sparc, sparc64: use arch/sparc/include

2008-07-27T21:00:59+00:00

The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build. And a small fixlet to pick up the correct unistd.h from sparc64 code. Signed-off-by: Sam Ravnborg

sparc: join the remaining header files

2008-07-18T04:55:51+00:00

With this commit all sparc64 header files are moved to asm-sparc. The remaining files (71 files) were too different to be trivially merged so divide them up in a _32.h and a _64.h file which are both included from the file with no bit size. The following script were used: cd include FILES=`wc -l asm-sparc64/*h | grep -v '^ 1' | cut -b 20-` for FILE in ${FILES}; do echo $FILE: BASE=`echo $FILE | cut -d '.' -f 1` FN32=${BASE}_32.h FN64=${BASE}_64.h GUARD=___ASM_SPARC_`echo $BASE | tr '-' '_' | tr [:lower:] [:upper:]`_H git mv asm-sparc/$FILE asm-sparc/$FN32 git mv asm-sparc64/$FILE asm-sparc/$FN64 echo git mv done printf "#ifndef %s\n" $GUARD > asm-sparc/$FILE printf "#define %s\n" $GUARD >> asm-sparc/$FILE printf "#if defined(__sparc__) && defined(__arch64__)\n" >> asm-sparc/$FILE printf "#include \n" $FN64 >> asm-sparc/$FILE printf "#else\n" >> asm-sparc/$FILE printf "#include \n" $FN32 >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE git add asm-sparc/$FILE echo new file done printf "#include \n" $FILE > asm-sparc64/$FILE git add asm-sparc64/$FILE echo sparc64 file done done The guard contains three '_' to avoid conflict with existing guards. In additing the two Kbuild files are emptied to avoid breaking headers_* targets. We will reintroduce the exported header files when the necessary kbuild changes are merged.

[SPARC64]: Implement pci_resource_to_user()

2007-12-27T03:33:46+00:00

This makes libpciaccess able to mmap() resources of the device properly. Signed-off-by: David S. Miller

[SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling.

2007-07-30T07:27:34+00:00

Fully unify all of the DMA ops so that subordinate bus types to the DMA operation providers (such as ebus, isa, of_device) can work transparently. Basically, we just make sure that for every system device we create, the dev->archdata 'iommu' and 'stc' fields are filled in. Then we have two platform variants of the DMA ops, one for SUN4U which actually programs the real hardware, and one for SUN4V which makes hypervisor calls. This also fixes the crashes in parport_pc on sparc64, reported by Meelis Roos. Signed-off-by: David S. Miller

PCI: remove pci_dac_dma_... APIs

2007-07-11T23:02:11+00:00

Based on replies to a respective query, remove the pci_dac_dma_...() APIs (except for pci_dac_dma_supported() on Alpha, where this function is used in non-DAC PCI DMA code).

PCI: Use a weak symbol for the empty version of pcibios_add_platform_entries()

2007-07-11T23:02:07+00:00

I'm not sure if this is going to fly, weak symbols work on the compilers I'm using, but whether they work for all of the affected architectures I can't say. I've cc'ed as many arch maintainers/lists as I could find. But assuming they do, we can use a weak empty definition of pcibios_add_platform_entries() to avoid having an empty definition on every arch.

PCI: Use pci_generic_prep_mwi on sparc64

2006-12-01T22:36:57+00:00

The setting of the CACHE_LINE_SIZE register in sparc64's pci initialisation code isn't quite adequate as the device may have incompatible requirements. The generic code tests for this, so switch sparc64 over to using it. Since sparc64 has different L1 cache line size and PCI cache line size, it would need to override the generic code like i386 and ia64 do. We know what the cache line size is at compile time though, so introduce a new optional constant PCI_CACHE_LINE_BYTES.

[SPARC64]: Respect gfp_t argument to dma_alloc_coherent().

2006-05-23T09:07:22+00:00

Using asm-generic/dma-mapping.h does not work because pushing the call down to pci_alloc_coherent() causes the gfp_t argument of dma_alloc_coherent() to be ignored. Fix this by implementing things directly, and adding a gfp_t argument we can use in the internal call down to the PCI DMA implementation of pci_alloc_coherent(). This fixes massive memory corruption when using the sound driver layer, which passes things like __GFP_COMP down into these routines and (correctly) expects that to work. Signed-off-by: David S.
