From baa676fcf8d555269bd0a5a2496782beee55824d Mon Sep 17 00:00:00 2001 From: Andrzej Pietrasiewicz Date: Tue, 27 Mar 2012 14:28:18 +0200 Subject: X86 & IA64: adapt for dma_map_ops changes Adapt core x86 and IA64 architecture code for dma_map_ops changes: replace alloc/free_coherent with generic alloc/free methods. Signed-off-by: Andrzej Pietrasiewicz Acked-by: Kyungmin Park [removed swiotlb related changes and replaced it with wrappers, merged with IA64 patch to avoid inter-patch dependences in intel-iommu code] Signed-off-by: Marek Szyprowski Reviewed-by: Arnd Bergmann Acked-by: Tony Luck --- arch/x86/kernel/pci-swiotlb.c | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'arch/x86/kernel/pci-swiotlb.c') diff --git a/arch/x86/kernel/pci-swiotlb.c b/arch/x86/kernel/pci-swiotlb.c index 8f972cbddef0..6c483ba98b9c 100644 --- a/arch/x86/kernel/pci-swiotlb.c +++ b/arch/x86/kernel/pci-swiotlb.c @@ -15,21 +15,30 @@ int swiotlb __read_mostly; static void *x86_swiotlb_alloc_coherent(struct device *hwdev, size_t size, - dma_addr_t *dma_handle, gfp_t flags) + dma_addr_t *dma_handle, gfp_t flags, + struct dma_attrs *attrs) { void *vaddr; - vaddr = dma_generic_alloc_coherent(hwdev, size, dma_handle, flags); + vaddr = dma_generic_alloc_coherent(hwdev, size, dma_handle, flags, + attrs); if (vaddr) return vaddr; return swiotlb_alloc_coherent(hwdev, size, dma_handle, flags); } +static void x86_swiotlb_free_coherent(struct device *dev, size_t size, + void *vaddr, dma_addr_t dma_addr, + struct dma_attrs *attrs) +{ + swiotlb_free_coherent(dev, size, vaddr, dma_addr); +} + static struct dma_map_ops swiotlb_dma_ops = { .mapping_error = swiotlb_dma_mapping_error, - .alloc_coherent = x86_swiotlb_alloc_coherent, - .free_coherent = swiotlb_free_coherent, + .alloc = x86_swiotlb_alloc_coherent, + .free = x86_swiotlb_free_coherent, .sync_single_for_cpu = swiotlb_sync_single_for_cpu, .sync_single_for_device = swiotlb_sync_single_for_device, .sync_sg_for_cpu = swiotlb_sync_sg_for_cpu, -- cgit v1.2.1
