Use the new __nullable CFI # stub tags instead. # # - On Sapphire Rapids multi-socket systems, a BPF scheduler, by # hammering on the same queue across sockets, could live-lock the # system to the point where the system couldn't make reasonable forward # progress. # # This could lead to soft-lockup triggered resets or stalling out # bypass mode switch and thus BPF scheduler ejection for tens of # minutes if not hours. After trying a number of mitigations, the # following set worked reliably: # # - Injecting artificial cpu_relax() loops in two places while # sched_ext is trying to turn on the bypass mode. # # - Triggering scheduler ejection when soft-lockup detection is # imminent (a quarter of threshold left). # # While not the prettiest, the impact both in terms of code complexity # and overhead is minimal. # # - A common complaint on the API is the overuse of the word "dispatch" # and the confusion around "consume". This is due to how the dispatch # queues became more generic over time. Rename the affected kfuncs for # clarity. Thanks to BPF's compatibility features, this change can be # made in a way that's both forward and backward compatible. The # compatibility code will be dropped in a few releases. # # - Other misc changes # # * tag 'sched_ext-for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: (21 commits) # sched_ext: Replace scx_next_task_picked() with switch_class() in comment #
