From: Kan Liang Date: Tue, 1 Jun 2021 13:09:03 +0000 (-0700) Subject: perf/x86/intel/uncore: Fix M2M event umask for Ice Lake server X-Git-Tag: v5.10.44~76 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=14831b79560b3408e0ea5d4ba37a465a04b70a11;p=thirdparty%2Fkernel%2Fstable.git perf/x86/intel/uncore: Fix M2M event umask for Ice Lake server commit 848ff3768684701a4ce73a2ec0e5d438d4e2b0da upstream. Perf tool errors out with the latest event list for the Ice Lake server. event syntax error: 'unc_m2m_imc_reads.to_pmm' \___ value too big for format, maximum is 255 The same as the Snow Ridge server, the M2M uncore unit in the Ice Lake server has the unit mask extension field as well.
