47 3.19 has the atomic modeset interfaces and helpers, so drivers can now be
73 helpers (and drivers then moved over to clipped coordinates). Probably the
74 helper should also be moved from drm_plane_helper.c to the atomic helpers, to
75 avoid confusion - the other helpers in that file are all deprecated legacy
76 helpers.
82 Improve plane atomic_check helpers
86 with the current helpers:
94 - Once that's done, helpers could stop calling ->atomic_check for disabled
104 Convert early atomic drivers to async commit helpers
107 For the first year the atomic modeset helpers didn't support asynchronous /
112 One issue with the helpers is that they require that drivers handle completion
116 the new atomic_async_check/commit functionality in the helpers in drivers that
241 helpers could further benefit from using struct iosys_map instead of
259 helpers might be subject to similar issues.
261 Benchmark and optimize fbdev's sys_() helpers and DRM's format-conversion
262 helpers. In cases that can be further optimized, maybe implement a different
264 That might possibly require architecture-specific helpers (e.g., storel()
274 A lot more drivers could be switched over to the drm_gem_framebuffer helpers.
377 For this task, we aim to introduce core helpers or reuse the existing ones
382 Introduce core helpers:
413 * Framebuffer copying and blitting helpers should operate on struct iosys_map.
439 pci_request_region() or similar functions. Use helpers for managed cleanup
504   helpers had their own (long removed), but on top of that the fbcon code itself

616 A good candidate for the first unit tests are the format-conversion helpers in

779 DRM driver. Simple KMS helpers and SHMEM should be able to handle any
784 driver with the help of the DRM fbconv helpers [4]_. These helpers provide
786 driver interface. Create a new DRM driver on top of the fbconv helpers,
