Resetting the queue will reset 746 * lose all of that state. In order to minimize the collateral damage, the 747 * driver will save the ring contents which are not associated with the guilty 748 * context prior to resetting the queue. After resetting the queue the queue 749 * contents from the other contexts is re-emitted to the rings so that it can 750 * be processed by the engine. To handle this, we save the queue's write 751 * pointer (wptr) in the fences associated with each context. If we get a 752 * queue timeout, we can then use the wptrs from the fences to determine 753 * which data needs to be saved out of the queue's ring buffer. 754 */ 755 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
