drm/virtio: send vblank event after crtc updates

2016-04-26T23:32:04+00:00

virtio_gpu was failing to send vblank events when using the atomic IOCTL
with the DRM_MODE_PAGE_FLIP_EVENT flag set. This patch fixes each and
enables atomic pageflips updates.

drm: Drop drm_helper_probe_single_connector_modes_nomerge()

2015-12-11T08:32:53+00:00

Now that the mode type bit merge logic is fixed to only merge
between new probed modes, hopefully we can eliminat the special
case for qxl and virtio. That is make the merge the mode type
bits from all matching new probed modes, just like every other
driver.

qxl and virtio got excluded from the merging in
commit 3fbd6439e463 ("drm: copy mode type in drm_mode_connector_list_update()")
commit abce1ec9b08a ("Revert "drm: copy mode type in drm_mode_connector_list_update()"")
commit b87577b7c768 ("drm: try harder to avoid regression when merging mode bits")

drm: Pass 'name' to drm_encoder_init()

2015-12-11T08:13:20+00:00

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

drm: Pass 'name' to drm_crtc_init_with_planes()

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

I didn't convert drm_crtc_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

virtio-gpu: use no-merge for fill-modes

2015-12-01T00:33:35+00:00

Avoid the sticky preferred mode bit by using the no-merge version of the
function (this allows gnome-shell to resize to lower resolutions than
the default resolution)

drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()

2015-11-24T10:47:38+00:00

Drivers shouldn't clobber the passed in addfb ioctl parameters.
i915 was doing just that. To prevent it from happening again,
pass the struct around as const, starting all the way from
internal_framebuffer_create().
