This was also the opportunity to try to fix the issue laterly reported by Zenghui, related to the RDIST_TYPER last bit emulation. The final patch is a first batch of VGIC init sequence selftests. Of course they can be augmented with a lot more register access tests, but let's try to move forward incrementally ... Best Regards Eric This series can be found at: https://github.com/eauger/linux/tree/vgic_kvmselftests_v4 History: v3 -> v4: - take into account Drew's comment on the kvm selftests. No change to the KVM related patches compared to v3 v2 ->v3: - reworked last bit read accessor to handle contiguous redist regions and rdist not registered in ascending order - removed [PATCH 5/9] KVM: arm: move has_run_once after the map_resources v1 -> v2: - Took into account all comments from Marc and Alexandru's except the has_run_once still after the map_resources (this would oblige me to revisit in depth the selftests) Eric Auger (8): KVM: arm64: vgic-v3: Fix some error codes when setting RDIST base KVM: arm64: Fix KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION read KVM: arm64: vgic-v3: Fix error handling in vgic_v3_set_redist_base() KVM: arm/arm64: vgic: Reset base address on kvm_vgic_dist_destroy() docs: kvm: devices/arm-vgic-v3: enhance KVM_DEV_ARM_VGIC_CTRL_INIT doc KVM: arm64: Simplify argument passing to vgic_uaccess_[read|write] KVM: arm64: vgic-v3: Expose GICR_TYPER.Last for userspace KVM: selftests: aarch64/vgic-v3 init sequence tests .../virt/kvm/devices/arm-vgic-v3.rst | 2 +- arch/arm64/kvm/vgic/vgic-init.c | 13 +- arch/arm64/kvm/vgic/vgic-kvm-device.c | 3 + arch/arm64/kvm/vgic/vgic-mmio-v3.c | 116 +++- arch/arm64/kvm/vgic/vgic-mmio.c | 10 +- arch/arm64/kvm/vgic/vgic.h | 1 + include/kvm/arm_vgic.h | 3 + tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 1 + .../testing/selftests/kvm/aarch64/vgic_init.c | 652 ++++++++++++++++++ .../testing/selftests/kvm/include/kvm_util.h | 9 + tools/testing/selftests/kvm/lib/kvm_util.c | 77 +++ 12 files changed, 838 insertions(+), 50 deletions(-) create mode 100644 tools/testing/selftests/kvm/aarch64/vgic_init.c -- 2.26.3 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
