It goes to pci-dma.c, and is removed from the arch-specific files. Signed-off-by:

i386 implements the declare coherent memory API, and x86_64 does not it is reflected in pieces of dma_alloc_coherent and dma_free_coherent. Those pieces are isolated in separate functions, that are declared as empty macros in x86_64. This way we can make the code the same. Signed-off-by:

They are placed in an ifdef, since they are i386 specific the structure definition goes to dma-mapping.h. Signed-off-by:

we merge the iommu initialization parameters in pci-dma.c Nice thing, that both architectures at least recognize the same parameters. usedac i386 parameter is marked for deprecation Signed-off-by:

Glauber Costa authored
The code for both arches are very similar, so this patch merge them. Signed-off-by:

via_no_dac provides a fixup that is the same for both architectures. Move it to pci-dma.c. Signed-off-by:

This patch moves the bootmem functions, that are largely x86_64-specific into pci-dma.c. The code goes inside an ifdef. Signed-off-by:

initcalls that triggers the various possibiities for dma subsys are moved to pci-dma.c. Signed-off-by:

merge pci-base_32.c and pci-nommu_64.c into pci-nommu.c Their code were made the same, so now they can be merged. Signed-off-by:

Move dma_ops structure definition to pci-dma.c, where it belongs. Signed-off-by:

This is done to get the code closer to x86_64. Signed-off-by:

In the very same way i386 do, we use WARN_ON functions in map_simple and map_sg. Signed-off-by:
-
Glauber Costa authored
To make the code usable in i386, where we have high memory mappings, we drop te virt_to_bus(sg_virt()) construction in favour of sg_phys. Signed-off-by:

This patch adds flush_write_buffers() in some functions of pci-nommu_64.c They are added anywhere i386 would also have it. This is not a problem for x86_64, since flush_rite_buffers() an nop for it. Signed-off-by:

This patch implements mapping_error for pci-nommu_64.c. It takes care to keep the same compatible behaviour it already had. Although this file is not (yet) used for i386, we introduce the i386 version here. Again, care is taken, even at the expense of an ifdef, to keep the same behaviour inconditionally. Signed-off-by:
-

This functions are now called conditionally on their existence in the struct. So just delete them, instead of keeping an empty implementation. Signed-off-by:

This patch introduces pci-dma.c, a common file for pci dma between i386 and x86_64. As a start, dma_set_mask() is the same between architectures, and is placed there. Signed-off-by:

They just need to be exported like on x86_64. dma_supported() and dma_set_mask() were previously inlined, but are now moved to pci-dma_32.c. Since they're used by various drivers, they need to be exported. Signed-off-by:

define it conditionally to i386. Signed-off-by:

Glauber Costa authored
We provide a map_error function in pci-base_32.c to make sure i386 keeps with the same behaviour it used to. Signed-off-by:

It's initially 0, since we don't expect any DMA there. Signed-off-by:

Glauber Costa authored
Do it instead of using the conservative approach we're currently doing. This is the way x86_64 does, and this patch makes this piece of code the same between them, ready to be integrated. Signed-off-by:
-
Glauber Costa authored
This is the way x86_64 does, so this make them equal. They have to be extern now in the header, and the extern definition is moved to the common dma-mapping.h header. Signed-off-by:

They are similar enough to do this move. the macro version is ugly, and we use inline functions instead. Signed-off-by:

they are the same between architectures. (except for the fact that x86_64 has duplicate code) move them to dma-mapping.h Signed-off-by:

i386 base does not need it, so it gets an empty function. Signed-off-by:
-
Glauber Costa authored
That's already the name of the game for x86_64. For i386, we add a pci-base_32.c, that will hold the default operations. The function call itself goes through dma-mapping.h , the common header Signed-off-by:
