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

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.

When dynamic ftrace is initialized, it calls kstop_machine to make
|
||||
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"
|
||||
function. After this, the first time a kernel function is called,
|
||||
it has the calling address saved in a hash table.
|
||||
At compile time every C file object is run through the
|
||||
recordmcount.pl script (located in the scripts directory). This
|
||||
script will process the C object using objdump to find all the
|
||||
locations in the .text section that call mcount. (Note, only
|

the .text section is processed, since processing other sections

like .init.text may cause races due to those sections being freed).

kstop_machine if new functions have been recorded. The ftraced thread

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
|
||||
scans this table and updates all the locations into nops. It also
|
||||
records the locations, which are added to the available_filter_functions
|

list. Modules are processed as they are loaded and before they are
|
||||
executed. When a module is unloaded, it also removes its functions from
|
||||
the ftrace function list. This is automatic in the module unload
|
||||
code, and the module author does not need to worry about it.
|
||||
|
||||
When tracing is enabled, kstop_machine is called to prevent races
|
||||
with the CPUS executing code being modified (which can cause the
|

As mentioned above, when dynamic ftrace is configured in, a kernel

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
|
||||
in these four cases.

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

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 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.

|
||||
acpi.debug_level= [HW,ACPI,ACPI_DEBUG]
|
||||
Format: <int>
|
||||
Each bit of the <int> indicates an ACPI debug layer,
|
||||
1: enable, 0: disable. It is useful for boot time
|
||||
debugging. After system has booted up, it can be set
|
||||
via /sys/module/acpi/parameters/debug_layer.
|
||||
CONFIG_ACPI_DEBUG must be enabled for this to produce any output.
|
||||
Available bits (add the numbers together) to enable debug output
|
||||
for specific parts of the ACPI subsystem:
|
||||
0x01 utilities 0x02 hardware 0x04 events 0x08 tables
|
||||
0x10 namespace 0x20 parser 0x40 dispatcher
|
||||
0x80 executer 0x100 resources 0x200 acpica debugger
|
||||
0x400 os services 0x800 acpica disassembler.
|
||||
The number can be in decimal or prefixed with 0x in hex.
|
||||
Warning: Many of these options can produce a lot of
|
||||
output and make your system unusable. Be very careful.
|
||||
CONFIG_ACPI_DEBUG must be enabled to produce any ACPI
|
||||
debug output. Bits in debug_layer correspond to a
|
||||
_COMPONENT in an ACPI source file, e.g.,
|
||||
#define _COMPONENT ACPI_PCI_COMPONENT
|
||||
Bits in debug_level correspond to a level in
|
||||
ACPI_DEBUG_PRINT statements, e.g.,
|
||||
ACPI_DEBUG_PRINT((ACPI_DB_INFO, ...
|
||||
See Documentation/acpi/debug.txt for more information
|
||||
about debug layers and levels.
|
||||
|
||||
acpi.debug_level= [HW,ACPI]
|
||||
Format: <int>
|
||||
Each bit of the <int> indicates an ACPI debug level,
|
||||
which corresponds to the level in an ACPI_DEBUG_PRINT
|
||||
statement. After system has booted up, this mask
|
||||
can be set via /sys/module/acpi/parameters/debug_level.
|
||||
Enable AML "Debug" output, i.e., stores to the Debug
|
||||
object while interpreting AML:
|
||||
acpi.debug_layer=0xffffffff acpi.debug_level=0x2
|
||||
Enable PCI/PCI interrupt routing info messages:
|
||||
acpi.debug_layer=0x400000 acpi.debug_level=0x4
|
||||
Enable all messages related to ACPI hardware:
|
||||
acpi.debug_layer=0x2 acpi.debug_level=0xffffffff
|
||||
|
||||
CONFIG_ACPI_DEBUG must be enabled for this to produce
|
||||
any output. The number can be in decimal or prefixed
|
||||
with 0x in hex. Some of these options produce so much
|
||||
output that the system is unusable.
|
||||

||||
The following global components are defined by the
|
||||
ACPI CA:
|
||||
0x01 error
|
||||
0x02 warn
|
||||
0x04 init
|
||||
0x08 debug object
|

||||
0x40 parse
|
||||
0x80 load
|

output and make your system unusable. Be very careful.
|
||||
Some values produce so much output that the system is
|
||||
unusable. The "log_buf_len" parameter may be useful
|
||||
if you need to capture more output.

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.
|
||||

||||

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
