shorter syntax on privilege export 2023-01-16 12:39:55 +01:00
buncram 2297f8aea0 also need to expose privilege state
turns out SATP is not enough to figure out what code you're running,
because the kernel code is mapped into all userspace's virtual memory
areas. You also need the privilege state to be exported.

This creates an option to export those bits.

Expand SATP register to 22 bits per spec

bunnie bf3521f86a Expand SATP register to 22 bits per spec
Vex only implements a 32-bit PA which does not take advantage
of the potetnial 32-bit space in Sv32 mode. Very reasonably,
Vex simply discards the top two unused bits.

However, the spec does require that the register occupy all 22
bits and it is possible for the OS to use the extra bits up top
for some bookkeeping purpose. This commit proposes to expand the
register to occupy the full 22 bits in case an OS is written
to utilize the full width of the register as written in the spec.
