cachyos-kernel-builder

Builds the CachyOS kernel (linux-cachyos variant) with T2 Mac support, packaged as linux-cachyos-t2 + linux-cachyos-t2-headers. Built daily by GitHub Actions and published as a pacman repo on the rolling latest release.

What it changes vs stock linux-cachyos

• Applies T2 patches from klizas/t2-kernel-patches: amdgpu mclk override, brcmfmac suspend fix, Touch Bar suspend/resume.
• Ships out-of-tree apple-bce from klizas/apple-bce-drv (aur branch) as extramodules/apple-bce.ko. Disables every in-tree BCE driver CachyOS enables: CONFIG_APPLE_BCE (<= 7.1, drivers/staging/apple-bce) and CONFIG_T2BCE_DMA/CORE/VHCI/AUDIO (>= 7.2, drivers/staging/t2bce, claims the same PCI device 106b:1801). prepare() fails the build if any of them survives config reconciliation.
• Target: x86_64_v3 (matches cachyos-v3).
