Hi Takashi, Today's linux-next merge of the sound tree got a conflict in sound/pci/hda/hda_intel.c between commit 246efa4a072f ("snd/hda: add runtime suspend/resume on optimus support (v4)") from the drm tree and commit 7d4f606c50ff ("ALSA: hda - WAKEEN feature enabling for runtime pm") from the sound tree. I fixed it up (see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc sound/pci/hda/hda_intel.c index bf5e58e,c6c9829..0000000 --- a/sound/pci/hda/hda_intel.c +++ b/sound/pci/hda/hda_intel.c @@@ -2975,12 -2971,10 +2975,16 @@@ static int azx_runtime_suspend(struct d struct snd_card *card = dev_get_drvdata(dev); struct azx *chip = card->private_data; + if (chip->disabled) + return 0; + + if (!(chip->driver_caps & AZX_DCAPS_PM_RUNTIME)) + return 0; + + /* enable controller wake up event */ + azx_writew(chip, WAKEEN, azx_readw(chip, WAKEEN) | + STATESTS_INT_MASK); + azx_stop_chip(chip); azx_enter_link_reset(chip); azx_clear_irq_pending(chip); @@@ -2993,17 -2987,31 +2997,37 @@@ static int azx_runtime_resume(struct de { struct snd_card *card = dev_get_drvdata(dev); struct azx *chip = card->private_data; + struct hda_bus *bus; + struct hda_codec *codec; + int status; + if (chip->disabled) + return 0; + + if (!(chip->driver_caps & AZX_DCAPS_PM_RUNTIME)) + return 0; + if (chip->driver_caps & AZX_DCAPS_I915_POWERWELL) hda_display_power(true); + + /* Read STATESTS before controller reset */ + status = azx_readw(chip, STATESTS); + azx_init_pci(chip); azx_init_chip(chip, 1); + + bus = chip->bus; + if (status && bus) { + list_for_each_entry(codec, &bus->codec_list, list) + if (status & (1 << codec->addr)) + queue_delayed_work(codec->bus->workq, + &codec->jackpoll_work, codec->jackpoll_interval); + } + + /* disable controller Wake Up event*/ + azx_writew(chip, WAKEEN, azx_readw(chip, WAKEEN) & + ~STATESTS_INT_MASK); + return 0; }
