openbsd 4.0 怎么优化bsd.mp呢

怎么让openbsd 4.0支持 多 cup
我的cpu是2个 P4 2.8GHz 至强 超线程的,在win2k下显示有4个cpu的
使用bsd.mp内核可以显示2个cpu

怎么重新优化编译这个bsd.mp呢

最后是MP支持部分 /sys/arch/i386/conf/GENERIC.MP

include "arch/i386/conf/Genii" # 包含平台相关部分配置

option MULTIPROCESSOR # 多处理器支持

SMP support for multi-core, multi-CPU, and Hyper-Threaded machines
If you're on a multi-core or multi-CPU system and want to use the SMP kernel, you do not need to recompile anything to get SMP support. While OpenBSD uses the single-CPU kernel by default, you have the option of installing the bsd.mp kernel during the installation process. If you choose that option, bsd.mp will be in your / directory.

Before you switch to bsd.mp, test it out by typing it in at the boot prompt when the system starts (before OpenBSD starts its init process). If all goes well, just switch to your root directory and move bsd.mp to bsd:

mv bsd.mp bsd

是在内核里添加这句吗,我加了编译到中途有错误

option                MULTIPROCESSOR        # Multiple processor support

直接用 GENERIC.MP 内核配置文件。

另外，GENERIC.MP 文件里有一句 include，将另外一个基本的配置文件包含了进来。如果你需要调整内核，可以对这两个文件动手。

1soft

# cd /usr/src/sys/arch/i386/conf

dmassage -s GENERIC > 新文件1
cp GENERIC.MP 新文件2

vi 新文件2
include "arch/i386/conf/新文件1"

# config 新文件2
# cd ../compile/新文件2
# make clean && make depend && make
# make install
这样可以了,谢谢
