perf pmu: Special case uncore_ prefix
Special case uncore_ prefix in PMU match, to allow for shorter event uncore specifications. Before: perf stat -a -e uncore_cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1 After perf stat -a -e cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1 Committer tests: # perf list uncore List of pre-defined events (to be used in -e): uncore_cbox_0/clockticks/ [Kernel PMU event] uncore_cbox_1/clockticks/ [Kernel PMU event] uncore_imc/data_reads/ [Kernel PMU event] uncore_imc/data_writes/ [Kernel PMU event] # perf stat -a -e cbox_0/clockticks/ sleep 1 Performance counter stats for 'system wide': 281,474,976,653,084 cbox_0/clockticks/ 1.000870129 seconds time elapsed # Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Link: http://lkml.kernel.org/r/20170320201711.14142-7-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
