Subject: [PATCH v4 0/2] perf pmus: Sort/merge/aggregate PMUs like mrvl_ddr_pmu
Date: Mon, 13 May 2024 17:13:57 -0700 [thread overview]
Message-ID: <20240514001359.2882951-1-irogers@google.com> (raw)
The mrvl_ddr_pmu is uncore and has a hexadecimal address
suffix. Current PMU sorting/merging code assumes uncore PMU names
start with uncore_ and have a decimal suffix. Add support for
hexadecimal suffixes and add tests.
v4. Workaround GCC build error by using unsigned types. Don't consider
short hex suffixes as suffixes (e.g. cpum_cf) and test this
behavior.
v3. Rebase and move tests from pmus.c to the existing pmu.c.
