Hi,
This is v2 of this series. You can read the overview and motivation in the cover letter of v1 [1].
I smoke-retested this version on a Meteor Lake system. It completed 50 cycles of suspend-to-disk and resume. I completed longer testing for v1.
Changes since v1: * Added locking to hfi_pm_notify() to serialize RMW operations on the MSR_IA32_HW_FEEDBACK_CONFIG register. (Rafael) * Relocated a comment regarding the reallocation of HFI memory to patch 3/4. (Rafael) * Clarified that patch 1/4 does not introduce functional changes. (Rafael) * Indicated the first stable version on which this patchset should be backported. * Renamed hfi_do_pm_[enable|disable]() as hfi_do_[enable|disable]() for future reuse. (Stan) * Registered the HFI suspend notifier towards the end of intel_hfi_init(). (Stan)
Thanks and BR, Ricardo
