The initial design is to go in your car, but you can use it at home, on a
|
||||
boat... almost anywhere. The principle is to store CD-quality music using
|
||||
MPEG technology onto a hard disk in the unit, and use the power of the
|
||||
embedded computer to serve up the music you want.

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.

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).

Later on the ftraced kernel thread is awoken and will again call

kstop_machine if new functions have been recorded. The ftraced thread
|

will change all calls to mcount to "nop". Just calling mcount
|
||||
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

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

exist.

If there are recorded calls to mcount, any write to the ftraced_enabled

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
|
||||
|
||||
* reg_10
|
||||
|
||||

|
||||
B C T D L A S E
|
||||
|
||||
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
|
||||
|
||||
* reg_11
|
||||
|
||||
bit 7 6 5 4 3 2 1 0
|
||||
1 0 0 H V 1 F P
|
||||
|
||||
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
|
||||
|
||||
smart edge cursor speed (0x02 = slow, 0x03 = medium, 0x04 = fast)
|
||||
|
||||
* reg_26
|
||||
|
||||
smart edge activation area width?

|

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.

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.
