I think god explainig can be found in VMS Device Support Manual, Section 3 (for example http://odl.sysworks.biz/disk$cddoc04mar21/decw$book/d32va114.p63.decw$book#186). splXXX is analouge of VMS IPL 1-15 and have same purpose. Or The Design and Implementation of the 4.3BSD UNIX Operating System (Chapter 3.3). Also you can look in FreeBSD repo, stable/2.2 branch, sys/i386/include/spl.h _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
