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.

Subject: [PATCH 12/17] ASoC: SDCA: Rearrange FDL file messages
|
|
|
|
It is helpful to have something in the log showing which firmware file
|
|
was loaded by the driver. Update the existing FDL disk file debug
|
|
statement to just note that a disk file rather than ACPI file was used,
|
|
and add a new info printk that prints out the details of the loaded file
|
|
regardless of where that file came from. Likewise, sometimes it is
|
|
useful to get a message if the file-sets list is missing, although this
|
|
isn't technically an error so make it a debug.
