Alternative kernel package based on Arch Linux 6.19.9 with 12 upstream
SDCA backport patches that enable audio on Intel Panther Lake systems
(Dell XPS 2026 and similar hardware with CS35L57 SoundWire amps).
The stock 6.19.9 kernel lacks the SDCA class/function topology driver
code needed for PTL audio. These patches backport the SDCA support from
mainline v7.0 to the stable 6.19.x series.
Tested on Dell XPS 16 (Panther Lake): all 4 CS35L57 amps probe with
calibration, SDCA jack detection works, sof-soundwire sound card
registers successfully.
CONFIG_RUST is disabled to avoid build failures with newer Rust
toolchain versions. Rust is not required for audio functionality.
