linux-toradex.git/drivers/gpu/drm/scheduler/Makefile, branch master Linux kernel for Apalis and Colibri modules drm/sched: Add scheduler unit testing infrastructure and some basic tests 2025-03-24T09:41:52+00:00 Tvrtko Ursulin tvrtko.ursulin@igalia.com 2025-03-24T09:26:29+00:00 5a99350794fec11faaed8a4b36a6931e696f672f Implement a mock scheduler backend and add some basic test to exercise the core scheduler code paths. Mock backend (kind of like a very simple mock GPU) can either process jobs by tests manually advancing the "timeline" job at a time, or alternatively jobs can be configured with a time duration in which case they get completed asynchronously from the unit test code. Core scheduler classes are subclassed to support this mock implementation. The tests added are just a few simple submission patterns.

Implement a mock scheduler backend and add some basic test to exercise the
core scheduler code paths.

Mock backend (kind of like a very simple mock GPU) can either process jobs
by tests manually advancing the "timeline" job at a time, or alternatively
jobs can be configured with a time duration in which case they get
completed asynchronously from the unit test code.

Core scheduler classes are subclassed to support this mock implementation.

The tests added are just a few simple submission patterns.

drm: move amd_gpu_scheduler into common location 2017-12-07T16:51:56+00:00 Lucas Stach l.stach@pengutronix.de 2017-12-06T16:49:39+00:00 1b1f42d8fde4fef1ed7873bf5aa91755f8c3de35 This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.
