powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

powerpc/dma: implement new dma_map_attrs() interfaces

2008-07-09T06:30:43+00:00

Update powerpc to use the new dma_*map*_attrs() interfaces. In doing so update struct dma_mapping_ops to accept a struct dma_attrs and propagate these changes through to all users of the code (generic IOMMU and the 64bit DMA code, and the iseries and ps3 platform code). The old dma_*map_*() interfaces are reimplemented as calls to the corresponding new interfaces.

powerpc/dma: Add struct iommu_table argument to iommu_map_sg()

2008-07-09T06:30:43+00:00

Make iommu_map_sg take a struct iommu_table. It did so before commit 740c3ce66700640a6e6136ff679b067e92125794 (iommu sg merging: ppc: make iommu respect the segment size limits). This stops the function looking in the archdata.dma_data for the iommu table because in the future it will be called with a device that has no table there. This also has the nice side effect of making iommu_map_sg() match the other map functions. Signed-off-by: Mark Nelson Signed-off-by: Arnd Bergmann Signed-off-by: Benjamin Herrenschmidt

iommu sg: powerpc: convert iommu to use the IOMMU helper

2008-02-05T17:44:11+00:00

This patch converts PPC's IOMMU to use the IOMMU helper functions. The IOMMU doesn't allocate a memory area spanning LLD's segment boundary anymore. iseries_hv_alloc and iseries_hv_map don't have proper device struct. 4GB boundary is used for them.

[POWERPC] iommu_free_table doesn't need the device_node

2007-12-11T02:41:33+00:00

It only needs the iommu_table address. It also makes use of the node name to print error messages. So just pass it the things it needs. This reduces the places that know about the pci_dn by one. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

remove asm/bitops.h includes

2007-10-19T18:53:41+00:00

remove asm/bitops.h includes including asm/bitops directly may cause compile errors. don't include it and include linux/bitops instead. next patch will deny including asm header directly. Cc: Adrian Bunk Signed-off-by: Jiri Slaby Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[POWERPC] Cell iommu support

2006-12-04T09:39:02+00:00

This patch adds full cell iommu support (and iommu disabled mode). It implements mapping/unmapping of iommu pages on demand using the standard powerpc iommu framework. It also supports running with iommu disabled for machines with less than 2GB of memory. (The default is off in that case, though it can be forced on with the kernel command line option iommu=force).
