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 'mantis_alloc_buffers()' (mantis_dma.c) GFP_KERNEL can be used because it is called from 'mantis_dma_init()' which is only called from probe functions and no lock is taken in the between. @@ @@ - 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/media/pci/mantis/mantis_dma.c | 20 ++++++++++---------- drivers/media/pci/mantis/mantis_pci.c | 2 +- 2 files changed, 11 insertions(+), 11 deletions(-) diff --git a/drivers/media/pci/mantis/mantis_dma.c b/drivers/media/pci/mantis/mantis_dma.c index 4df571ff272b..80c843936493 100644 --- a/drivers/media/pci/mantis/mantis_dma.c +++ b/drivers/media/pci/mantis/mantis_dma.c @@ -52,8 +52,8 @@ int mantis_dma_exit(struct mantis_pci *mantis) mantis->buf_cpu, MANTIS_BUF_SIZE); - pci_free_consistent(mantis->pdev, MANTIS_BUF_SIZE, - mantis->buf_cpu, mantis->buf_dma); + dma_free_coherent(&mantis->pdev->dev, MANTIS_BUF_SIZE, + mantis->buf_cpu, mantis->buf_dma); mantis->buf_cpu = NULL; } @@ -64,8 +64,8 @@ int mantis_dma_exit(struct mantis_pci *mantis) mantis->risc_cpu, MANTIS_RISC_SIZE); - pci_free_consistent(mantis->pdev, MANTIS_RISC_SIZE, - mantis->risc_cpu, mantis->risc_dma); + dma_free_coherent(&mantis->pdev->dev, MANTIS_RISC_SIZE, + mantis->risc_cpu, mantis->risc_dma); mantis->risc_cpu = NULL; } @@ -77,9 +77,9 @@ EXPORT_SYMBOL_GPL(mantis_dma_exit); static inline int mantis_alloc_buffers(struct mantis_pci *mantis) { if (!mantis->buf_cpu) { - mantis->buf_cpu = pci_alloc_consistent(mantis->pdev, - MANTIS_BUF_SIZE, - &mantis->buf_dma); + mantis->buf_cpu = dma_alloc_coherent(&mantis->pdev->dev, + MANTIS_BUF_SIZE, + &mantis->buf_dma, GFP_KERNEL); if (!mantis->buf_cpu) { dprintk(MANTIS_ERROR, 1, "DMA buffer allocation failed"); @@ -92,9 +92,9 @@ static inline int mantis_alloc_buffers(struct mantis_pci *mantis) mantis->buf_cpu, MANTIS_BUF_SIZE); } if (!mantis->risc_cpu) { - mantis->risc_cpu = pci_alloc_consistent(mantis->pdev, - MANTIS_RISC_SIZE, - &mantis->risc_dma); + mantis->risc_cpu = dma_alloc_coherent(&mantis->pdev->dev, + MANTIS_RISC_SIZE, + &mantis->risc_dma, GFP_KERNEL); if (!mantis->risc_cpu) { dprintk(MANTIS_ERROR, 1, diff --git a/drivers/media/pci/mantis/mantis_pci.c b/drivers/media/pci/mantis/mantis_pci.c index 3bfb3e99c93a..9fbce74b00c8 100644 --- a/drivers/media/pci/mantis/mantis_pci.c +++ b/drivers/media/pci/mantis/mantis_pci.c @@ -55,7 +55,7 @@ int mantis_pci_init(struct mantis_pci *mantis) goto fail0; } - err = pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(32)); + err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err != 0) { dprintk(MANTIS_ERROR, 1, "ERROR: Unable to obtain 32 bit DMA <%i>", err); ret = -ENOMEM; -- 2.25.1
