[alsa-devel] [PATCH] ALSA: usb-audio: Check mixer unit bitmap yet more strictly
by Takashi Iwai 22 Aug '19

22 Aug '19

The bmControls (for UAC1) or bmMixerControls (for UAC2/3) bitmap has a variable size depending on both input and output pins. Its size is to fit with input * output bits. The problem is that the input size can't be determined simply from the unit descriptor itself but it needs to parse the whole connected sources. Although the uac_mixer_unit_get_channels() tries to check some possible overflow of this bitmap, it's incomplete due to the lack of the evaluation of input pins. For covering possible overflows, this patch adds the bitmap overflow check in the loop of input pins in parse_audio_mixer_unit().

[alsa-devel] [RFC PATCH 00/11] soundwire: intel: simplify DAI/PDI handling
by Pierre-Louis Bossart 21 Aug '19

21 Aug '19

In the initial SoundWire code released by Intel, the PDIs and ports on the Master interface were dynamically allocated. This wasn't a bad idea at the time and would have allowed for interesting routing. Fast-forward to 2019, with the hardware available on CometLake/IceLake, that dynamic allocation makes it complicated to deal with statically-allocated ASoC dailinks and topology-defined DAIs. In this series, we suggest a drastic simplification where the SoundWire code reuses information provided by DAIs and dailinks. We also suggest removing the dynamic allocation of ports on the master since in practice there is a 1:1 mapping between ports and PDIs. In the second part of the series, we suggest adding new callbacks to SoundWire DAIs, so that all the SoundWire stream operations are contained at the DAI level. This solution results in a very simple integration with the SOF code (which will be shared in a separate series since SOF will not apply directly on top of soundwire/next). The SOF parts only call a SoundWire init/release API, and provides 2 callbacks for hw_params and free, with all the details of the SoundWire DAIs and IP handled in drivers/soundwire. This solution has been tested on CometLake/IceLake with simple capture/playback. When ASoC supports the multi-cpu capability needed for synchronized playback/capture across multiple links, we will have to modify slightly this solution so that the stream alloc, release and trigger operations are done once. This is future work that will take place later, likely after 5.4, and which should not impact the SOF integration. The code in this patchset is the result of collaboration between Bard Liao, Rander Wang and Pierre Bossart, with ideas coming from all 3 sides. It's likely that there are still some parts in the code that can be improved, hence the RFC state.

[alsa-devel] [PATCH v5 00/15] ASoC: sun4i-i2s: Updates to the driver
by codekipper＠gmail.com 21 Aug '19

21 Aug '19

From: Marcus Cooper <codekipper(a)gmail.com> Hi All, here is a patch series to add some improvements to the sun4i-i2s driver found whilst getting slave clocking and hdmi audio working on the newer SoCs. As the LibreELEC project is progressing extremely well then there has been some activity getting H6 SoC support with surround sound working and these changes are also included. The functionality included with the new patch set has been extended to cover more sample resolutions, multi-lane data output for HDMI audio and some bug fixes that have been discovered along the way. I have changed some of the original reg fields into function calls as this made it easier to setup for multi-channel audio especially across different SoCs. I can see more usage of the tdm property since I last attempted to push these patches and the examples currently in mainline sort of the opposite to what I'm trying to achieve. When we first started looking at the i2s driver, the codecs that we were using allowed for the frame width to be determined based on the sampling resolution but in most use cases it seems that a fixed width is required(my highest priority should be to get HDMI audio support in). We're using the tdm property to override the old way to calculate the frame width. What I've seen in what has already been mainlined is that the i2s driver has a frame width that is fixed to 32 bits and this can be overridden using the tdm property. My test branch for this can be found at https://github.com/codekipper/linux-sunxi/commits/upstream-i2s , I've been using a Pine64 to test with; validating the new SoC block with HDMI audio and ensuring that I've not broken the old block by making sure that the audio codec still works. If we able to get the first three patches delivered then that is enough for HDMI audio support on the newer SoCs(H3, A64 etc). I still need to investigate the FIFO syncing issues which i've not had a chance to change or address the concerns that broonie and wens brought up. This change has been moved to the top of the patch stack. I would also like to make the multi-channel audio and audio mapping more configurable via the device tree. Currently what is implemented suites our current needs. BR, CK --- v5 changes compared to v4 are: - removed delivered patches. - Added more details to commit messages. - replaced some reg fields with function calls. - Added DSP_A and DSP_B support for H3 and later SoCs. - Added support for the Allwinner H6. v4 changes compared to v3 are: - Moved patches around so that the more controversial of patches are at the top of the stack. - Added more details to commit messages. - Fixed 20bit audio PCM format to use 4 bytes. - Reduced number of flags used to indicate a new SoC. v3 changes compared to v2 are: - added back slave mode changes - added back the use of tdm properties - changes to regmap and caching - removed loopback functionality - fixes to the channel offset mask v2 changes compared to v1 are: - removed slave mode changes which didn't set mclk and bclk div. - removed use of tdm and now use a dedicated property. - fix commit message to better explain reason for sign extending - add divider calculations for newer SoCs. - add support for multi-lane i2s data output. - add support for 20, 24 and 32 bit samples. - add loopback property so blocks can be tested without a codec. --- Jernej Skrabec (3): clk: sunxi-ng: h6: Allow I2S to change parent rate dt-bindings: ASoC: sun4i-i2s: Add H6 compatible ASoC: sun4i-i2s: Add support for H6 I2S Marcus Cooper (12): ASoC: sun4i-i2s: Add regmap field to sign extend sample ASoC: sun4i-i2s: Add set_tdm_slot functionality ASoC: sun4i-i2s: Correct divider calculations ASoC: sun4i-i2s: Support more formats on newer SoCs ASoC: sun4i-i2s: Add functions for RX and TX channel offsets ASoC: sun4i-i2s: Add functions for RX and TX channel enables ASoC: sun4i-i2s: Add functions for RX and TX channel selects ASoC: sun4i-i2s: Add functions for channel mapping ASoC: sun4i-i2s: Add multi-lane functionality ASoC: sun4i-i2s: Add multichannel functionality ASoc: sun4i-i2s: Add 20, 24 and 32 bit support ASoC: sun4i-i2s: Adjust regmap settings .../sound/allwinner,sun4i-a10-i2s.yaml | 2 + drivers/clk/sunxi-ng/ccu-sun50i-h6.c | 8 +- sound/soc/sunxi/sun4i-i2s.c | 690 ++++++++++++++---- 3 files changed, 542 insertions(+), 158 deletions(-) -- 2.22.0
