I re-used an old email when composing this. :) Marcello, Avi, and myself have previously agreed that Marcello's mmio-locking cleanup should go in first. When that happens, I will need to rebase this series because it changes how you interface to the io_bus code. I should have mentioned that here, but forgot. (Speaking of, is there an ETA when that code will be merged Avi?) That aside, after I sent this series I went to get some coffee to clear my head and I thought of an issue in the code. I will reply inline to patch 2/2. -Greg > [ > 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(-) > >
