 Posted: Tue Apr 14, 2015 4:00 am Post subject: [SOLVED] Acpitool does not return thermal information |
 |
|
I am trying to retrieve my CPU thermal information with acpitool although it is showing up as not available.
I used strace on the acpitool application and it turns out it is trying to access "/proc/acpi/thermal_zone/" which does not exist, so in attempts to remedy this I enabled more of the ACPI depreciated file structures in the kernel config and recompiled my kernel, only to have two more directories added to "/proc/acpi/" none of which are thermal_zone.
I am running the 3.2.65 kernel on a HP envy 4 1130us laptop. I have tried to enable quite a few of the depreciated ACPI options in the kernel, but I either haven't found the right one, or this kernel does not support it.
Here are my ACPI kernel options that I have enabled.
| Code: | ~ # cat /usr/src/linux/.config | grep ACPI
CONFIG_X86_64_ACPI_NUMA=y
CONFIG_ACPI=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_PROCFS=y
CONFIG_ACPI_PROCFS_POWER=y
CONFIG_ACPI_PROC_EVENT=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_VIDEO=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_DOCK=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_HOTPLUG_CPU=y
CONFIG_ACPI_THERMAL=y
CONFIG_ACPI_NUMA=y
CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_X86_ACPI_CPUFREQ=y
CONFIG_PNPACPI=y
CONFIG_ATA_ACPI=y |
If acpitool is no longer a viable way to obtain this information is there another tool out there to retrieve this information from /sys/ instead where the information now resides?
Thanks all!

Decided to re-disable the features and roll my own bash script that I run as root to solve the problem.
| Code: | bat_status=`sudo cat /sys/class/power_supply/BAT1/status` ;
bat_charge_now=`sudo cat /sys/class/power_supply/BAT1/charge_now` ;
bat_charge_full=`sudo cat /sys/class/power_supply/BAT1/charge_full` ;
bat_charge_percent=`echo "$bat_charge_now / $bat_charge_full * 100" | bc -l` ;
system_temp=`sudo cat /sys/class/thermal/thermal_zone0/temp` ;
system_temp_c=`echo "$system_temp / 1000" | bc -l` ;
echo "Battery: ${bat_status} (${bat_charge_percent%.*}%), Temp: ${system_temp_c%.*}C" ; |
Wonder why no one has patched acpitool to look in the right directories yet. |
