The Panther Lake XPS 13 (audio subsystem 1028:0e54) drives all of its
speakers through two CS35L56 amplifiers behind the CS42L43 codec. Their
DSP firmware aliases (cs35l56-b2-dsp1-misc-10280e54-spkid{1,2,3}) were
added to linux-firmware on 2026-08-18 and ship in Arch's
linux-firmware-cirrus 20260910-2, but the stable channel's Arch snapshot
is still on 20260810-2. Without them the amps run ROM firmware and the
machine is completely silent; upstream 7.2 already selects the sidecar
amplifier path for this SSID, so no kernel change is involved.
Ship the 20260910-2 payload to stable as a self-retiring shim:
- fast ring, no upstream watch (sync: false): the version is deliberately
20260810-3, above the snapshot's 20260810-2 and below Arch's real
20260910-2, so the genuine package supersedes it in the same
transaction that upgrades linux-firmware-other once the snapshot
advances. Bumping pkgver would defeat that.
- the signed Arch package is verified against the Arch packager key in
keys/pgp/ and reinstalled as-is, minus the cs42l45 SDCA tree that Arch
moved out of linux-firmware-other in 20260910: on the stable snapshot
those 190 files are still owned by -other 20260810-2 and would
conflict. The nine 10280e54 links and the 39 new SDCA files are kept.
Verified on a DX13260: cold boot loads 10280e54-spkid1 v4.5.9 on both
amps with "Calibration applied", and a 440 Hz tone measured through the
internal microphones peaks 238x over the noise floor on the stock UCM
bridge route. Delete this recipe once stable's snapshot carries
linux-firmware >= 20260910.

Give background agent seats independent keymaps and check foreground keyboard compatibility per operation. Package the downstream patch with separate source integrity and build provenance, retaining the upstream ABI verifier.

Move the package from the stable-only fast ring into the ordinary edge-to-RC-to-stable pipeline. Update the replay and promotion instructions while keeping the Driver 0.27.0 qualification boundary explicit.

basecamp/omarchy#11653 added etc/udev/rules.d/60-omarchy-io-scheduler.rules. package() already ships the whole etc/ tree, so the rule lands on new installs with the next build; list it in backup= so pacman keeps a user's local edit of the rule across upgrades, like the other package-owned /etc drop-ins.

The in-tree 7.2 CVS driver we ship as the intel-cvs DKMS module requests its
"wake" line with devm_gpiod_get(). On the Dell XPS 14 DA14260 that pin
(\_SB.GPI1 20) is the shared GpioIo the four CS35L57 amplifiers read their
speaker ID from, so with this package installed every cs35l56 probe fails with
"error -EBUSY: Failed to get spk-id-gpios" and the machine has no sound card.
Carry Junjie Cao's upstream fix, "media: i2c: cvs: Get the wake IRQ without
claiming the GPIO" (Cc: stable, Fixes: 8e2b43d2c10b), applied to the
downloaded intel-cvs-core.c in prepare(). makepkg symlinks plain downloads
into srcdir and patch refuses symlinks, so the file is copied first. Drop the
patch once the stable tag we fetch from contains the fix.
