[PATCH] ALSA: compress: allow pause and resume during draining
by Gyeongtaek Lee 01 Oct '20

01 Oct '20

With a stream with low bitrate, user can't pause or resume the stream near the end of the stream because current ALSA doesn't allow it. If the stream has very low bitrate enough to store whole stream into the buffer, user can't do anything except stop the stream and then restart it from the first. If pause and resume is allowed during draining, user experience can be enhanced.

[PATCH v2 0/7][RESEND] ASoC: merge soc_pcm_open() rollback and soc_pcm_close()

Hi Mark 1 month past and nothing happened. This is resend of v2 patch-set. soc_pcm_open() does rollback when failed (A), but, it is almost same as soc_pcm_close(). static int soc_pcm_open(xxx) { ... if (ret < 0) goto xxx_err; ... return 0; ^ config_err: | ... | rtd_startup_err: (A) ... | component_err: | ... v return ret; } This kind of duplicated code can be a hotbed of bugs, thus, this patch-set share soc_pcm_close() and rollback. v1 -> v2 - indicate more detail background/logic on git-log Link: https://lore.kernel.org/r/87wo2oku0m.wl-kuninori.morimoto.gx@renesas.com Link: https://lore.kernel.org/r/87wo1kvozz.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (7): ASoC: soc-dai: add mark for snd_soc_dai_startup/shutdown() ASoC: soc-link: add mark for snd_soc_link_startup/shutdown() ASoC: soc-component: add mark for soc_pcm_components_open/close() ASoC: soc-component: add mark for snd_soc_pcm_component_pm_runtime_get/put() ASoC: soc-pcm: add soc_pcm_clean() and call it from soc_pcm_open/close() ASoC: soc-pcm: remove unneeded dev_err() for snd_soc_dai_startup() ASoC: soc-pcm: remove unneeded dev_err() for snd_soc_component_module/open() include/sound/soc-component.h | 28 +++++--- include/sound/soc-dai.h | 5 +- include/sound/soc-link.h | 3 +- include/sound/soc.h | 3 + sound/soc/soc-component.c | 73 ++++++++++++++++++++- sound/soc/soc-compress.c | 30 +++------ sound/soc/soc-dai.c | 21 +++++- sound/soc/soc-dapm.c | 4 +- sound/soc/soc-link.c | 21 +++++- sound/soc/soc-pcm.c | 120 ++++++++++++---------------------- 10 files changed, 190 insertions(+), 118 deletions(-) -- 2.25.1
