Hi Timur,

 

A quick = follow-up from the same MacPro6,1 with dual FirePro = D700s.

 

I have now tested the fixes after they reached stock = stable kernels:

 

- Linux = 6.18.57-1-lts:

=C2=A0 both GPUs = correctly transition from 300/150 MHz idle to 850/1370 MHz under Vulkan = compute load, then return to 300/150 MHz afterward.

 

- Linux = 7.2.10-arch1-1:

=C2=A0 same result; = both D700s reach 850/1370 MHz correctly under load.

 

For = comparison, Linux 7.2.9, before these stable backports, still kept both = GPUs at 300/150 MHz under the same type of compute = workload.

 

So I can confirm that the stable backports = of:

 

=C2=A0 drm/amd/pm/si: Check AMD_IS_MOBILITY flag for = PPSMC_SYSTEMFLAG_GPIO_DC

=C2=A0 = drm/amd/pm/si: Fix updating clock limits on AC/DC

 

resolve the = DPM issue on the dual FirePro D700 in the MacPro6,1.

 

Thanks for = the fixes.

 

Best,

Mikael
