2017-01-25drm/kms-helpers: Use recommened kerneldoc for struct member refsDaniel Vetter1-1/+1
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.

2014-11-15drm: flip-work: change drm_flip_work_init prototypeBoris BREZILLON1-1/+1
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.

2014-11-15drm: rework flip-work helpers to avoid calling func when the FIFO is fullBoris BREZILLON1-8/+23
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).

2014-04-29drm: Fixup flip-work kerneldocThierry Reding1-0/+1
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 <treding@nvidia.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-08-19drm: add flip-work helperRob Clark1-0/+76
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 <robdclark@gmail.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
