[ PATCH v2 0/3] Add Loongson I2S controller support
by YingKun Meng 13 Jun '23

13 Jun '23

Hi all, This patchset adds support for Loongson I2S controller, and introduce a ASoC machine driver for loongson platform. The Loongson I2S controller is available on Loongson 7a2000/2k2000 chips, works as a PCI device. It has two private DMA controllers used to playback and capture. Each DMA controller has one channel. The ASoC machine driver adds support for audio device which using loongson I2S controller to tranfser the audio data. The audio device uses "PRP0001" as its ACPI device ID, which provides a means to use the existing DT-compatible device identification in ACPI. Thanks. --- v2: * Use ACPI bindings to reference I2S and codec nodes. * Add 'required' restriction for sound-dai property in dt-bindings. * Fix build errors from lkp(a)intel.com. * Replace pci_xxx() APIs with pcim_xxx() APIs. * mirror changes in log printing. v1: * Add support for Loongson I2S controller.

[PATCH] regmap: maple: Don't sync read-only registers
by Takashi Iwai 13 Jun '23

13 Jun '23

regcache_maple_sync() tries to sync all cached values no matter whether it's writable or not. OTOH, regache_sync_val() does care the wrtability and returns -EIO for a read-only register. This results in an error message like: snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2f0009. -5 and the sync loop is aborted incompletely. This patch adds the writable register check in the loop for addressing the bug.

[PATCH 00/36] ALSA: Add MIDI 2.0 support
by Takashi Iwai 13 Jun '23

13 Jun '23

Hi, this is a (largish) patch set for adding the support of MIDI 2.0 functionality, mainly targeted for USB devices. MIDI 2.0 is a complete overhaul of the 40-years old MIDI 1.0. Unlike MIDI 1.0 byte stream, MIDI 2.0 uses packets in 32bit words for Universal MIDI Packet (UMP) protocol. It supports both MIDI 1.0 commands for compatibility and the extended MIDI 2.0 commands for higher resolutions and more functions. For supporting the UMP, the patch set extends the existing ALSA rawmidi and sequencer interfaces, and adds the USB MIDI 2.0 support to the standard USB-audio driver. The rawmidi for UMP has a different device name (/dev/snd/umpC*D*) and it reads/writes UMP packet data in 32bit CPU-native endianness. For the old MIDI 1.0 applications, the legacy rawmidi interface is provided, too. As default, USB-audio driver will take the alternate setting for MIDI 2.0 interface, and the compatibility with MIDI 1.0 is provided via the rawmidi common layer. However, user may let the driver falling back to the old MIDI 1.0 interface by a module option, too. A UMP-capable rawmidi device can create the corresponding ALSA sequencer client(s) to support the UMP Endpoint and UMP Group connections. As a nature of ALSA sequencer, arbitrary connections between clients/ports are allowed, and the ALSA sequencer core performs the automatic conversions for the connections between a new UMP sequencer client and a legacy MIDI 1.0 sequencer client. It allows the existing application to use MIDI 2.0 devices without changes. The MIDI-CI, which is another major extension in MIDI 2.0, isn't covered by this patch set. It would be implemented rather in user-space. Roughly speaking, the first half of this patch set is for extending the rawmidi and USB-audio, and the second half is for extending the ALSA sequencer interface. The patch set is based on 6.4-rc2 kernel, but all patches can be cleanly applicable on 6.2 and 6.3 kernels, too (while 6.1 and older kernels would need minor adjustment for uapi header changes). The updates for alsa-lib and alsa-utils will follow shortly later. The author thanks members of MIDI Association OS/API Working Group, especially Andrew Mee, for great helps for the initial design and debugging / testing the drivers.

Alsa without support to usb headphone
by GitHub issues - opened 12 Jun '23

12 Jun '23

alsa-project/alsa-lib issue #326 was opened from wellinton-capixaba: Hello. O recently built a media player (mplayer) with alsa support. However, telling mplayer to play multimedia files with alsa, specifying the usb headphone as the output device, didn't work. However, latter I built another mplayer, this time using the system provided Also. Then I redid the test, and it worked as I originally expected. The only difference I am aware between both also as is their version. The one I built it is the 1.0.17, while the system uses a 1.0.21. Can be this the cause of the problem. Or is something else?
