Currently event aliases in the form foo-bar-baz are not supported.
The HiSilicon D06 platform has uncore event aliases in that form, and using those aliases fail:
$ ./perf list sdir-home-migrate
List of pre-defined events (to be used in -e):
uncore hha: sdir-home-migrate [Unit: hisi_sccl,hha]
$ sudo ./perf stat -e sdir-home-migrate event syntax error: 'sdir-home-migrate' \___ parser error Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event>event selector. use 'perf list' to list available events
This series added support for such an event alias form.
I am no expert on l+y, so any and all review here would be appreciated, especially the last patch which is marked as RFC (for that same reason).
The series is based on acme perf/core @ 9bce13ea88f8.
