SOF v2.3 Release

The SOF technical steering committee are pleased to announce the v2.3 release of SOF. This is the first release using Zephyr as the RTOS on selected platforms !

Signed binaries for selected Intel platforms should land in next few days.

Highlights

• Support for next generation AMD Rembrandt and Intel Raptorlake platforms.
• Zephyr RTOS on Intel Tigerlake platform as user "opt-in", defaults is TGL (xtos) on v2.2
• SIMD (Hifi3/4) Performance improvements on mixer, copier, PCM converter and volume components with up to 25-60% speed improvement depending on use case.
• SPARSE support added to codebase and used to partition memory pointers into cache and uncache types.

v2.2.2

v2.2.2 is to add support for Intel Raptor Lake (RPL) platform. v2.2.x is the stable release for Intel RPL and previous released products.

There is no change on FW or topology source code in this release.

RPL has the same community signed binaries as TGL, and same Intel-signed binaries as ADL. So new symbolic links will be created for RPL FW binaries. Please find more info in v2.2.2 binary release notes: https://github.com/thesofproject/sof-bin/releases/tag/v2.2.2

v2.2.1: topology: add sof-rpl-nocodec.tplg

This release includes topology updates for SoundWire, Intel APL/GLK platform with ES8336 codec, and Intel RPL platform.
There are no updates for the firmware and so the version of firmware binary are still v2.2

To use Intel RPL topologies, these 2 kernel patches are needed:

• 5f3db54c ASoC: Intel: common: add ACPI matching tables for Raptor Lake
• 63d375b9 ASoC: SOF: Intel: pci-tgl: use RPL specific firmware definitions

What's Changed from v2.2

• 3e2ccba topology: add sof-rpl-nocodec.tplg
• 1ae91d1 topology: add sof-rpl-rt711 and sof-rpl-rt711-4ch topologies
• 3de7d2b topology: Add platform definition file for Intel Raptor Lake
• 5cdc25b topology1: add SSP1 for all ES8336, SSP5 for APL/GLK
• ed43328 topology1: CMakeLists: add missing APL/GLK support for ES8336 with DMIC.
• b262943 topology1: sof-tgl-rt711-rt1308: use EXT_AMP_REF for rt1316
• 0a72a06 topology1: sof-tgl-rt711-rt1308: make BT_OFFLOAD a CMakeFiles parameter
• 4d93b4e topology1: CMakeLists: add topology for HP Omen 16
• 2830b81 topology1: sof-tgl-rt711-rt1308: make amplifier link configuration
• fb422ac topology1: generate new sof-hda-generic version for 2ch PDM1
• c8c8212 topology1: intel-generic-dmic: add macro to enable PDM1 for 2ch cases
• 5a015ca topology1: sof-tgl-rt711-rt1308: add missing switch

These topology updates are cherry picked to stable-v2.2 branch.

v2.1.1a

There is no firmware change from previous v2.1.1 release.

What's Changed
Add SoundWire topology for Intel Alder Lake (ADL) platforms without MIC

v2.2

The SOF Technical Stearting Committee are pleased to annouce the release of SOF v2.2.

v2.1.1

The SOF developers are pleased to announce the release of SOF v2.1.1
NOTE: The v2.1 release was delayed due to a late regression which meant a v2.1.1 release was required.

Release notes WIP

Features

• New Platforms - Support for Mediatek MT8186 added.
• New Processing - Support for Google AEC added.
• More Performance improvements in copy functions for most components with deprecation of the frag API. Some processing code paths improved by up to 18MCPS with the same audio quality.
• Stability improvements on multi-core support on Intel cAVS platforms which can now support running dynamic pipelines on any DSP core.
• Zephyr RTOS is now used instead of XTOS for community release for the APL and i.MX8 platforms.
• Initial support for Windows media player on certain TGL Windows-based devices via the IPC4 protocol.
