[alsa-devel] [PATCH 176/182] ASoC: rt5677: use gpiochip data pointer
by Linus Walleij 12 Dec '15

12 Dec '15

This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of().

[alsa-devel] [PATCH v2 00/13] ASoC: Intel: Skylake: Update to SKL driver
by Vinod Koul 12 Dec '15

12 Dec '15

This update bring in new APIs in core and usage of those in SKL driver. The series is broadly of three parts - first two are fixes on the driver - then we add DMA resume capability in HDA core and use it to save restore DMA link values and add DMA resume capability in driver - lastly, we add support for MISCBDCGE configuration in core and use it while resetting and also for phrase detection per HW recommendation This should be merged thru ASoC tree due to obvious dependencies. Takashi would need your ack on core patches changes in v2: - move msicbdge api to driver and as a consequence sqash into into first use - fix lkp warning Dharageswari.R (1): ASoC: Intel: Skylake: Use CGCTL.MISCBDCGE for Phrase detection notification Jayachandran B (2): ALSA: hdac: Increase timeout value for link power check ASoC: Intel: Skylake: fix reset controller sequencing Jeeja KP (8): ASoC: Intel: Skylake: Clear stream registers before stream setup ASoC: Intel: Skylake: Fix to set pipe state to invalid when deleting ALSA: hdac: Add support for hda DMA Resume capability ALSA: hdac: couple the hda DMA stream in cleanup ASoC: Intel: Skylake: enable interrupt as wake source in active suspend ASoC: Intel: Skylake: Add DMA resume position in Trigger resume/suspend ASoC: Intel: Skylake: Reconfigure Link stream on suspend/resume ASoC: Intel: Skylake: Add Resume capability in PCM info.

[alsa-devel] [PATCH v2] ASoC: fsl_sai: fix no frame clk in master mode
by Zidan Wang 12 Dec '15

12 Dec '15

After several open/close sai test with ctrl+c, there will be I/O error. The SAI can't work anymore, can't recover. There will be no frame clock. With adding the software reset in trigger stop, the issue can be fixed. This is a hardware bug/errata and reset is the only option. According to the reference manual, the software reset doesn't reset any control register but only internal hardware logics such as bit clock generator, status flags, and FIFO pointers. (Our purpose is just to reset the clock generator while the software reset is the only way to do that.) Since slave mode doesn't use the clock generator, only apply the reset procedure to the master mode. For asynchronous mode, TX will not be reset when RX is still running. In this case, i can't reproduce this issue. Signed-off-by: Zidan Wang <zidan.wang(a)freescale.com> --- v1->v2: 1) refine the commit log and comments 2) Since slave mode doesn't use the clock generator, only apply the reset procedure to the master mode. sound/soc/fsl/fsl_sai.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/sound/soc/fsl/fsl_sai.c b/sound/soc/fsl/fsl_sai.c index 8832901..a55a7de 100644 --- a/sound/soc/fsl/fsl_sai.c +++ b/sound/soc/fsl/fsl_sai.c @@ -564,6 +564,17 @@ static int fsl_sai_trigger(struct snd_pcm_substream *substream, int cmd, FSL_SAI_CSR_FR, FSL_SAI_CSR_FR); regmap_update_bits(sai->regmap, FSL_SAI_RCSR, FSL_SAI_CSR_FR, FSL_SAI_CSR_FR); + + if (!sai->is_slave_mode) { + /* Software Reset for both Tx and Rx */ + regmap_write(sai->regmap, + FSL_SAI_TCSR, FSL_SAI_CSR_SR); + regmap_write(sai->regmap, + FSL_SAI_RCSR, FSL_SAI_CSR_SR); + /* Clear SR bit to finish the reset */ + regmap_write(sai->regmap, FSL_SAI_TCSR, 0); + regmap_write(sai->regmap, FSL_SAI_RCSR, 0); + } } break; default: -- 1.9.1

[alsa-devel] Available frames > buffer size
by Rob Duncan 11 Dec '15

11 Dec '15

Is it ever correct for snd_pcm_avail() to return a value that’s greater than that returned by snd_pcm_hw_params_get_buffer_size()? I’m trying to track down some unexpected underruns in my application and I notice that when they occur I also see that the available frames count is wrong. For example here are a couple of lines from my logging: 2015-12-08T23:17:23.118817-08:00 X ? 2080 + 2080 2015-12-08T23:17:23.119524-08:00 X = 2080 ? 4126 The first log line: here I asked the device how many frames are available and it responds with 2080; I accordingly write 2080 frames. The second log line: the writei() call returns 2080. I immediately ask how many frames are available now (I usually get a small number in response ~ 20-30) but this time I get an XRUN. I call snd_pcm_recover() and then snd_pcm_avail() again and now I get 4126 frames. As you can see the time between these two logs is less than 1 millisecond, so I don’t understand how the PCM can go from 2080 frames available to >4096 frames available so quickly. Is this evidence of a bug in the device driver? My application is using a single channel dshare PCM (rt) that has an 8-channel device underneath. Here’s the configuration fragment: pcm_slave.cid_dsp { pcm "hw:0,0" channels 8 rate 44100 } pcm.rt_channel { type dshare ipc_key 1025 ipc_gid audio ipc_perm 0660 slave cid_dsp bindings { 0 5 } } pcm.rt { type plug slave.pcm rt_channel } The underlying hardware looks like this: access: MMAP_INTERLEAVED format: S16_LE subformat: STD channels: 8 rate: 44100 (44100/1) period_size: 1024 buffer_size: 4096 tstamp_mode: ENABLE period_step: 1 avail_min: 1 start_threshold: 1 stop_threshold: 1073741824 silence_threshold: 0 silence_size: 0 boundary: 1073741824 Thanks for any insight and help, Rob.

[alsa-devel] [PATCH v5] sun4i-codec: add inputs
by Danny Milosavljevic 11 Dec '15

11 Dec '15

Hi, this is the fifth version of the patch that adds inputs to sun4i-codec. (Previous versions have been on the linux-sunxi mailing list only) The inputs added are: - FM-In Left and Right - Line-In Left and Right - Mic1-In - Mic2-In Changes compared to v4 are: - Mic preamplifier controls have more common names now. - Mic preamplifier scale has a 0 dB entry as well now, as documented in the A20 user manual. - Mic preamplifier has special cases for A20 and A10 now. - Gain controls have "Gain" in the name now. I successfully tested it on an A20 board using alsamixer, headphones, a radio and my ears. Note that because of missing capturing support I tested only the mixing, for Mic, Line, and FM. The patches are on top of <git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git>, branch "sunxi/for-next".
