* PCI: collapse pcibios_resource_to_busBjorn Helgaas2012-02-231-2/+0
| | | | | | | Everybody uses the generic pcibios_resource_to_bus() supplied by the core now, so remove the ARCH_HAS_GENERIC_PCI_OFFSETS used during conversion. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
* PCI: add generic pcibios_resource_to_bus()Bjorn Helgaas2012-02-231-23/+1
| | | | | | | | | | | | | | | | | This replaces the generic versions of pcibios_resource_to_bus() and pcibios_bus_to_resource() in asm-generic/pci.h with versions that use pci_resource_to_bus() and pci_bus_to_resource(). The replacements are equivalent except that they can apply host bridge window offsets when the arch has supplied them by using pci_add_resource_offset(). Each arch can convert to using pci_add_resource_offset() individually by removing its device resource fixups from pcibios_fixup_bus() and supplying ARCH_HAS_GENERIC_PCI_OFFSETS. ARCH_HAS_GENERIC_PCI_OFFSETS can be removed after all have converted. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
* PCI: remove pcibios_scan_all_fns()Alex Chiang2009-09-091-1/+12
| | | | | | | | | | | | | | | | | | | | | | | This was #define'd as 0 on all platforms, so let's get rid of it. This change makes pci_scan_slot() slightly easier to read.

* asm-generic: make pci.h usable directlyArnd Bergmann2009-06-111-0/+8
| | | | | | | | | | Some generic code is using the horribly misnamed PCI_DMA_BUS_IS_PHYS from asm/pci.h. This makes sure that an architecture without PCI support does not have to define this itself but can rely on the asm-generic version.

* [PATCH] Make sparc64 use setup-res.cDavid S. Miller2005-09-081-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were three changes necessary in order to allow sparc64 to use setup-res.c: 1) Sparc64 roots the PCI I/O and MEM address space using parent resources contained in the PCI controller structure. I'm actually surprised no other platforms do this, especially ones like Alpha and PPC{,64}. These resources get linked into the iomem/ioport tree when PCI controllers are probed. So the hierarchy looks like this: iomem --| PCI controller 1 MEM space --| device 1 device 2 etc. PCI controller 2 MEM space --| ... ioport --| PCI controller 1 IO space --| ... PCI controller 2 IO space --| ... You get the idea. The drivers/pci/setup-res.c code allocates using plain iomem_space and ioport_space as the root, so that wouldn't work with the above setup. So I added a pcibios_select_root() that is used to handle this. It uses the PCI controller struct's io_space and mem_space on sparc64, and io{port,mem}_resource on every other platform to keep current behavior. 2) quirk_io_region() is buggy. It takes in raw BUS view addresses and tries to use them as a PCI resource. pci_claim_resource() expects the resource to be fully formed when it gets called. The sparc64 implementation would do the translation but that's absolutely wrong, because if the same resource gets released then re-claimed we'll adjust things twice. So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource() conversion before passing it on to pci_claim_resource(). 3) I was mistakedly __init'ing the function methods the PCI controller drivers provide on sparc64 to implement some parts of these routines. This was, of course, easy to fix. So we end up with the following, and that nasty SPARC64 makefile ifdef in drivers/pci/Makefile is finally zapped. Signed-off-by: David S.

* [PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski2005-08-041-0/+8
| | | | | | | | | | | | | | | In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+34
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
