Workflow file for this run

name: Build ONIE (kvm_x86_64)
# Builds the generic amd64 ONIE image for the kvm_x86_64 target, intended
# to run as a VM under KVM/QEMU. The build follows the upstream-recommended
# containerized flow (see contrib/build-env and machine/kvm_x86_64/INSTALL),
# with secure boot disabled so no signing keys are required.

# Cache the crosstool-NG cross toolchain -- the long pole of a cold
# build. We must cache the entire stamp chain, not just the final
# toolchain, or ONIE's make will rebuild it: a missing download stamp
# (build/download) or project stamp (build/stamp-project) forces the
# chain to re-run from the top.
#
# build/stamp-project -- top-of-chain project stamp
# build/download -- toolchain source tarballs + download stamps
# build/crosstool-ng -- the crosstool-NG tool + its build stamps
# build/x-tools -- the installed cross toolchain + its stamps
#
# The key is tied to every input that can change the toolchain --
# including the Dockerfile, since it defines the compiler/host
# environment the toolchain is built in. No loose restore-keys: any
# input change forces a clean rebuild rather than restoring a
# mismatched toolchain.

# ONIE drives its build with stamp files compared by mtime. A fresh
# checkout gives every repo source file a current mtime, which is newer
# than the restored stamps -- so make would consider the toolchain
# stale and rebuild it (e.g. build/.../.config depends on the
# checked-out conf/crosstool config). A cache hit means the key
# matched, i.e. every toolchain input is unchanged and the restored
# toolchain is valid, so bump the restored artifacts ahead of the
# checkout to make "make xtools" a genuine no-op.
