[ Upstream commit f2b689ab2f8cc089cc7659c323f282e6a1fb6d64 ] An earlier commit placed some driverless devices in D3 during boot so that they don't block package cstate entry on Meteor Lake. Also place these devices in D3 after resume from suspend. Fixes: 336ba968d3e3 ("platform/x86/intel/pmc/mtl: Put GNA/IPU/VPU devices in D3") Signed-off-by: David E.

intel_pmc_core displays a warning when the module parameter `warn_on_s0ix_failures` is set and a suspend didn't get to a HW sleep state.

2023-04-20T17:06:12Z

Currently counters are only captured during suspend when the warn_on_s0ix_failures module parameter is set. In order to relay this counter information to the kernel reporting infrastructure adjust it so that the counters are always captured. warn_on_s0ix_failures will be utilized solely for messaging by the driver instead.

platform/x86/intel/pmc: Alder Lake PCH slp_s0_residency fix

2023-03-27T11:34:34Z

For platforms with Alder Lake PCH (Alder Lake S and Raptor Lake S) the slp_s0_residency attribute has been reporting the wrong value. Unlike other platforms, ADL PCH does not have a counter for the time that the SLP_S0 signal was asserted. Instead, firmware uses the aggregate of the Low Power Mode (LPM) substate counters as the S0ix value. Since the LPM counters run at a different frequency, this lead to misreporting of the S0ix time. Add a check for Alder Lake PCH and adjust the frequency accordingly when display slp_s0_residency.
