From e2348afe702e9431f428e230be7f4ef8a1778b19 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 17 Apr 2023 10:27:07 -0500 Subject: platform/x86/intel/pmc: core: Always capture counters on suspend 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.
