FreeBSD支持SMP否????
原帖由 "hdcola" 发表:
我的是HT的CPU,操作系统是4.9,把HTT的#去了,config时说没有HTT,只去SMP和APIC_IO它就直接认出二个cpu了。
真是很奇怪的说。
4.9 的 HTT 已经变成默认的了,所以就没有该选项了:

FreeBSD 4.9-RELEASE.
20031022:
Support for HyperThread logical CPUs has now been enabled by
default. As a result, the HTT kernel option no longer exists.
Instead, the logical CPUs are always started so that they can
handle interrupts. However, the extra logical CPUs are prevented
from executing user processes by default. To enable the logical
CPUs, change the value of the machdep.hlt_logical_cpus from 1 to
0. This value can also be set from the loader as a tunable of
the same name.
