This revival addresses UMD changes in GPUvis for this series. GPUvis uses the perf library in igt-gpu-tools. Changes to the library are here - https://patchwork.freedesktop.org/series/93355/ GPUvis changes will be posted as a PR once the above library and kernel changes are pushed. Summary of the feature: Current platforms provide MI_REPORT_PERF_COUNT to query a snapshot of perf counters from a batch. This mechanism does not have consistent support on all engines for newer platforms. To support perf query, all new platforms use a mechanism to trigger OA report snapshots into the OA buffer by writing to a HW register from a batch. To lookup this report in the OA buffer quickly, the OA buffer is mmapped into the user space. This series implements the new query mechanism.
