编译一个可以关机的内核
电源选项:<*> Advanced Power Management BIOS support
[*] Ignore USER SUSPEND
[*] Enable PM at boot time
[*] Make CPU Idle calls when idle
[ ] Enable console blanking using APM
[ ] RTC stores time in GMT
[ ] Allow interrupts during APM BIOS calls
[ ] Use real mode APM BIOS call to power off
尤其注意的是
[ ] MTRR (Memory Type Range Register) support
[ ] Symmetric multi-processing support
[ ] Local APIC support on uniprocessors
[ ] Unsynced TSC support
这一项[ ] Symmetric multi-processing support绝对不要选 why can not choose smp?
:-D
Re: 编译一个可以关机的内核
我是这样电源选项:
<*> Advanced Power Management BIOS support
[ ] Ignore USER SUSPEND
[*] Enable PM at boot time
[*] Make CPU Idle calls when idle
[*] Enable console blanking using APM
[ ] RTC stores time in GMT
[ ] Allow interrupts during APM BIOS calls
[ ] Use real mode APM BIOS call to power off
[*] MTRR (Memory Type Range Register) support (有助于性能提升,选上) 呵呵
这是我的
[*] Power Management support
[*] ACPI support
[ ] ACPI Debug Statements
<*> ACPI Bus Manager
<*> System
<M> Processor
<M> Button
< > AC Adapter
< > Embedded Controller
< > Advanced Power Management BIOS support mine, already can poweroff.

why can not choose smp?
在SMP的选项上按HELP不就知道啦 :mrgreen: ic, hehe, sorry, i never read that carefully. 可我真的有双cpu啊...... o, so for smp, u can not use pm now. hehe. 那个选项是管自动断电的?
我反而看不明白了…… 我的处理器不支持ACPI呀,图拉丁呀,居然不支持。
http://www.linuxfans.org/nuke/modules/Forums/files/APIC-2.JPG 往红框的右边看 靠!Linux 内核居然把 Symmetric multi-processing support默认为 Y !
我说怎么不能关机呢!
看来Linux是为服务器准备的…… :evil: 往红框的右边看,看到ACPI了吧。“MMX指令”上面
哪个图是以前问APIC问题的时候发的。懒得再贴图了,所以用的是那个老的图。
我想可能是桌面处理器都不支持吧,谁的支持ACPI?
