[alsa-devel] [PATCH] ASoC: nau8825: erase pop noise by soft mute
by John Hsu 28 Nov '16

28 Nov '16

The patch is a solution to fix the following issue. Chrome OS Issue 54078: Chell_headphone pop back from S3 When the system resume from S3 and playing music, there is a pop noise happened. It looks like system changes the sound immediately from maximum volume to the volume configured by user in playback beginning. The sound signal changes sharply, and there is a DC offset in the signal to make pop noise. Therefore, the driver introduces the soft mute to avoid the side effect of the unstable signal.

[alsa-devel] [RFC 00/17] clk: Add per-controller locks to fix deadlocks
by Krzysztof Kozlowski 12 Nov '16

12 Nov '16

Hi, RFC, please, do not apply, maybe except patch #1 which is harmless. Introduction ============ The patchset brings new entity: clock controller representing a hardware block. The clock controller comes with its own prepare lock which is used then in many places. The idea is to fix the deadlock mentioned in commit 10ff4c5239a1 ("i2c: exynos5: Fix possible ABBA deadlock by keeping I2C clock prepared") and commit 34e81ad5f0b6 ("i2c: s3c2410: fix ABBA deadlock by keeping clock prepared"). Disclaimer ========== Request for comments, so: 1. Only exynos_defconfig builds, 2. A lot of FIXME/TODO note still, 3. Checkpatch not run, lines not aligned, 4. Other (non-exynos) drivers not converted, 5. Probably not yet bisectable, 6. Locking became quite complex. The previous one lock was simple. Inefficient and dead-lock prone but simple. Because of clock hierarchy spanning through controllers, the new locking became quite complicated. I don't like it but... Details ======= In Exynos-based boards case the deadlock occurs between clock's prepare_lock and regmap-i2c's lock: CPU #0: CPU #1: lock(regmap) s2mps11-clk: clk_prepare_lock() i2c-exynos: clk_prepare_lock() - wait lock(regmap) - wait The clk_prepare_lock() on both CPUs come from different clock drivers and components: 1. I2C clock is part of SoC block and is required by i2c-s3c2410/i2c-exynos5 driver, 2. S2MPS11 clock is separate device, however driver uses I2C regmap. The deadlock was reported by lockdep (always) and was happening in 20% of boots of Odroid XU3 with multi_v7 defconfig. Workaround for deadlock was implemented by removing prepare/unprepare calls from I2C transfers. However these are just workarounds... which after applying this patch can be reverted. Additionally Marek Szyprowski's work on domains/clocks/pinctrl exposed the deadlock again in different configuration. Comments as usual are welcomed.

[alsa-devel] [PATCH 00/10] ASoC: Intel: Skylake: Add support for D0i3
by Vinod Koul 09 Nov '16

09 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.

[alsa-devel] [PATCH v3 0/8] ASoC: topology: Remaining kernel patches
by mengdong.lin＠linux.intel.com 04 Nov '16

04 Nov '16

From: Mengdong Lin <mengdong.lin(a)linux.intel.com> 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. The user space code is also ready. Mengdong Lin (8): ASoC: topology: ABI - Add flags to PCM ASoC: topology: ABI - Add private data to PCM ASoC: topology: ABI - Define DAI physical PCM data formats ASoC: topology: ABI - Add HW configurations to BE DAI links ASoC: topology: ABI - Add flags and private data to BE DAI links ASoC: topology: ABI - Add name and stream name to BE DAI links ASoC: Define API to find a dai link ASoC: topology: Add support to configure existing BE DAI links include/sound/soc-dai.h | 15 +++-- include/sound/soc.h | 3 + include/uapi/sound/asoc.h | 67 +++++++++++++++++++ sound/soc/soc-core.c | 42 ++++++++++++ sound/soc/soc-topology.c | 166 ++++++++++++++++++++++++++++++++++++++++++++-- 5 files changed, 282 insertions(+), 11 deletions(-) -- 2.5.0

[alsa-devel] [PATCH] ASoC: tlv320aic31xx: add explicit support for tlv320dac31xx
by Nikita Yushchenko 25 Oct '16

25 Oct '16

tlv320dac31xx is a subset of tlv320aic31xx: - it does not have MIC inputs and ADC, thus capture is not supported, - it has analog inputs AIN1/AIN2 that can be mixed into output. Although tlv320dac31xx does work with tlv320aic31xx driver, this setup does register non-existent widgets and non-existent capture stream. Thus userspace lists non-existent objects in user interfaces, an can access these, causing operations with device registers that are declared as "reserved" in tlv320dac31xx datasheet. This patch fixes this situation by separating controls/widgets/routes into common, aic31xx-specific, and dac31xx-specific parts. Only parts that match actual hardware (as declared in "compatible" device tree property) are registered.
