[PATCH] drm/virtio: create context before RESOURCE_CREATE_2D in 3D mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If 3D is enabled, but userspace requests a dumb buffer, we will
call CTX_ATTACH_RESOURCE before actually creating the context.

Fixes: 72b48ae800da ("drm/virtio: enqueue virtio_gpu_create_context
                      after the first 3D ioctl")
