Tsirkin" , Knut Omang , "Richard W.M. Jones" , Alex Williamson , "Gonglei (Arei)" , Jan Kiszka , Paolo Bonzini , Dotan Barak , Richard Henderson This patch set implements generic support for SR/IOV as an extension to the core PCIe functionality, similar to the way other capabilities such as AER is implemented. There is no implementation of any device that provides SR/IOV support included, but I have implemented a test example which can be found together with this patch set here: git://github.com/knuto/qemu.git sriov_patches_v4 Testing with the example device was documented here: http://lists.nongnu.org/archive/html/qemu-devel/2014-08/msg05110.html Changes since v3: - Reworked 'pci: Update pci_regs header' to merge kernel version improvements with the current qemu version instead of copying from the kernel version. Changes since v2: - Rebased onto 090d0bfd - Un-qdev'ified - avoids issues when resetting NUM_VFS - Fixed handling of vf_offset/vf_stride Changes since v1: - Rebased on top of latest master, eliminating prereqs. - Implement proper support for VF_STRIDE, VF_OFFSET and SUP_PGSIZE Time better spent fixing it than explaining what the previous limitations were. - Added new first patch to fix pci bug related to this - Split out patch to pci_default_config_write to a separate patch 2 to highlight bug fix. - Refactored out logic into new source files hw/pci/pcie_sriov.c include/hw/pci/pcie_sriov.h similar to pcie_aer.c/h. - Rename functions and introduce structs to better separate pf and vf functionality. - Replaced is_vf member with pci_is_vf() function abstraction - Fix numerous syntax, whitespace and comment issues according to Michael's review. - Fix memory leaks. - Removed igb example device - a rebased version available on github instead.
