Pull Request Description
Fixed issue #200 by reading capabilities using the
capgetsystem call. Now, users other thanrootcan use PAPI to read uncore counters, provided they have one of the following capabilities:CAP_SYS_ADMINorCAP_PERFMON.Some rationale and future possibilities
I opted to use the
capgetsystem call directly, not to addlibcapas another dependency.I'd like to ask if there's any reason why system call numbers are manually defined. Would there
be any issue arising from the use of the
sys/syscall.hheader?Author Checklist
