The exec bit was missing on prebuild.sh as committed in PR #15 (it landed mode 0644). Running './prebuild.sh' fails with 'Permission denied'; bash ./prebuild.sh works as a workaround but the shebang is intended to do its job. Caught while running the first linux-ampere-fourier build on boltzmann today. README.md examples show './prebuild.sh' so users will hit the same error. Single-bit fix via git update-index --chmod=+x. No content change.

# 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.
