Hi Dave and Sima. Here's the drm-xe-fixes for 6.15-rc7.
We had quite a few more changes than usual due to 2 fixes that were being worked on for a few weeks: 1) engine utilization and 2) mixing cpu and gpu atomics. Those 2 required some refactors to get them right. Other than that, fixes are very simple. Summary: drm-xe-fixes-2025-05-15-1: Core Changes: - Add timeslicing and allocation restriction for SVM Driver Changes: - Fix shrinker debugfs name - Add HW workaround to Xe2 - Fix SVM when mixing GPU and CPU atomics - Fix per client engine utilization due to active contexts not saving timestamp with lite restore enabled.
