[POWERPC] Add new interrupt mapping core and change platforms to use it

2006-07-03T11:36:01Z

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. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[PATCH] powerpc: node-aware dma allocations

2006-06-09T11:24:01Z

Make sure dma_alloc_coherent allocates memory from the local node. This is important on Cell where we avoid going through the slow cpu interconnect. Note: I could only test this patch on Cell, it should be verified on some pseries machine by those that have the hardware. Signed-off-by: Christoph Hellwig Signed-off-by: Paul Mackerras

[PATCH] powerpc: the iSeries vio lan driver changed device type

2006-05-19T05:02:24Z

So the IOMMU table building code needs to match. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] powerpc: pseries: Use generic dma-window parsing function

2006-05-19T05:02:23Z

Change the pseries iommu init code to use the new of_parse_dma_window() to parse the ibm,dma-window and ibm,my-dma-window properties of pci and virtual device nodes. Also, clean up vio_build_iommu_table() a little. Tested on pseries, with both vio and pci devices. Signed-off-by: Jeremy Kerr Acked-by: Olof Johansson Signed-off-by: Paul Mackerras

[PATCH] powerpc: merge the rest of the vio code

[PATCH] powerpc: use a common vio_match_device routine

2006-04-29T08:02:01Z

This requires the compatible properties having vaules that are empty strings instead of just being empty properties. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] powerpc: use the device tree for the iSeries vio bus probe

2006-04-29T08:02:00Z

As an added bonus, since every vio_dev now has a device_node associated with it, hotplug now works. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] powerpc: IOMMU support for honoring dma_mask

2006-04-21T12:28:55Z

Some devices don't support full 32-bit DMA address space, which we currently assume. Add the required mask-passing to the IOMMU allocators. Signed-off-by: Olof Johansson Signed-off-by: Paul Mackerras
