Patch 2 is stolen from Eric's series and is necessary for these\npatches to compile as well. Patch 3 includes the core support for\nmapped level-triggered interrupts. Patch 4 handles guest MMIO access to\nthe virtual distributor. Patch 5 moves some code around for patch 6.\nPatch 6 implements an optimization for the timer. The last two patches\ncould be deferred until the timer optimization series.\n\nBased on v4.13\n\nChanges since v2:\n - Removed patch 5 from v2 and integrating the changes in what's now\n patch 5 to make it easier to reuse code when adding VFIO integration.\n - Changed the virtual distributor MMIO handling to use the\n pending_latch and more closely match the semantics of SPENDR and\n CPENDR for both level and edge mapped interrupts.\n\nChanges since v1:\n - Added necessary changes to the timer (Patch 1)\n - Added handling of guest MMIO accesses to the virtual distributor\n (Patch 4)\n - Addressed Marc's comments from the initial RFC (mostly renames)\n\nThanks,\n-Christoffer\n\n---\n\nChristoffer Dall (4):\n KVM: arm/arm64: Don't cache the timer IRQ level\n KVM: arm/arm64: vgic: Support level-triggered mapped interrupts\n KVM: arm/arm64: Support VGIC dist pend/active changes for mapped IRQs\n KVM: arm/arm64: Provide a vgic interrupt line level sample function\n\nEric Auger (1):\n KVM: arm/arm64: vgic: restructure kvm_vgic_(un)map_phys_irq\n\n include/kvm/arm_vgic.h | 19 +++++++--\n virt/kvm/arm/arch_timer.c | 52 +++++++++++------------\n virt/kvm/arm/vgic/vgic-mmio.c | 33 +++++++++++++++\n virt/kvm/arm/vgic/vgic-v2.c | 29 +++++++++++++\n virt/kvm/arm/vgic/vgic-v3.c | 29 +++++++++++++\n virt/kvm/arm/vgic/vgic.c | 96 ++++++++++++++++++++++++++++++++++++-------\n virt/kvm/arm/vgic/vgic.h | 8 ++++\n 7 files changed, 219 insertions(+), 47 deletions(-)"}
