drm/core: get rid of -Iinclude/drm

2015-05-13T09:28:22Z

This results in a warning when building out of tree: "cc1: warning: include/drm: No such file or directory [enabled by default]" Most code already uses #include correctly, so fix the instances that don't. Reported-by: Ville Syrjälä Signed-off-by: Maarten Lankhorst Signed-off-by: Daniel Vetter

drm: flip-work: change drm_flip_work_init prototype

2014-11-14T23:29:14Z

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

2014-11-14T23:25:35Z

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

kfifo API type safety

2013-11-15T00:32:23Z

This patch enhances the type safety for the kfifo API. It is now safe to put const data into a non const FIFO and the API will now generate a compiler warning when reading from the fifo where the destination address is pointing to a const variable. As a side effect the kfifo_put() does now expect the value of an element instead a pointer to the element. This was suggested Russell King. It make the handling of the kfifo_put easier since there is no need to create a helper variable for getting the address of a pointer or to pass integers of different sizes. IMHO the API break is okay, since there are currently only six users of kfifo_put(). The code is also cleaner by kicking out the "if (0)" expressions.

drm: add flip-work helper

2013-08-19T00:32:26Z

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
