Bug ID: 218919
Summary: My machine enter automaticaly in ondemand but my
kernel config have default CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE enable by default
Product: Power Management
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: cpufreq
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Hi Kernel Team,
I notice this today:
```
analyzing CPU 6:
driver: intel_cpufreq
CPUs which run at the same hardware frequency: 6
CPUs which need to have their frequency coordinated by software: 6
maximum transition latency: 20.0 us.
hardware limits: 800 MHz - 5.00 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave,
performance, schedutil
current policy: frequency should be within 800 MHz and 5.00 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
```Ondemand is enabled on boot, but in my kernel config i have CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE at default option.
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
I think is not correctly this.
Reproduce:
1. intel_pstate=passive
2. intel_pstate=disable
2. intel_pstate=no_hwp
4. acpi_cpufreq
I not have installed userspace controller for scheduler.
