当前存在的一系列问题（250421）：

  • RISC-V 的中断注入代码未检查合并。
  • x86 下时钟时间不准确（似乎不是中断注入的问题）。
  • aarch64 下，由于未正确提供 CNTFRQ_EL0 虚拟化，导致时钟出现问题。目前Workaround：修改axconfig.toml，使得arceos的tickrate等于硬件的 CNTFRQ_EL0。
  • aarch64 下，没有对注入中断到等待中的 VCpu 做处理，仅能注入到当前运行的 VCpu。
  • aarch64 下，中断注入依赖硬件功能，目前暂时通过 arm_vcpu ➡️ axvisor_api ➡️ axhal 的流程调用，使代码符合预期结构，然后中间两段接口如何做到架构统一仍然需要思考。
  • PerCpu 中断控制器是作为 device 收拢到 axvm 这一层被管理，还是直接嵌入到 VCpu 中，需要统一做法。
