drm: Fix flip-task docs

2023-11-14T09:23:12+00:00

Say that drm_flip_work_commit() is safe to call in atomic context. Turn the name into a hyperlink. Suggested-by: Daniel Vetter Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20231101103618.23806-3-tzimmermann@suse.de

drm: Remove struct drm_flip_task from DRM interfaces

2023-11-14T09:23:11+00:00

Contain struct drm_flip_task and its helper functions drm_flip_work_allocate_task() and drm_flip_work_queue_task() within drm_flip_work.c There are no callers outside of the flip-work code.

drm/kms-helpers: Use recommened kerneldoc for struct member refs

2017-01-25T15:18:57+00:00

I just learned that &struct_name.member_name works and looks pretty even. It doesn't (yet) link to the member directly though, which would be really good for big structures or vfunc tables (where the per-member kerneldoc tends to be long). Also some minor drive-by polish where it makes sense, I read a lot of docs ... v2: Comments from Gustavo.

drm: flip-work: change drm_flip_work_init prototype

2014-11-14T23:29:14+00:00

Now that we're using lists instead of kfifo to store drm flip-work tasks we do not need the size parameter passed to drm_flip_work_init function anymore. Moreover this function cannot fail anymore, we can thus remove the return code. Modify drm_flip_work_init users to take account of these changes.

drm: rework flip-work helpers to avoid calling func when the FIFO is full

2014-11-14T23:25:35+00:00

Make use of lists instead of kfifo in order to dynamically allocate task entry when someone require some delayed work, and thus preventing drm_flip_work_queue from directly calling func instead of queuing this call. This allow drm_flip_work_queue to be safely called even within irq handlers. Add new helper functions to allocate a flip work task and queue it when needed. This prevents allocating data within irq context (which might impact the time spent in the irq handler). Signed-off-by: Boris BREZILLON Reviewed-by: Rob Clark Signed-off-by: Dave Airlie

drm: Fixup flip-work kerneldoc

2014-04-29T10:33:35+00:00

Describe the fifo parameter. It seems like kerneldoc doesn't properly handle fields defined using a macro, so it will end up complaining about this anyway and not generate the documentation for it either. At least the kerneldoc is now complete. Signed-off-by: Thierry Reding Signed-off-by: Daniel Vetter

drm: add flip-work helper

2013-08-19T00:32:26+00:00

A small helper to queue up work to do, from workqueue context, after a flip. Typically useful to defer unreffing buffers that may be read by the display controller until vblank. v1: original v2: wire up docbook + couple docbook fixes Signed-off-by: Rob Clark Acked-by: Daniel Vetter Signed-off-by: Dave Airlie
