    Subject[PATCH 12/54] perf tools: Enable config raw and numeric events
    Date
    This patch allows setting config terms for raw and numeric events.
    For example:

    # perf stat -e cycles/name=cyc/ ls
    ...
    1821108 cyc
    ...

    # perf stat -e r6530160/name=event/ ls
    ...
    1103195 event
    ...

    # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
    ...
    # perf report --stdio
    ...
    # Samples: 124 of event 'cycles'
    46.61% 0.00% swapper [kernel.vmlinux] [k] cpu_startup_entry
    41.26% 0.00% swapper [kernel.vmlinux] [k] start_secondary
    ...
    # Samples: 91 of event 'evtx'
    ...
    93.76% 0.00% swapper [kernel.vmlinux] [k] cpu_startup_entry
    |
    ---cpu_startup_entry
    |
    |--66.63%--call_cpuidle
    | cpuidle_enter
    | |
    ...
