Hi Paolo and Radim, Here is the second pull request for KVM/ARM for v4.15. These changes introduce GICv4 support in KVM/ARM, allowing direct injection of LPIs from devices generating MSIs into VMs. The changes rely on irqchip infrastructure for GICv4 already merged in tip:irq/core.
The pull request is based on kvm-arm-for-v4.15 plus 722c908f84c6 merged from tip:irq/core. The diffstat has been trimmed to only show the changes between the merge base mentioned above and the KVM/ARM side of GICv4 support, and does not include the additional changes in KVM not present in tip:irq/core. I expect that pulling this into the KVM tree after the irq/core changes land in Linus' tree should result in a clean subsequent pull request upstream, but let me know if you want me to work this out in some other way. The following changes since commit 722c908f84c67bf120105ca870675cadc1bb7b20: Merge tag 'irqchip-4.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core (2017-11-02 19:18:08 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvm-arm-gicv4-for-v4.15 for you to fetch changes up to 95b110ab9a093b5baf3a72e51f71279368d618e2: KVM: arm/arm64: Don't queue VLPIs on INV/INVALL (2017-11-10 09:59:20 +0100) Thanks, -Christoffer Christoffer Dall (2): KVM: arm/arm64: Fix GICv4 ITS initialization issues KVM: arm/arm64: Don't queue VLPIs on INV/INVALL Eric Auger (2): KVM: arm/arm64: register irq bypass consumer on ARM/ARM64 KVM: arm/arm64: vgic: restructure kvm_vgic_(un)map_phys_irq Marc Zyngier (23): KVM: arm: Select ARM_GIC_V3 and ARM_GIC_V3_ITS KVM: arm/arm64: vgic: Move kvm_vgic_destroy call around KVM: arm/arm64: vITS: Add MSI translation helpers KVM: arm/arm64: vITS: Add a helper to update the affinity of an LPI KVM: arm/arm64: GICv4: Add property field and per-VM predicate KVM: arm/arm64: GICv4: Add init/teardown of the per-VM vPE irq domain KVM: arm/arm64: GICv4: Wire mapping/unmapping of VLPIs in VFIO irq bypass KVM: arm/arm64: GICv4: Handle INT command applied to a VLPI KVM: arm/arm64: GICv4: Unmap VLPI when freeing an LPI KVM: arm/arm64: GICv4: Propagate affinity changes to the physical ITS KVM: arm/arm64: GICv4: Handle CLEAR applied to a VLPI KVM: arm/arm64: GICv4: Handle MOVALL applied to a vPE KVM: arm/arm64: GICv4: Propagate property updates to VLPIs KVM: arm/arm64: GICv4: Handle INVALL applied to a vPE KVM: arm/arm64: GICv4: Use pending_last as a scheduling hint KVM: arm/arm64: GICv4: Add doorbell interrupt handling KVM: arm/arm64: GICv4: Use the doorbell interrupt as an unblocking source KVM: arm/arm64: GICv4: Hook vPE scheduling into vgic flush/sync KVM: arm/arm64: GICv4: Enable virtual cpuif if VLPIs can be delivered KVM: arm/arm64: GICv4: Prevent a VM using GICv4 from being saved KVM: arm/arm64: GICv4: Prevent userspace from changing doorbell affinity KVM: arm/arm64: GICv4: Enable VLPI support KVM: arm/arm64: GICv4: Theory of operations Documentation/admin-guide/kernel-parameters.txt | 4 + Documentation/virtual/kvm/devices/arm-vgic-its.txt | 2 + arch/arm/kvm/Kconfig | 5 + arch/arm/kvm/Makefile | 1 + arch/arm64/kvm/Kconfig | 3 + arch/arm64/kvm/Makefile | 1 + include/kvm/arm_vgic.h | 41 ++- virt/kvm/arm/arch_timer.c | 24 +- virt/kvm/arm/arm.c | 48 ++- virt/kvm/arm/hyp/vgic-v3-sr.c | 9 +- virt/kvm/arm/vgic/vgic-init.c | 7 + virt/kvm/arm/vgic/vgic-its.c | 204 ++++++++---- virt/kvm/arm/vgic/vgic-mmio-v3.c | 5 + virt/kvm/arm/vgic/vgic-v3.c | 14 + virt/kvm/arm/vgic/vgic-v4.c | 364 +++++++++++++++++++++ virt/kvm/arm/vgic/vgic.c | 67 +++- virt/kvm/arm/vgic/vgic.h | 10 + 17 files changed, 695 insertions(+), 114 deletions(-) create mode 100644 virt/kvm/arm/vgic/vgic-v4.c -- 2.14.2 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
