136 * Kernel wide state
137 * This is a hack. This state should be moved through simulated memory
138 * during a yield. Though not much is being used here, so it's probably
139 * probably not a big deal.
140 *
141 * Just to add to this comment... The ndr is derived from simulated
142 * memory when the cl-runtime allocates an HsaQueueEntry and populates it
143 * for a kernel launch. So in theory the runtime should be able to keep
144 * that state around. Then a WF can reference it upon restart to derive
145 * kernel wide state. The runtime can deallocate the state when the
146 * kernel completes.
