drm/virtio: fix unblank

2020-09-02T06:12:45+00:00

When going through a disable/enable cycle without changing the framebuffer the optimization added by commit 3954ff10e06e ("drm/virtio: skip set_scanout if framebuffer didn't change") causes the screen stay blank. Add a bool to force an update to fix that. v2: use drm_atomic_crtc_needs_modeset() (Daniel).

drm/virtio: Remove open-coded commit-tail function

Exactly matches the one in the helpers. This avoids me having to roll out dma-fence critical section annotations to this copy.

drm/virtio: remove _unlocked suffix in drm_gem_object_put_unlocked

2020-05-19T21:31:36+00:00

Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner. Done via the following script: __from=drm_gem_object_put_unlocked __to=drm_gem_object_put for __file in $(git grep --name-only $__from); do sed -i "s/$__from/$__to/g" $__file; done Cc: David Airlie Cc: Gerd Hoffmann Cc: Daniel Vetter Signed-off-by: Emil Velikov Acked-by: Sam Ravnborg Acked-by: Gerd Hoffmann Acked-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20200515095118.2743122-36-emil.l.velikov@gmail.com

drm/virtgpu: Use simple encoder

drm/virtio: batch plane updates (pageflip)

2020-02-17T13:50:49+00:00

Move virtio_gpu_notify() to higher-level functions for virtio_gpu_cmd_resource_flush(), virtio_gpu_cmd_set_scanout() and virtio_gpu_cmd_transfer_to_host_{2d,3d}(). virtio_gpu_primary_plane_update() will notify only once for a series of commands (restores plane update command batching).

drm/virtio: add drm_driver.release callback.

2020-02-12T09:24:08+00:00

Split virtio_gpu_deinit(), move the drm shutdown and release to virtio_gpu_release(). Drop vqs_ready variable, instead use drm_dev_{enter,exit,unplug} to avoid touching hardware after device removal. Tidy up here and there. v4: add changelog. v3: use drm_dev_*().
