Here is a summary of the changes I made or questions I have: * Patch 2: Fixed a few remaining changes that broke the build. Just remember that having the tree building after each commit helps a lot when one later needs to bisect. * Patch 4: when is the manager freed? </blockquote><div>It's hard to find a specified code point to free the manager, since we </div><div>don't know is there anyone else still using it. </div><div> </div> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> * Patch 5 & 6: remove the added ATTRIBUTE_UNUSED * Patch 9: added { } around if block to match else style. * Patch 10: remove added ATTRIBUTE_UNUSED * Patch 11: fixed indent function rename * Patch 42: Fix comment about qemuPrepareHostdevPCIDevices in earlier patch * Patch 47: remove added ATTRIBUTE_UNUSED * Patch 49: Fixed the version in libxl_driver.c as 1.2.2 is out The whole updated patch series is sitting here for those wanting to see the changes applied: <a href="https://github.com/cbosdo/libvirt/commits/hostdev-passthrough" target="_blank">https://github.com/cbosdo/libvirt/commits/hostdev-passthrough</a> Of course, I'ld love another pair of sharper eyes to look at the patch series. I'm not an expert on the hostdev topic ;) Kind regards -- Cedric <div class="HOEnZb"><div class="h5"> On Sat, 2014-03-01 at 14:28 +0800, Chunyan Liu wrote: > These patches implements a separate module for hostdev passthrough so that it > could be shared by different drivers and can maintain a global state of a host > device. > > Patches 1~6 are to switch existing qemu and lxc driver to use common library > lists, so that to maintain a global state of every host device. > > Patches 7~45 are to extract general code from qemu_hostdev.c piece by piece, > make them reusable common APIs. > > Patches 46: unit test for the virhostdev common library > Patches 47: add a hostdev backend type for xen > Patches 48: add pci passthrough to libxl driver based on the common library > Patches 49: change lxc to use common library APIs > > --- > changes to v12: > * split "add hostdev passthrough common library" patch into small patches > for easier review. > * fix v12 comments > * rebase to libxl changes > > > Chunyan Liu (49): > add 'driver' info to used_by > qemu: reuse hostdev interfaces to avoid duplicate > qemu: remove functions now used internally only from qemu_hostdev.h > add virhostdev files to maintain global state of host devices > qemu: use general virhostdev lists instead of its own > lxc: use general virhostdev lists instead of its own > qemu_hostdev: move cfg->relaxedACS as a flag > qemu_hostdev: move ColdBoot as a flag > qemu_hostdev: move netconfig file location to virhostdev stateDir > extract general code from qemuPrepareHostdevPCIDevices > rename qemu*NetConfigRestore/Replace to > virHostdevNetConfigRestore/Replace > rename qemuGet*PciHostDeviceList to virHostdevGet*PciHostDeviceList > pass driver name as a parameter to virHostdevPrepareHostdevPCIDevices > extract general code from qemuDomainReAttachHostdevDevices > pass driver name as a parameter to virHostdevReAttachPCIDevices > rename qemuReAttachPciDevice to virHostdevReAttachPciDevice > move virHostdevPrepare(ReAttach)PCIDevices to virhostdev.c > extract general code from qemuUpdateActivePciHostdevs > extract general code from qemuUpdateActiveUsbHostdevs > extract general code from qemuUpdateActiveScsiHostdevs > pass driver_name as parameter of virHostdevUpdate*Hostdevs functions > move virHostdevUpdate* functions to virhostdev.c > qemuPrepareUSBDevices: code adjustment for extracting general code > extract general code from qemuPrepareHostUSBDevices > rename qemu*USBDevices to virHostdev*USBDevices > pass driver name to virHostdevPrepareUSBDevices > move virHostdevPrepareHostUSBDevices to virhostdev.c > extract general code from qemuPrepareHostSCSIDevices > pass driver name as parameter to virHostdevPrepareSCSIDevices > move virHostdevPrepareHostSCSIDevices to virhostdev.c > extract general code from qemuDomainReAttachHostUsbDevices > pass driver name as paramter to virHostdevReAttachUsbHostdevs > move virHostdevDomainReAttachHostUsbDevices to virhostdev.c > extract general code from qemuDomainReAttachHostScsiDevices > pass driver name as parameter to virHostdevReAttachScciHostdevs > move virHostdevReAttachHostScsiDevices to virhostdev.c > extract general code of NodeDeviceDetach > extract general code of NodeDeviceReAttach > extract general code of NodeDeviceReset > move virHostdevNodeDevice* to virhostdev.c > improve parameter name to let it more meaningful > rename some function names to keep consistency > improve virHostdevUpdate* parameters to make it more widely used > add 3 wrapper functions for prepare/reattach/update domain hostdevs > add parameter checks to common interfaces > add unit test for new virhostdev common library > change lxc_hostdev.c to use virhostdev common library APIs > add hostdev pci backend type for xen > add pci passthrough to libxl driver > > .gitignore | 1 + > docs/schemas/domaincommon.rng | 1 + > po/POTFILES.in | 1 + > src/Makefile.am | 1 + > src/conf/domain_conf.c | 3 +- > src/conf/domain_conf.h | 1 + > src/libvirt_private.syms | 19 + > src/libxl/libxl_conf.c | 63 ++ > src/libxl/libxl_conf.h | 4 + > src/libxl/libxl_domain.c | 9 + > src/libxl/libxl_driver.c | 447 +++++++++++- > src/lxc/lxc_conf.h | 4 -
