* powerpc: Remove arch/ppc and include/asm-ppcPaul Mackerras2008-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | All the maintained platforms are now in arch/powerpc, so the old arch/ppc stuff can now go away.

* iomap: fix 64 bits resources on 32 bitsBenjamin Herrenschmidt2008-04-29
| | | | | | | | | | | | | | Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency.

* PCI: ppc: use generic pci_enable_resources()Bjorn Helgaas2008-04-21
| | | | | | | | | | | | | | Use the generic pci_enable_resources() instead of the arch-specific code. Unlike this arch-specific code, the generic version: - checks PCI_NUM_RESOURCES (11), not 6, resources - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set - skips ROM resources unless IORESOURCE_ROM_ENABLE is set - checks for resource collisions with "!r->parent", not IORESOURCE_UNSET Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* PCI: Use a weak symbol for the empty version of pcibios_add_platform_entries()Michael Ellerman2007-07-11
| | | | | | | | | | | | | | | 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.

* [POWERPC] Fix mmap of PCI resource with hack for XBenjamin Herrenschmidt2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc version of pci_resource_to_user() and associated hooks used by /proc/bus/pci and /sys/bus/pci mmap have been broken for some time on machines that don't have a 1:1 mapping of devices (basically on non-PowerMacs) and have PCI devices above 32 bits. This attempts to fix it as well as possible. The rule is supposed to be that pci_resource_to_user() always converts the resources back into a BAR values since that's what the /proc interface was supposed to deal with. However, for X to work on platforms where PCI MMIO is not mapped 1:1, it became a habit of platforms like powerpc to pass "fixed up" values there since X expects to be able to use values from /proc/bus/pci/devices as offsets to mmap of /dev/mem... So we keep that contraption here, causing also /sys/*/resource to expose fully absolute MMIO addresses instead of BAR values, which is ugly, but should still work as long as those are only used to calculate alignment within a page. X is still broken when built 32 bits on machines where PCI MMIO can be above 32-bit space unfortunately.

* [PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHMChristoph Lameter2006-06-25
| | | | | | | | | | | | | | | | | Remove VM_LOCKED before remap_pfn range from device drivers and get rid of VM_SHM. remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not place pages on the LRU. The pages are therefore never subject to swap anyways. Remove all the vm_flags settings before calling remap_pfn_range. After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

* ppc: Remove CHRP, POWER3 and POWER4 support from arch/ppcPaul Mackerras2006-03-27
| | | | | | | | | | | | | | | | | | | 32-bit CHRP machines are now supported only in arch/powerpc, as are all 64-bit PowerPC processors. This means that we don't use Open Firmware on any platform in arch/ppc any more. This makes PReP support a single-platform option like every other platform support option in arch/ppc now, thus CONFIG_PPC_MULTIPLATFORM is gone from arch/ppc. CONFIG_PPC_PREP is the option that selects PReP support and is generally what has replaced CONFIG_PPC_MULTIPLATFORM within arch/ppc. _machine is all but dead now, being #defined to 0. Updated Makefiles, comments and Kconfig options generally to reflect these changes. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] ppc: Remove powermac support from ARCH=ppcPaul Mackerras2006-01-15
| | | | | | | | | | | This makes it possible to build kernels for PReP and/or CHRP with ARCH=ppc by removing the (non-building) powermac support. It's now also possible to select PReP and CHRP independently. Powermac users should now build with ARCH=powerpc instead of ARCH=ppc. (This does mean that it is no longer possible to build a 32-bit kernel for a G5.) Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] powerpc: serial port discovery (#2)Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | This moves the discovery of legacy serial ports to a separate file, makes it common to ppc32 and ppc64, and reworks it to use the new OF address translators to get to the ports early. This new version can also detect some PCI serial cards using legacy chips and will probably match those discovered port with the default console choice. Only ppc64 gets udbg still yet, unifying udbg isn't finished yet. It also adds some speed-probing code to udbg so that the default console can come up at the same speed it was set to by the firmware.

* [PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addressesRoland Dreier2005-10-29
| | | | | | | | | | | | | | | | | | Change the phys_mem_access_prot() function to take a pfn instead of an address. This allows mmap64() to work on /dev/mem for addresses above 4G on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no need to convert to an address; in fact, it's actively bad, since the conversion can overflow when the address is above 4G. Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an address by directly comparing to max_pfn. Working with max_pfn instead of high_memory fixes page_is_ram() to give the right answer for highmem pages.

| | | | | | | | | | | | | | | 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() ?).

| | | | | | | | | | | | | | | | | | | | | | | This is an updated version of Ben's fix-pci-mmap-on-ppc-and-ppc64.patch which is in 2.6.12-rc4-mm1. It fixes the patch to work on PPC iSeries, removes some debug printks at Ben's request, and incorporates your fix-pci-mmap-on-ppc-and-ppc64-fix.patch also. Originally from Benjamin Herrenschmidt <benh@kernel.crashing.org> This patch was discussed at length on linux-pci and so far, the last iteration of it didn't raise any comment. It's effect is a nop on architecture that don't define the new pci_resource_to_user() callback anyway. It allows architecture like ppc who put weird things inside of PCI resource structures to convert to some different value for user visible ones. It also fixes mmap'ing of IO space on those archs.

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!
