Applied, thanks for the quick fix. It is looking much neater now as well

Thanks Chris.
I feel unmasking of ARAT_EXPIRED is hard coding the behavior with GuC.
Ideally rps enabling should happen post GuC load in reset path like in load time flow.
That way instead of hard coding interrupts to be kept as ARAT_EXPIRED we will be able to derive from bits unmasked by GuC in PMINTRMSK.
So before GuC load, we should be resetting RPS interrupts (making PMINRMSK=~0u) and then derive interrupts to be kept unmasked by Host.
And then enable RPS. Current state is fine as we know GuC isn't using other PM interrupts. (might use some of those in SLPC)
