• MSGBOX_IRQ:Msgbox中断; • RPMsg:基于VirtIO管理的共享内存所实现一套少量数据传输的框架; • RPbuf:全志基于RPMsg所实现一套大量数据传输的框架。 由上图可知(以RISC-V核向A核发送数据为例),RPbuf首先将数据放置在DDR中,再将缓冲区首地址和大小通过RPMsg发送至A核(RPMsg将缓冲区首地址和大小放入VRING,...

To simplify software support, the platform uses virtio devices for disks, networking, and entropy (instead of devices from some specific real-world RISC-V-based system-on-chip (SoC)). For all practical purposes, it looks and feels like a small embedded system, even though it ...
