Used only for no cp * scheduling mode. * * @update_mqd: Handles a update call for the MQD * * @destroy_mqd: Destroys the HQD slot and by that preempt the relevant queue. * Used only for no cp scheduling. * * @free_mqd: Releases the mqd buffer from local gpu memory. * * @is_occupied: Checks if the relevant HQD slot is occupied. * * @get_wave_state: Retrieves context save state and optionally copies the * control stack, if kept in the MQD, to the given userspace address. * * @mqd_mutex: Mqd manager mutex. * * @dev: The kfd device structure coupled with this module. * * MQD stands for Memory Queue Descriptor which represents the current queue * state in the memory and initiate the HQD (Hardware Queue Descriptor) state. * This structure is actually a base class for the different types of MQDs * structures for the variant ASICs that should be supported in the future. * This base class is also contains all the MQD specific operations. * Another important thing to mention is that each queue has a MQD that keeps * his state (or context) after each preemption or reassignment. * Basically there are a instances of the mqd manager class per MQD type per * ASIC. Currently the kfd driver supports only Kaveri so there are instances * per KFD_MQD_TYPE for each device. * */ extern int pipe_priority_map[]; struct mqd_manager { struct kfd_mem_obj* (*allocate_mqd)(struct kfd_node *kfd, struct queue_properties *q); void (*init_mqd)(struct mqd_manager *mm, void **mqd, struct kfd_mem_obj *mqd_mem_obj, uint64_t *gart_addr, struct queue_properties *q); int (*load_mqd)(struct mqd_manager *mm, void *mqd, uint32_t pipe_id, uint32_t queue_id, struct queue_properties *p, struct mm_struct *mms); void (*update_mqd)(struct mqd_manager *mm, void *mqd, struct queue_properties *q, struct mqd_update_info *minfo); int (*destroy_mqd)(struct mqd_manager *mm, void *mqd, enum kfd_preempt_type type, unsigned int timeout, uint32_t pipe_id, uint32_t queue_id); void (*free_mqd)(struct mqd_manager *mm, void *mqd, struct kfd_mem_obj *mqd_mem_obj); bool (*is_occupied)(struct mqd_manager *mm, void *mqd, uint64_t queue_address, uint32_t pipe_id, uint32_t queue_id); int (*get_wave_state)(struct mqd_manager *mm, void *mqd, struct queue_properties *q, void __user *ctl_stack, u32 *ctl_stack_used_size, u32 *save_area_used_size); void (*get_checkpoint_info)(struct mqd_manager *mm, void *mqd, uint32_t *ctl_stack_size); void (*checkpoint_mqd)(struct mqd_manager *mm, void *mqd, void *mqd_dst, void *ctl_stack_dst); void (*restore_mqd)(struct mqd_manager *mm, void **mqd, struct kfd_mem_obj *mqd_mem_obj, uint64_t *gart_addr, struct queue_properties *p, const void *mqd_src, const void *ctl_stack_src, const u32 ctl_stack_size); #if defined(CONFIG_DEBUG_FS) int (*debugfs_show_mqd)(struct seq_file *m, void *data); #endif bool (*check_preemption_failed)(struct mqd_manager *mm, void *mqd); uint64_t (*mqd_stride)(struct mqd_manager *mm, struct queue_properties *p); struct mutex mqd_mutex; struct kfd_node *dev; uint32_t mqd_size; }; struct mqd_user_context_save_area_header { /* Byte offset from start of user context * save area to the last saved top (lowest * address) of control stack data.
