drm/virtio: delete notify in virtio_gpu_object_create

2020-04-03T10:01:37Z

For 3D buffers, virtio_gpu_gem_object_open notifies. We can have the same behavior for dumb buffer. v2: virtio_gpu_gem_object_open always notifies v3: avoid boolean variable Signed-off-by: Gurchetan Singh Reviewed-by: Chia-I Wu Link: http://patchwork.freedesktop.org/patch/msgid/20200401223039.2860-3-gurchetansingh@chromium.org Signed-off-by: Gerd Hoffmann

drm/virtio: fix OOB in virtio_gpu_object_create

2020-03-19T11:00:24Z

After commit f651c8b05542 ("drm/virtio: factor out the sg_table from virtio_gpu_object"), virtio_gpu_create_object allocates too small space to fit everything in. It is because it allocates struct virtio_gpu_object, but should allocate a newly added struct virtio_gpu_object_shmem which has 2 more members. So fix that by using correct type in virtio_gpu_create_object.

drm/virtio: add case for shmem objects in virtio_gpu_cleanup_object(..)

drm/virtio: factor out the sg_table from virtio_gpu_object

2020-03-09T09:44:34Z

A resource will be a shmem based resource or a (planned) vram based resource, so it makes sense to factor out common fields (resource handle, dumb). v2: move mapped field to shmem object Signed-off-by: Gurchetan Singh Link: http://patchwork.freedesktop.org/patch/msgid/20200305013212.130640-1-gurchetansingh@chromium.org Signed-off-by: Gerd Hoffmann

drm/virtio: add virtio_gpu_is_shmem helper

2020-02-27T10:31:34Z

The plan is use have both shmem and virtual "vram" running side-by-side in virtio-gpu. It looks like we'll eventually use struct drm_gem_object as a base class, and we'll need to convert to shmem and vram objects on the fly. As a first step, add a virtio_gpu_is_shmem helper. Thanks to kraxel for suggesting this approach on Gitlab.
