Subject: [PATCH 0/2][RFC] ACPI / PM: Disable MSR T-state after resumed
Date: Sat, 26 Aug 2017 00:43:18 +0800 [thread overview]
Message-ID: <cover.1503678995.git.yu.c.chen@intel.com> (raw)
There is a growing number of reports that the MSR throttling has
been enabled after resumed back from suspend to ram, which impacts
the system performance. This patchset tries to address this issue
by turning off the T-state after resumed back.
