This message is in MIME format --_=XFMail.1.4.0.FreeBSD:011026043333:6073=_ Content-Type: text/plain; charset=us-ascii I was bored last night, so I cleaned up the powerpc trap() function. I don't have anything setup to test it, but I think it should compile and handle most kernel and user faults ok. (I haven't looked at the ALI faults yet, so they always fail right now.) (This is assuming the pmap code is done, it's just the necessary changes for trap() itself.) I also think that syscalls might work now, assuming that the NetBSD code this was cribbed from worked. Since my Note that some of the assembly stuff in locore.s still needs some work. Specifically, on return from interrupts and exceptions, we need to call the ast() function instead of doing an EXC_AST fake trap. I've got some comments to that effect in the patch. There are no guarantees that this compiles, but it should be a lot closer now to the final version. http://www.FreeBSD.org/~jhb/patches/ppc.patch -- John Baldwin <jhb@FreeBSD.org> --
