Running both tests cases 'perf trace enum augmentation tests'
and 'perf trace BTF general tests' together causes the first test case
to fail:
# for i in $(seq 5); do \
./perf test 'perf trace enum augmentation tests' \
'perf trace BTF general tests'; \
done
125: perf trace enum augmentation tests : Ok
126: perf trace BTF general tests : FAILED!
125: perf trace enum augmentation tests : Ok
126: perf trace BTF general tests : FAILED!
125: perf trace enum augmentation tests : Ok
126: perf trace BTF general tests : FAILED!
125: perf trace enum augmentation tests : Ok
126: perf trace BTF general tests : FAILED!
125: perf trace enum augmentation tests : Ok
126: perf trace BTF general tests : FAILED!
#
Test case perf trace enum augmentation tests' fails because the second
test case 'perf trace BTF general tests' runs concurrently as can
be observed using a ps -ef | grep perf output list on a different
window. Both do a perf trace command concurrently.
Make test case 'perf trace enum augmentation tests' exclusive.
# for i in $(seq 5); do \
./perf test 'perf trace enum augmentation tests' \
'perf trace BTF general tests'; \
done
125: perf trace BTF general tests : Ok
155: perf trace enum augmentation tests : Ok
125: perf trace BTF general tests : Ok
155: perf trace enum augmentation tests : Ok
125: perf trace BTF general tests : Ok
155: perf trace enum augmentation tests : Ok
125: perf trace BTF general tests : Ok
155: perf trace enum augmentation tests : Ok
125: perf trace BTF general tests : Ok
155: perf trace enum augmentation tests : Ok
