Rebased and integrated review feedback from v3: * Removed vm->vm_context field * Use uninterruptible waiting in initial PD validation to avoid ERESTARTSYS * Return number of successful map/unmap operations in failure cases * Facilitate partial retry after failed map/unmap * Added comments with parameter descriptions to new APIs * Defined AMDKFD_IOC_FREE_MEMORY_OF_GPU write-only This patch series also adds Userptr support in patches 15-20.
