The NVIDIA Deep Learning Accelerator (NVDLA) is an open source IP which is integrated into NVIDIA Jetson AGX Xavier, so add driver support for this accelerator."
v1->v2: *Rename nvdla_drm.[ch] to nvdla_drv.[ch] and rename nvdla_ioctl.h to nvdla_drm.h, move it to uapi. comments link: https://lore.kernel.org/lkml/20bac605-97e6-e5cd-c4e4-83a8121645d8@amd.com/ *Remove the onexistent filename in Makefile comments link: https://lore.kernel.org/lkml/202204201512.pp20MXT5-lkp@intel.com/ *Sort file names alphabetically in Makefile. *Rearrange the error messages, and use drm_err/_dbg() instead of pr_err/_dbg(). *Replace "dla_" prefix with "nvdla_" *Check the iosys_map by iosys_map_is_null(), and check "ret" directly. *Using iosys_map_memcpy_to/_from() for iosys_map instead of memcpy() *Fix parameter error "dma_buf_vunmap(buf, ptr)", use "&map" instead of "ptr" *Use iosys_map instead of kvaddr and use "iosys_map_set_vaddr()" to initialize iosys_map *Using "vma->vm_pgoff -= drm_vma_node_start(&obj->vma_node)" to update vm_pgoff is cleaner *Remove the unused nvdla_drm_gem_mmap, register drm_gem_mmap to file_operations directly. *Use DEFINE_DRM_GEM_FOPS() to define nvdla_drm_fops. *Remove the unused nvdla_drm_gem_mmap_buf, register drm_gem_prime_mmap to drm_driver directly. comments link: https://lore.kernel.org/lkml/7fa19996-5830-af3d-ab24-08c76e1d5604@suse.de/ *Fix typo and some code style *Remove unused function nvdla_get_time_us() comments link: https://lore.kernel.org/lkml/0fa9ab41-c18e-a569-e6fe-a0e9d965905e@stargateun...
