From: Ben Goz <ben....@amd.com> This patch adds four new functions to the kfd2kgd interface:
1. init_sdma_engines() - Initializes the SDMA engines through GPU registers. 2. hqd_sdma_load() - Loads SDMA mqd to a H/W SDMA hqd slot. Used only in no HWS mode. 3. hqd_sdma_is_occupied() - Checks if an SDMA hqd slot is occupied. Used only in no HWS mode. 4. hqd_sdma_destroy() - Destructs and preempts the SDMA queue assigned to that SDMA hqd slot. Used only in no HWS mode. These functions are needed to support SDMA queues scheduling.
