Subject: [PATCH 0/3] perf: Support event alias in form foo-bar-baz
Date: Mon, 17 Jan 2022 23:10:12 +0800 [thread overview]
Message-ID: <1642432215-234089-1-git-send-email-john.garry@huawei.com> (raw)
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.
