Add dma_debug_init() for ia64

2009-07-17T13:34:57+00:00

The commit 9916219579d078c80377dd3988c2cc213536d868 was supposed to
add CONFIG_DMA_API_DEBUG support to IA64 however I forgot to add
dma_debug_init().

IA64: fix compile error on IA64_DIG_VTD

2009-01-27T14:45:21+00:00

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

2009-01-06T13:06:57+00:00

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.

add dma_get_ops to struct ia64_machine_vector

2009-01-06T13:06:51+00:00

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.

set up dma_ops appropriately

2009-01-06T13:06:50+00:00

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.
