supervisor data in data cache
i have been looking at leon3 implementation and i noticed there is no
supervisor bit in the cache tag (or a ACC bits like in the MMU entries.)
(sparc v8 manual does not talk about such a bit either)
and i was woundering if a user can read supervisor data from caches ?
did i missunderstand the code?
if i not mistaken a OS such as linux will run in supervisor mode?
i did see the CTX bits but mostly the OS is mapped to all the processes virtual memory...
