  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.
