I am finding that this test hangs on my arm64 machine:
john@debian:~/kernel-dev2/tools/perf$ sudo ./perf test -vvv 73 73: Sigtrap: --- start --- test child forked, pid 45193
And fails on my x86 broadwell machine:
john@localhost:~/kernel-dev2/tools/perf> sudo ./perf test -v 73 73: Sigtrap : --- start --- test child forked, pid 22255 FAILED sys_perf_event_open(): Argument list too long test child finished with -1 ---- end ---- Sigtrap: FAILED! john@localhost:~/kernel-dev2/tools/perf>
Are there more architectures+platforms for which we need to skip this test?
Thanks, John
