Date: Fri, 20 Mar 2009 11:25:10 +0800 From: Yu Zhao <yu.zhao@...el.com> To: jbarnes@...tuousgeek.org Cc: linux-pci@...r.kernel.org, kvm@...r.kernel.org, linux-kernel@...r.kernel.org, Yu Zhao <yu.zhao@...el.com> Subject: [PATCH v12 0/8] PCI: Linux kernel SR-IOV support Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. SR-IOV specification can be found at: http://www.pcisig.com/members/downloads/specifications/iov/sr-iov1.0_11Sep07.pdf (it requires membership.) Devices that support SR-IOV are available from following vendors: http://download.intel.com/design/network/ProdBrf/320025.pdf http://www.myri.com/vlsi/Lanai_Z8ES_Datasheet.pdf http://www.neterion.com/products/pdfs/X3100ProductBrief.pdf The patches to enable the SR-IOV capability of Intel 82576 NIC are available at (a.k.a Physical Function driver): http://patchwork.kernel.org/patch/8063/ http://patchwork.kernel.org/patch/8064/ http://patchwork.kernel.org/patch/8065/ http://patchwork.kernel.org/patch/8066/ And the driver for Intel 82576 Virtual Function are available at: http://patchwork.kernel.org/patch/11029/ http://patchwork.kernel.org/patch/11028/ Major changes from v11 to v12: 1, fix using garbage entry pointer after the list_for_each (Matthew Wilcox) 2, use #ifdef around SR-IOV structure in the pci_dev (Matthew Wilcox) 3, enhance the Kconfig help text for the SR-IOV (Matthew Wilcox) v10 to v11: 1, use pci_setup_device() to setup Virtual Function (Matthew Wilcox) 2, various coding style fixes (Matthew Wilcox) 3, wording and grammar fixes (Randy Dunlap) v9 -> v10: 1, minor fix in pci_restore_iov_state(). 2, respin against the latest tree. v8 -> v9: 1, put a might_sleep() into SR-IOV API which sleeps (Andi Kleen) 2, block user config accesses before clearing VF Enable bit (Matthew Wilcox) Yu Zhao (8): PCI: initialize and release SR-IOV capability PCI: restore saved SR-IOV state PCI: reserve bus range for SR-IOV device PCI: centralize device setup code PCI: add SR-IOV API for Physical Function driver PCI: handle SR-IOV Virtual Function Migration PCI: document SR-IOV sysfs entries PCI: manual for SR-IOV user and driver developer Documentation/ABI/testing/sysfs-bus-pci | 27 ++ Documentation/DocBook/kernel-api.tmpl | 1 + Documentation/PCI/pci-iov-howto.txt | 99 +++++ drivers/pci/Kconfig | 10 + drivers/pci/Makefile | 2 + drivers/pci/iov.c | 680 +++++++++++++++++++++++++++++++ drivers/pci/pci.c | 8 + drivers/pci/pci.h | 53 +++ drivers/pci/probe.c | 86 +++-- include/linux/pci.h | 34 ++ include/linux/pci_regs.h | 33 ++ 11 files changed, 994 insertions(+), 39 deletions(-) create mode 100644 Documentation/PCI/pci-iov-howto.txt create mode 100644 drivers/pci/iov.c -- 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/
