The current code only prints PKGC-10 residency when the PKGC-10
is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we
also need to know other PKGC residency counters to better triage issues.
Ex:
1. When system is stuck in PC2, it can be caused short LTR from device.
2. When system is stuck in PC8, it can be caused by display engine.
To better triage issues, all PKGC residency are needed when issues happen.
Example log:
CPU did not enter Package C10!!! (Package C10 cnt=0x0)
Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724
Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0
Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0
Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0
Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0
Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0
Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0
With this log, we can know whether it's a stuck PC2 issue, and we can
check whether the short LTR from device causes the issue.

code in pdx86/for-next .
Commit 804951203a ("platform/x86:intel/pmc: Combine core_init() and
core_configure()") caused a network performance regression due to the GBE
LTR ignore that it added at probe. This was needed in order to allow the
SoC to enter the deepest Package C state. To fix the regression and at
least support PC10 during suspend, move the LTR ignore from probe to the
suspend callback, and enable it again on resume. This solution will allow
PC10 during suspend but restrict Package C entry at runtime to no deeper
than PC8/9 while a network cable it attach to the PCH LAN.

they don't block package cstate entry on Meteor Lake. Also place these

commit c5ad454a12 ("platform/x86: intel/pmc/core: Add Meteor Lake
support to pmc core driver") was supposed to add support for Meter
Lake P/M and mistakenly added support for Meteor Lake S instead. Meteor
Lake P/M support was added later and MTL-S support needs to be removed
since its currently assigned to the wrong register maps.

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.
Report this to the standard kernel reporting infrastructure so that
userspace software can query after the suspend cycle is done.

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.
