[alsa-devel] [PATCH v2 0/2] Add snd_card_disconnect_sync() helper
by Takashi Iwai 18 Oct '17

18 Oct '17

Hi, here is a refreshed series containing ALSA core changes Morimoto-san posted. Basically the code is same but it's split, and more comments and an error message are added. I tested lightly with the existing hot-pluggable device and no regression was seen. The commits are found in topic/card-disconnect branch of sound git tree, too. Mark, please pull it to yours when applying the further patches relying on this new helper function. thanks, Takashi === Takashi Iwai (2): ALSA: add snd_card_disconnect_sync() ALSA: pcm: Forcibly stop at disconnect callback include/sound/core.h | 2 ++ sound/core/init.c | 32 ++++++++++++++++++++++++++++++++ sound/core/pcm.c | 4 ++++ 3 files changed, 38 insertions(+) -- 2.14.2

[alsa-devel] [PATCH] ALSA: seq: Enable 'use' locking in all configurations
by Ben Hutchings 18 Oct '17

18 Oct '17

The 'use' locking macros are no-ops if neither SMP or SND_DEBUG is enabled. This might once have been OK in non-preemptible configurations, but even in that case snd_seq_read() may sleep while relying on a 'use' lock. So always use the proper implementations.

[alsa-devel] Applied "drm/amd/amdgpu: Added asic_type as ACP DMA driver platform data" to the asoc tree

The patch drm/amd/amdgpu: Added asic_type as ACP DMA driver platform data has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[alsa-devel] [PATCH 0/9 v2] Add ASoC support for AMD Stoney APUs
by Alex Deucher 18 Oct '17

18 Oct '17

This patch set updates the AMD GPU and Audio CoProcessor (ACP) audio drivers and the designware i2s driver for Stoney (ST). ST is an APU similar to Carrizo (CZ) which already has ACP audio support. The i2s controller and ACP audio DMA engine are part of the GPU and both need updating so I would like to upstream the whole patch set via one tree if possible. The current code is based on drm-next, but I'm happy to rebase on whatever tree this ends up going through if there are any problems applying.
