tools/power turbostat: v2024.04.10 (2024-04-10 09:07:57 -0400)
----------------------------------------------------------------
Turbostat version 2024.04.10
Use of the CPU MSR driver is now optional.
Perf is now preferred for many counters.
Non-root users can now execute turbostat, though with limited function.
Add counters for some new GFX hardware.
Minor fixes.

Tssk. Things like this should still come in during the merge window
and preferably be in linux-next.
I have pulled this, since it's obviously just tooling (and the
maintainer file pattern update), but stil...

ISTR that once upon a time at the kernel summit you expressed a
preference that things
like utilities (which sometimes depend on merge window changes) come
in after rc1 is declared
to basically stay out of the way.
Yes, this batch was delayed a week or so after that due to some revisions...
Happy to send this kind of thing during the merge window when
dependencies allow (yes, they would have this time)
since that is your current preference.
Also, yes, I can have my turbostat branch routinely included in linux-next.
thanks,
-Len

That may have been true at some point, but probably long ago - the
merge windows have been so reliable that it's just not an issue any
more.
So I'd rather see people hold to the normal release cycle, and aim to
have the rc releases for fixes or major problems.
We also used to allow entirely new drivers etc outside the release
cycle as a "this cannot regress" exception to the normal rules, but
that has also been largely abandoned as the release cycle is just
short enough that it makes no sense.
So the "new hardware support" rule has basically been watered down
over the years, and has become a "new hardware IDs are fine" kind of
rule, where just adding basically just a PCI ID or OF matching entry
or similar is still fine, but no more "whole new drivers".
