[alsa-devel] [PATCH 00/55] ALSA: Support PCM sync_stop
by Takashi Iwai 10 Dec '19

10 Dec '19

Hi, this is the last episode of the trilogy of PCM enhancements for non-ASoC drivers. Basically this either adds the setup for card->sync_irq and removes the superfluous synchronize_irq() calls, or replaces the synchronization code with the new sync_irq PCM ops. For the explanation about PCM ssync_stop and card sync_irq, see the commits: 1e850beea2781d30418743dd99250291cef37919 ALSA: pcm: Add the support for sync-stop operation fabb26dcd104027b971c018275fe40f2ebe09ae3 ALSA: pcm: Add card sync_irq field thanks, Takashi === Takashi Iwai (55): ALSA: ad1889: Support PCM sync_stop ALSA: ali5451: Support PCM sync_stop ALSA: als300: Support PCM sync_stop ALSA: atiixp: Support PCM sync_stop ALSA: au88x0: Support PCM sync_stop ALSA: aw2: Support PCM sync_stop ALSA: azt3328: Support PCM sync_stop ALSA: bt87x: Support PCM sync_stop ALSA: ca0106: Support PCM sync_stop ALSA: cmipci: Support PCM sync_stop ALSA: cs4281: Support PCM sync_stop ALSA: cs46xx: Support PCM sync_stop ALSA: cs5535audio: Support PCM sync_stop ALSA: ctxfi: Support PCM sync_stop ALSA: echoaudio: Support PCM sync_stop ALSA: emu10k1: Support PCM sync_stop ALSA: ens137x: Support PCM sync_stop ALSA: es1938: Support PCM sync_stop ALSA: es1968: Support PCM sync_stop ALSA: fm801: Support PCM sync_stop ALSA: hda: Support PCM sync_stop ALSA: ice1712: Support PCM sync_stop ALSA: ice1724: Support PCM sync_stop ALSA: intel8x0: Support PCM sync_stop ALSA: korg1212: Support PCM sync_stop ALSA: lola: Support PCM sync_stop ALSA: maestro3: Support PCM sync_stop ALSA: nm256: Support PCM sync_stop ALSA: oxygen: Support PCM sync_stop ALSA: riptide: Support PCM sync_stop ALSA: rme32: Support PCM sync_stop ALSA: rme96: Support PCM sync_stop ALSA: rme9652: Support PCM sync_stop ALSA: sis7019: Support PCM sync_stop ALSA: sonicvibes: Support PCM sync_stop ALSA: trident: Support PCM sync_stop ALSA: via82xx: Support PCM sync_stop ALSA: ymfpci: Support PCM sync_stop ALSA: ad1816a: Support PCM sync_stop ALSA: es1688: Support PCM sync_stop ALSA: es18xx: Support PCM sync_stop ALSA: gus: Support PCM sync_stop ALSA: msnd: Support PCM sync_stop ALSA: opl3sa2: Support PCM sync_stop ALSA: opti9xx: Support PCM sync_stop ALSA: sb: Support PCM sync_stop ALSA: wavefront: Support PCM sync_stop ALSA: wss: Support PCM sync_stop ALSA: lx6464es: Support PCM sync_stop ALSA: mixart: Support PCM sync_stop ALSA: pcxhr: Support PCM sync_stop ALSA: vx222: Support PCM sync_stop ALSA: pdaudiocf: Support PCM sync_stop ALSA: vxpocket: Support PCM sync_stop ALSA: usb-audio: Support PCM sync_stop sound/isa/ad1816a/ad1816a_lib.c | 1 + sound/isa/es1688/es1688_lib.c | 1 + sound/isa/es18xx.c | 1 + sound/isa/gus/gus_main.c | 1 + sound/isa/gus/gusmax.c | 3 ++- sound/isa/gus/interwave.c | 1 + sound/isa/msnd/msnd_pinnacle.c | 1 + sound/isa/opl3sa2.c | 1 + sound/isa/opti9xx/opti92x-ad1848.c | 1 + sound/isa/sb/sb_common.c | 1 + sound/isa/wavefront/wavefront.c | 1 + sound/isa/wss/wss_lib.c | 1 + sound/pci/ad1889.c | 2 +- sound/pci/ali5451/ali5451.c | 3 +-- sound/pci/als300.c | 2 +- sound/pci/atiixp.c | 2 +- sound/pci/atiixp_modem.c | 2 +- sound/pci/au88x0/au88x0.c | 1 + sound/pci/aw2/aw2-alsa.c | 1 + sound/pci/azt3328.c | 2 +- sound/pci/bt87x.c | 2 +- sound/pci/ca0106/ca0106_main.c | 1 + sound/pci/cmipci.c | 1 + sound/pci/cs4281.c | 5 +---- sound/pci/cs46xx/cs46xx_lib.c | 1 + sound/pci/cs5535audio/cs5535audio.c | 2 +- sound/pci/ctxfi/cthw20k1.c | 4 +--- sound/pci/ctxfi/cthw20k2.c | 1 + sound/pci/echoaudio/echoaudio.c | 3 +++ sound/pci/emu10k1/emu10k1_main.c | 1 + sound/pci/emu10k1/emu10k1x.c | 1 + sound/pci/ens1370.c | 4 +--- sound/pci/es1938.c | 3 +++ sound/pci/es1968.c | 3 +-- sound/pci/fm801.c | 1 + sound/pci/hda/hda_intel.c | 4 +++- sound/pci/hda/hda_tegra.c | 4 +--- sound/pci/ice1712/ice1712.c | 2 +- sound/pci/ice1712/ice1724.c | 2 +- sound/pci/intel8x0.c | 4 +++- sound/pci/intel8x0m.c | 3 +++ sound/pci/korg1212/korg1212.c | 1 + sound/pci/lola/lola.c | 2 +- sound/pci/lx6464es/lx6464es.c | 1 + sound/pci/maestro3.c | 1 + sound/pci/mixart/mixart.c | 1 + sound/pci/nm256/nm256.c | 2 ++ sound/pci/oxygen/oxygen_lib.c | 2 +- sound/pci/pcxhr/pcxhr.c | 1 + sound/pci/riptide/riptide.c | 1 + sound/pci/rme32.c | 1 + sound/pci/rme96.c | 1 + sound/pci/rme9652/hdsp.c | 1 + sound/pci/rme9652/hdspm.c | 1 + sound/pci/rme9652/rme9652.c | 1 + sound/pci/sis7019.c | 1 + sound/pci/sonicvibes.c | 1 + sound/pci/trident/trident_main.c | 1 + sound/pci/via82xx.c | 3 +-- sound/pci/via82xx_modem.c | 3 +-- sound/pci/vx222/vx222.c | 1 + sound/pci/ymfpci/ymfpci_main.c | 1 + sound/pcmcia/pdaudiocf/pdaudiocf.c | 1 + sound/pcmcia/vx/vxpocket.c | 1 + sound/usb/pcm.c | 37 +++++++++++++++++++++++++------------ 65 files changed, 101 insertions(+), 47 deletions(-) -- 2.16.4

Right, I meant extern1 the parent of clk_out_1, sorry for the confusion. So when clk_out_1 (child) is enabled, extern1 (parent) is enabled as well. I'll take a closer look at the other email tomorrow.

[alsa-devel] [PATCH] ASoC: core: only flush inited work during free
by Curtis Malainey 09 Dec '19

09 Dec '19

There are many paths to soc_free_pcm_runtime which can both have and have not yet inited the workqueue yet. When we flush the queue when we have not yet inited the queue we cause warnings to be printed. An example is soc_cleanup_card_resources which is called by snd_soc_bind_card which has multiple failure points before and after soc_link_init -> soc_new_pcm which is where the queue is inited.

[alsa-devel] [PATCH 0/3] ASoC: Intel: SOF: use common HDMI driver
by Pierre-Louis Bossart 09 Dec '19

09 Dec '19

By default make sure all SOF-based solutions use the common HDMI driver. The hdac_hdmi solution is only supported for devices based on the SST driver. This change was merged two weeks ago in the SOF tree and no regressions were observed.
