amdkfd: Add device queue manager module The queue scheduler divides into two sections, one section is process bounded and the other section is device bounded. The device bounded section is handled by this module. The DQM module handles queue setup, update and tear-down from the device side. It also supports suspend/resume operation. v3: Changed device_init, added the use of the new gart allocation functions an Added documentation. v4: Fixed a race in DQM queue scheduler where dqm->lock must be held when accessing dqm->queue_count and dqm->processes_count. This fixes runlist IB allocation failures when DQM is under load. Fixed race in DQM queue destruction where queues being destroyed must be removed from qpd->queues_list prior to preemption, or concurrent queue creation activity may reschedule them while their MQD is destroyed. Fixed EOP queue size setting in CP_HPD_EOP_CONTROL, because the size is specified as (log2(size_dwords)-1). The previous calculation assumed the size was specified in bytes, which caused interference between EOP queues when multiple MEC pipelines were active. v5: Move amdkfd from drm/radeon/ to drm/amd/ Change format of mqd structure to match latest KV firmware Add support for AQL queues creation to enable working with open-source HSA runtime Remove unused unmap_queue function Various fixes (Style, typos) Signed-off-by: Ben Goz <ben.goz@amd.com> Signed-off-by: Jay Cornwall <jay.cornwall@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>
