Struct Sscratch

pub struct Sscratch(pub VAddr);

Expand description

A dedicated register for the supervisor to hold whatever data it would like to. Generally used to hold a pointer to a hart-local supervisor context - it can be swapped with a user register at the beginning of a trap handler to provide an initial working register.
