cva6是一颗具备6级流水、单发射、顺序执行的64bit RISC-VCPU,不仅实现了RV64IMAFDC(RV64GC)指令,也实现了RISC-V三种特权等级,因此具备运行类Unix系统的能力。 Image 注:目前官方的图没有更新到最新的主线,有细微的差别。 cva6特性概览 RV64GC 实现了RV64IMAFDC,即支持整数指令I、整数乘除M、单精度浮点F、...
打开<cva6-sdk Dir>/u-boot/arch/riscv/dts/cv64a6_genesysII.dts,修改isa / { ... cpus { ... CPU0: cpu@0 { ... riscv,isa = "rv64imafdch"; # add h here ... 在完成修改之后,重新生成镜像,写入SD卡,运行,发现此时系统已支持KVM 可通过以下命令查看是否支持KVM,结果如图所示 ls /dev...
CVA6 is a 6-stage, single-issue, in-order CPU which implements the 64-bit RISC-V instruction set. It fully implements I, M, A and C extensions as specified in Volume I: User-Level ISA V 2.3 as well as the draft privilege extension 1.10. It implements three privilege levels M, S, ...

The CORE-V CVA6 is an Application class 6-stage RISC-V CPU capable of booting Linux - ranaadeel-10x/cva6
首先排除自身CPU以及CPU的OEM厂商对虚拟化的限制 剩下的就涉及到一个新的概念:arm64异常级别(Exception Level 简称为EL) 这里的异常指的是 在精简指令集(RISC)体系结构中 中断或打断程序正常执行的事件 //不理解没关系 arm64有4个异常级别EL0/1/2/3 ...
