Subject: [PATCH v8 0/3] Cavium ARM64 uncore PMU support
Date: Tue, 25 Jul 2017 17:04:19 +0200 [thread overview]
Message-ID: <20170725150422.4775-1-jglauber@cavium.com> (raw)
Add support for various PMU counters found on the Cavium ThunderX and
OcteonTx SoC.
The driver provides common "uncore" functions to avoid code duplication and
support adding more device PMUs (like L2 cache) in the future.
Changes to v7:
- Check return code of kasprintf
- Check return code of ioremap
- Add some more comments
- Only call perf_pmu_register after event_init() assignment and list_add
- Various cosmetics
Changes to v6:
- Make driver stand-alone again without hooking into EDAC
- depend on ARCH_THUNDER
Changes to v5:
- Only allow built-in CONFIG_CAVIUM_PMU
- Drop unneeded export of perf_event_update_userpage()
- Simplify callbacks in edac code, move CONFIG_CAVIUM_PMU check
to header file
- Fix some sparse static warnings
- Add documentation
- Fix OCX TLK event_valid check
- Add group validation in event_init
- Add a guard variable to prevent calling init twice
- Use kasprintf and fix pmu name allocation
- Remove unneeded check for embedded pmu
- Loop around local64_cmpxchg
- Simplify cvm_pmu_lmc_event_valid
- Fix list_add error case
