Cacheability in virtualized environment and cache control bits

[jc riscvproject]

Hi,

I have 2 questions similar to this question from a few days ago regarding cacheability and cache control.

From the privileged spec I see that virtualization can be enabled or disabled depending on the MODE field in the satp CSR.

Is there a similar way to disable the cache?

Also, in virtual mode or in a virtualized environment such as linux, is there an optimal or standard way to keep track of the cacheability of physical memory locations?

Thanks
