This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

This patch slightly reworks the new irq code to fix a small design error. I removed the passing of the trigger to the map() calls entirely, it was not a good idea to have one call do two different things. It also fixes a couple of corner cases. Mapping a linux virtual irq to a physical irq now does only that. Setting the trigger is a different action which has a different call. The main changes are: - I no longer call host->ops->map() for an already mapped irq, I just return the virtual number that was already mapped. It was called before to give an opportunity to change the trigger, but that was causing issues as that could happen while the interrupt was in use by a device, and because of the trigger change, map would potentially muck around with things in a racy way. That was causing much burden on a given's controller implementation of map() to get it right. This is much simpler now. map() is only called on the initial mapping of an irq, meaning that you know that this irq is _not_ being used. You can initialize the hardware if you want (though you don't have to). - Controllers that can handle different type of triggers (level/edge/etc...) now implement the standard irq_chip->set_type() call as defined by the generic code. That means that you can use the standard set_irq_type() to configure an irq line manually if you wish or (though I don't like that interface), pass explicit trigger flags to request_irq() as defined by the generic kernel interfaces. Also, using those interfaces guarantees that your controller set_type callback is called with the descriptor lock held, thus providing locking against activity on the same interrupt (including mask/unmask/etc...) automatically. A result is that, for example, MPIC's own map() implementation calls irq_set_type(NONE) to configure the hardware to the default triggers. - To allow the above, the irq_map array entry for the new mapped interrupt is now set before map() callback is called for the controller. - The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function for mapping interrupts from the device-tree now also call the separate set_irq_type(), and only does so if there is a change in the trigger type. - While I was at it, I changed pci_read_irq_line() (which is the helper I would expect most archs to use in their pcibios_fixup() to get the PCI interrupt routing from the device tree) to also handle a fallback when the DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an interrupt number from the device. That number is then mapped using the default controller, and the trigger is set to level low. That default behaviour works for several platforms that don't have a proper interrupt tree like Pegasos. If it doesn't work for your platform, then either provide a proper interrupt tree from the firmware so that fallback isn't needed, or don't call pci_read_irq_line() - Add back a bit that got dropped by my main rework patch for properly clearing pending IPIs on pSeries when using a kexec Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.

This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

This adds some very basic support for the new machines, including the Quad G5 (tested), and other new dual core based machines and iMac G5 iSight (untested). This is still experimental ! There is no thermal control yet, there is no proper handing of MSIs, etc.. but it boots, I have all 4 cores up on my machine. Compared to the previous version of this patch, this one adds DART IOMMU support for the U4 chipset and thus should work fine on setups with more than 2Gb of RAM.

I discovered that in some cases (PowerMac for example) we wouldn't properly map the PCI IO space on recent kernels. In addition, the code for initializing PCI host bridges was scattered all over the place with some duplication between platforms. This patch fixes the problem and does a small cleanup by creating a pcibios_alloc_controller() in pci_64.c that is similar to the one in pci_32.c (just takes an additional device node argument) that takes care of all the grunt allocation and initialisation work. It should work for both boot time and dynamically allocated PHBs. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: NPaul Mackerras <paulus@samba.org>

phbs_remap_io(), which maps the PCI IO space into the kernel virtual space, is called too early on powermac, and thus doesn't work. This fixes it by removing the call from all platforms and putting it back into the ppc64 common code where it belongs, after the actual probing of the bus. That means that before that call, only the ISA IO space (if any) is mapped, any PIO access (from quirks for example) will fail. This happens not to be a problem for now, but we'll have to rework that code if it becomes one in the future.

This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.

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!
