[alsa-devel] Difference between boundary and buffer_size
by Alan Young 04 Nov '16

04 Nov '16

The code in the kernel, in /pcm_lib.c/ and /pcm_native.c/, uses fields buffer_size and boundary in struct snd_pcm_runtime. As far as I can see, there are always initialized to the same value. In what circumstance might they be different? There is clearly some relationship to hw_ptr_base, as illustrated by this repeated snipped from snd_pcm_update_hw_ptr0() hw_base += runtime->buffer_size; if (hw_base >= runtime->boundary) { hw_base = 0; crossed_boundary++; } new_hw_ptr = hw_base + pos; Alan.

[alsa-devel] Applied "ASoC: sun4i-i2s: Implement capture support" to the asoc tree
by Mark Brown 03 Nov '16

03 Nov '16

The patch ASoC: sun4i-i2s: Implement capture support 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 v2 0/9] ASoC: Intel: Skylake: Add support for D0i3
by Vinod Koul 03 Nov '16

03 Nov '16

This series adds support for low power D0i3 mode which lets audio controller perform stream and non streaming usage scenarios while being in lower power D0i3 state. In this series, first we modify the sst_ipc_tx_message() API to check if the DSP is in lower powered D0i3 mode or not and if so bring it to active before sending any messages. This is followed by a new API sst_ipc_tx_message_nopm() to send message without checking the new PM method. Then we start adding D0i3 refcounting which decides the entry to D0i3 mode based on capability. This is derived from topology data. The new IPC to enter D0i3 is also required. Finally we remove unwarranted pci device enabling calls on suspend. Changes in v2: - update changelogs - remove patch 1 already applied Jayachandran B (3): ASoC: Intel: Skylake: Add D0iX callbacks ASoC: Intel: Skylake: Flush pending D0i3 request on suspend ASoC: Intel: Skylake: remove pci device enabling calls on suspend Pardha Saradhi K (2): ASoC: Intel: Skylake: Add D0iX IPCs ASoC: Intel: Skylake: Add support for programming D0i3C Vinod Koul (4): ASoC: Intel: Add sst_ipc_tx_message_nopm ASoC: Intel: Skylake: Add support for LPMode ASoC: Intel: Skylake: Add support for specifying D0i3 configuration ASoC: Intel: Skylake: Add D0i3 mode ref counting include/uapi/sound/snd_sst_tokens.h | 8 +- sound/soc/intel/common/sst-ipc.c | 8 ++ sound/soc/intel/common/sst-ipc.h | 3 + sound/soc/intel/skylake/bxt-sst.c | 145 +++++++++++++++++++++++++++++++++ sound/soc/intel/skylake/skl-messages.c | 30 ++++++- sound/soc/intel/skylake/skl-pcm.c | 10 +++ sound/soc/intel/skylake/skl-sst-dsp.h | 12 +++ sound/soc/intel/skylake/skl-sst-ipc.c | 69 +++++++++++++++- sound/soc/intel/skylake/skl-sst-ipc.h | 36 +++++++- sound/soc/intel/skylake/skl-topology.c | 47 +++++++++++ sound/soc/intel/skylake/skl-topology.h | 11 +++ sound/soc/intel/skylake/skl.c | 59 +++++++++++++- sound/soc/intel/skylake/skl.h | 6 ++ 13 files changed, 437 insertions(+), 7 deletions(-) -- 1.9.1
