drm: Constify drm_mode_config atomic helper private pointer

2017-02-12T11:05:23+00:00

The drm_mode_config helper private field points to a structure of function pointers that don't need to be modified at runtime. Make it const.

drm/virtio: Call drm_helper_mode_fill_fb_struct() before drm_framebuffer_init()

2016-12-15T12:55:28+00:00

We want framebuffers to be mostly useable already before drm_framebuffer_init() get called, and so we will start demanding that all the interesting format/size/etc. information be filled in before drm_framebuffer_init(). drm_helper_mode_fill_fb_struct() will do that for us, so let's make sure it gets called before drm_framebuffer_init().

virtio-gpu: fix vblank events

2016-11-03T00:14:19+00:00

virtio-gpu sends vblank events in virtio_gpu_crtc_atomic_flush, and because of that it must be called for disabled planes too. Ask drm_atomic_helper_commit_planes to do that. v2: update to use new drm_atomic_helper_commit_planes() API. Signed-off-by: Gerd Hoffmann Signed-off-by: Gustavo Padovan Signed-off-by: Dave Airlie

drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit

2016-08-29T09:29:37+00:00

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

drm/virtgpu: Delete unnecessary checks before drm_gem_object_unreference_unlocked()

2016-07-18T07:11:29+00:00

The drm_gem_object_unreference_unlocked() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software.

drm/virtio: Don't reinvent a flipping wheel

2016-06-14T14:32:47+00:00

Now that the core helpers support nonblocking atomic commits there's no need to invent that wheel separately (instead of fixing the bug in the atomic implementation of virtio, as it should have been done!). v2: Rebased on top of commit e7cf0963f816fa44190caaf51aeffaa614c340c6 Author: Gerd Hoffmann Date: Tue May 31 08:50:47 2016 +0200 virtio-gpu: add atomic_commit function Cc: Gerd Hoffmann Tested-by: Gerd Hoffmann Reviewed-by: Gerd Hoffmann Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1465510073-20951-1-git-send-email-daniel.vetter@ffwll.ch

drm: virtgpu: Rely on the default ->best_encoder() behavior

2016-06-10T15:25:06+00:00

The virtgpu output exposes a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder() implementation and let the core call drm_atomic_helper_best_encoder() for us.

drm/atomic-helper: Massage swap_state signature somewhat

2016-06-10T14:52:12+00:00

- dev is redundant, we have state->atomic - add stall parameter, which must be set when swapping needs to stall for preceeding commits to stop looking at ->state pointers.
