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:
37

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.
81
82The possible levels are defined in include/acpi/acoutput.h. Reading
83/sys/module/acpi/parameters/debug_level shows the supported mask values,
84currently these:
85
86 ACPI_LV_INIT 0x00000001
87 ACPI_LV_DEBUG_OBJECT 0x00000002
88 ACPI_LV_INFO 0x00000004

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.)

3The initial design is to go in your car, but you can use it at home, on a
4boat... almost anywhere. The principle is to store CD-quality music using
5MPEG technology onto a hard disk in the unit, and use the power of the
6embedded computer to serve up the music you want.

8The Kenwood KCA-R6A remote control generates a sequence like the following:
9
10Go low for approx 16T (Around 9000us)
11Go high for approx 8T (Around 4000us)
12Go low for less than 2T (Around 750us)
13
14For each of the 32 bits
15 Go high for more than 2T (Around 1500us) == 1
16 Go high for less than T (Around 400us) == 0
17 Go low for less than 2T (Around 750us)
18
19Rather than repeat a signal when the button is held down certain buttons
20generate the following code to indicate repetition.
21
22Go low for approx 16T
23Go high for approx 4T
24Go low for less than 2T
25
26(By removing the <2T from the start of the sequence and placing at the end
27 it can be considered a stop bit but I found it easier to deal with it at
28 the start).
29
30The 32 bits are encoded as XxYy where x and y are the actual data values
31while X and Y are the logical inverses of the associated data values. Using
32LSB first yields sensible codes for the numbers.
33
34All codes are of the form b9xx
35
36The numeric keys generate the code 0x where x is the number pressed.

217Gmail (Web GUI)
218
219If you just have to use Gmail to send patches, it CAN be made to work. It
220requires a bit of external help, though.
221
222The first problem is that Gmail converts tabs to spaces. This will
223totally break your patches. To prevent this, you have to use a different
224editor. There is a firefox extension called "ViewSourceWith"
225(https://addons.mozilla.org/en-US/firefox/addon/394) which allows you to
226edit any text box in the editor of your choice. Configure it to launch
227your favorite editor. When you want to send a patch, use this technique.
228Once you have crafted your messsage + patch, save and exit the editor,
229which should reload the Gmail edit box. GMAIL WILL PRESERVE THE TABS.
230Hoorah. Apparently you can cut-n-paste literal tabs, but Gmail will
231convert those to spaces upon sending!
232
233The second problem is that Gmail converts tabs to spaces on replies. If
234you reply to a patch, don't expect to be able to apply it as a patch.
235
236The last problem is that Gmail will base64-encode any message that has a
237non-ASCII character. That includes things like European names. Be aware.
238
239Gmail is not convenient for lkml patches, but CAN be made to work.

1254As mentioned above, when dynamic ftrace is configured in, a kernel
1255thread wakes up once a second and checks to see if there are mcount
1256calls that need to be converted into nops. If there are not any, then
1257it simply goes back to sleep. But if there are some, it will call
1258kstop_machine to convert the calls to nops.
1259
1260There may be a case in which you do not want this added latency.
1261Perhaps you are doing some audio recording and this activity might
1262cause skips in the playback. There is an interface to disable
1263and enable the "ftraced" kernel thread.

1267This will disable the calling of kstop_machine to update the
1268mcount calls to nops. Remember that there is a large overhead
1269to calling mcount. Without this kernel thread, that overhead will
1270exist.
1271
1272If there are recorded calls to mcount, any write to the ftraced_enabled
1273file will cause the kstop_machine to run. This means that a
1274user can manually perform the updates when they want to by simply
1275echoing a '0' into the ftraced_enabled file.

311. Introduction
32 ~~~~~~~~~~~~
33
34Currently the Linux Elantech touchpad driver is aware of two different
35hardware versions unimaginatively called version 1 and version 2. Version 1
36is found in "older" laptops and uses 4 bytes per packet. Version 2 seems to
37be introduced with the EeePC and uses 6 bytes per packet.
38
39The driver tries to support both hardware versions and should be compatible
40with the Xorg Synaptics touchpad driver and its graphical configuration
41utilities.
42
43Additionally the operation of the touchpad can be altered by adjusting the
44contents of some of its internal registers. These registers are represented
45by the driver as sysfs entries under /sys/bus/serio/drivers/psmouse/serio?
46that can be read from and written to.
47
48Currently only the registers for hardware version 1 are somewhat understood.
49Hardware version 2 seems to use some of the same registers but it is not
50known whether the bits in the registers represent the same thing or might
51have changed their meaning.
52
53On top of that, some register settings have effect only when the touchpad is
54in relative mode and not in absolute mode. As the Linux Elantech touchpad
55driver always puts the hardware into absolute mode not all information
56mentioned below can be used immediately. But because there is no freely
57available Elantech documentation the information is provided here anyway for
58completeness sake.

642. Extra knobs
65 ~~~~~~~~~~~
66
67Currently the Linux Elantech touchpad driver provides two extra knobs under
68/sys/bus/serio/drivers/psmouse/serio? for the user.
69
70* debug
71
72 Turn different levels of debugging ON or OFF.
73
74 By echoing "0" to this file all debugging will be turned OFF.
75
76 Currently a value of "1" will turn on some basic debugging and a value of
77 "2" will turn on packet debugging. For hardware version 1 the default is
78 OFF. For version 2 the default is "1".
79
80 Turning packet debugging on will make the driver dump every packet
81 received to the syslog before processing it. Be warned that this can
82 generate quite a lot of data!
83
84* paritycheck
85
86 Turns parity checking ON or OFF.
87
88 By echoing "0" to this file parity checking will be turned OFF. Any
89 non-zero value will turn it ON. For hardware version 1 the default is ON.
90 For version 2 the default it is OFF.
91
92 Hardware version 1 provides basic data integrity verification by
93 calculating a parity bit for the last 3 bytes of each packet. The driver
94 can check these bits and reject any packet that appears corrupted. Using
95 this knob you can bypass that check.
96
97 It is not known yet whether hardware version 2 provides the same parity
98 bits. Hence checking is disabled by default. Currently even turning it on
99 will do nothing.

1The io_mapping functions in linux/io-mapping.h provide an abstraction for
2efficiently mapping small regions of an I/O device to the CPU. The initial
3usage is to support the large graphics aperture on 32-bit processors where
4ioremap_wc cannot be used to statically map the entire aperture to the CPU
5as it would consume too much of the kernel address space.
6
7A mapping object is created during driver initialization using
8
9 struct io_mapping *io_mapping_create_wc(unsigned long base,
10 unsigned long size)
11
12 'base' is the bus address of the region to be made
13 mappable, while 'size' indicates how large a mapping region to
14 enable. Both are in bytes.
15
16 This _wc variant provides a mapping which may only be used
17 with the io_mapping_map_atomic_wc or io_mapping_map_wc.
18
19With this mapping object, individual pages can be mapped either atomically
20or not, depending on the necessary scheduling environment. Of course, atomic
21maps are more efficient:
22
23 void *io_mapping_map_atomic_wc(struct io_mapping *mapping,
24 unsigned long offset)
25
26 'offset' is the offset within the defined mapping region.
27 Accessing addresses beyond the region specified in the
28 creation function yields undefined results. Using an offset
29 which is not page aligned yields an undefined result. The
30 return value points to a single page in CPU address space.
31
32 This _wc variant returns a write-combining map to the
33 page and may only be used with mappings created by
34 io_mapping_create_wc
35
36 Note that the task may not sleep while holding this page
37 mapped.
38
39 void io_mapping_unmap_atomic(void *vaddr)
40
41 'vaddr' must be the the value returned by the last
42 io_mapping_map_atomic_wc call. This unmaps the specified
43 page and allows the task to sleep once again.
44
45If you need to sleep while holding the lock, you can use the non-atomic
46variant, although they may be significantly slower.
47
48 void *io_mapping_map_wc(struct io_mapping *mapping,
49 unsigned long offset)
50
51 This works like io_mapping_map_atomic_wc except it allows
52 the task to sleep while holding the page mapped.
53
54 void io_mapping_unmap(void *vaddr)
55
56 This works like io_mapping_unmap_atomic, except it is used
57 for pages mapped with io_mapping_map_wc.
58
59At driver close time, the io_mapping object must be freed:
60
61 void io_mapping_free(struct io_mapping *mapping)
62
63Current Implementation:
64
65The initial implementation of these functions uses existing mapping
66mechanisms and so provides only an abstraction layer and no new
67functionality.
68
69On 64-bit processors, io_mapping_create_wc calls ioremap_wc for the whole
70range, creating a permanent kernel-visible mapping to the resource. The
71map_atomic and map functions add the requested offset to the base of the
72virtual address returned by ioremap_wc.
73
74On 32-bit processors with HIGHMEM defined, io_mapping_map_atomic_wc uses
75kmap_atomic_pfn to map the specified page in an atomic fashion;
76kmap_atomic_pfn isn't really supposed to be used with device pages, but it
77provides an efficient mapping for this usage.
78
79On 32-bit processors without HIGHMEM defined, io_mapping_map_atomic_wc and
80io_mapping_map_wc both use ioremap_wc, a terribly inefficient function which
81performs an IPI to inform all processors about the new mapping. This results
82in a significant performance penalty.

6Information from Silicon Labs
7=============================
8Silicon Laboratories is the manufacturer of the radio ICs, that nowadays are the
9most often used radio receivers in cell phones. Usually they are connected with
10I2C. But SiLabs also provides a reference design, which integrates this IC,
11together with a small microcontroller C8051F321, to form a USB radio.
12Part of this reference design is also a radio application in binary and source
13code. The software also contains an automatic firmware upgrade to the most
14current version. Information on these can be downloaded here:
15http://www.silabs.com/usbradio
16
17
18Supported ICs
19=============
20The following ICs have a very similar register set, so that they are or will be
21supported somewhen by the driver:
22- Si4700: FM radio receiver
23- Si4701: FM radio receiver, RDS Support
24- Si4702: FM radio receiver
25- Si4703: FM radio receiver, RDS Support
26- Si4704: FM radio receiver, no external antenna required
27- Si4705: FM radio receiver, no external antenna required, RDS support, Dig I/O
28- Si4706: Enhanced FM RDS/TMC radio receiver, no external antenna required, RDS
29 Support
30- Si4707: Dedicated weather band radio receiver with SAME decoder, RDS Support
31- Si4708: Smallest FM receivers
32- Si4709: Smallest FM receivers, RDS Support
33More information on these can be downloaded here:
34http://www.silabs.com/products/mcu/Pages/USBFMRadioRD.aspx
35
36
37Supported USB devices
38=====================
39Currently the following USB radios (vendor:product) with the Silicon Labs si470x
40chips are known to work:
41- 10c4:818a: Silicon Labs USB FM Radio Reference Design
42- 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music) (RDX-155-EF)
43- 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
44
45
46Software
47========
48Testing is usually done with most application under Debian/testing:
49- fmtools - Utility for managing FM tuner cards
50- gnomeradio - FM-radio tuner for the GNOME desktop
51- gradio - GTK FM radio tuner
52- kradio - Comfortable Radio Application for KDE
53- radio - ncurses-based radio application
54
55There is also a library libv4l, which can be used. It's going to have a function
56for frequency seeking, either by using hardware functionality as in radio-si470x
57or by implementing a function as we currently have in every of the mentioned
58programs. Somewhen the radio programs should make use of libv4l.
59
60For processing RDS information, there is a project ongoing at:
61http://rdsd.berlios.de/
62
63There is currently no project for making TMC sentences human readable.
64
65
66Audio Listing
67=============
68USB Audio is provided by the ALSA snd_usb_audio module. It is recommended to
69also select SND_USB_AUDIO, as this is required to get sound from the radio. For
70listing you have to redirect the sound, for example using one of the following
71commands.
72
73If you just want to test audio (very poor quality):
74cat /dev/dsp1 > /dev/dsp
75
76If you use OSS try:
77sox -2 --endian little -r 96000 -t oss /dev/dsp1 -t oss /dev/dsp
78
79If you use arts try:
80arecord -D hw:1,0 -r96000 -c2 -f S16_LE | artsdsp aplay -B -
81
82
83Module Parameters
84=================
85After loading the module, you still have access to some of them in the sysfs
86mount under /sys/module/radio_si470x/parameters. The contents of read-only files
87(0444) are not updated, even if space, band and de are changed using private
88video controls. The others are runtime changeable.
89
90
91Errors
92======
93Increase tune_timeout, if you often get -EIO errors.
94
95When timed out or band limit is reached, hw_freq_seek returns -EAGAIN.
96
97If you get any errors from snd_usb_audio, please report them to the ALSA people.
98
99
100Open Issues
101===========
102V4L minor device allocation and parameter setting is not perfect. A solution is
103currently under discussion.
104
105There is an USB interface for downloading/uploading new firmware images. Support
106for it can be implemented using the request_firmware interface.
107
108There is a RDS interrupt mode. The driver is already using the same interface
109for polling RDS information, but is currently not using the interrupt mode.
110
111There is a LED interface, which can be used to override the LED control
112programmed in the firmware. This can be made available using the LED support
113functions in the kernel.
