This series enables perf branch stack sampling support on arm64 platform via a new arch feature called Branch Record Buffer Extension (BRBE). All relevant register definitions could be accessed here. https://developer.arm.com/documentation/ddi0601/2021-12/AArch64-Registers This series applies on v6.1-rc1. Changes in V4: - Changed ../tools/sysreg declarations as suggested - Set PERF_SAMPLE_BRANCH_STACK in data.sample_flags - Dropped perfmon_capable() check in armpmu_event_init() - s/pr_warn_once/pr_info in armpmu_event_init() - Added brbe_format element into struct pmu_hw_events - Changed v1p1 as brbe_v1p1 in struct pmu_hw_events - Dropped pr_info() from arm64_pmu_brbe_probe(), solved LOCKDEP warning
Folks, Gentle ping, any updates on this series ? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
