2019-12-16drm/virtio: batch display update commands.Gerd Hoffmann1-2/+21
When the driver submits multiple commands in a row it makes sense to notify the host only after submitting the last one, so the host can process them all at once, with a single vmexit. Add functions to enable/disable notifications to allow that. Use the new functions for primary plane updates.

2019-09-04drm/virtio: switch from ttm to gem shmem helpersGerd Hoffmann1-6/+18
virtio-gpu basically needs a sg_table for the bo, to tell the host where the backing pages for the object are. So the gem shmem helpers are a perfect fit. Some drm_gem_object_funcs need thin wrappers to update the host state, but otherwise the helpers handle everything just fine. Once the fencing was sorted the switch was surprisingly easy and for the most part just removing the ttm code. v4: fix drm_gem_object_funcs name.

2019-09-04drm/virtio: rework virtio_gpu_execbuffer_ioctl fencingGerd Hoffmann1-5/+16
Rework fencing workflow, starting with virtio_gpu_execbuffer_ioctl. Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work on the reservation objects directly) instead. Also store the object array in struct virtio_gpu_vbuffer, so we explicitly keep a reference of all buffers used instead of depending on ttm_bo_put() checking whenever the object is actually idle before releasing it. New workflow: (1) All gem objects needed by a command are added to a virtio_gpu_object_array. (2) All reservation objects will be locked (virtio_gpu_array_lock_resv). (3) virtio_gpu_fence_emit() completes fence initialization. (4) fence gets added to the objects, reservation objects are unlocked (virtio_gpu_array_add_fence, virtio_gpu_array_unlock_resv). (5) virtio command is submitted to the host. (6) The completion callback (virtio_gpu_dequeue_ctrl_func) will drop object references and free virtio_gpu_object_array. v6: rewrite most of the patch.

Compounding this issue, virtio_gpu_cmd_capset_cb would stop iterating after find the first matching entry.

2019-03-28drm/virtio: rework resource creation workflow.Gerd Hoffmann1-6/+8
This patch moves the virtio_gpu_cmd_create_resource() call (which notifies the host about the new resource created) into the virtio_gpu_object_create() function. That way we can call virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host already knows about the object when ttm initializes the object and calls our driver callbacks. Specifically the object is already created when the virtio_gpu_ttm_tt_bind() callback invokes virtio_gpu_object_attach(), so the extra virtio_gpu_object_attach() calls done after virtio_gpu_object_create() are not needed any more. The fence support for the create ioctl becomes a bit more tricky though. The code moved into virtio_gpu_object_create() too. We first submit the (fenced) virtio_gpu_cmd_create_resource() command, then initialize the ttm object, and finally attach just created object to the fence for the command in case it didn't finish yet.

2018-08-30drm/virtio: fix bounds check in virtio_gpu_cmd_get_capset()Dan Carpenter1-2/+3
This doesn't affect runtime because in the current code "idx" is always valid. First, we read from "vgdev->capsets[idx].max_size" before checking whether "idx" is within bounds. And secondly the bounds check is off by one so we could end up reading one element beyond the end of the vgdev->capsets[] array.

Wait until we have enough space in the virt queue to actually queue up our request. Avoids the guest spinning in case we have a non-zero amount of free entries but not enough for the request.
