perf/x86/intel/uncore: Fix the bits of the CHA extended umask for SPR
The perf stat errors out with UNC_CHA_TOR_INSERTS.IA_HIT_CXL_ACC_LOCAL event. $perf stat -e uncore_cha_55/event=0x35,umask=0x10c0008101/ -a -- ls event syntax error: '..0x35,umask=0x10c0008101/' \___ Bad event or PMU The definition of the CHA umask is config:8-15,32-55, which is 32bit. However, the umask of the event is bigger than 32bit. This is an error in the original uncore spec. Add a new umask_ext5 for the new CHA umask range. Fixes: 949b11381f81 ("perf/x86/intel/uncore: Add Sapphire Rapids server CHA support") Closes: https://lore.kernel.org/linux-perf-users/alpine.LRH.2.20.2401300733310.11354@Diego/ Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Ian Rogers <irogers@google.com> Cc: stable@vger.kernel.org Link: https://lkml.kernel.org/r/20240708185524.1185505-1-kan.liang@linux.intel.com
