Resetting the queue will reset 744 * lose all of that state. In order to minimize the collatoral damage, the 745 * driver will save the ring contents which are not associated with the guilty 746 * context prior to resetting the queue. After resetting the queue the queue 747 * contents from the other contexts is re-emitted to the rings so that it can 748 * be processed by the engine. To handle this, we save the queue's write 749 * pointer (wptr) in the fences associated with each context. If we get a 750 * queue timeout, we can then use the wptrs from the fences to determine 751 * which data needs to be saved out of the queue's ring buffer. 752 */ 753 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
