* pcm: hw: fix the silence size setup in drainJaroslav Kysela2023-05-031-2/+2
| | | | | | | | | The silence size cannot exceed the silence threshold. Move the check from the manual condition to the common code. This may happen for small ring buffers (where the 1/10th second is too large). Suggested-by: Oswald Buddenhagen <oswald.buddenhagen@gmx.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

* pcm: improve handling for snd_pcm_wait()Jaroslav Kysela2023-05-039-10/+55
| | | | | | | | | | | | | The snd_pcm_wait() function is called also internally from the various plugins to wait for the drain with -1 and from i/o routines in pcm.c. Define two special negative timeout values to distinguish the drain and i/o wait and calculate the maximal timeout according the wait place.

* pcm: hw: introduce SNDRV_PCM_HW_PARAMS_DRAIN_SILENCEJaroslav Kysela2023-05-035-1/+45
| | | | | | | | | | The application may not require to touch the playback sample stream for the drain operation at all. In this case, the application is responsible to setup a silencing mechanism for the playback or another graceful stop (like using the rewind operation). Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* pcm: hw: introduce SNDRV_PCM_INFO_PERFECT_DRAINJaroslav Kysela2023-05-035-1/+30
| | | | | | | | | Handle the driver informing us that it is not necessary to set up silencing upon playback draining. This will be the case for drivers which are guaranteed to not read any samples beyond the application pointer. Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* pcm: hw: add drain_silence configuration keywordJaroslav Kysela2023-05-031-2/+24
| | | | | | | # Add silence in drain (-1 = auto /default/, 0 = off, > 0 milliseconds) [drain_silence INT] Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* pcm: hw: setup explicit silencing for snd_pcm_drain by defaultJaroslav Kysela2023-05-033-13/+71
| | | | | | | | | | | | | Some applications may not alignt transfers to the period size and also the driver developers may not follow the consequeces of the access beyond valid samples in the playback DMA buffer. To avoid clicks, fill a little silence at the end of the playback ring buffer when snd_pcm_drain() is called.

| | | | | | | | | | snd_soc_tplg_dapm_widget has ignore_suspend field, but there is no way to set value for it, because we don't parse topology field for it. Fix this by adding parsing code.

* ucm: add existence checks to geti callsCurtis Malainey2023-01-151-16/+67
| | | | | | | | | | | | | | Right now in snd_use_case_geti you cannot tell if the item being queried exists or not when being checked. This also means the only way to check for the existence of something in the client of the library is to iterate over the list of mods/devs even if we know exactly the name we are looking for. We have functions that do exactly this internally so lets return this information in a logical fashion through geti. Also clean up some trailing white space nearby.
