed at a lower temperature bound.
point2: Set the pwm speed at a higher temperature bound.
The ADT7462 will scale the pwm between the lower and higher pwm speed when
the temperature is between the two temperature boundaries. PWM values range
from 0 (off) to 255 (full speed). Fan speed will be set to maximum when the
temperature sensor associated with the PWM control exceeds temp#_max.

Kernel driver lis3lv02d
==================
Supported chips:
* STMicroelectronics LIS3LV02DL and LIS3LV02DQ
Author:
Yan Burman <burman.yan@gmail.com>
Eric Piel <eric.piel@tremplin-utc.net>
Description
-----------
This driver provides support for the accelerometer found in various HP laptops
sporting the feature officially called "HP Mobile Data Protection System 3D" or
"HP 3D DriveGuard". It detect automatically laptops with this sensor. Known models
(for now the HP 2133, nc6420, nc2510, nc8510, nc84x0, nw9440 and nx9420) will
have their axis automatically oriented on standard way (eg: you can directly
play neverball). The accelerometer data is readable via
/sys/devices/platform/lis3lv02d.
Sysfs attributes under /sys/devices/platform/lis3lv02d/:
position - 3D position that the accelerometer reports. Format: "(x,y,z)"
calibrate - read: values (x, y, z) that are used as the base for input class device operation.
write: forces the base to be recalibrated with the current position.
rate - reports the sampling rate of the accelerometer device in HZ
This driver also provides an absolute input class device, allowing
the laptop to act as a pinball machine-esque joystick.
Axes orientation
----------------
For better compatibility between the various laptops. The values reported by
the accelerometer are converted into a "standard" organisation of the axes
(aka "can play neverball out of the box"):
* When the laptop is horizontal the position reported is about 0 for X and Y
and a positive value for Z
* If the left side is elevated, X increases (becomes positive)
* If the front side (where the touchpad is) is elevated, Y decreases (becomes negative)
* If the laptop is put upside-down, Z becomes negative
If your laptop model is not recognized (cf "dmesg"), you can send an email to the
authors to add it to the database. When reporting a new laptop, please include
the output of "dmidecode" plus the value of /sys/devices/platform/lis3lv02d/position
in these four cases.

Datasheet: Publically available at the IDT website
Author: Darrick J. Wong
Description
-----------
This driver implements support for the IDT ICS932S401 chip family.
This chip has 4 clock outputs--a base clock for the CPU (which is likely
multiplied to get the real CPU clock), a system clock, a PCI clock, a USB
clock, and a reference clock. The driver reports selected and actual
frequency. If spread spectrum mode is enabled, the driver also reports by what
percent the clock signal is being spread, which should be between 0 and -0.5%.
All frequencies are reported in KHz.
The ICS932S401 monitors all inputs continuously. The driver will not read
the registers more often than once every other second.
Special Features
----------------
The clocks could be reprogrammed to increase system speed. I will not help you
do this, as you risk damaging your system!

Kernel driver for omap HDQ/1-wire module.
========================================
Supported chips:
================
HDQ/1-wire controller on the TI OMAP 2430/3430 platforms.
A useful link about HDQ basics:
===============================
http://focus.ti.com/lit/an/slua408/slua408.pdf
Description:
============
The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware
protocol of the master functions of the Benchmark HDQ and the Dallas
Semiconductor 1-Wire protocols. These protocols use a single wire for
communication between the master (HDQ/1-Wire controller) and the slave
(HDQ/1-Wire external compliant device).
A typical application of the HDQ/1-Wire module is the communication with battery
monitor (gas gauge) integrated circuits.
The controller supports operation in both HDQ and 1-wire mode. The essential
difference between the HDQ and 1-wire mode is how the slave device responds to
initialization pulse.In HDQ mode, the firmware does not require the host to
create an initialization pulse to the slave.However, the slave can be reset by
using an initialization pulse (also referred to as a break pulse).The slave
does not respond with a presence pulse as it does in the 1-Wire protocol.
Remarks:
========
The driver (drivers/w1/masters/omap_hdq.c) supports the HDQ mode of the
controller. In this mode, as we can not read the ID which obeys the W1
spec(family:id:crc), a module parameter can be passed to the driver which will
be used to calculate the CRC and pass back an appropriate slave ID to the W1
core.
By default the master driver and the BQ slave i/f
driver(drivers/w1/slaves/w1_bq27000.c) sets the ID to 1.
Please note to load both the modules with a different ID if required, but note
that the ID used should be same for both master and slave driver loading.
e.g:
insmod omap_hdq.ko W1_ID=2
inamod w1_bq27000.ko F_ID=2
