The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'radeon_gart_table_ram_alloc()' GFP_KERNEL can be used because its callers already use this flag. Both 'r100_pci_gart_init()' (r100.c) and 'rs400_gart_init()' (rs400.c) call 'radeon_gart_init()'. This function uses 'vmalloc'. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- If needed, see post from Christoph Hellwig on the kernel-janitors ML: https://marc.info/?l=kernel-janitors&m=158745678307186&w=4 --- drivers/gpu/drm/radeon/radeon_gart.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/radeon/radeon_gart.c b/drivers/gpu/drm/radeon/radeon_gart.c index f178ba321715..b7ce254e5663 100644 --- a/drivers/gpu/drm/radeon/radeon_gart.c +++ b/drivers/gpu/drm/radeon/radeon_gart.c @@ -72,8 +72,8 @@ int radeon_gart_table_ram_alloc(struct radeon_device *rdev) { void *ptr; - ptr = pci_alloc_consistent(rdev->pdev, rdev->gart.table_size, - &rdev->gart.table_addr); + ptr = dma_alloc_coherent(&rdev->pdev->dev, rdev->gart.table_size, + &rdev->gart.table_addr, GFP_KERNEL); if (ptr == NULL) { return -ENOMEM; } @@ -110,9 +110,8 @@ void radeon_gart_table_ram_free(struct radeon_device *rdev) rdev->gart.table_size >> PAGE_SHIFT); } #endif - pci_free_consistent(rdev->pdev, rdev->gart.table_size, - (void *)rdev->gart.ptr, - rdev->gart.table_addr); + dma_free_coherent(&rdev->pdev->dev, rdev->gart.table_size, + (void *)rdev->gart.ptr, rdev->gart.table_addr); rdev->gart.ptr = NULL; rdev->gart.table_addr = 0; } -- 2.25.1
