- Add mechanism to count and report internal events. This significantly improves visibility on subtle corner conditions. - The default idle CPU selection logic is revamped and improved in multiple ways including being made topology aware. - sched_ext was disabling ttwu_queue for simplicity, which can be costly when hardware topology is more complex. Implement SCX_OPS_ALLOWED_QUEUED_WAKEUP so that BPF schedulers can selectively enable ttwu_queue. - tools/sched_ext updates to improve compatibility among others. - Other misc updates and fixes. - sched_ext/for-6.14-fixes were pulled a few times to receive prerequisite fixes and resolve conflicts. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZ999Sg4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGf/KAQCoMTVOBpQT9gCaCKDOmrVJTwi6boEoV5WnGZzw PDr0vwEAq36iz4no6Y5THcN/DCx+52IiS0zuhPy3rBZVo11TMgU= =iQ+A -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext updates from Tejun Heo: - Add mechanism to count and report internal events.
