Drops the f8f3ad9 baseline ("18 commits ahead, BLACK-SCREENS ampere"
per fleet/ampere.yaml bisect note) in favor of the kernel-agent-
managed 10-patch set produced by ka-promote from fleet/ampere.yaml.
Baseline: mainline v7.0-rc3 (3daa4f5dc6cc), plus the 10 scope-tagged
patches under marfrit/kernel-agent/patches/{soc,module,board,driver}/:
- 1 soc/rk3588 pwm15 pinctrl
- 6 board/coolpi-cm5-genbook DTS patches
- 3 driver/media Sarma VP9-on-VDPU381 patches (PR #24 closure)
New _commit 48a8c78 reflects this tree state in ~/src/linux-rockchip
(branch vp9-build on ampere, exactly v7.0-rc3 + 10 manifest patches).
End-to-end verified before this iteration was cut (hand-build of the
same tip on 2026-05-18 booted ampere via arch_vp9_test extlinux
label):
- VP9 decode bit-exact HW==SW==libva (sha c8624d7c42db66525f53a02a515bc38d0a17ef39f692660cc7bebb1e2d2e1b48)
- AV1 decode bit-exact HW==SW via kdirect (sha 30d2091158d92f3c5e0a807217c3e7307f873267673d92632e7fb147383e7dd1, av1-vpu-dec is mainline 7.0)
prebuild.sh canonical sha256 cleared — gzip-version-dependent, the
script warns-not-fails on mismatch. First successful kafr2 build can
pin a canonical sha here if a reproducibility audit ever needs it.

# prebuild — stage the kernel source tarball this PKGBUILD expects.

# linux-ampere-fourier's source is a snapshot of marfrit/linux-rk3588-marfrit
|
|
# @ f8f3ad9 (260MB), too big to commit to marfrit-packages and currently
|
|
# unpushable to Gitea (boltzmann's working clone is shallow; gitea push
|
|
# refuses shallow updates). Hosting the tarball outside Gitea would need
|
|
# infrastructure setup that's not in scope for the first iteration.
|
|
#
|
|
# So: produce the tarball locally from the kernel working tree just
|
|
# before makepkg runs. Idempotent — if an existing tarball matches the
|
|
# expected sha256 we skip the archive step.
|
|
#
|
|
# Run from this directory: cd arch/linux-ampere-fourier && ./prebuild.sh
|
|
# Override the kernel-tree location: LINUX_RK3588_MARFRIT_TREE=/path ./prebuild.sh
|
|
#
|
|
# Default tree location matches the boltzmann/ampere convention from
|
|
# kernel-agent issue #6: $HOME/src/linux-rockchip.
