I can confirm that commit 8032a1ae in LTP test suite has corrected this
issue.
It will now return TCONF instead of TBORK:
perf_event_open02 1 TCONF : perf_event_open02.c:274:
PERF_COUNT_HW_INSTRUCTIONS not supported: errno=ENOENT(2): No such file or
directory
perf_event_open02 2 TCONF : perf_event_open02.c:274: Remaining cases not
appropriate for configuration: errno=ENOENT(2): No such file or directory
