I'm not a kernel tuning expert ;-)) |
| 31 |
However: |
| 32 |
|
| 33 |
a) my kernel config is: |
| 34 |
CONFIG_X86_64=y |
| 35 |
CONFIG_64BIT=y |
| 36 |
CONFIG_GENERIC_CPU=y |
| 37 |
CONFIG_X86_CPUID=y |
| 38 |
# CPU Frequency scaling |
| 39 |
CONFIG_CPU_FREQ=y |
| 40 |
CONFIG_CPU_FREQ_TABLE=y |
| 41 |
# CONFIG_CPU_FREQ_DEBUG is not set |
| 42 |
CONFIG_CPU_FREQ_STAT=y |
| 43 |
# CONFIG_CPU_FREQ_STAT_DETAILS is not set |
| 44 |
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y |
| 45 |
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set |
| 46 |
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y |
| 47 |
CONFIG_CPU_FREQ_GOV_POWERSAVE=y |
| 48 |
CONFIG_CPU_FREQ_GOV_USERSPACE=y |
| 49 |
# CONFIG_CPU_FREQ_GOV_ONDEMAND is not set |
| 50 |
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y |
| 51 |
# CPUFreq processor drivers |
| 52 |
CONFIG_X86_ACPI_CPUFREQ=y |
| 53 |
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set |
| 54 |
# CONFIG_CPU5_WDT is not set |
| 55 |

b) I do not use cpudyn, although recommended by the Gentoo Linux AMD64 |
