perf evsel: Say which PMU Hardware event doesn't support sampling/overflow-interrupts
Help identify to the user the event with the unsupported sampling error.
Also suggest a corrective action.
BEFORE:
$ sudo ./oldperf record -e armv8_pmuv3/mem_access/,ccn/cycles/,armv8_pmuv3/l2d_cache/ true
Error:
PMU Hardware doesn't support sampling/overflow-interrupts.
AFTER:
$ sudo ./newperf record -e armv8_pmuv3/mem_access/,ccn/cycles/,armv8_pmuv3/l2d_cache/ true
Error:
ccn/cycles/: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat'
