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:

||||

|

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:
|
||||

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

The Kenwood KCA-R6A remote control generates a sequence like the following:
|
||||
|
||||
Go low for approx 16T (Around 9000us)
|
||||
Go high for approx 8T (Around 4000us)
|
||||
Go low for less than 2T (Around 750us)
|
||||
|
||||
For each of the 32 bits
|
||||
Go high for more than 2T (Around 1500us) == 1
|
||||
Go high for less than T (Around 400us) == 0
|
||||
Go low for less than 2T (Around 750us)
|
||||
|
||||
Rather than repeat a signal when the button is held down certain buttons
|
||||
generate the following code to indicate repetition.
|
||||
|
||||
Go low for approx 16T
|
||||
Go high for approx 4T
|
||||
Go low for less than 2T
|
||||
|
||||
(By removing the <2T from the start of the sequence and placing at the end
|
||||
it can be considered a stop bit but I found it easier to deal with it at
|
||||
the start).
|
||||
|
||||
The 32 bits are encoded as XxYy where x and y are the actual data values
|
||||
while X and Y are the logical inverses of the associated data values. Using
|
||||
LSB first yields sensible codes for the numbers.
|
||||
|
||||
All codes are of the form b9xx
|
||||
|
||||
The numeric keys generate the code 0x where x is the number pressed.

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

Gmail (Web GUI)
|
||||
|
||||
If you just have to use Gmail to send patches, it CAN be made to work. It
|
||||
requires a bit of external help, though.
|
||||
|
||||
The first problem is that Gmail converts tabs to spaces. This will
|
||||
totally break your patches. To prevent this, you have to use a different
|
||||
editor. There is a firefox extension called "ViewSourceWith"
|
||||
(https://addons.mozilla.org/en-US/firefox/addon/394) which allows you to
|
||||
edit any text box in the editor of your choice. Configure it to launch
|
||||
your favorite editor. When you want to send a patch, use this technique.
|
||||
Once you have crafted your messsage + patch, save and exit the editor,
|
||||
which should reload the Gmail edit box. GMAIL WILL PRESERVE THE TABS.
|
||||
Hoorah. Apparently you can cut-n-paste literal tabs, but Gmail will
|
||||
convert those to spaces upon sending!
|
||||
|
||||
The second problem is that Gmail converts tabs to spaces on replies. If
|
||||
you reply to a patch, don't expect to be able to apply it as a patch.
|
||||
|
||||
The last problem is that Gmail will base64-encode any message that has a
|
||||
non-ASCII character. That includes things like European names. Be aware.
|
||||
|
||||
Gmail is not convenient for lkml patches, but CAN be made to work.

max_user_instances

------------------
|

|

This is the maximum number of epoll file descriptors that a single user can

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.

the machine act like a uniprocessor so that it can freely modify code

without worrying about other processors executing that same code. At

initialization, the mcount calls are changed to call a "record_ip"

At compile time every C file object is run through the

locations in the .text section that call mcount. (Note, only

and having mcount return has shown a 10% overhead. By converting

it to a nop, there is no measurable overhead to the system.
|

A new section called "__mcount_loc" is created that holds references

to all the mcount call sites in the .text section. This section is

compiled back into the original object. The final linker will add

all these references into a single table.

On boot up, before SMP is initialized, the dynamic ftrace code

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.

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

-----------
|
||||
|
||||
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.

1. Introduction
|
||||
~~~~~~~~~~~~
|
||||
|
||||
Currently the Linux Elantech touchpad driver is aware of two different
|
||||
hardware versions unimaginatively called version 1 and version 2. Version 1
|
||||
is found in "older" laptops and uses 4 bytes per packet. Version 2 seems to
|
||||
be introduced with the EeePC and uses 6 bytes per packet.
|
||||
|
||||
The driver tries to support both hardware versions and should be compatible
|
||||
with the Xorg Synaptics touchpad driver and its graphical configuration
|
||||
utilities.
|
||||
|
||||
Additionally the operation of the touchpad can be altered by adjusting the
|
||||
contents of some of its internal registers. These registers are represented
|
||||
by the driver as sysfs entries under /sys/bus/serio/drivers/psmouse/serio?
|
||||
that can be read from and written to.
|
||||
|
||||
Currently only the registers for hardware version 1 are somewhat understood.
|
||||
Hardware version 2 seems to use some of the same registers but it is not
|
||||
known whether the bits in the registers represent the same thing or might
|
||||
have changed their meaning.
|
||||
|
||||
On top of that, some register settings have effect only when the touchpad is
|
||||
in relative mode and not in absolute mode. As the Linux Elantech touchpad
|
||||
driver always puts the hardware into absolute mode not all information
|
||||
mentioned below can be used immediately. But because there is no freely
|
||||
available Elantech documentation the information is provided here anyway for
|
||||
completeness sake.

2. Extra knobs
|
||||
~~~~~~~~~~~
|
||||
|
||||
Currently the Linux Elantech touchpad driver provides two extra knobs under
|
||||
/sys/bus/serio/drivers/psmouse/serio? for the user.
|
||||
|
||||
* debug
|
||||
|
||||
Turn different levels of debugging ON or OFF.
|
||||
|
||||
By echoing "0" to this file all debugging will be turned OFF.
|
||||
|
||||
Currently a value of "1" will turn on some basic debugging and a value of
|
||||
"2" will turn on packet debugging. For hardware version 1 the default is
|
||||
OFF. For version 2 the default is "1".
|
||||
|
||||
Turning packet debugging on will make the driver dump every packet
|
||||
received to the syslog before processing it. Be warned that this can
|
||||
generate quite a lot of data!
|
||||
|
||||
* paritycheck
|
||||
|
||||
Turns parity checking ON or OFF.
|
||||
|
||||
By echoing "0" to this file parity checking will be turned OFF. Any
|
||||
non-zero value will turn it ON. For hardware version 1 the default is ON.
|
||||
For version 2 the default it is OFF.
|
||||
|
||||
Hardware version 1 provides basic data integrity verification by
|
||||
calculating a parity bit for the last 3 bytes of each packet. The driver
|
||||
can check these bits and reject any packet that appears corrupted. Using
|
||||
this knob you can bypass that check.
|
||||
|
||||
It is not known yet whether hardware version 2 provides the same parity
|
||||
bits. Hence checking is disabled by default. Currently even turning it on
|
||||
will do nothing.

|

3.1 Registers
|
||||
~~~~~~~~~
|
||||
|
||||
By echoing a hexadecimal value to a register it contents can be altered.
|
||||
|
||||
For example:

||||
|
||||
echo -n 0x16 > reg_10

|
||||
|
||||
E: 1 = enable smart edges unconditionally
|
||||
S: 1 = enable smart edges only when dragging
|
||||
A: 1 = absolute mode (needs 4 byte packets, see reg_11)
|
||||
L: 1 = enable drag lock (see reg_22)
|
||||
D: 1 = disable dynamic resolution
|
||||
T: 1 = disable tapping
|
||||
C: 1 = enable corner tap
|
||||
B: 1 = swap left and right button
|

|
||||
|
||||
P: 1 = enable parity checking for relative mode
|
||||
F: 1 = enable native 4 byte packet mode
|
||||
V: 1 = enable vertical scroll area
|
||||
H: 1 = enable horizontal scroll area
|
||||
|
||||
* reg_20
|
||||
|
||||
single finger width?
|
||||
|
||||
* reg_21
|
||||
|
||||
scroll area width (small: 0x40 ... wide: 0xff)
|
||||
|
||||
* reg_22
|
||||
|
||||
drag lock time out (short: 0x14 ... long: 0xfe;
|
||||
0xff = tap again to release)
|
||||
|
||||
* reg_23
|
||||
|
||||
tap make timeout?
|
||||
|
||||
* reg_24
|
||||
|
||||
tap release timeout?
|
||||
|
||||
* reg_25
|

|

The io_mapping functions in linux/io-mapping.h provide an abstraction for
|
||||
efficiently mapping small regions of an I/O device to the CPU. The initial
|
||||
usage is to support the large graphics aperture on 32-bit processors where
|
||||
ioremap_wc cannot be used to statically map the entire aperture to the CPU
|
||||
as it would consume too much of the kernel address space.
|
||||
|
||||
A mapping object is created during driver initialization using
|
||||
|
||||
struct io_mapping *io_mapping_create_wc(unsigned long base,
|
||||
unsigned long size)
|
||||
|
||||
'base' is the bus address of the region to be made
|
||||
mappable, while 'size' indicates how large a mapping region to
|
||||
enable. Both are in bytes.
|
||||
|
||||
This _wc variant provides a mapping which may only be used
|
||||
with the io_mapping_map_atomic_wc or io_mapping_map_wc.
|
||||
|
||||
With this mapping object, individual pages can be mapped either atomically
|
||||
or not, depending on the necessary scheduling environment. Of course, atomic
|
||||
maps are more efficient:
|
||||
|
||||
void *io_mapping_map_atomic_wc(struct io_mapping *mapping,
|
||||
unsigned long offset)
|
||||
|
||||
'offset' is the offset within the defined mapping region.
|
||||
Accessing addresses beyond the region specified in the
|
||||
creation function yields undefined results. Using an offset
|
||||
which is not page aligned yields an undefined result. The
|
||||
return value points to a single page in CPU address space.
|
||||
|
||||
This _wc variant returns a write-combining map to the
|
||||
page and may only be used with mappings created by
|
||||
io_mapping_create_wc
|
||||
|
||||
Note that the task may not sleep while holding this page
|
||||
mapped.
|
||||
|
||||
void io_mapping_unmap_atomic(void *vaddr)
|
||||
|
||||
'vaddr' must be the the value returned by the last
|
||||
io_mapping_map_atomic_wc call. This unmaps the specified
|
||||
page and allows the task to sleep once again.
|
||||
|
||||
If you need to sleep while holding the lock, you can use the non-atomic
|
||||
variant, although they may be significantly slower.
|
||||
|
||||
void *io_mapping_map_wc(struct io_mapping *mapping,
|
||||
unsigned long offset)
|
||||
|
||||
This works like io_mapping_map_atomic_wc except it allows
|
||||
the task to sleep while holding the page mapped.
|
||||
|
||||
void io_mapping_unmap(void *vaddr)
|
||||
|
||||
This works like io_mapping_unmap_atomic, except it is used
|
||||
for pages mapped with io_mapping_map_wc.
|
||||
|
||||
At driver close time, the io_mapping object must be freed:
|
||||
|
||||
void io_mapping_free(struct io_mapping *mapping)
|
||||
|
||||
Current Implementation:
|
||||
|
||||
The initial implementation of these functions uses existing mapping
|
||||
mechanisms and so provides only an abstraction layer and no new
|
||||
functionality.
|
||||
|
||||
On 64-bit processors, io_mapping_create_wc calls ioremap_wc for the whole
|
||||
range, creating a permanent kernel-visible mapping to the resource. The
|
||||
map_atomic and map functions add the requested offset to the base of the
|
||||
virtual address returned by ioremap_wc.
|
||||
|
||||
On 32-bit processors with HIGHMEM defined, io_mapping_map_atomic_wc uses
|
||||
kmap_atomic_pfn to map the specified page in an atomic fashion;
|
||||
kmap_atomic_pfn isn't really supposed to be used with device pages, but it
|
||||
provides an efficient mapping for this usage.
|
||||
|
||||
On 32-bit processors without HIGHMEM defined, io_mapping_map_atomic_wc and
|
||||
io_mapping_map_wc both use ioremap_wc, a terribly inefficient function which
|
||||
performs an IPI to inform all processors about the new mapping. This results
|
||||
in a significant performance penalty.

|
||||
Required properties:
|
||||
- compatible : should be "fsl-diu".
|
||||
- reg : should contain at least address and length of the DIU register
|
||||
set.
|
||||
- Interrupts : one DIU interrupt should be describe here.
|
||||
|
||||
Example (MPC8610HPCD)
|
||||
display@2c000 {
|
||||
compatible = "fsl,diu";
|
||||
reg = <0x2c000 100>;

Driver for USB radios for the Silicon Labs Si470x FM Radio Receivers
|

Copyright (c) 2008 Tobias Lorenz <tobias.lorenz@gmx.net>
|
||||
|
||||
|
||||
Information from Silicon Labs
|
||||
=============================
|
||||
Silicon Laboratories is the manufacturer of the radio ICs, that nowadays are the
|
||||
most often used radio receivers in cell phones. Usually they are connected with
|
||||
I2C. But SiLabs also provides a reference design, which integrates this IC,
|
||||
together with a small microcontroller C8051F321, to form a USB radio.
|
||||
Part of this reference design is also a radio application in binary and source
|
||||
code. The software also contains an automatic firmware upgrade to the most
|
||||
current version. Information on these can be downloaded here:
|
||||
http://www.silabs.com/usbradio
|
||||
|
||||
|
||||
Supported ICs
|
||||
=============
|
||||
The following ICs have a very similar register set, so that they are or will be
|
||||
supported somewhen by the driver:
|
||||
- Si4700: FM radio receiver
|
||||
- Si4701: FM radio receiver, RDS Support
|
||||
- Si4702: FM radio receiver
|
||||
- Si4703: FM radio receiver, RDS Support
|
||||
- Si4704: FM radio receiver, no external antenna required
|
||||
- Si4705: FM radio receiver, no external antenna required, RDS support, Dig I/O
|
||||
- Si4706: Enhanced FM RDS/TMC radio receiver, no external antenna required, RDS
|
||||
Support
|
||||
- Si4707: Dedicated weather band radio receiver with SAME decoder, RDS Support
|
||||
- Si4708: Smallest FM receivers
|
||||
- Si4709: Smallest FM receivers, RDS Support
|
||||
More information on these can be downloaded here:
|
||||
http://www.silabs.com/products/mcu/Pages/USBFMRadioRD.aspx
|
||||
|
||||
|
||||
Supported USB devices
|
||||
=====================
|
||||
Currently the following USB radios (vendor:product) with the Silicon Labs si470x
|
||||
chips are known to work:
|
||||
- 10c4:818a: Silicon Labs USB FM Radio Reference Design
|
||||
- 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music) (RDX-155-EF)
|
||||
- 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
|
||||
|
||||
|
||||
Software
|
||||
========
|
||||
Testing is usually done with most application under Debian/testing:
|
||||
- fmtools - Utility for managing FM tuner cards
|
||||
- gnomeradio - FM-radio tuner for the GNOME desktop
|
||||
- gradio - GTK FM radio tuner
|
||||
- kradio - Comfortable Radio Application for KDE
|
||||
- radio - ncurses-based radio application
|
||||
|
||||
There is also a library libv4l, which can be used. It's going to have a function
|
||||
for frequency seeking, either by using hardware functionality as in radio-si470x
|
||||
or by implementing a function as we currently have in every of the mentioned
|
||||
programs. Somewhen the radio programs should make use of libv4l.
|
||||
|
||||
For processing RDS information, there is a project ongoing at:
|
||||
http://rdsd.berlios.de/
|
||||
|
||||
There is currently no project for making TMC sentences human readable.
|
||||
|
||||
|
||||
Audio Listing
|
||||
=============
|
||||
USB Audio is provided by the ALSA snd_usb_audio module. It is recommended to
|
||||
also select SND_USB_AUDIO, as this is required to get sound from the radio. For
|
||||
listing you have to redirect the sound, for example using one of the following
|
||||
commands.
|
||||
|
||||
If you just want to test audio (very poor quality):
|
||||
cat /dev/dsp1 > /dev/dsp
|
||||
|
||||
If you use OSS try:
|
||||
sox -2 --endian little -r 96000 -t oss /dev/dsp1 -t oss /dev/dsp
|
||||
|
||||
If you use arts try:
|
||||
arecord -D hw:1,0 -r96000 -c2 -f S16_LE | artsdsp aplay -B -
|
||||
|
||||
|
||||
Module Parameters
|
||||
=================
|
||||
After loading the module, you still have access to some of them in the sysfs
|
||||
mount under /sys/module/radio_si470x/parameters. The contents of read-only files
|
||||
(0444) are not updated, even if space, band and de are changed using private
|
||||
video controls. The others are runtime changeable.
|
||||
|
||||
|
||||
Errors
|
||||
======
|
||||
Increase tune_timeout, if you often get -EIO errors.
|
||||
|
||||
When timed out or band limit is reached, hw_freq_seek returns -EAGAIN.
|
||||
|
||||
If you get any errors from snd_usb_audio, please report them to the ALSA people.
|
||||
|
||||
|
||||
Open Issues
|
||||
===========
|
||||
V4L minor device allocation and parameter setting is not perfect. A solution is
|
||||
currently under discussion.
|
||||
|
||||
There is an USB interface for downloading/uploading new firmware images. Support
|
||||
for it can be implemented using the request_firmware interface.
|
||||
|
||||
There is a RDS interrupt mode. The driver is already using the same interface
|
||||
for polling RDS information, but is currently not using the interrupt mode.
|
||||
|
||||
There is a LED interface, which can be used to override the LED control
|
||||
programmed in the firmware. This can be made available using the LED support
|
||||
functions in the kernel.

===============================

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

By default the master driver and the BQ slave i/f

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.
