Linux-2.6.12-rc2 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!

[PATCH] swiotlb: file header comments Change comment at top of swiotlb.c to reflect that the code is shared with EM64T (i.e. Intel x86_64).

[IA64] more robust zx1/sx1000 machvec support Machine vector selection has always been a bit of a hack given how early in system boot it needs to be done. Services like ACPI namespace are not available and there are non-trivial problems to moving them to early boot. However, there's no reason we can't change to a different machvec later in boot when the services we need are available. By adding a entry point for later initialization of the swiotlb, we can add an error path for the hpzx1 machevec initialization and fall back to the DIG machine vector if IOMMU hardware isn't found in the system. Since ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a contiguous range from the slab for bounce buffer usage.

[PATCH] swiotlb: support syncing DMA_BIDIRECTIONAL mappings The current implementation of sync_single in swiotlb.c chokes on DMA_BIDIRECTIONAL mappings. This patch adds the capability to sync those mappings, and optimizes other syncs by accounting for the sync target (i.e. cpu or device) in addition to the DMA direction of the mapping.

[IA64, X86_64] fix swiotlb sizing Fix swiotlb sizing to match what the comments and the kernel parameters documentation indicate. Given a default 16k page size kernel (ia64) and a 2k swiotlb page size, we're off by a multiple of 8 trying to size the swiotlb. When specified on the boot line, the swiotlb is made 8x bigger than requested. When left to the default value, it's 8x smaller than the comments indicate. For x86_64 the multiplier would be 2x. The patch below fixes this. Now, what's a good default swiotlb size? Apparently we don't really need 64MB.

[PATCH] x86_64: Use function pointers to call DMA mapping functions AK: I hacked Muli's original patch a lot and there were a lot of changes - all bugs are probably to blame on me now. There were also some changes in the fall back behaviour for swiotlb - in particular it doesn't try to use GFP_DMA now anymore. Also all DMA mapping operations use the same core dma_alloc_coherent code with proper fallbacks now. And various other changes and cleanups. Known problems: iommu=force swiotlb=force together breaks needs more testing. This patch cleans up x86_64's DMA mapping dispatching code. Right now we have three possible IOMMU types: AGP GART, swiotlb and nommu, and in the future we will also have Xen's x86_64 swiotlb and other HW IOMMUs for x86_64. In order to support all of them cleanly, this patch: - introduces a struct dma_mapping_ops with function pointers for each of the DMA mapping operations of gart (AMD HW IOMMU), swiotlb (software IOMMU) and nommu (no IOMMU). - gets rid of: if (swiotlb) return swiotlb_xxx(); - PCI_DMA_BUS_IS_PHYS is now checked against the dma_ops being set This makes swiotlb faster by avoiding double copying in some cases.

[PATCH] Fix swiotlb pci_map_sg error handling The overflow checking condition in lib/swiotlb.c was wrong. It would first run a NULL pointer through virt_to_phys before testing it. Since pci_map_sg overflow is not that uncommon and causes data corruption (including broken file systems) when not properly detected I think it's better to fix it in 2.6.15.

Linux-2.6.12-rc2 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!
