Can perf record support coresight trace and pmu events concurrently?

[lee19830115]

I tried to perf record coresight trace and pmu events (like l1d_cache, l1i_cache) concurrently. Always received an mmap error -22. Not sure if I could log both coresight events and pmu events concurrently? I could perf record them individually but not both concurrently. Thanks.

and post it as this is general linux question, on kernel mail list  http://vger.kernel.org/vger-lists.html
