Sound Open Firmware 2.9 Released With Major Performance Optimizations

Sound Open Firmware 2.9 has been released for this open-source project providing audio DSP firmware infrastructure and an adjoining SDK. This effort that started out by Intel for opening up more of their audio hardware firmware has expanded into a multi-vendor project with the likes of AMD and Mediatek also participating around this sound firmware infrastructure, audio driuvers, etc.

With Sound Open Firmware 2.9 there are "major" performance optimizations to the audio modules of Aria, Mixin/Mixout, and DRC. The release notes didn't spell out anything more about these major performance optimizations.

Sound Open Firmware 2.9 also enhances its loadable module support, more components have been migrated to the SOF Module API, and there are many bug fixes.

The Sound Open Firmware 2.9 release also brings new topologies for Intel and NXP hardware. On the Intel side there's been a lot of work recently with SOF for ironing out the Lunar Lake (LNL) platform support.
