- 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.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
