Subject: selftests/sched_ext: testing on BPF CI
Hi Tejun, Andrea.
I tested a couple of variants of bpf-next + sched_ext source tree,
just sharing the results.
I found a working state: BPF CI pipeline ran successfully twice
(that's 8 build + run of selftests/sched_ext/runner in total).
Working state requires most patches between sched_ext/master and
sched_ext/for-6.14-fixes [1], and also the patch
"tools/sched_ext: Receive updates from SCX repo" [2]
On plain bpf-next the dsp_local_on test fails [3].
Without the patch [2] there is a build error [4]: missing
SCX_ENUM_INIT definition.
We probably don't want to enable selftests/sched_ext on BPF CI with
that many "temporary" patches. I suggest to wait until all of this is
merged upstream.
