Bug 352019 – sys-power/phctool cannot find /proc/acpi/processor/CPU./info

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Fabio Veronese 2011-01-18 13:21:02 UTC]

Phctool python-based graphic interface seems to not work due to the way CPUs id is defined. Looks like it's based still on /proc/acpi/processor/CPU./info which is not present in my system. It looks like that kernel 2.6.36 and later doesn't support those deprecated /proc/acpi directories even with CONFIG_ACPI_PROCFS enabled. 

Reproducible: Always

Steps to Reproduce:
1. Run phctool from terminal or open the dialogue window from the trayicon
Actual Results:  
No window opens, if run in terminal you get:


Traceback (most recent call last):
  File "./phctool.py", line 468, in <module>
    app=appgui()
  File "./phctool.py", line 81, in __init__
    self.cpuinfo=cpuinfo.cpuinfo()				##functions to gather CPU informations
  File "inc/libs/cpuinfo.py", line 12, in __init__
    self._get_acpi_cpus()		##get ACPI-supported CPUs
  File "inc/libs/cpuinfo.py", line 43, in _get_acpi_cpus
    self.data[cpunr]['acpi']['exist']=False
UnboundLocalError: local variable 'cpunr' referenced before assignment


Expected Results:  
Open UI GUI. Looks like that functionality is still available, just the GUI is missing.

A new corrected version of the bugged file

New version of the bugged file. The functionality has been restored, though some small differences in code behaviour. Full working in my system

[Comment 2 Michael Weber (RETIRED) 2011-01-22 16:13:59 UTC]

Is this patch compartible with the older (<2.6.36) kernels?

It was, but better move to this other version which I tested on both 2.6.36.r5 and 2.6.35.r15. Changes:
   - Fallback on old script
   - Relies on online CPU, no more on present (but maybe inactive) CPU.

Fixed and added fallback on old script

(This is the entire file, not actually a patch)
