A sysctl-controlled variable would be nice although I don"t see why anyone would want to run without this feature :-) Has anyone tried to use the MMX registers to "emulate" the FPU-based bcopy/bzero/copyin/out routines ? The K6 is said to be a fast MMX processor... I have no documentation on both the assembler syntax (well, maybe somewhere deeply buried) and the MMX registers so it is difficult for me to try it. -- Ollivier ROBERT -=- FreeBSD: There are no limits -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 3.0-CURRENT #10: Fri May 23 22:47:39 CEST 1997
