I really like cpufreqd because I can monitor the temperature of my system and the programs that are running (like folding at home)
I added the command in the local.start script 
I hope that helps |
crashed again.
after checking the message, it shows
Mar 25 21:36:31 PD cpufreqd: acpi_battery_init : Couldn't open BAT attributes
Mar 25 21:36:31 PD cpufreqd: get_class_device_attribute: couldn't open /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT/current_now (No such file or directory)
it seems that there is a problem with the workings of acpi on my laptop.
There are always acpi issues on my laptop, not only with that but also with my fan working.... |
Hello!
I've had the same problem.
Try to check if file /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT/power_now exists
If yes, then you should to recompile cpufreqd with some changes in source code:
file cpufreqd-2.4.2/src/cpufreqd_acpi_battery.c
line 38
Change from #define CURRENT_NOW "current_now" to #define CURRENT_NOW "power_now"

PPS: It helps me. |

This file does exist. But I don't know where the C file is. Could you tell me please? Thanks |

The easiest, but wrong way:
%> sudo emerge -1v cpufreqd
| Code: | * cpufreqd-2.4.2.tar.bz2 RMD160 SHA1 SHA256 size ;-) ... [ ok ]
>>> Unpacking source...
>>> Unpacking cpufreqd-2.4.2.tar.bz2 to /var/tmp/portage/sys-power/cpufreqd-2.4.2-r1/work
>>> Source unpacked in /var/tmp/portage/sys-power/cpufreqd-2.4.2-r1/work
>>> Preparing source in /var/tmp/portage/sys-power/cpufreqd-2.4.2-r1/work/cpufreqd-2.4.2 ...
* Applying cpufreqd-conf.d.patch ... [ ok ]
* Applying cpufreqd-2.4.2-PATH_MAX.patch ... [ ok ]
>>> Source prepared.
>>> Configuring source in /var/tmp/portage/sys-power/cpufreqd-2.4.2-r1/work/cpufreqd-2.4.2 ... |
At this time you should press Ctrl-Z.
| Code: | [1]+ Stopped emerge -1v cpufreqd
%>
|
In the other win open and edit file /var/tmp/portage/sys-power/cpufreqd-2.4.2-r1/work/cpufreqd-2.4.2/src/cpufreqd_acpi_battery.c
Then go back and enter fg command, so emerging will continue.
This will work, BUT this is wrong way, because after next full system upgrade these changes will be lost.
The right way:
1. create patch
2. put your own copy cpufreqd ebuild with patch to local overlay
3. submit patch to bugtracker
