The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script bellow. It has been compile tested.
This also aligns code with what is in use in '/rsxx/dma.c' @@ @@ - 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.jail...@wanadoo.fr> --- If needed, see post from Christoph Hellwig on the kernel-janitors ML: https://marc.info/?l=kernel-janitors&m=158745678307186&w=4 For an example of code used in '/rsxx/dma.c', see: https://elixir.bootlin.com/linux/v5.7.8/source/drivers/block/rsxx/dma.c#L951 --- drivers/block/rsxx/core.c | 30 ++++++++++++++++-------------- 1 file changed, 16 insertions(+), 14 deletions(-) diff --git a/drivers/block/rsxx/core.c b/drivers/block/rsxx/core.c index 9230f453bb8b..e631749e14ca 100644 --- a/drivers/block/rsxx/core.c +++ b/drivers/block/rsxx/core.c @@ -562,13 +562,15 @@ static int rsxx_eeh_frozen(struct pci_dev *dev) for (i = 0; i < card->n_targets; i++) { if (card->ctrl[i].status.buf) - pci_free_consistent(card->dev, STATUS_BUFFER_SIZE8, - card->ctrl[i].status.buf, - card->ctrl[i].status.dma_addr); + dma_free_coherent(&card->dev->dev, + STATUS_BUFFER_SIZE8, + card->ctrl[i].status.buf, + card->ctrl[i].status.dma_addr); if (card->ctrl[i].cmd.buf) - pci_free_consistent(card->dev, COMMAND_BUFFER_SIZE8, - card->ctrl[i].cmd.buf, - card->ctrl[i].cmd.dma_addr); + dma_free_coherent(&card->dev->dev, + COMMAND_BUFFER_SIZE8, + card->ctrl[i].cmd.buf, + card->ctrl[i].cmd.dma_addr); } return 0; @@ -711,15 +713,15 @@ static pci_ers_result_t rsxx_slot_reset(struct pci_dev *dev) failed_hw_buffers_init: for (i = 0; i < card->n_targets; i++) { if (card->ctrl[i].status.buf) - pci_free_consistent(card->dev, - STATUS_BUFFER_SIZE8, - card->ctrl[i].status.buf, - card->ctrl[i].status.dma_addr); + dma_free_coherent(&card->dev->dev, + STATUS_BUFFER_SIZE8, + card->ctrl[i].status.buf, + card->ctrl[i].status.dma_addr); if (card->ctrl[i].cmd.buf) - pci_free_consistent(card->dev, - COMMAND_BUFFER_SIZE8, - card->ctrl[i].cmd.buf, - card->ctrl[i].cmd.dma_addr); + dma_free_coherent(&card->dev->dev, + COMMAND_BUFFER_SIZE8, + card->ctrl[i].cmd.buf, + card->ctrl[i].cmd.dma_addr); } failed_hw_setup: rsxx_eeh_failure(dev); -- 2.25.1
