[PATCH 0/7] Unlock deeper package-C states (PC-10) and D3Cold

[Rodrigo Vivi]

For integrated graphics, this series mean the unlock of
deeper package-C states. With this, on MTL I'm glad to
see PC-10 even with display enabled (with eDP PSR).

On my DG2 I'm gladly getting the big saves of D3Cold when
display is off/idle. And everything working niftly on
the desktop environment.

But in order to achieve that, we need to relax the runtime
PM protection around VMs and exec_queue, as explained on
each individual patch touching them.

Please let me know your thoughts, specially around those
relaxation cases.

Thanks,
Rodrigo.
