[alsa-devel] Applied "ASoC: stac9766: Move register defines to main source file" to the asoc tree

04 Nov '16

The patch ASoC: stac9766: Move register defines to main source file 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.

This series contains all remaining kernel patches of topology, including some ABI update to PCM (FrontEnds) and link (BackEnds) objects. User will be able to config existing BE DAI links, configure more for FE links. Code are verified and can cover reqeust of Intel pre-release platforms for next year, so ABI should be stable. Current kernel topology code does not really touch Codec-Codec links since there is no user requst atm. We can add support for CC links later by reusing code and data structures for BE links, and no need to revise ABI. History: v2: Add the reason for creating BE DAI & DAI links by topology to commit message. Drop support for configuring DPCM trigger ordering in topology. v3: Topology no longer creates BE DAI or BE DAI links, but only configure existing ones. The API to find a DAI link can also check the name and stream name in case a soc card doesn't use unique ID for DAI links.

[alsa-devel] Applied "ASoC: codecs: msm8916-wcd-analog: clean parse_dt()" to the asoc tree
by Mark Brown 04 Nov '16

04 Nov '16

The patch ASoC: codecs: msm8916-wcd-analog: clean parse_dt() 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] Difference between boundary and buffer_size
by Alan Young 03 Nov '16

03 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.
