2016-11-10ALSA: doc: ReSTize ALSA-Configuration documentTakashi Iwai3-2330/+2684
A simple conversion from the text file. Since this is the only document specific to the configurations, it's put to the root sound subdirectory. A section describing the obsoleted configure stuff of old alsa-driver tarball got removed. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2016-11-10ALSA: doc: ReSTize HD-Audio-Models documentTakashi Iwai3-324/+519
A simple reformat with the description list of ReST, and the content was kept as is, but renamed as Documentation/sound/hd-audio/models.rst. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-11-10ALSA: doc: ReSTize HD-Audio documentTakashi Iwai3-304/+339
The original HD-Audio.txt was already in asciidoc format, so it's a simple conversion in the end. A new subdirectory, Documentation/sound/hd-audio, is created and the document is moved there with another file name to match better with the recent Documentation tree structure. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-11-10ALSA: doc: ReSTize writing-an-alsa-driver documentTakashi Iwai2-0/+4220
Another simple conversion from DocBook to ReST. This required a few manual fixups and reformats, but the most of contents are kept as is. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-11-10ALSA: doc: ReSTize alsa-driver-api documentTakashi Iwai3-0/+156
A simple conversion of alsa-driver-api document from DocBook to ReST. It's moved to the new Documentation/sound/kernel-api subdirectory that will contain other ALSA kernel API documents. The GPL legal note was removed, as it's superfluous (and doesn't fit with ReST kernel docs pretty well). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-11-10ALSA: doc: Remove alsa-parameters.txtTakashi Iwai1-135/+0

2016-07-26Merge tag 'asoc-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linusTakashi Iwai1-1/+1
ASoC: Updates for v4.8 Not really any framework work this time around (though we have seen one of the Analog Devices drivers move more to the clock API which is good to see) but rather a lot of new drivers: - Lots of updates for the Intel drivers, mostly board support and bug fixing, and to the NAU8825 driver. - Work on generalizing bits of simple-card to allow more code sharing with the Renesas rsrc-card (which can't use simple-card due to DPCM). - Removal of the Odroid X2 driver due to replacement with simple-card. - Support for several new Mediatek platforms and associated boards. - New drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504, Realtek RT5514 and Wolfson WM8758

2015-03-21ALSA: ControlName.txt: Add 'Analogue' as a prefix for volume controlsHoward Mitchell1-5/+5
Currently 'Playback Volume' is the correct way to express an analogue volume control. However, this control name has initialisation defaults applied when using 'alsactl restore' and in some cases this is not appropriate. An example would be a control that has a selection of 0db and -6dB of gain that is intended to set the fullscale ouput voltage of a DAC. The TI pcm512x family of DAcs have such a control. In this case the device/driver reset defaults are preferred. Signed-off-by: Howard Mitchell <hm@hmbedded.co.uk> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-02-20ALSA: core: selection of audio_tstamp type and accuracy reportsPierre-Louis Bossart1-0/+200
Audio timestamps can be extracted from sample counters, wall clocks, PHC clocks (Ethernet AVB), on-demand synchronized snapshots. This patch provides the ability to report timestamping capabilities, select timestamp types and retrieve timestamp accuracy, if supported. Details can be found in Documentations/sound/alsa/timestamping.txt This functionality is introduced by reclaiming the reserved_aligned field introduced by commit9c7066aef4a5eb8e4063de28f06c508bf6f2963a in snd_pcm_status to provide userspace with selection/query capabilities. Additional driver_tstamp and audio_tstamp_accuracy fields are also added. snd_pcm_mmap_status remains a read-only structure with only the audio timestamp value accessible from user space. The selection of audio timestamp type is done through snd_pcm_status only This commit does not impact ABI and does not impact the default behavior. By default audio timestamp is aligned with hw_pointer and reports the DMA position. Backwards compatibility is handled by using the HDAudio wall clock for playback and the hw_ptr for all other cases. For timestamp selection a new STATUS_EXT ioctl is introduced with read/write parameters. Alsa-lib will be modified to make use of STATUS_EXT.

2014-11-04ALSA: pcm: Add xrun_injection proc entryTakashi Iwai1-0/+4
This patch adds a new proc entry for PCM substreams to inject an XRUN. When a PCM substream is running and any value is written to its xrun_injection proc file, the driver triggers XRUN. This is a useful feature for debugging XRUN and error handling code paths. Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is set. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-04ALSA: pcm: Replace PCM hwptr tracking with tracepointsTakashi Iwai1-13/+0
ALSA PCM core has a mechanism tracking the PCM hwptr updates for analyzing XRUNs. But its log is limited (up to 10) and its log output is a kernel message, which is hard to handle. In this patch, the hwptr logging is moved to the tracing infrastructure instead of its own. Not only the hwptr updates but also XRUN and hwptr errors are recorded on the trace log, so that user can see such events at the exact timing. The new "snd_pcm" entry will appear in the tracing events: # ls -F /sys/kernel/debug/tracing/events/snd_pcm enable filter hw_ptr_error/ hwptr/ xrun/ The hwptr is for the regular hwptr update events. An event trace looks like: aplay-26187 [004] d..3 4012.834761: hwptr: pcmC0D0p/sub0: POS: pos=488, old=0, base=0, period=1024, buf=16384 "POS" shows the hwptr update by the explicit position update call and "IRQ" means the hwptr update by the interrupt, i.e. snd_pcm_period_elapsed() call. The "pos" is the passed ring-buffer offset by the caller, "old" is the previous hwptr, "base" is the hwptr base position, "period" and "buf" are period- and buffer-size of the target PCM substream. (Note that the hwptr position displayed here isn't the ring-buffer offset. It increments up to the PCM position boundary.) The XRUN event appears similarly, but without "pos" field. The hwptr error events appear with the PCM identifier and its reason string, such as "Lost interrupt?". The XRUN and hwptr error reports on kernel message are still left, can be turned on/off via xrun_debug proc like before. But the bit 3, 4, 5 and 6 bits of xrun_debug proc are dropped by this patch. Also, along with the change, the message strings have been reformatted to be a bit more consistent. Last but not least, the hwptr reporting is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is set.

2014-06-25ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13Takashi Iwai1-0/+5
HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the default high-pass filter in some "safer" range, which results in the very soft tone from the built-in speakers in contrast to Windows. Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).
