(Applies to kvm.git/master:25deed73) This is v5 of the series. For more details, please see the header to patch 2/2.
This series has been tested against the kvm-eventfd unit test, and appears to be functioning properly. You can download this test here: ftp://ftp.novell.com/dev/ghaskins/kvm-eventfd.tar.bz2 This series is ready to be considered for inclusion, pending any further review comments. [ Changelog: v5: *) Removed "cookie" field, which was a misunderstanding on my part on what Avi wanted for a data-match feature *) Added a new "trigger" data-match feature which I think is much closer to what we need. *) We retain the dev_count field in the io_bus infrastructure and instead back-fill the array on removal. *) Various minor cleanups *) Rebased to kvm.git/master:25deed73 v4: *) Fixed a bug in the original 2/4 where the PIT failure case would potentially leave the io_bus components registered. *) Condensed the v3 2/4 and 3/4 into one patch (2/2) since the patches became interdependent with the fix described above *) Rebased to kvm.git/master:74dfca0a v3: *) fixed patch 2/4 to handle error cases instead of BUG_ON *) implemented same HAVE_EVENTFD protection mechanism as irqfd to prevent compilation errors on unsupported arches *) completed testing *) rebased to kvm.git/master:7391a6d5 v2: *) added optional data-matching capability (via cookie field) *) changed name from iofd to iosignalfd *) added io_bus unregister function *) implemented deassign feature v1: *) original release (integrated into irqfd v7 series as "iofd") ] --- Gregory Haskins (2): kvm: add iosignalfd support kvm: make io_bus interface more robust arch/x86/kvm/i8254.c | 22 +++ arch/x86/kvm/i8259.c | 9 + arch/x86/kvm/x86.c | 1 include/linux/kvm.h | 15 ++ include/linux/kvm_host.h | 16 ++ virt/kvm/coalesced_mmio.c | 8 + virt/kvm/eventfd.c | 356 +++++++++++++++++++++++++++++++++++++++++++++ virt/kvm/ioapic.c | 9 + virt/kvm/kvm_main.c | 41 +++++ 9 files changed, 462 insertions(+), 15 deletions(-) -- Signature -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
