Our company uses FreeBSD on PowerPC e300 core and I wanted to compare our TLB
Data Store Miss Exception handler with the same part of code in NetBSD. In my
opinion there is a serious bug in sys/powerpc/powerpc/trap_subr.S file - lines
617-624. Value stored in R1 is not used. And changed value in R2 causes error
when reloading TLB entry. It would be great if I could contact someone who is
able to confirm (or not) my opinion.
I do not know - my FreeBSD kernel crashes.
I think it is not difficult but I am not sure at the moment.
