This is a revival of the patch series to support triggered perf query reports
from here - https://patchwork.freedesktop.org/series/83831/
The patches were not pushed earlier because corresponding UMD changes were
missing. 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.
