Powertop recommends...

Quote:
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:
  ┌──────────────────────────────── Search Results ─────────────────────────────────┐
  │ Symbol: PM_ADVANCED_DEBUG [=n]                                                  │ 
  │ 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                                        │ 
  │ (1)   -> Power Management Debug Support (PM_DEBUG [=y])

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

Genkernel indicates that CONFIG_PM_ADVANCED_DEBUG lives here:

Quote:
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:

Quote:
[*] 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?

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