drm/panthor: Extend VM locked region for remap case to be a superset

2026-04-13T15:16:07+00:00

In the event of an sm_step_remap() that leads to a partial unmap of a transparent huge page, the new locked region required by an extended unmap might not be a superset of the original one. Then, if it leaves a portion of the initially requested one out, the ensuing map will trigger a warning.

drm/panthor: extend timestamp query with flags

2026-03-24T16:04:40+00:00

Flags now control which data user space wants to query, there is more information sources, and there's ability to query duration of multiple timestamp reads. New sources: - CPU's monotonic, - CPU's monotonic raw, - GPU's cycle count These changes should make the implementation of VK_KHR_calibrated_timestamps more accurate and much simpler.
