Function Documentation

void vmw_execbuf_copy_fence_user	(	struct vmw_private *	dev_priv,
		struct vmw_fpriv *	vmw_fp,
		int	ret,
		struct drm_vmw_fence_rep __user *	user_fence_rep,
		struct vmw_fence_obj *	fence,
		uint32_t	fence_handle
	)

vmw_execbuf_copy_fence_user - copy fence object information to user-space.

: Pointer to a vmw_private struct. : Pointer to the struct vmw_fpriv representing the calling file. : Return value from fence object creation. : User space address of a struct drm_vmw_fence_rep to which the information should be copied. : Pointer to the fenc object. : User-space fence handle.

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.

void vmw_execbuf_release_pinned_bo	(	struct vmw_private *	dev_priv,
		bool	only_on_cid_match,
		uint32_t	cid
	)

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.
