A couple more comments for things i just realised:
quoted hunk ↗ jump to hunk
+ /* + * Now that all the counters are disabled, we can safely turn the PMU on, + * without syncing the status of the counters + */ + __cci_pmu_enable(cci_pmu, CCI_CNTRS_NOSYNC);
As per my other comment, __cci_pmu_enable_nosync(cci_pmu) would be preferable. [...]
+ pmu_write_counter(cci_pmu, + (u32)local64_read(&event->hw.prev_count), i);
That cast can go. Mark.
