Decrease the 3d resource refcount. If the count reaches zero, disable the fifo, switching to vga mode. Note that the master holds a refcount as well, and may request an explicit switch to vga mode when it releases its refcount to account for the situation of an X server vt switch to VGA with 3d resources active.

Put BO in VRAM if there is space, otherwise as a GMR. If there is no space in VRAM and GMR ids are all used up, start evicting GMRs to make room. If the DMA buffer can't be used as a GMR, this will return -ENOMEM.
If that failed, try VRAM again, this time evicting previous contents.

This function copies fence information to user-space. If copying fails, The user-space struct drm_vmw_fence_rep::error member is hopefully left untouched, and if it's preloaded with an -EFAULT by user-space, the error will hopefully be detected. Also if copying fails, user-space will be unable to signal the fence object so we wait for it immediately, and then unreference the user-space reference.

vmw_execbuf_fence_commands - create and submit a command stream fence
Creates a fence object and submits a command stream marker. If this fails for some reason, We sync the fifo and return NULL. It is then safe to fence buffers with a NULL pointer.
If is not NULL must also not be NULL. Creates a userspace handle if is not NULL, otherwise not.

vmw_execbuf_release_pinned_bo - Flush queries and unpin the pinned query bo.
: The device private structure. : Only flush and unpin if the current active query cid matches . : Optional context id to match.
This function should be used to unpin the pinned query bo, or as a query barrier when we need to make sure that all queries have finished before the next fifo command. (For example on hardware context destructions where the hardware may otherwise leak unfinished queries).
This function does not return any failure codes, but make attempts to do safe unpinning in case of errors.
The function will synchronize on the previous query barrier, and will thus not finish until that barrier has executed.

vmw_fifo_emit_dummy_query - emits a dummy query to the fifo.
: The device private structure. : The hardware context id used for the query.
This function is used to emit a dummy occlusion query with no primitives rendered between query begin and query end. It's used to provide a query barrier, in order to know that when this query is finished, all preceding queries are also finished.
A Query results structure should have been initialized at the start of the dev_priv->dummy_query_bo buffer object. And that buffer object must also be either reserved or pinned when this function is called.
Returns -ENOMEM on failure to reserve fifo space.

vmw_resource_unreserve - unreserve resources previously reserved for command submission.
: list of resources to unreserve.
Currently only surfaces are considered, and unreserving a surface means putting it back on the device's surface lru list, so that it can be evicted if necessary. This function traverses the resource list and checks whether resources are surfaces, and in that case puts them back on the device's surface LRU list.

vmw_surface_validate - make a surface available to the device, evicting other surfaces if needed.
: Pointer to a device private struct. : Pointer to a struct vmw_surface.
Try to validate a surface and if it fails due to limited device resources, repeatedly try to evict other surfaces until the request can be acommodated.
May return errors if out of resources.
