Just updated trap.patch. It prints out the cpuid, the kernel stack pointer, and for non-kthreads the user stack pointer now. On a somewhat related note, 64-bit kernel addresses really screw up the output of things like 'ps'. Would there be any large objection to dropping the first 5 'f's, the first three '0's from kernel pointers in ps output? Thus, instead of: fffffe000915e9c0 fffffc0000790000 you would get: e915e9c0 c0790000 etc. Granted, this is somewhat cryptic, but it would make ps work halfway decent. :-P >> Drew -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
