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/
