Hi, The initial goal of this series was to improve the drm and amdgpu trace events to be able to expose more of the inner workings of the scheduler and drivers to developers via tools. Then, the series evolved to become focused only on gpu_scheduler. The changes around vblank events will be part of a different series, as well as the amdgpu ones. Moreover Sima suggested to make some trace events stable uAPI, so tools can rely on them long term. The first patches extend and cleanup the gpu scheduler events. The last one adds a documentation entry in drm-uapi.rst. Changes since v6: * Addressed comments from Philipp, Tvrtko, Steven * The commit storing drm_client_id in sched_fence adds an extra field which looks like a duplicate of the owner field. Currently amdgpu uses the owner field with some magic values, so we have to have 2 separate fields for now, but ultimately one could be removed. Similarly storing the drm_client_id in the sched_entity is not really possible as there's nothing preventing a driver to use a sched_entity with multiple drm_file instances.
