Arch: version 147→148, drop enable_nacl (removed upstream), fix nv12-external-oes patch context for 148 (base/numerics/safe_conversions.h include removed upstream). Header comment updated: native build fiction → cross-compile reality. Debian: new build-deb.sh that assembles .deb from pre-built artifacts on CT 220 (data). Same binary artifacts as the Arch package, launcher at /usr/bin/chromium-fourier (no Conflicts with stock chromium on Debian). Both packages published to packages.reauktion.de: - Arch: marfrit/aarch64/chromium-fourier 1:148.0.7778.178-1 - Debian: trixie+bookworm/main/arm64 chromium-fourier 1:148.0.7778.178-1 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# Chromium with V4L2 HW video decode unlocked on Linux for Rockchip
|
|
# (RK3566 hantro / RK3588 VDPU381) on **mainline** kernel + Wayland +
|
|
# panfrost / panthor — no vendor MPP, no Mali blob, no panfork, no
|
|
# 5.10 BSP kernel. Fills the niche that 7Ji's chromium-mpp explicitly
|
|
# does not (it forces BSP + X11 + vendor stack); see STUDY.md and
|
|
# NEXT.md alongside this PKGBUILD for the full rationale and the
|
|
# validation log on PineTab2 (RK3566).
|
|
#
|
|
# Cross-compiled from x86_64 using chromium's bundled clang (upstream
|
|
# LLVM doesn't ship clang 23+ yet; chromium's internal fork is required).
|
|
# Runtime target is aarch64. The three patches are architecture-independent.
