上次提到了无线网络,现在来说一下intel的双核处理器Core2 Duo/Solo在gentoo安装中的设置。要让Core 2 Duo/Solo处理器在gentoo里工作得正常需要从5个方面来设置。下面我一一来说明。相关阅读:Gentoo 安装之intel无线网卡篇 http://www.linuxidc.com/Linux/2012-03/56744.htmGentoo 安装之intel Core2 CPU篇 http://www.linuxidc.com/Linux/2012-03/56745.htmGentoo 安装之intel GMA显卡篇 http://www.linuxidc.com/Linux/2012-03/56745.htm
1.CflagsIntel Core 2 Duo/Quad / Xeon 51xx/53xx, Pentium Dual-Core T23xx+/Exxxx的硬件信息为:
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 CPU XXXX @ XXXGHz对于32bit的系统,安全的Cflags是这样的:
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"对于64bit的系统,安全的Cflags是这样的:
CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=nocona -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"2.内核设置对于所有的Core2系列CPU,你都应该激活下面的选项:
| Linux Kernel Configuration: |
Processor type and features---> Subarchitecture Type ()---> (X) PC-compatible Processor family ()---> (X) Pentium M [ ] Generic x86 support |
如果你的处理器是双核的,那么激活这个选项:
| Linux Kernel Configuration: |
Processor type and features---> [*] Symmetric multi-processing support (2) Maximum number of CPUs (2-256) [ ] SMT (Hyperthreading) scheduler support [*] Multi-core scheduler support |
如果你的系统是32bit的,那么激活这个选项:
| Linux Kernel Configuration: |
Processor type and features---> [*] Machine Check Exception < > Check for non-fatal errors on AMD Athlon/Duron / Intel Pentium 4 |
如果是64bit的,激活这个选项:
| Linux Kernel Configuration: |
Processor type and features---> -- Machine check support [*] Intel MCE features Executable file formats / Emulations---> [*] IA32 Emulation |
3.自动降频内核的配置
| Linux Kernel Configuration: CPU frequency scaling |
Power management options---> ACPI (Advanced Configuration and Power Interface) Support---> [*] ACPI Support <*> Processor CPU Frequency scaling---> [*] CPU Frequency scaling <*> CPU frequency translation statistics [*] CPU frequency translation statistics details |
省电方式(Governor)
它们决定了你的CPU运行的频率。最常用到的可能是"按需分配(ondemand)"和"保守(conservative)"了。你可以按照你的需要来进行调整。
- Conservative 将CPU设置为最省电的状态,当CPU需要使用更多电力的时候一步步地提升CPU的频率.
- Ondemand 将CPU的频率设置为最低,当CPU在最低频率时如果使用率达到100%把CPU的频率提升到额定频率。
- Powersave将CPU的频率一直设置为最低。
- Performance 使CPU保持额定频率运行。
- Userspace 允许你手动设置CPU的频率。
你可以随时改变你的CPU的省电方式。
| Linux Kernel Configuration: governor |
Power management options---> CPU Frequency scaling---> # E.g. for ondemand <*> "ondemand" cpufreq policy governor |
