# Perf package dropped for a range of Ubuntu releases, so we build it manually.
# See Ubuntu bug tracker:
# https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2117147

# Download perf version 6.17 to guarantee it has all code we need to cover
# AArch64 SPE and BRBE support. Can drop once perf is available in Ubuntu again
# and sufficiently recent.
