Free acpi software for linux

Yacpi is an acpi monitoring program for Linux. yacpi displays various acpi information like battery status and ac status on notebooks.

WMAcpi is port of WMApm 1.1 with ACPI support.

Implementation of "ACPI" mode:

As far as I know, there arent any tools available right now to process battery statistics provided in /proc/power by ACPI stuff in 2.4.x kernels. So, I updated wmapm 1.1 to handle ACPI also. There are no changes between 1.1 and 1.2 other than ACPI stuff. If you are NOT interested in ACPI, this version is NOT for you. However, if you ARE interested in ACPI, please test this and
let me know if it works for you. This code makes a couple assumptions, they
are as follows:

* You only have one battery, and its a "Control Method" battery
* Your ACPI bios is more or less "not fucked up" (i.e. it works with 2.4.2)
* VERY IMPORTANT: You are running kernel 2.4.2. This has been tested under 2.4.2 kernel ONLY, and is not guaranteed to work with anything else. You have been warned.

To use ACPI support, just follow "INSTALL" instructions. Makefile has been updated to include -DACPI. If you dont have ACPI, you dont need this version of wmapm. Information after "INSTALL" section only applies to APM systems, without ACPI support.

Installation:

* make
* copy wmapm somewhere useful
* dance
* < somewhere useful >/wmapm &
* phear
(if it doesnt work, skip the phear step)

Note, this (for now) only supports laptops with one system battery. I am working with kernel acpi people to standartize power reporting interface, and when its usable, WMApm will be updated to support any number of batteries, and provide full information about ACPI power sources.

acpitail project shows in a tail-like way information off the battery-state, fan-states, temperatures, etc. of an ACPI capable system (mostly laptops).

wmacpi_temp is a Window Maker dock application that reads the temperature file in /proc/acpi in ACPI enabled kernels. In short, it displays the temperature of the processor, updated every minute (in Celsius or Fahrenheit).

Installation:

1. make
2. su
3. make install (to put it in /usr/local/bin)
or
make install-x11 (to put it in /usr/X11R6/bin)
5. exit

wmacpiload is a dockapp for monitoring CPU temp and battery time from ACPI. In the style of wmcpuload and wmapmload.

I can make no guarantee about this codes functionality on systems other than Linux - I do not have other OSes to test upon (least ways ones that I regularly boot into).

Also keep in mind that some systems dont support suspend etc in ACPI - as usual the risk is yours. Thats about all I can offer in the way of advice - feel free to email me with suggestions etc.

WMApm is your typical laptop APM (Advanced Power Management) dockapp. One interesting feature is "timer" mode, where you can keep track of how long the laptop has been "on battery". This is opposite of the information usually provided by the BIOS, which is "time remaining", and in many cases wrong. This option can be toggled at run-time.

System messages scroll on the bottom of the window, AC plug flashes when battery is charging, and green LED inside the big button flashes red if battery level is critical low. Since version 1.1 there are some #defines for broken APM BIOSes to disable certain features.

Installation:

* make
* copy wmapm somewhere useful
* dance
* /wmapm &
* phear
(if it doesnt work, skip the phear step)

This works on all machines that have a standard non-borked APM implementation. For people with broken APM implementations, I added some stuff, which was sent to me by Daniel Pittman, to compensate for some of the stupidity. If you see dumb behaviour from wmapm, consider editing wmapm.c and uncomment one, or both, of these lines (on lines 19 and 20):

#define RETARDED_APM if your bios thinks the battery is charging all the time when its on AC power. What this will do is stop "charging" process as soon as the battery reaches 100%.

#define STUPID_APM if your bios shows -1 minutes remaining when AC is plugged in, or when battery is charging.

If your bios is even dumber than this, and you come up with another special case that needs to be handled, feel free to #ifdef it under < badword >_APM and send me a diff -u. I will include it in the next version. Any of these changes would have to go into acquire_apm_info. Note, I changed format of apminfo structure to get rid of redundancy - now there is only one power state variable, which keeps track whether we are on AC, charging, battery, etc.

Note, all the *_APM stuff is untested - my laptop has a working BIOS. If you test this and it doesnt work as advertised, go ahead and send me a fix.

As soon as ACPI is fixed I will make a version of wmapm for Linux ACPI. But until it works on MY laptop (toshiba satellite 2545xcdt) dont expect me to do anything about it. I will not accept patches either.

tk_docapp project is a small GUI for mounting devices and ACPI energy monitoring under NetBSD.

User of other *nix operating systems can only use the mount option.

wmlaptop is a WindowMaker dockapp able to satisfy any requirements of a linux user with a laptop.
The smartest should have easily guessed that wmlaptop includes an advanced battery information interface, including an indicator which estimates the remaining battery autonomy.
Main features:
- Battery estimated time remaining
- Multi Batteries support
- Battery remaining charge (visual and percent)
- Auto-Frequency Scaling
- Manual Frequency Scaling
- 0-100 Cpu Load indicator
- APM and ACPI support
- sysfs and /proc filesystems support
- Kernel 2.6 series fully compatible
- Visual support for multiple batteries
- "Visual and audio" alarm on Low-Battery
- Auto shutdown on Low-Battery
- Easy screen saver starter
- Console executable
- Longrun Transmeta Cpu support
Enhancements:
Added: Makefile.Longrun src/longrun.h src/lungrun_linux.c, src/longrun_freebsd.c
Updated: src/main.h src/cpu.c src/init.c src/event.
Implemented support for Transmeta CPUs with Longrun capability. On these systems you set a range of frequencies (actually "performance levels") and the system will automatically adjust within the range based on CPU load (like the auto-freq function but hundreds of times per second). The support works as follows:
-The arrows shift the maximum performance level up and down by one unit. The minimum always stays at 0 (which is equivalent to, e.g., 300 MHz on a 1 GHz CPU).
-If "auto-freq" is turned on, the range is set to (0, max), otherwise it is set to (max, max).
-Theoretically code could be added to adjust the shift size based on right-clicks on the arrows, but with only 5 levels typical on a CPU, this isnt a high priority.
-On startup, the setting is set to 0,current, current,current depending on auto-freq state, where min or max is used in place of current if min or max setting is requested. Note that this and subsequent adjustments may not interact well with other processes or daemons adjusting longrun state, such as an acpid script.
src/main.c
fixed bug whereby dont-blink setting in argsConfig.h was being ignored.
src/main.c src/main.h src/event.c src/battery.c
added cpuUpdate and batteryUpdate options/defaults so update rates can be configured.
src/pixmap.c
is now possible to choose among 3 type of skin
