Hi Ingo, This branch allows a Xen dom0 kernel to access PCI devices properly. Mostly this involves making sure that memory being used for DMA is both logically contigious in the kernel's pseudo-physical memory and physically contigious in machine memory. Again, this is pretty much unchanged from the last time I posted it. The following changes since commit 0c96e43850feb7c7c4a4950f24533491fbd63b5a: Jeremy Fitzhardinge (1): xen: checkpatch cleanups are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git xen-tip/dom0/pci Alex Nixon (7): xen: Don't disable the I/O space xen: Allow unprivileged Xen domains to create iomap pages Xen: Rename the balloon lock xen: Add xen_create_contiguous_region x86/PCI: Clean up pci_cache_line_size x86/PCI: Enable scanning of all pci functions Xen/x86/PCI: Add support for the Xen PCI subsytem Jeremy Fitzhardinge (4): xen/swiotlb: use dma_alloc_from_coherent to get device coherent memory x86/pci: make sure _PAGE_IOMAP it set on pci mappings xen/pci: clean up Kconfig a bit xen: checkpatch cleanups arch/x86/Kconfig | 4 + arch/x86/include/asm/io.h | 2 + arch/x86/include/asm/pci.h | 8 +- arch/x86/include/asm/pci_x86.h | 2 + arch/x86/include/asm/xen/iommu.h | 12 ++ arch/x86/kernel/pci-dma.c | 3 + arch/x86/pci/Makefile | 1 + arch/x86/pci/common.c | 18 ++- arch/x86/pci/i386.c | 3 + arch/x86/pci/init.c | 6 + arch/x86/pci/xen.c | 51 +++++++ arch/x86/xen/Kconfig | 2 + arch/x86/xen/enlighten.c | 6 +- arch/x86/xen/mmu.c | 225 ++++++++++++++++++++++++++++++- arch/x86/xen/setup.c | 3 - drivers/pci/Makefile | 2 + drivers/pci/xen-iommu.c | 279 ++++++++++++++++++++++++++++++++++++++ drivers/xen/balloon.c | 15 +-- include/xen/interface/memory.h | 50 +++++++ include/xen/xen-ops.h | 6 + 20 files changed, 671 insertions(+), 27 deletions(-) create mode 100644 arch/x86/include/asm/xen/iommu.h create mode 100644 arch/x86/pci/xen.c create mode 100644 drivers/pci/xen-iommu.c Thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
