Hello,
I am trying to set a watch exception in (IDT RC32334) my debugging
execise
In arch/mips/lib/watch.S says "curremtly available only for KSEG0
address"
which is evident by following assembly..
LEAF(__watch_set)
li t0,0x80000000
subu a0,t0
ori a0,7
xori a0,7
or a0,a1
mtc0 a0,CP0_WATCHLO
.......
it is loading the physical address of KSEG0 addresses in CP0
watchpoint register.
in change history of this file i am able to see KSEG0 restriction
removed only for arch/mips64/lib/watch.S...
while my manual is not specific about KSEG0 , can i safely use it
for all addresses ,offcourse then above assembly has to be
modified appropiately for addresses of different regions..
Best Regards.
Ashish
