Subject: [PATCH v2 0/2] Fixes for s3 with parallel bootup
Date: Thu, 26 Oct 2023 12:03:28 -0500 [thread overview]
Message-ID: <20231026170330.4657-1-mario.limonciello@amd.com> (raw)
Parallel bootup on systems that use x2apic broke suspend to ram.
This series ensures x2apic is re-enabled at startup and fixes an exposed
pre-emption issue.
Mario Limonciello (2):
x86: Enable x2apic during resume from suspend if used previously
perf/x86/amd: Stop calling amd_pmu_cpu_reset() from amd_pmu_cpu_dead()
