This series introduces support for in-kernel GICv3 ITS emulation. It is based on a kernel API which is not yet released.
Tested on Cavium ThunderX with virtio-net-pci and vhost-net. Kernel dependencies: - [PATCH v8 00/12] KVM: arm64: GICv3 ITS emulation http://www.spinics.net/lists/kvm/msg135048.html - [PATCH v6 0/6] KVM: arm/arm64: gsi routing support Those kernel series can be found at: https://github.com/eauger/linux/tree/v4.7-rc6-its-emul-v8-gsi-routing-v6 This QEMU series can be found at: https://github.com/eauger/qemu/tree/v2.6.0-vITS-v4 Previous version originally written by Pavel: - [RFC PATCH v3 0/5] vITS support https://lists.gnu.org/archive/html/qemu-devel/2015-11/msg05197.html History: v3 => v4: - Took into account Peter's comments (at the exception of sub-class operation changes, at the moment) - 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 "target-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 v1 => v2: - Added registers and reset method - Added unmigratable flag - Rebased on top of current master, use kvm_arch_fixup_msi_route() now Eric Auger (1): target-arm: move gicv3_class_name from machine to kvm_arm.h 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.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/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 | 16 --- 12 files changed, 505 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
