2007-01-24[POWERPC] Add a field for each specific bus to struct pci_controllerIshizaki Kou
Struct pci_controller doesn't prepare for the dependent data of each specific bus. This patch adds private member to struct pci_controller. Signed-off-by: Kou Ishizaki <kou.ishizaki@toshiba.co.jp> Acked-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-12-08[POWERPC] Fix mmap of PCI resource with hack for XBenjamin Herrenschmidt
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.

2006-12-04[POWERPC] Add "parent" struct device for PCI host bridgesBenjamin Herrenschmidt
Add a "parent" struct device to our PCI host bridge data structure so that PCI can be rooted off another device in sysfs. Note that arch/ppc doesn't use it, only arch/powerpc, though it's available for both 32 and 64 bits.

2006-06-15[POWERPC] pcibus_to_node fixesAnton Blanchard
of_node_to_nid returns -1 if the associativity cannot be found. This means pcibus_to_cpumask has to be careful not to pass a negative index into node_to_cpumask. Since pcibus_to_node could be used a lot, and of_node_to_nid is slow (it walks a list doing strcmps), lets also cache the node in the pci_controller struct.

2006-05-24[PATCH] powerpc: remove LogicalSlot from pci_dnStephen Rothwell
As we now store enough information in the device_node. Also the Flags field was not used either, do remove that. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-05-24[PATCH] powerpc: remove Irq from pci_dnStephen Rothwell

2006-05-24[PATCH] powerpc: remove iSeries_Global_Device_ListStephen Rothwell
We can now scan the list of device nodes instead. This also allows us to remove the Device_list member of struct pci_dn. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

26-eeh-partition-endpoint.patch New versions of firmware introduce a new method by which the "partitionable endpoint" (the point at which the pci bus is cut) should be located.

2006-01-09[PATCH] powerpc: sanitize header files for user space includesArnd Bergmann
include/asm-ppc/ had #ifdef __KERNEL__ in all header files that are not meant for use by user space, include/asm-powerpc does not have this yet. This patch gets us a lot closer there. There are a few cases where I was not sure, so I left them out. I have verified that no CONFIG_* symbols are used outside of __KERNEL__ any more and that there are no obvious compile errors when including any of the headers in user space libraries.

2006-01-09[PATCH] powerpc: pci_address_to_pio fixBenjamin Herrenschmidt
This fixes pci_address_to_pio() to return an unsigned long (to be safe) and fixes a bug in the implementation that caused it to return a bogus IO port number Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: export PCI fixup routinelinas
There is code in the RPAPHP directory that is identical to this routine; I'll be removing that code in an upcoming patch, but this patch is needed to expose the function to make it callable. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: Update OF address parsersBenjamin Herrenschmidt
This updates the OF address parsers to return the IO flags indicating the type of address obtained. It also adds a PCI call for converting physical addresses that hit IO space into into IO tokens, and add routines that return the translated addresses into struct resource Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: migrate common PCI hotplug codeLinas Vepstas
23-rpaphp-migrate.patch (parts) This patch moves some pci device add & remove code from the PCI hotplug directory to the arch/powerpc/kernel directory, and cleans it up a tad. The primary reason for this is that the code performs some fairly generic operations that are shared with the PCI error recovery code (living in the arch/powerpc/kernel directory).

2006-01-09[PATCH] powerpc: serial port discovery (#2)Benjamin Herrenschmidt
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.

2005-11-19powerpc: Trivially merge several headers from asm-ppc64 to asm-powerpcPaul Mackerras
For these, I have just done the lame-o merge where the file ends up looking like: #ifndef CONFIG_PPC64 #include <asm-ppc/foo.h> #else ... contents from asm-ppc64/foo.h #endif so nothing has changed, really, except that we reduce include/asm-ppc64 a bit more.
