2018-07-11drm/client: Fix: drm_client_new: Don't require DRM to be registeredNoralf Trønnes1-10/+1
Commit 894a677f4b3e ("drm/cma-helper: Use the generic fbdev emulation") broke almost all drivers that use the CMA helper. The reason is that drm_client_new() requires that the DRM device has been registered, but the drivers register fbdev before registering DRM. Remove the requirement that DRM should be registered when creating a new client.

Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels.

This switches the CMA helper drivers that use its fbdev emulation over to the generic fbdev emulation. It's the first phase of using generic fbdev. A later phase will use DRM client callbacks for the lastclose/hotplug/remove callbacks. There are currently 2 fbdev init/fini functions: - drm_fb_cma_fbdev_init/drm_fb_cma_fbdev_fini - drm_fbdev_cma_init/drm_fbdev_cma_fini This is because the work on generic fbdev came up during a fbdev refactoring and thus wasn't completed. No point in completing that refactoring when drivers will soon move to drm_fb_helper_generic_probe(). tinydrm uses drm_fb_cma_fbdev_init_with_funcs().

2018-07-10drm: Begin an API for in-kernel clientsNoralf Trønnes5-1/+402
This the beginning of an API for in-kernel clients. First out is a way to get a framebuffer backed by a dumb buffer. Only GEM drivers are supported. The original idea of using an exported dma-buf was dropped because it also creates an anonomous file descriptor which doesn't work when the buffer is created from a kernel thread. The easy way out is to use drm_driver.gem_prime_vmap to get the virtual address, which requires a GEM object. This excludes the vmwgfx driver which is the only non-GEM driver apart from the legacy ones. A solution for vmwgfx will have to be worked out later if it wants to support the client API which it probably will when we have a bootsplash client.

2018-07-07drm/crtc: Add a generic infrastructure to fake VBLANK eventsBoris Brezillon1-0/+39
In some cases CRTCs are active but are not able to generating events, at least not at every frame at it's expected to. This is typically the case when the CRTC is feeding a writeback connector that has no job queued. In this situation the CRTC is usually stopped until a new job is queued, and this can lead to timeouts when part of the pipeline is updated but no new jobs are queued to the active writeback connector. In order to solve that, we add a ->no_vblank flag to drm_crtc_state and ask the CRTC drivers to set it to true when they know they're not able to generate VBLANK events. The core drm_atomic_helper_fake_vblank() helper can then be used to fake VBLANKs at commit time.

2018-07-07drm/vc4: Use wait_for_flip_done() instead of wait_for_vblanks()Boris Brezillon1-10/+1
drm_atomic_helper_wait_for_vblanks() assumes the CRTC will continuously generate VBLANK events and the vblank counter will keep increasing. While this work for a regular pipeline, it doesn't when you have the CRTC is feeding the transposer block, because this block works in oneshot mode, and, by the time we reach drm_atomic_helper_wait_for_vblanks() the only VBLANK event might have already been sent and the VBLANK counter will stay unchanged, thus triggering a timeout. Luckily, we can replace the drm_atomic_helper_wait_for_vblanks() call by drm_atomic_helper_wait_for_flip_done() because the only thing we want to check when calling drm_atomic_helper_wait_for_vblanks() from vc4_atomic_complete_commit() is that new FBs are in use and the old ones can be safely released.

2018-07-07drm/connector: Make ->atomic_commit() optionalBoris Brezillon1-0/+2
Not all writeback connector implementations might want to commit things from the connector driver. Some, like the malidp driver, commit things from their main commit_tail() function, and would rather not have to implement a dummy hook for drm_connector_helper_funcs.atomic_commit(). Make this function optional and reflect this fact in the doc.
