[alsa-devel] [PATCH v4 00/13] soundwire: Add stream support
by Vinod Koul 25 Apr '18

25 Apr '18

This series adds support in SoundWire subsystem for: - Documentation for stream support - stream management - data port management - DAI ops in cadence and Intel drivers - ASoC API to propagate SDW stream Updates in v4: - Add more comments for sdw_release_master_stream() - Make sure ports are freed upon sdw_stream_remove_slave() - Clarify snd_soc_dai_set_sdw_stream() and setting of NULL upon release. Updates in v3: - Remove stream state transition checks and redefine stream states - Update bansk switch routines - Other nitpicks pointed out by Pierre. Updates in v2: - Make ASoC API inlined - Make stream states as states and not action - Update the direction enum - Fix some typos and comment updates Sanyog Kale (7): Documentation: soundwire: Add more documentation soundwire: Add support for SoundWire stream management soundwire: Add support for port management soundwire: Add Master and Slave port programming soundwire: Add helpers for ports operations soundwire: Add bank switch routine soundwire: Add stream configuration APIs Shreyas NC (2): ASoC: Add SoundWire stream programming interface soundwire: Remove cdns_master_ops Vinod Koul (4): soundwire: cdns: Add port routines soundwire: cdns: Add stream routines soundwire: intel: Add stream initialization soundwire: intel: Add audio DAI ops .../driver-api/soundwire/error_handling.rst | 65 + Documentation/driver-api/soundwire/index.rst | 3 + Documentation/driver-api/soundwire/locking.rst | 106 ++ Documentation/driver-api/soundwire/stream.rst | 372 +++++ drivers/soundwire/Kconfig | 2 +- drivers/soundwire/Makefile | 2 +- drivers/soundwire/bus.c | 43 + drivers/soundwire/bus.h | 72 + drivers/soundwire/cadence_master.c | 453 +++++- drivers/soundwire/cadence_master.h | 151 ++ drivers/soundwire/intel.c | 528 ++++++- drivers/soundwire/intel.h | 4 + drivers/soundwire/intel_init.c | 3 + drivers/soundwire/stream.c | 1480 ++++++++++++++++++++ include/linux/soundwire/sdw.h | 332 ++++- include/linux/soundwire/sdw_intel.h | 14 + include/sound/soc-dai.h | 23 + 17 files changed, 3639 insertions(+), 14 deletions(-) create mode 100644 Documentation/driver-api/soundwire/error_handling.rst create mode 100644 Documentation/driver-api/soundwire/locking.rst create mode 100644 Documentation/driver-api/soundwire/stream.rst create mode 100644 drivers/soundwire/stream.c -- 2.7.4

[alsa-devel] [PATCH] ALSA: hda - Skip jack and others for non-existing PCM streams
by Takashi Iwai 25 Apr '18

25 Apr '18

When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited number of devices available, and HD-audio, especially with HDMI/DP codec, will fail to create more than two devices. The driver warns about the lack of such devices and skips the PCM device creations, but the HDMI driver still tries to create the corresponding JACK, SPDIF and ELD controls even for the non-existing PCM substreams. This results in confusion on user-space, and even may break the operation. Similarly, Intel HDMI/DP codec builds the ELD notification from i915 graphics driver, and this may be broken if a notification is sent for the non-existing PCM stream. This patch adds the check of the existence of the assigned PCM substream in the both scenarios above, and skips the further operation if the PCM substream is not assigned.

[alsa-devel] ASoC: BCM2835-I2S: TDM slots / slot mask ignored
by Steven Eckhoff 25 Apr '18

25 Apr '18

Hi, I am testing a codec driver interfaced to the Raspberry Pi in TDM mode and on the logic analyzer I see that the I2S controller is shifting out data in slots 2 - 7 when playing 2 channel audio. The codec is master and only works at 256 x fs, so after the frame sync slots 0 and 1 transfer as they should but after that data continues to be shifted out. It is my understanding that the remaining bits should be zero padded. On a similar note I see that the I2S bcm2835-i2s driver only supports 2 slots, but it seems it can also do 8. For example if I take an 8 channel audio source file(NOTE: I had to hack the file to look like 2 channels so hw_params didn't return an error) and play it I hear the first two channels fine and in the part that I am writing the dirver for I can easily route the other slots to additional DACs and get those to play as well. So I guess I am wondering about two things: 1. In the first case why does my 2 channel audio get shifted out on all 8 slots? It seems if configured for 2 it should only shift data in the first two and wait for the next fsync before starting to shift again. 2. Why does the driver obly support 2 channels when it seems the hardware is capable of more? I figure there is something about this controller that made this tricky or impossible, but I am still curious about it. Regards, Steven

[alsa-devel] azx_probe() called twice

25 Apr '18

Dear Linux folks, With the attached debug patch, `azx_probe()` seems to have been called twice on the ASRock E350M1. Is that expected? It also differs, that it’s only called once during some boots, and twice during others.

[alsa-devel] [PATCH 0/8] arm: renesas: Change platform dependency to ARCH_RENESAS
by Geert Uytterhoeven 25 Apr '18

25 Apr '18

Hi all, Commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS") started the conversion from ARCH_SHMOBILE to ARCH_RENESAS for Renesas ARM SoCs. This patch series completes the conversion, by: 1. Updating dependencies for drivers that weren't converted yet, 2. Removing the ARCH_SHMOBILE Kconfig symbols on ARM and ARM64. The first 6 patches can be applied independently by subsystem maintainers. The last two patches depend on the first 6 patches, and are thus marked RFC. Thanks for your comments!

[alsa-devel] [PATCH] sound: core: Change return type to vm_fault_t
by Souptick Joarder 25 Apr '18

25 Apr '18

Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type.
