# Yocto (kas) build of rpilinux-image for raspberrypi4-64.
|
|
#
|
|
# Runner requirements (see chat/notes):
|
|
# - matches the instance runner's "ubuntu-latest" label (bare label = job
|
|
# runs on the runner's machine, i.e. a host job). Yocto needs ~250GB
|
|
# persistent disk, so the runner must actually be a machine (or a
|
|
# container with a big persistent volume), not a throwaway sandbox.
|
|
# - ~250GB free in $HOME, plus the poky host dependencies + node
|
|
# - runner.timeout >= 8h for the first build (runner default is 3h)
|
|
#
|
|
# Upgrade path: register a dedicated runner with label "yocto:host" and
|
|
# change runs-on below to "yocto".
