Where is CONFIG_PM_ADVANCED_DEBUG in the kernel [SOLVED]

[Budoka]

Powertop recommends...

Enable the CONFIG_PM_ADVANCED_DEBUG kernel configuration option.
This option will allow PowerTOP to collect runtime power management statistics.

I have searched the forums and found many references to the same thing but can't seem to find it in my kernel options, or in a thread stating where it lives.

Thanks.

Hello,

When you are in menuconfig you can search for modules, if you type '/'

Code: Select all

  ┌──────────────────────────────── Search Results ─────────────────────────────────┐
  │ Symbol: PM_ADVANCED_DEBUG [=n]                                                  │  
  │ Type  : boolean                                                                 │

Important is the

Depends on

-Option. Which says what you should have activate (and what not) to enable the option.

Also

Location

says where you have to browse to..

Is there an option in genkernel as well?

[Budoka]

OK. I figured out how to search on genkernel but am still having problems.

Genkernel indicates that CONFIG_PM_ADVANCED_DEBUG lives here:

Symbol: PM_ADVANCED_DEBUG [=y] │
│ Type : boolean │
│ Prompt: Extra PM attributes in sysfs for low-level debugging/testing │
│ Defined at kernel/power/Kconfig:159 │
│ Depends on: PM_DEBUG [=y] │
│ Location: │
│ -> Power management and ACPI options │
│ -> Power Management Debug Support (PM_DEBUG [=y])

However when I go to that directory it isn't. I only see:

[*] Suspend to RAM and standby │ │
│ │ [*] Hibernation (aka 'suspend to disk') │ │
│ │ () Default resume partition │ │
│ │ [ ] Opportunistic sleep │ │
│ │ [ ] User space wakeup sources interface │ │
│ │ [*] Run-time PM core functionality │ │
│ │ [*] Power Management Debug Support │ │
│ │ [*] Extra PM attributes in sysfs for low-level debugging/testing │ │
│ │ [ ] Suspend/resume event tracing │ │
│ │ [*] ACPI (Advanced Configuration and Power Interface) Support ---> │ │
│ │ [ ] SFI (Simple Firmware Interface) Support ---> │ │
│ │ CPU Frequency scaling ---> │ │
│ │ -*- CPU idle PM support │ │
│ │ [ ] Cpuidle Driver for Intel Processors │ │
│ │ Memory power savings ---> │ │
│ │

There isn't any sub-menu for Power Management Debug Support . Any ideas?

[Budoka]

OK. I found it. Some of the menu items changed.
