cpu 补丁 linux,【原创】Linux下的cpu降压内核补丁——phc
1、选择补丁类型
在,我们可以下载phc的补丁代码,根据你内核选择cpufreq processor驱动的不同,分别有3个不同驱动的补丁
patches for acpi-cpufreq
patches for speedstep-centrino
patches for powernow-k8
先看看这些不同的cpufreq驱动在内核中的描述
CONFIG_X86_ACPI_CPUFREQ:
│ │
│ This driver adds a CPUFreq driver which utilizes the ACPI │
│ Processor Performance States. │
│ This driver also supports Intel Enhanced Speedstep.
支持ESS,可以用于pentium M、Core和Core2的cpu。
CONFIG_X86_POWERNOW_K8: │
│ │
│ This adds the CPUFreq driver for mobile AMD Opteron/Athlon64 processors │
│ │
│ To compile this driver as a module, choose M here: the │
│ module will be called powernow-k8.
AMD的,不太熟悉,不过已经列出cpu型号了,mobile AMD Opteron/Athlon64。
CONFIG_X86_SPEEDSTEP_CENTRINO: │
│ │
│ This is deprecated and this functionality is now merged into │
│ acpi_cpufreq (X86_ACPI_CPUFREQ). Use that driver instead of │
│ speedstep_centrino. │
│ This adds the CPUFreq driver for Enhanced SpeedStep enabled │
│ mobile CPUs. This means Intel Pentium M (Centrino) CPUs │
│ or 64bit enabled Intel Xeons.
也是支持ESS cpu的驱动,不过描述里面已经建议用acpi_cpufreq (X86_ACPI_CPUFREQ)了。
所以不难选择,intel选acpi-cpufreq,amd选powernow-k8。
