[PATCH 05/10] perf, tools: Special case uncore_ prefix
From: Andi Kleen
Date: Thu Feb 23 2017 - 19:10:59 EST
From: Andi Kleen <ak@xxxxxxxxxxxxxxx>
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
