Subject: [PATCH 6/7] perf/x86/intel/uncore: Fix Intel SPR M2PCIE event constraints
Date: Thu, 26 Aug 2021 08:32:42 -0700	[thread overview]
Message-ID: <1629991963-102621-7-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1629991963-102621-1-git-send-email-kan.liang@linux.intel.com>

From: Kan Liang <kan.liang@linux.intel.com>

Similar to the ICX M2PCIE  events, some of the SPR M2PCIE events also
have constraints. Add the constraints for SPR M2PCIE.

Fixes: f85ef898f884 ("perf/x86/intel/uncore: Add Sapphire Rapids server M2PCIe support")
