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 [] [] -e, --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.
