2016-12-30drm/cma-helper: simplify setup for drivers with ->dirty callbacksDaniel Vetter1-4/+1
If we store the fb funcs pointer, we can remove a bit of boilerplate. Also remove the _fbdev_ in the example code, since the fb_funcs->dirty callback has nothing to do with fbdev. It's a KMS feature, only used by the fbdev deferred_io support to implement flushing/upload.

Add missing forward declaration for struct drm_plane and drm_plane_state, which causes the following warning in the VC4 driver (can be replicated by building using bcm2835_defconfig): In file included from drivers/gpu/drm/vc4/vc4_drv.c:18:0: include/drm/drm_fb_cma_helper.h:45:13: warning: ‘struct drm_plane_state’ declared inside parameter list will not be visible outside of this definition or declaration struct drm_plane_state *state); ^~~~~~~~~~~~~~~ include/drm/drm_fb_cma_helper.h:44:34: warning: ‘struct drm_plane’ declared inside parameter list will not be visible outside of this definition or declaration int drm_fb_cma_prepare_fb(struct drm_plane *plane, Signed-off-by: Marek Vasut <marex@denx.de> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20161115105529.3227-1-marex@denx.de
2016-11-14drm/fb_cma_helper: Add drm_fb_cma_prepare_fb() helperMarek Vasut1-0/+3
Add new drm_fb_cma_prepare_fb() helper function extracted from the imx-drm driver. This function checks if the plane has DMABUF attached to it, extracts the exclusive fence from it and attaches it to the plane state for the atomic helper to wait on it.

git://anongit.freedesktop.org/drm-intel into drm-next Ofc I promise just a few leftovers for drm-misc and somehow it's the biggest pull. But really mostly trivial stuff: - MAINTAINERS updates from Emil - rename async to nonblock in atomic_commit to avoid the confusion between nonblocking ioctl and async flip (= not vblank synced), from Maarten. Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation. Keeps the udl hack, and qxl is tested by Gerd. * tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel: (47 commits) drm: Fixup locking WARN_ON mistake around gem_object_free_unlocked drm/etnaviv: Use lockless gem BO free callback drm/imx: Use lockless gem BO free callback drm/radeon: Use lockless gem BO free callback drm/amdgpu: Use lockless gem BO free callback drm/gem: support BO freeing without dev->struct_mutex MAINTAINERS: Add myself for the new VC4 (RPi GPU) graphics driver.

2016-05-02drm/fb-cma-helper: Add fb_deferred_io supportNoralf Trønnes1-0/+14
This adds fbdev deferred io support if CONFIG_FB_DEFERRED_IO is enabled. The driver has to provide a (struct drm_framebuffer_funcs *)->dirty() callback to get notification of fbdev framebuffer changes. If the dirty() hook is set, then fb_deferred_io is set up automatically by the helper. Two functions have been added so that the driver can provide a dirty() function: - drm_fbdev_cma_init_with_funcs() This makes it possible for the driver to provided a custom (struct drm_fb_helper_funcs *)->fb_probe() function. - drm_fbdev_cma_create_with_funcs() This is used by the .fb_probe hook to set a driver provided (struct drm_framebuffer_funcs *)->dirty() function.

2015-11-24drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()Ville Syrjälä1-1/+1

To prevent it from happening again, pass the struct around as const, starting all the way from internal_framebuffer_create().
