IBS pmu can be invoked via fixed set of core pmu events with 'precise_ip' set to 1. Add a simple event open test for all these events. Without kernel fix: $ sudo ./perf test -vv 76 76: AMD IBS via core pmu : --- start --- test child forked, pid 6553 Using CPUID AuthenticAMD-25-1-1 type: 0x0, config: 0x0, fd: 3 - Pass type: 0x0, config: 0x1, fd: -1 - Pass type: 0x4, config: 0x76, fd: -1 - Fail type: 0x4, config: 0xc1, fd: -1 - Fail type: 0x4, config: 0x12, fd: -1 - Pass test child finished with -1 ---- end ---- AMD IBS via core pmu: FAILED!
