1 ACPI Debug Output
2
3
4The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
5output. This document describes how to use this facility.
6
7Compile-time configuration
8--------------------------
9
10ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG. If this config
11option is turned off, the debug messages are not even built into the
12kernel.
13
14Boot- and run-time configuration
15--------------------------------
16
17When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
18you're interested in. At boot-time, use the acpi.debug_layer and
19acpi.debug_level kernel command line options. After boot, you can use the
20debug_layer and debug_level files in /sys/module/acpi/parameters/ to control
21the debug messages.
22
23debug_layer (component)
24-----------------------
25
26The "debug_layer" is a mask that selects components of interest, e.g., a
27specific driver or part of the ACPI interpreter. To build the debug_layer
28bitmask, look for the "#define _COMPONENT" in an ACPI source file.
29
30You can set the debug_layer mask at boot-time using the acpi.debug_layer
31command line argument, and you can change it after boot by writing values
32to /sys/module/acpi/parameters/debug_layer.
33
34The possible components are defined in include/acpi/acoutput.h and
35include/acpi/acpi_drivers.h. Reading /sys/module/acpi/parameters/debug_layer
36shows the supported mask values, currently these:

65 ACPI_PROCESSOR_COMPONENT 0x20000000
66
67debug_level
68-----------
69
70The "debug_level" is a mask that selects different types of messages, e.g.,
71those related to initialization, method execution, informational messages, etc.
72To build debug_level, look at the level specified in an ACPI_DEBUG_PRINT()
73statement.
74
75The ACPI interpreter uses several different levels, but the Linux
76ACPI core and ACPI drivers generally only use ACPI_LV_INFO.
77
78You can set the debug_level mask at boot-time using the acpi.debug_level
79command line argument, and you can change it after boot by writing values
80to /sys/module/acpi/parameters/debug_level.

116--------
117
118For example, drivers/acpi/bus.c contains this:
119
120 #define _COMPONENT ACPI_BUS_COMPONENT
121 ...
122 ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Device insertion detected\n"));
123
124To turn on this message, set the ACPI_BUS_COMPONENT bit in acpi.debug_layer
125and the ACPI_LV_INFO bit in acpi.debug_level. (The ACPI_DEBUG_PRINT
126statement uses ACPI_DB_INFO, which is macro based on the ACPI_LV_INFO
127definition.)
128
129Enable all AML "Debug" output (stores to the Debug object while interpreting
130AML) during boot:
131
132 acpi.debug_layer=0xffffffff acpi.debug_level=0x2
133
134Enable PCI and PCI interrupt routing debug messages:
135
136 acpi.debug_layer=0x400000 acpi.debug_level=0x4
137
138Enable all ACPI hardware-related messages:
139
140 acpi.debug_layer=0x2 acpi.debug_level=0xffffffff
141
142Enable all ACPI_DB_INFO messages after boot:
143
144 # echo 0x4 > /sys/module/acpi/parameters/debug_level
145
146Show all valid component values:
147
148 # cat /sys/module/acpi/parameters/debug_layer

18Overview
19--------
20
21This driver implements the support for Linux of Silicon Labs (Silabs)
22C2 Interface used for in-system programming of micro controllers.
23
24By using this driver you can reprogram the in-system flash without EC2
25or EC3 debug adapter. This solution is also useful in those systems
26where the micro controller is connected via special GPIOs pins.
27
28References
29----------
30
31The C2 Interface main references are at (http://www.silabs.com)
32Silicon Laboratories site], see:

40however it implements a two wire serial communication protocol (bit
41banging) designed to enable in-system programming, debugging, and
42boundary-scan testing on low pin-count Silicon Labs devices. Currently
43this code supports only flash programming but extensions are easy to
44add.
45
46Using the driver
47----------------
48
49Once the driver is loaded you can use sysfs support to get C2port's
50info or read/write in-system flash.
51
52# ls /sys/class/c2port/c2port0/
53access flash_block_size flash_erase rev_id
54dev_id flash_blocks_num flash_size subsystem/
55flash_access flash_data reset uevent
56
57Initially the C2port access is disabled since you hardware may have
58such lines multiplexed with other devices so, to get access to the
59C2port, you need the command:
60
61# echo 1 > /sys/class/c2port/c2port0/access
62
63after that you should read the device ID and revision ID of the
64connected micro controller:
65
66# cat /sys/class/c2port/c2port0/dev_id
678
68# cat /sys/class/c2port/c2port0/rev_id
691
70
71However, for security reasons, the in-system flash access in not
72enabled yet, to do so you need the command:
73
74# echo 1 > /sys/class/c2port/c2port0/flash_access
75
76After that you can read the whole flash:
77
78# cat /sys/class/c2port/c2port0/flash_data > image
79
80erase it:
81
82# echo 1 > /sys/class/c2port/c2port0/flash_erase
83
84and write it:
85
86# cat image > /sys/class/c2port/c2port0/flash_data
87
88after writing you have to reset the device to execute the new code:
89
90# echo 1 > /sys/class/c2port/c2port0/reset

12Description
13-----------
14
15This driver implements support for the Analog Devices ADT7462 chip family.
16
17This chip is a bit of a beast. It has 8 counters for measuring fan speed. It
18can also measure 13 voltages or 4 temperatures, or various combinations of the
19two. See the chip documentation for more details about the exact set of
20configurations. This driver does not allow one to configure the chip; that is
21left to the system designer.
22
23A sophisticated control system for the PWM outputs is designed into the ADT7462
24that allows fan speed to be adjusted automatically based on any of the three
25temperature sensors. Each PWM output is individually adjustable and
26programmable. Once configured, the ADT7462 will adjust the PWM outputs in
27response to the measured temperatures without further host intervention. This
28feature can also be disabled for manual control of the PWM's.
29
30Each of the measured inputs (voltage, temperature, fan speed) has
31corresponding high/low limit values. The ADT7462 will signal an ALARM if
32any measured value exceeds either limit.
33
34The ADT7462 samples all inputs continuously. The driver will not read
35the registers more often than once every other second. Further,
36configuration data is only read once per minute.
37
38Special Features
39----------------
40
41The ADT7462 have a 10-bit ADC and can therefore measure temperatures
42with 0.25 degC resolution.
43
44The Analog Devices datasheet is very detailed and describes a procedure for
45determining an optimal configuration for the automatic PWM control.
46
47The driver will report sensor labels when it is able to determine that
48information from the configuration registers.
49
50Configuration Notes
51-------------------
52
53Besides standard interfaces driver adds the following:
54
55* PWM Control
56
57* pwm#_auto_point1_pwm and temp#_auto_point1_temp and
58* pwm#_auto_point2_pwm and temp#_auto_point2_temp -
59
60point1: Set the pwm speed at a lower temperature bound.
61point2: Set the pwm speed at a higher temperature bound.
62
63The ADT7462 will scale the pwm between the lower and higher pwm speed when
64the temperature is between the two temperature boundaries. PWM values range
65from 0 (off) to 255 (full speed). Fan speed will be set to maximum when the
66temperature sensor associated with the PWM control exceeds temp#_max.

13Description
14-----------
15
16This driver provides support for the accelerometer found in various HP laptops
17sporting the feature officially called "HP Mobile Data Protection System 3D" or
18"HP 3D DriveGuard". It detect automatically laptops with this sensor. Known models
19(for now the HP 2133, nc6420, nc2510, nc8510, nc84x0, nw9440 and nx9420) will
20have their axis automatically oriented on standard way (eg: you can directly
21play neverball). The accelerometer data is readable via
22/sys/devices/platform/lis3lv02d.
23
24Sysfs attributes under /sys/devices/platform/lis3lv02d/:
25position - 3D position that the accelerometer reports. Format: "(x,y,z)"
26calibrate - read: values (x, y, z) that are used as the base for input class device operation.
27 write: forces the base to be recalibrated with the current position.
28rate - reports the sampling rate of the accelerometer device in HZ
29
30This driver also provides an absolute input class device, allowing
31the laptop to act as a pinball machine-esque joystick.
32
33Axes orientation
34----------------
35
36For better compatibility between the various laptops. The values reported by
37the accelerometer are converted into a "standard" organisation of the axes
38(aka "can play neverball out of the box"):
39 * When the laptop is horizontal the position reported is about 0 for X and Y
40and a positive value for Z
41 * If the left side is elevated, X increases (becomes positive)
42 * If the front side (where the touchpad is) is elevated, Y decreases (becomes negative)
43 * If the laptop is put upside-down, Z becomes negative
44
45If your laptop model is not recognized (cf "dmesg"), you can send an email to the
46authors to add it to the database. When reporting a new laptop, please include
47the output of "dmidecode" plus the value of /sys/devices/platform/lis3lv02d/position
48in these four cases.

12Description
13-----------
14
15This driver implements support for the IDT ICS932S401 chip family.
16
17This chip has 4 clock outputs--a base clock for the CPU (which is likely
18multiplied to get the real CPU clock), a system clock, a PCI clock, a USB
19clock, and a reference clock. The driver reports selected and actual
20frequency. If spread spectrum mode is enabled, the driver also reports by what
21percent the clock signal is being spread, which should be between 0 and -0.5%.
22All frequencies are reported in KHz.
23
24The ICS932S401 monitors all inputs continuously. The driver will not read
25the registers more often than once every other second.
26
27Special Features
28----------------
29
30The clocks could be reprogrammed to increase system speed. I will not help you
31do this, as you risk damaging your system!

1Kernel driver for omap HDQ/1-wire module.
2========================================
3
4Supported chips:
5================
6 HDQ/1-wire controller on the TI OMAP 2430/3430 platforms.
7
8A useful link about HDQ basics:
9===============================
10http://focus.ti.com/lit/an/slua408/slua408.pdf
11
12Description:
13============
14The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware
15protocol of the master functions of the Benchmark HDQ and the Dallas
16Semiconductor 1-Wire protocols. These protocols use a single wire for
17communication between the master (HDQ/1-Wire controller) and the slave
18(HDQ/1-Wire external compliant device).
19
20A typical application of the HDQ/1-Wire module is the communication with battery
21monitor (gas gauge) integrated circuits.
22
23The controller supports operation in both HDQ and 1-wire mode. The essential
24difference between the HDQ and 1-wire mode is how the slave device responds to
25initialization pulse.In HDQ mode, the firmware does not require the host to
26create an initialization pulse to the slave.However, the slave can be reset by
27using an initialization pulse (also referred to as a break pulse).The slave
28does not respond with a presence pulse as it does in the 1-Wire protocol.
29
30Remarks:
31========
32The driver (drivers/w1/masters/omap_hdq.c) supports the HDQ mode of the
33controller. In this mode, as we can not read the ID which obeys the W1
34spec(family:id:crc), a module parameter can be passed to the driver which will
35be used to calculate the CRC and pass back an appropriate slave ID to the W1
36core.
37
38By default the master driver and the BQ slave i/f
39driver(drivers/w1/slaves/w1_bq27000.c) sets the ID to 1.
40Please note to load both the modules with a different ID if required, but note
41that the ID used should be same for both master and slave driver loading.
42
43e.g:
44insmod omap_hdq.ko W1_ID=2
45inamod w1_bq27000.ko F_ID=2

843 This driver provides support for the LIS3LV02Dx accelerometer. In
844 particular, it can be found in a number of HP laptops, which have the
845 "Mobile Data Protection System 3D" or "3D DriveGuard" feature. On such
846 systems the driver should load automatically (via ACPI). The
847 accelerometer might also be found in other systems, connected via SPI
848 or I2C. The accelerometer data is readable via

10 This option enables support for Silicon Labs C2 port used to
11 program Silicon micro controller chips (and other 8051 compatible).
12
13 If your board have no such micro controllers you don't need this
14 interface at all.
15
16 To compile this driver as a module, choose M here: the module will
17 be called c2port_core. Note that you also need a client module
18 usually called c2port-*.

504 * Watch removals suck violently. To kick the watch out we need (in this
505 * order) inode->inotify_mutex and ih->mutex. That's fine if we have
506 * a hold on inode; however, for all other cases we need to make damn sure
507 * we don't race with umount. We can *NOT* just grab a reference to a
508 * watch - inotify_unmount_inodes() will happily sail past it and we'll end
509 * with reference to inode potentially outliving its superblock. Ideally
510 * we just want to grab an active reference to superblock if we can; that
511 * will make sure we won't go into inotify_umount_inodes() until we are
512 * done. Cleanup is just deactivate_super(). However, that leaves a messy
513 * case - what if we *are* racing with umount() and active references to
514 * superblock can't be acquired anymore? We can bump ->s_count, grab
515 * ->s_umount, which will almost certainly wait until the superblock is shut
516 * down and the watch in question is pining for fjords. That's fine, but
517 * there is a problem - we might have hit the window between ->s_active
518 * getting to 0 / ->s_count - below S_BIAS (i.e. the moment when superblock
519 * is past the point of no return and is heading for shutdown) and the
520 * moment when deactivate_super() acquires ->s_umount. We could just do
521 * drop_super() yield() and retry, but that's rather antisocial and this
522 * stuff is luser-triggerable. OTOH, having grabbed ->s_umount and having
523 * found that we'd got there first (i.e. that ->s_root is non-NULL) we know
524 * that we won't race with inotify_umount_inodes(). So we could grab a
525 * reference to watch and do the rest as above, just with drop_super() instead
526 * of deactivate_super(), right? Wrong. We had to drop ih->mutex before we
527 * could grab ->s_umount. So the watch could've been gone already.
528 *
529 * That still can be dealt with - we need to save watch->wd, do idr_find()
530 * and compare its result with our pointer. If they match, we either have
531 * the damn thing still alive or we'd lost not one but two races at once,
532 * the watch had been killed and a new one got created with the same ->wd
533 * at the same address. That couldn't have happened in inotify_destroy(),
534 * but inotify_rm_wd() could run into that. Still, "new one got created"
535 * is not a problem - we have every right to kill it or leave it alone,
536 * whatever's more convenient.
537 *
538 * So we can use idr_find(...) == watch && watch->inode->i_sb == sb as
539 * "grab it and kill it" check. If it's been our original watch, we are
540 * fine, if it's a newcomer - nevermind, just pretend that we'd won the
541 * race and kill the fscker anyway; we are safe since we know that its
542 * superblock won't be going away.
543 *
544 * And yes, this is far beyond mere "not very pretty"; so's the entire
545 * concept of inotify to start with.
