From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxx>
When we had to quickly deal with a tree build issue via merging
792d16b5375d ("drm/v3d: Move perfmon init completely into own unit"), we
promised to follow up with a nicer solution.
As in the process of eliminating the hardcoded defines we have discovered a few
issues in handling of corner cases and userspace input validation, the fix has
turned into a larger series, but hopefully the end result is a justifiable
cleanup.
Tvrtko Ursulin (12):
drm/v3d: Prevent out of bounds access in performance query extensions
drm/v3d: Prefer get_user for scalar types
drm/v3d: Add some local variables in queries/extensions
drm/v3d: Align data types of internal and uapi counts
drm/v3d: Fix potential memory leak in the timestamp extension
drm/v3d: Fix potential memory leak in the performance extension
drm/v3d: Validate passed in drm syncobj handles in the timestamp
extension
drm/v3d: Validate passed in drm syncobj handles in the performance
extension
drm/v3d: Move part of copying of reset/copy performance extension to a
helper
drm/v3d: Size the kperfmon_ids array at runtime
drm/v3d: Do not use intermediate storage when copying performance
query results
drm/v3d: Move perfmon init completely into own unit
