It is based on a kernel API which is not yet released. Tested on Cavium ThunderX with virtio-net-pci and vhost-net with both dt and ACPI guests Host Kernel dependencies: - [PATCH v10 00/17] KVM: arm64: GICv3 ITS emulation http://www.spinics.net/lists/kvm/msg135687.html - [RFC v9 0/6] KVM: arm/arm64: gsi routing support http://www.spinics.net/lists/kvm/msg136083.html Guest Kernel dependencies for resp. ACPI ITS and PCIe support: - [PATCH V7 0/8] Introduce ACPI world to ITS, https://lkml.org/lkml/2016/6/20/321 - Support for ARM64 ACPI based PCI host controller, https://lwn.net/Articles/690995/ Host kernel series can be found at: https://github.com/eauger/linux/tree/v4.7-its-emul-v10-gsi-routing-v9 This QEMU series can be found at: v5: https://github.com/eauger/qemu/tree/v2.6.0-vITS-v5 Previous versions are available at: v4: https://github.com/eauger/qemu/tree/v2.6.0-vITS-v4 v3: https://lists.gnu.org/archive/html/qemu-devel/2015-11/msg05197.html History: v4 => v5: - fix compilation issue with arm-softmmu target - rebase on target-arm: Fix unreachable code in gicv3_class_name() - add ACPI support - kernel ITS init sequence is not yet similar to GICv2/V3 ones. This will be addressed in a subsequent respin. v3 => v4: - Took into account Peter's comments (at the exception of sub-class operation changes) - rebase on Andre's kernel ITS emulation series v8 - rework KVM init sequence and KVM device creation/settings overall. I do not use kvm_arm_register_device due to the way the kernel API is devises (see discussion on the kernel ML) - change the computation of the GITS_TRANSLATER base address - fix compilation issues - new "arget-arm: move gicv3_class_name from machine to kvm_arm.h" v2 => v3: - Really added unmigratable flag, was overlooked in v2 - Fixed checkpatch issue with initializing static variable to zero /bin/bash: indent : commande introuvabledded registers and reset method - Added unmigratable flag - Rebased on top of current master, use kvm_arch_fixup_msi_route() now Pavel Fedin (5): hw/intc: Implement ITS base class kernel: Add vGICv3 ITS definitions kvm_arm: Pass requester ID to MSI routing functions kvm_arm: Implement support for ITS emulation by KVM arm/virt: Add ITS to the virt board Eric Auger (2): target-arm: move gicv3_class_name from machine to kvm_arm.h hw/arm/virt-acpi-build: Add ITS description in ACPI MADT table Pavel Fedin (5): hw/intc/arm_gicv3_its: Implement ITS base class linux-headers: update to 4.7-rc6 + ITS emulation and GSI routing target-arm/kvm: Pass requester ID to MSI routing functions hw/intc/arm_gicv3_its: Implement support for in-kernel ITS emulation arm/virt: Add ITS to the virt board hw/arm/virt-acpi-build.c | 7 + hw/arm/virt.c | 47 ++++++- hw/intc/Makefile.objs | 2 + hw/intc/arm_gicv3_its_common.c | 155 +++++++++++++++++++++ hw/intc/arm_gicv3_its_kvm.c | 145 +++++++++++++++++++ include/hw/acpi/acpi-defs.h | 13 +- include/hw/intc/arm_gicv3_its_common.h | 75 ++++++++++ include/standard-headers/linux/input-event-codes.h | 31 +++++ include/standard-headers/linux/input.h | 1 + linux-headers/asm-arm64/kvm.h | 2 + linux-headers/linux/kvm.h | 12 +- target-arm/kvm.c | 6 + target-arm/kvm_arm.h | 38 ++++- target-arm/machine.c | 15 -- 14 files changed, 524 insertions(+), 25 deletions(-) create mode 100644 hw/intc/arm_gicv3_its_common.c create mode 100644 hw/intc/arm_gicv3_its_kvm.c create mode 100644 include/hw/intc/arm_gicv3_its_common.h -- 2.5.5
