Date: Tue, 31 Mar 2009 15:52:06 -0700 From: Jeremy Fitzhardinge <jeremy@...p.org> To: FUJITA Tomonori <fujita.tomonori@....ntt.co.jp> Cc: the arch/x86 maintainers <x86@...nel.org>, Ingo Molnar <mingo@...e.hu>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: [PATCH] swiotlb updates for Xen dom0 Hi Fujita, This series adds Xen support to x86 swiotlb. This is mostly a matter of adding some Xen code into the existing hooks in pci-swiotlb_64.c: - swiotlb_alloc_boot - swiotlb_arch_range_needs_mapping - swiotlb_phys_to_bus/bus_to_phys These hooks are conditional on xen_pv_domain(), which compiles to a constant 0 when CONFIG_XEN is not enabled (and is a simple variable read when it is). All the Xen-specific code is in xen-iommu.c. This series is just the patches which touch lib/swiotlb.c or pci-swiotlb_64.c. You can see them with more context in: git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git for-linus/xen/dom0/swiotlb Thanks, J arch/x86/kernel/pci-swiotlb_64.c | 31 ++++++++++++++++- arch/x86/xen/Kconfig | 1 drivers/pci/xen-iommu.c | 68 ++++++++++++++++++++++++++++++++++++--- include/xen/swiotlb.h | 38 +++++++++++++++++++++ lib/swiotlb.c | 3 + 5 files changed, 133 insertions(+), 8 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
