Aurora Silicon's fork of the Asahi kernel (DisplayPort alt-mode and USB4 for external displays, VRR, ISP and AOP drivers) as an aarch64-only split package, linux-aurora and linux-aurora-headers, pinned to an immutable commit that was cold-boot qualified on a MacBook Pro 14" M1 Pro and 16" M2 Max. It provides and conflicts with linux-asahi so Macs move over in one explicit transaction, and pkgrel 9 orders it after the last build the maralcbr fork published, so already-installed Macs upgrade on -Syu. Metadata: skip_build like the x86 kernels (built only by its own PR), release_ring fast with channels edge and rc, so one merge publishes the same artifact to edge/aarch64 and rc/aarch64 and stable keeps asahi-alarm's linux-asahi. No x86 job is emitted and no shared tooling changes.

# AArch64 Apple Silicon (Aurora Silicon)

# Based on the asahi-alarm linux-asahi package by Jos Dehaes and Matthias Kurz.
|

#
|
|
# Aurora Silicon maintain a fork of the Asahi kernel carrying DisplayPort
|
|
# alt-mode and USB4 support for external monitors, variable refresh rate, and
|
|
# the ISP and AOP drivers. Those changes touch device trees, the type-C stack
|
|
# and DRM, so they cannot ship as a module: this is a whole alternative kernel
|
|
# for Macs on the Omarchy edge and rc channels. The stable channel keeps
|
|
# asahi-alarm's linux-asahi.
