面向混合关键度软件定义汽车的 Type-1 裸金属虚拟化架构
在单颗 SoC 上将安全仪表盘、ADAS 辅助驾驶与安卓娱乐大屏融合,必须具备形式化可证明的“免于干扰”(FFI)。Type-1 裸金属虚拟化通过硬件级物理核绑定与内存页锁死确保各子系统独立运转。
Type-1 Hypervisor Zonal Architecture
Central Controller: Type-1 Hypervisor — Mixed Criticality
Zonal Control Units & TSN Ring
- ASIL-D RTOS VM
- Android IVI VM
- Virtio-GPU Driver
- Arm SMMU Guard
- Core Pinning Pool
在多操作系统共存的车载计算环境中实现绝对的“免于干扰(FFI)”
当安卓座舱系统突发大量显存请求或偶发内核崩溃死机时,车辆底层的 ASIL-D 级安全仪表盘绝对不允许发生任何掉帧或响应卡顿。Type-1 裸金属虚拟化底层直接借助 Arm Stage-2 硬件页表与 SMMU 内存管理单元,在芯片物理层阻断跨虚拟机的一切非法干扰。
