Trying Out & Benchmarking The New Experimental Intel Xe Linux Graphics Driver

Oh, look, the GuC being slower and buggier than execlists! News at 11

So has anyone seen any indication that with the current / planned Xe (or i915 for that matter) driver there has been / will be any improvement in
DGPU power management so that, unlike on MSWindows, the ARC770 (for an example) doesn't in LINUX ALWAYS consume at least ~40W regardless of how lightly loaded it is,
how few & low resolution monitors are attached, et. al.?

I really don't understand how when they have power / clock management working to potentially reduce idle power, and the settings to turn off fans for lightly loaded GPUs that NO such thing appears to be possible in LINUX with any distribution / driver version or BIOS / OS ASPM et. al. settings.

It is a known bug AFAIK.
I believe it is caused by a mixture of issues between the kernel, Mesa, DE/compositors and x11 making it worse.
