treewide: Constify most dma_map_ops structures

2017-01-24T17:23:35Z

Most dma_map_ops structures are never modified. Constify these structures such that these can be write-protected.

[IA64] Fix warning in dma-mapping.c

Add dma_debug_init() for ia64

2009-07-17T13:34:57Z

The commit 9916219579d078c80377dd3988c2cc213536d868 was supposed to add CONFIG_DMA_API_DEBUG support to IA64 however I forgot to add dma_debug_init(). Signed-off-by: fujita Acked-by: Fenghua Yu

IA64: fix compile error on IA64_DIG_VTD

2009-01-27T14:45:21Z

This moves iommu_detected to arch/ia64/kernel/dma-mapping.c from arch/ia64/kernel/pci-swiotlb.c to fix the following error on on IA64_DIG_VTD: arch/ia64/kernel/built-in.o: In function `pci_iommu_init': pci-dma.c:(.init.text+0xa021): undefined reference to `iommu_detected' pci-dma.c:(.init.text+0xa030): undefined reference to `iommu_detected' drivers/built-in.o: In function `detect_intel_iommu': (.init.text+0x11c0): undefined reference to `iommu_detected' drivers/built-in.o: In function `detect_intel_iommu': (.init.text+0x11e1): undefined reference to `iommu_detected' iommu_detected is used to handle IOMMUs so I guess that arch/ia64/kernel/dma-mapping.c is ok (there might be a better place for it though).

x86, ia64: convert to use generic dma_map_ops struct

2009-01-06T13:06:57Z

This converts X86 and IA64 to use include/linux/dma-mapping.h. It's a bit large but pretty boring. The major change for X86 is converting 'int dir' to 'enum dma_data_direction dir' in DMA mapping operations. The major changes for IA64 is using map_page and unmap_page instead of map_single and unmap_single. Signed-off-by: FUJITA Tomonori Acked-by: Tony Luck Signed-off-by: Ingo Molnar

add dma_get_ops to struct ia64_machine_vector

2009-01-06T13:06:51Z

This adds dma_get_ops hook to struct ia64_machine_vector. We use dma_get_ops() in arch/ia64/kernel/dma-mapping.c, which simply returns the global dma_ops. This is for removing hwsw_dma_ops. Signed-off-by: FUJITA Tomonori Acked-by: Tony Luck Signed-off-by: Ingo Molnar

set up dma_ops appropriately

2009-01-06T13:06:50Z

This patch introduces a global pointer, dma_ops, which points to an appropriate dma_mapping_ops that the kernel should use. This is a common way to handle multiple dma_mapping_ops (X86, POWER, and SPARC). dma_ops is set in platform_dma_init. We also set it by hand where machvec_init is callev via subsys_initcall. - IA64_DIG_VTD uses vtd_dma_ops. - IA64_HP_ZX1 uses sba_dma_ops. - IA64_HP_ZX1_SWIOTLB uses hwsw_dma_ops. - IA64_SGI_SN2 uses sn_dma_ops. - The rest use swiotlb_dma_ops.
