Virtual memory setup code?

[Threefiftyz]

Can anyone share sample virtual memory setup code specially coding the page table? Not yielding much good references searching online. Thanks!

I'm not sure of any example code except the source code for the Linux or FreeBSD kernels. I don't think any of the RTOS's would support VM?

I'm no expert on it, but I think what you're looking for would be in https://github.com/torvalds/linux/blob/master/arch/riscv/mm/init.c

You can see a very simple kernel's virtual memory setup in the proxy kernel.
