[alsa-devel] pyalsa support for Python 3
by Maurizio Berti 13 Feb '18

13 Feb '18

Hello, I used pyalsa's alsaseq module for a project of mine which used Python 2. Now I'm switching to Python 3 and I'd need to use the alsaseq module with that version. Unfortunally, it seems that Python 3 support has not been added yet. I found this message: http://linux-audio.4202.n7.nabble.com/Python3-PyAlsa-Build-fails-td83590.ht… It is older than the latest release of pyalsa, but, even after trying to follow the instructions, I still get errors and cannot build pyalsa for Python3: while the "pyalsa/alsacontrol.c:184:6: error: ‘struct pyalsacontrol’ has no member named ‘ob_type’" error is gone, it still doesn't build. The latest message reports: error: command 'i686-pc-linux-gnu-gcc' failed with exit status 1 Is there any chance that pyalsa gets an update for it? Thank you, Maurizio -- È difficile avere una convinzione precisa quando si parla delle ragioni del cuore. - "Sostiene Pereira", Antonio Tabucchi http://www.jidesk.net

[alsa-devel] [PATCH v2 0/9] add UniPhier audio system support
by Katsuhiro Suzuki 13 Feb '18

13 Feb '18

This series adds support for Socionext audio system for UniPhier LD11/LD20 SoCs. This driver supports I2S output for Line-In, Line-Out and S/PDIF output. UniPhier AIO DAI driver provides sound devices such as I2S, S/PDIF. Since the AIO has mixed register map for those I/Os, it is hard to split register areas for each sound devices. --- Changes in v2: - Add comments to aiodma_irq() - Add members to struct uniphier_aio_sub and add methods for compress audio - Expose clocking to userspace - Fix bad name 'srcport' to 'src' - Split DMA, DAI patches from large one - Validate parameters in hw_params() - Add error checks - Fix typo in error messages - Change license comment style to C++ from C Katsuhiro Suzuki (9): ASoC: uniphier: add DT bindings documentation for UniPhier AIO ASoC: uniphier: add support for UniPhier AIO common driver ASoC: uniphier: add support for UniPhier AIO DMA driver ASoC: uniphier: add support for UniPhier AIO CPU DAI driver ASoC: uniphier: add support for UniPhier AIO compress audio ASoC: uniphier: add support for UniPhier LD11/LD20 AIO driver arm64: dts: uniphier: add sound node for UniPhier arm64: dts: uniphier: add speaker out for UniPhier LD11/LD20 boards arm64: dts: uniphier: add compress audio out for UniPhier LD11/LD20 .../devicetree/bindings/sound/uniphier,aio.txt | 36 + .../boot/dts/socionext/uniphier-ld11-global.dts | 120 +++ arch/arm64/boot/dts/socionext/uniphier-ld11.dtsi | 31 + .../boot/dts/socionext/uniphier-ld20-global.dts | 120 +++ arch/arm64/boot/dts/socionext/uniphier-ld20.dtsi | 35 + sound/soc/uniphier/Kconfig | 22 + sound/soc/uniphier/Makefile | 6 + sound/soc/uniphier/aio-compress.c | 440 ++++++++ sound/soc/uniphier/aio-core.c | 1104 ++++++++++++++++++++ sound/soc/uniphier/aio-cpu.c | 570 ++++++++++ sound/soc/uniphier/aio-dma.c | 318 ++++++ sound/soc/uniphier/aio-ld11.c | 431 ++++++++ sound/soc/uniphier/aio-reg.h | 462 ++++++++ sound/soc/uniphier/aio.h | 355 +++++++ 14 files changed, 4050 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/uniphier,aio.txt create mode 100644 sound/soc/uniphier/aio-compress.c create mode 100644 sound/soc/uniphier/aio-core.c create mode 100644 sound/soc/uniphier/aio-cpu.c create mode 100644 sound/soc/uniphier/aio-dma.c create mode 100644 sound/soc/uniphier/aio-ld11.c create mode 100644 sound/soc/uniphier/aio-reg.h create mode 100644 sound/soc/uniphier/aio.h -- 2.15.0

[alsa-devel] [PATCH v2 4/5] ALSA: emu10k1: make sure synth DMA pages are allocated with DMA functions
by Maciej S. Szmigiero 13 Feb '18

13 Feb '18

Commit a5003fc04113 ("[ALSA] emu10k1 - simplify page allocation for synth") switched from using the DMA allocator for synth DMA pages to manually calling alloc_page(). However, this usage has an implicit assumption that the DMA address space for the emu10k1-family chip is the same as the CPU physical address space which is not true for a system with a IOMMU. Since this made the synth part of the driver non-functional on such systems let's effectively revert that commit. Signed-off-by: Maciej S.
