From: Vijaya Kumar K <[email protected]> This patchset adds API for saving and restoring of VGICv3 registers to support live migration with new vgic feature. This API definition is as per draft version of VGICv3 specification https://lists.cs.columbia.edu/pipermail/kvmarm/2016-May/020355.html
To test live migration with QEMU, the QEMU patches will be posted soon. The patch 3 & 4 are picked from the Pavel's previous implementation. http://www.spinics.net/lists/kvm/msg122040.html Vijaya Kumar K (4): arm/arm64: vgic-new: Introduce 64-bit reg access support arm/arm64: vgic-new: Add distributor and redistributor access arm/arm64: vgic-new: Introduce find_reg_by_id() arm/arm64: vgic-new: Implement VGICv3 CPU interface access arch/arm64/include/uapi/asm/kvm.h | 12 ++ arch/arm64/kvm/Makefile | 1 + arch/arm64/kvm/sys_regs.c | 22 ++-- arch/arm64/kvm/sys_regs.h | 4 + include/linux/irqchip/arm-gic-v3.h | 4 + virt/kvm/arm/vgic/vgic-kvm-device.c | 120 +++++++++++++++++-- virt/kvm/arm/vgic/vgic-mmio-v2.c | 4 +- virt/kvm/arm/vgic/vgic-mmio-v3.c | 111 +++++++++++++++++ virt/kvm/arm/vgic/vgic-mmio.c | 2 +- virt/kvm/arm/vgic/vgic-sys-reg-v3.c | 225 +++++++++++++++++++++++++++++++++++ virt/kvm/arm/vgic/vgic.h | 14 +++ 11 files changed, 497 insertions(+), 22 deletions(-) create mode 100644 virt/kvm/arm/vgic/vgic-sys-reg-v3.c -- 1.7.9.5 _______________________________________________ kvmarm mailing list [email protected] https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
