Re: [PATCH 11/14] drm/radeon/kms: enable the ttm dma pool if swiotlb is on V3

+#ifdef CONFIG_SWIOTLB

• if (swiotlb_nr_tbl()) {

• return ttm_dma_populate(ttm, rdev->dev);
  

• }

+#endif

..

+#ifdef CONFIG_SWIOTLB

• if (swiotlb_nr_tbl()) {

• ttm_dma_unpopulate(ttm, rdev->dev);
  

• return;
  

• }

+#endif

+#ifdef CONFIG_SWIOTLB

• if (rdev->need_dma32 && swiotlb_nr_tbl()) {

• sprintf(radeon_mem_types_names[i], "ttm_dma_page_pool");
  

• radeon_mem_types_list[i].name = radeon_mem_types_names[i];
  

• radeon_mem_types_list[i].show = &ttm_dma_page_alloc_debugfs;
  

• radeon_mem_types_list[i].driver_features = 0;
  

• radeon_mem_types_list[i++].data = NULL;
  

• }

+#endif

So I think the last one does not need the rdev->need_dma32 as you had removed it from the other sites.
