[alsa-devel] [PATCH 0/7] ALSA: hda: Enable HDAudio compress
by Cezary Rojewski 07 Jan '20

07 Jan '20

This set of patches provides new interfaces - page allocation - and runtime flow adjustments - PM support - for compress operations. For HDA part, work has been done to account for compress streams when servicing IRQs, setting up BDLs and assigning DMAs. End goal is to make room for one of DSP debug features: data probing. It takes advantage of compress streams when extracting data from running audio pipeline. Initial review and development of probes can be found under: https://github.com/thesofproject/linux/pull/1276 with this very set of patches being separated and reviewed on: https://github.com/thesofproject/linux/pull/1571 Cezary Rojewski (7): ALSA: hda: Allow for compress stream to hdac_ext_stream assignment ALSA: hda: Prepare for compress stream support ALSA: hda: Interrupt servicing and BDL setup for compress streams ALSA: core: Expand DMA buffer information ALSA: core: Implement compress page allocation and free routines ASoC: compress: Add pm_runtime support ASoC: SOF: Intel: Account for compress streams when servicing IRQs include/sound/compress_driver.h | 40 ++++++++++++++++++------ include/sound/hdaudio.h | 2 ++ include/sound/hdaudio_ext.h | 2 ++ sound/core/compress_offload.c | 42 ++++++++++++++++++++++++++ sound/hda/ext/hdac_ext_stream.c | 46 +++++++++++++++++++++++++--- sound/hda/hdac_controller.c | 4 +-- sound/hda/hdac_stream.c | 52 ++++++++++++++++++++------------ sound/soc/soc-compress.c | 29 +++++++++++++++++- sound/soc/sof/intel/hda-stream.c | 26 ++++++++++++++-- 9 files changed, 205 insertions(+), 38 deletions(-) -- 2.17.1

[alsa-devel] [PATCH] ASoC: rt5677: add SPI_MASTER dependency

When CONFIG_SPI is disabled, the newly added code for the DSP firmware loading fails to link: ERROR: "rt5677_spi_hotword_detected" [sound/soc/codecs/snd-soc-rt5677.ko] undefined! ERROR: "rt5677_spi_write" [sound/soc/codecs/snd-soc-rt5677.ko] undefined! Add a dependency to prevent this configuration.

[alsa-devel] [PATCH v5 00/11] ASoC: Add support to WCD9340/WCD9341 codec
by Srinivas Kandagatla 07 Jan '20

07 Jan '20

This patchset adds support to Qualcomm WCD9340/WCD9341 Codec which is a standalone Hi-Fi audio codec IC. This codec supports both I2S/I2C and SLIMbus audio interfaces. On slimbus interface it supports two data lanes; 16 Tx ports and 8 Rx ports. It has Five DACs and seven dedicated interpolators, Multibutton headset control (MBHC), Active noise cancellation, Sidetone paths, MAD (mic activity detection) and codec processing engine. It supports Class-H differential earpiece out and stereo single ended headphones out. This codec also has integrated SoundWire controller. Patchset for this is already sent for review at https://patchwork.kernel.org/cover/11185769/ This patchset has been tested on SDM845 based DragonBoard DB845c and Lenovo Yoga C630 laptop with WSA881x smart speaker amplifiers via soundwire and 4 DMICs. gpio controller patch does not have any link dependency, it can go by its own. Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team. Thanks, srini Changes since v4: - updated microvolt bindings as suggested by Rob. - slimbus optional property patch already applied.

[alsa-devel] [PATCH] ALSA: usb-audio: Add support for Presonus Studio 1810c
by mickflemm＠gmail.com 06 Jan '20

06 Jan '20

This patch adds support for Presonus Studio 1810c, a usb interface that's UAC2 compliant with a few quirks and a few extra hw-specific controls. I've tested all 3 altsettings and the added switch controls and they work as expected. More infos on the card: https://www.presonus.com/products/Studio-1810c Note that this work is based on packet inspection with usbmon.

[alsa-devel] topology file broadwell.conf
by Jaroslav Kysela 02 Jan '20

02 Jan '20

Hi all, I am working on some (major) cleanups for the topology library and I hit the issue with the topology file broadwell.conf in upstream. It cannot be compiled with the latest alsatplg / libatopology, because the SectionPCMConfig was removed in commit 368e4f2a897b5500573a2ee525f5504c135cfca2 in alsa-lib. Which driver is using this topology in the current linux kernel? Thanks, Jaroslav -- Jaroslav Kysela <perex(a)perex.cz> Linux Sound Maintainer; ALSA Project; Red Hat, Inc.
