如何在 Linux 上为 AMD A6 6310 启用 AMD Turbo Core？

我使用 Lubuntu 15.04，我注意到我的处理器（AMD A6 6310）以 1800 MHz 频率工作，不会更高，而 AMD 承诺通过 Turbo Core 选项可达 2.4 GHz。

如何启用 Turbo Core 选项？

$ cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4.0 us.
hardware limits: 1000 MHz - 1.80 GHz
available frequency steps: 1.80 GHz, 1.60 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1000 MHz and 1.80 GHz.
              The governor "ondemand" may decide which speed to use
              within this range.
current CPU frequency is 1000 MHz.
cpufreq stats: 1.80 GHz:36,16%, 1.60 GHz:2,73%, 1.40 GHz:3,99%, 1.20 GHz:11,66%, 1000 MHz:45,45%  (14681)

Supported: yes
Active: yes

Turbo Core 是否可用取决于您的 GPU 驱动程序（radeon、fglrx）。但即使 Turbo Core 可用，您也不会看到任何提示，除非您执行modprobe msr。
