3  * Parts ported from amdgpu (fence wait code).
107  * Host-side wait on syncobjs
111  * host-side wait on all of the syncobj fences simultaneously.
112  * If &DRM_SYNCOBJ_WAIT_FLAGS_WAIT_ALL is set, the wait ioctl will wait on
119  * the host-side wait will first wait for the syncobj to receive a non-NULL
120  * fence and then wait on that fence.
124  * to do a host wait in one thread (or process) which waits on GPU work
130  * handles as well as an array of u64 points and does a host-side wait on all
133  * &DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT also adds the ability to wait for a given
136  * requirement is inherited from the wait-before-signal behavior required by
139  * Alternatively, &DRM_IOCTL_SYNCOBJ_EVENTFD can be used to wait without
141  * integrate the wait in an event loop.
