Subject: [PATCH 0/6] perf/x86/intel/uncore: Bug fixes and cleanups
Date: Mon, 11 May 2026 16:05:21 -0700	[thread overview]
Message-ID: <20260511230527.26096-1-zide.chen@intel.com> (raw)

This series includes bug fixes and cleanups for the Intel uncore PMU
driver.

- Patch 1 fixes a theoretical bug in discovery unit lookup on multi-die
  systems.
- Patch 2 fixes a PCI device refcount leak in UPI topology discovery.
- Patch 3 works around a hardware issue on Raptor Cove CPUs.
- Patches 4-6 implement a global MSR init callback for GNR/GRR/SRF/CWF
  uncore.
