Subject[PATCH v1 0/3] perf: Support a new coresum event qualifier
Date
The coresum event qualifier which sums up the event counts for both
hardware threads in a core. For example,

perf stat -e cpu/event=0,umask=0x3,coresum=1/,cpu/event=0,umask=0x3/

In this example, we count the event 'ref-cycles' per-core and per-CPU in
one perf stat command-line.

We can already support per-core counting with --per-core, but it's
often useful to do this together with other metrics that are collected
per CPU (per hardware thread). So this patch series supports this
per-core counting on a event level.

Jin Yao (3):
perf: Add a coresum event qualifier
perf stat: Support coresum event qualifier
perf test: Add a simple test for term coresum
