=== HDAPS - IBM Active Protection System Linux Driver ===
This is the Linux driver for monitoring the accelerometer known as [[Active Protection System|IBM Active Protection System]].

The driver only enables reading of the acceleration data. It does '''not''' perform [[#Harddisk Protection|automatic disk head parking]]. But there are already some other useful [[#Applications|applications]] for HDAPS, using the {{path|/sys}} interface it provides.

{{WARN|There are two versions of the hdaps driver, one in the Linux kernel mainline, and another provided by [[tp_smapi]]. '''Use of the tp_smapi version of hdaps is strongly recommended by the current hdaps developers.'''}}
|}

=== Features ===
*provides accelerometer values via sysfs
*provides a joystick type input device

=== Project Homepage / Availability ===
*[http://hdaps.sourceforge.net/ Project Homepage]
*The driver is included in the 2.6-mm series of kernels since August, 26th 2005.
*The driver is now in the mainline (2.6.14).
*The [[tp_smapi]] package contains some patches to this driver. These are necessary for some recent models, and recommended for all.

=== Status ===
A driver is included in recent Linux kernels and is actively maintained, but it is very inferior to the driver in tp_smapi (which provides its own hdaps module).

=== How to install the driver ===
Recent Linux kernels include the <tt>hdaps</tt> driver. However, the driver in the mainline Linux kernel has two problems with recent models:
* It doesn't whitelist them (you have to edit hdaps_init() in drivers/hwmon/hdaps.c to include a line like <tt>HDAPS_DMI_MATCH_LENOVO("ThinkPad T60")</tt>)
* It doesn't work reliably, e.g., it may read out constant values (0,0). See [http://sourceforge.net/mailarchive/message.php?msg_id=15350314 here].

To solve both problems, install the modified hdaps that is bundled with [[tp_smapi]].

=== Harddisk Protection ===
As mentioned above, the hdaps kernel driver is only responsible for reading the accelerometer data and exporting it through the sysfs interface. In order to use this information to protect the disk, some additional steps are required.

See [[How to protect the harddisk through APS]].

=== Input device support ===
In more recent versions of the Linux kernel, the hdaps exports event devices with the accelerometer data. These devices can be used as-is by some programs (e.g. hdapsd), but for most they must be handled by the additional kernel module <code>joydev</code>.

When both modules are loaded, joydev will provide standard joystick device emulation for hdaps (standard hdaps exports just one joystick device. enhanced hdaps from tp_smapi will export two due to issues still unsolved on joydev, but the second one must not be used as a joystick).

{{WARN|Letting a program bind to these joystick devices can cause surprising results if you are not aware of it. e.g.: mplayer can act quite strangely. Also, letting a program bind to the second joystick device from enhanced HDAPS is guaranteed to be trouble}}

Udev can be used to create device nodes in /dev for use by user space programs that access the joystick, and to set appropriate permissions.

In order for non-root users to access these device files, their permissions must be tweaked a little through an appropriate udev rule and corresponding "joy" group.

{{cmdroot|addgroup joy}} 
{{cmdroot|adduser <you> joy}} 
<code># echo 'SUBSYSTEM=="input", KERNEL=="js*", MODE="0660", GROUP="joy"' >> /etc/udev/hdaps-joy.rules</code> 
{{cmdroot|ln -s ../hdaps-joy.rules /etc/udev/rules.d/z60_hdaps-joy.rules}} 

Programs you can use to test and calibrate the device files include <code>jscalibrator</code> (gui) and <code>jstest</code>/<code>jscal</code> (cli) packaged together (at least in Debian) simply as "joystick".

=== Applications ===
====Disk head parking====
You will need the kernel patch below and the hdapsd userspace daemon. The GUI monitoring is optional.

See [[How to protect the harddisk through APS]] for more information.

===== Kernel patch =====
Due to significant changes in the way the libata module which handles disk i/o, applying any of the currently available patches to kernel 2.6.24 will intermittently cause system hangs when the queue is frozen (i.e., the heads are parked). It is recommended either that you stay at kernel [http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.23.17.tar.bz2 2.6.23] or do without disk protection in 2.6.24 until the kinks have been worked out. There has been significant work on the part of [http://lkml.org/lkml/2008/2/25/478 Elias Oltmanns], author of the more recent patches, to get this worked out and eventually get shock protection built into the mainline kernel.

Below are some links to patches for various Linux kernel versions. As noted above, your mileage may vary with the 2.6.24-rc3 patch as it was after this release candidate that things stopped working nicely.

===== Userspace daemon =====
*[http://article.gmane.org/gmane.linux.drivers.hdaps.devel/1372 Current version] 
This version optionally reduces timer interrupts (as measured by [[PowerTOP]]), and thereby reduces power consumption on modern ("tickless") Linux kernels. Interrupt reduction requires the <tt>hdaps</tt> kernel module from [[tp_smapi]] 0.32 or newer, and a udev rule. If these are not present, it will default to an older polling method that is slightly more power-hungry. The udev rule helps hdapsd find the input device, and on most distributions it can be created as follows:
# echo 'KERNEL=="event[0-9]*", ATTRS{phys}=="hdaps/input1",ATTRS{modalias}=="input:b0019v1014p5054e4801-*",SYMLINK+="input/hdaps/accelerometer-event"' \
> /etc/udev/rules.d/51-hdaps.rules
Then reboot or run {{cmdroot|/sbin/udevtrigger}}, and verify that the {{path|/dev/input/hdaps/accelerometer-event}} symlink exists.

*[ftp://rohrmoser-engineering.de/pub Modified adaptive algorithm version] - uses a different (and potentially better) algorithm for the adaptive sensivity threshold.

===== GUI monitoring =====
*[http://roy.marples.name/node/269 khdapmonitor] KDE System Tray Monitor
*[http://www.dresco.co.uk/hdaps/gnome-hdaps-applet-20060120.tar.gz gnome-hdaps-applet] visual display of disk protection status in gnome panel

Talk:Tp smapi

Roam: Comment about T60 invert parameter.

== Feedback ==

Great, great work! Really! This completely rocks. I just stopped my battery from charging at 77% and restarted charging a bit later, no problems whatsoever. BTW, this is on kernel 2.6.14.3.

None of the fuctions is working on my T40, kernel 2.6.14-mm2.

Works for me on a T41 running 2.6.12-10-686 (Ubuntu 5.10).

--[[User:berndtnm|berndtnm]], 2005.12.06

Including stop_charge_thresh? That one seems to be missing on the T42p.

tp_smapi works just fine on an R52 with Ubuntu Breezy stock kernel.

''To set the thresholds for starting and stopping battery charging (in percent of current capacity):''

'''current''' really? That'd be weird, I'd expect it to be percent of '''total''' capacity.

--[[User:Micampe|Micampe]] 14:39, 7 Dec 2005 (CET)

"Current full charge capacity", as opposed to "current remaining capacity" or "designed full charge capacity"...

Battery features don't work with my T41p. I can't check this with windows. Can anybody try these features?

Nils, does cdrom_speed work for you on the T41p? Could you provide the details requested in the README (dmesg etc.)?

--[[User:Thinker|Thinker]] 21:57, 7 Dec 2005 (CET)

CDRom Speed seems to work. (I see no warnings, but I have to do a speed test.) Now, I've send all outputs to the email-address in the readme.

-- Nils, 8 Dec 2005
----

All the features except the stop_charge_thresh seem to work here on a t42p.
One note, the start_charge_thresh seems to really be stop_charge_thresh. Ie, If I set that to lower than my current battery %, it will never charge,
and if I set it to 100 the battery charges all the way.

--[[User:Nirik|Nirik]] 16 Dec 2005
----

Nirik, "all the features" as of which version? For example, do the force_discharge{1,2} in tp_smapi 0.12 also work for you? See the table in the article page. About start_charge, that's odd. Can you send me a log of what you did, what was the result a what was the dmesg output for each operation?

So it seems force_discharge1 is not supported at all. But force_discharge2? By the way, i think wiki is a _very_ good idea for collecting information, but not for discussion. I would prefer a maillinglist. We can use sourceforge.

--[[User|StefanSchmidt]]

force_discharge2 is indicating a real error condition (bx=2103 which has bit 0x02 on), but I have no idea what the error is or how to fix it. Sorry. If you can trigger this function under Windows and have SoftICE or equivalent, maybe it can be worked out.

About the Wiki discussion, I'm not sure a mailing list is justified yet, but you can use the linux-thinkpad list or the e-mail address in the README.

--[[User:Thinker|Thinker]] 21:42, 16 Dec 2005 (CET)

OK, then i use linux-thinkpad to get more people involved. I'am away the next weeks, but i hope to find some time to hacking on tp_smapi.

To confirm:
tp_smapi 0.13 works with hdaps module loaded on T41 (2373-8RG). However, force_discharge*, inhibit_charge_minutes, start_charge_thresh, stop_charge_thresh don't seem to be implemented on this model.

tp_smapi version 0.13 with T23 (2647-3QG) (I have dual batteries)...

However, all the battery status information is available, and functions appear for both BAT0 and BAT1, regardless of when the UltraBay battery was inserted or ejected- this is very useful, it is the only way I can monitor my UltraBay battery unless it was present on boot.

0x1610 is the number of an IO port it writes to, so changing it to a random number will pretty much guarantee a system crash...

The only way I can think of for figuring out the T22 interface is to see what the Windows software does.

== Kernel Patch? ==

Hello Thinker,

would it be possible to provide the SMAPI support as kernel patch as well? Something along the lines of: (0.12 against 2.6.15-rc5)

''(deleted, see below for how to create a patch file)''

Deleted the tp_smapi.c file at the end, out of obvious reasons, and I'm not sure about the placement in the ACPI section, OTOH there it would be found easily next to ibm_acpi.

Providing a patch would help when recompiling the kernel often, I hate recompiling external modules every time (even got me a kernel-upgrade script to do most of it automatically). But of course it's up to you. :)

--[[User:Spiney|spiney]] 09:52, 16 Dec 2005 (CET)
----

I'll be glad to add this, but I don't want to go through additional manual steps in the release process (there are already quite a few). Can you add a "make patch" functionality to the Makefile, or something of the sort, to automatically generate a full patch (including tp_smapi.c) against current kernel sources?

Also, this shouldn't be under drivers/acpi, since it doesn't use ACPI at all (that's why I didn't make it a patch to ibm_acpi). I think the right place is drivers/firmware, like the dell_rbu driver for Dell laptops.

BTW, the convention for kernel patches is to start them once level higher:
diff -Nurp kernel-2.6.14-vanilla kernel-2.6.14-patched

--[[User:Thinker|Thinker]] 17:12, 16 Dec 2005 (CET)
----

Of course it's from the wrong level, as usual I was just lazy/inattentive. And at one point I'll remember who likes what patch format, promise. ;)

A patch target as in "create a new file holding a correct diff to current kernel source" would be rather difficult, since line numbers might change etc., but applying the patch should be straighforward with a bit of sed. Of course I could just do that, create a patch with the diff command and then apply the new patch file in reverse. ;)

--[[User:Spiney|spiney]] 18:36, 16 Dec 2005 (CET)
----

If it does that on a local copy (no changes the original kernel tree) and cleans up after itself, that's fine with me. :-)

--[[User:Thinker|Thinker]] 18:50, 16 Dec 2005 (CET)
----

Ok, here's a shell script that creates the patch, feel free to use it under the terms of the GPL. For example call it from your Makefile with the patch target: (I didn't want to put all the script into the Makefile, since the rules about escaping in Makefiles, well, escape me ;)

Ah, neat sed foo. How about [http://tpctl.sourceforge.net/tmp/Makefile this] escapade, then?

What's the sed spell needed to replace the Makefile's
VER := 0.13

--[[User:Thinker|Thinker]] 20:37, 16 Dec 2005 (CET)

Hmm, something like
VERFROMC=$(sed -ne 's/^#define TP_VERSION "$.*$"/\1/gp' tp_smapi.c)
sed -i -e "s/^VER := .*$/VER := $VERFROMC/" Makefile
should do (untested, from the top of my head, maybe the temporary variable isn't even necessary?). And neat Makefile wizardry, at one point I'll learn the syntax.

==Installation questions==
Amazing! I've loaded this module in my T43 which is running SuSE 10 with the kernel of 2.6.13-15. I have three points to share:

1. The battery control part seems to work but has a minor problem. I set the stop_charge_threshold to 70, but the battery stops charging at 55%. Don't know why and how to fix it. :P

2. I don't have the cd speed control function. Here is what I have under /sys/devices/platform/smapi/:

./ ../ ac_connected BAT0/ BAT1/ bus@ driver@ power/

3. SuSE 10 doesn't have the necessary C files under .../drivers/hwmon/, I copied them from a 2.6.14.5 kernel source. Maybe it causes the two problems above. :(

When I have time, I'll install the new kernel to see if the problems are gone and report the result.

--[[User:68.51.153.96|68.51.153.96]] 04:31, 2 Jan 2006 (CET)

1. It should stop charging at 70, but will only ''start'' charging when remaining capacity has dipped below <tt>start_charge_thresh</tt>.

2. See the note about PROVIDE_CD_SPEED.

3. That's should be needed only for patching the HDAPS driver in order to make it compatible with tp_smapi. If your kernel (which version is it?) doens't inlude the HDAPS driver anyway, you don't need to patch....

--[[User:Thinker|Thinker]] 09:28, 2 Jan 2006 (CET)

Thanks Thinker.

1. I discharged and recharged the battery again. This time, it stops at 68% percent, which is pretty good.

2. I missed the NOTE in README, for I just followed this wiki. :P

3. My kernel version is 2.6.13-15.

By the way, I just got this T43 whose model number is 266896U. I feel that the noise of the fan is much louder than my previous T21. I think it is so since it has a CPU with bigger power but am wondering if other T43 has the same big noise?

--[[User:Tyne|Tyne]] 00:14, 3 Jan 2006 (CET)

The note about PROVIDE_CD_SPEED is also in the Wiki...

About the T43 fan noise: yes, this is a very common (and annoying) problem. See [[Problem_with_fan_noise]] and our [[ACPI fan control script]], and send Lenovo a complaint in hope they'll fix this at the firmware level.

There must be something fundamentally wrong with the makefile. I have for example never seen that a symlink has to point from /lib/modules/someversion/somewhere to /usr/src/linux. I have installed other modules in the past and they all worked with installed linux-headers package. I didn't ever have to download 40MB kernel source, unpack it, configure it to have a .config and compile the whole kernel just to have 2 or three of the other files needed. This cannot be the correct way to install a driver.

Wyrfel, that was some heavy editing you did... I agree with most changes (including the saner color choice). I did like those HINT floats, though - they keep the hints from interrupting the flow of text too much, and this particular text needs any help it can get.

Hei Thinker,

I'll look into it again. I felt that the floating HINTs were tearing the text apart too much. Maybe we could fix it by placing the clear marks somewhere else.

== Dual battery operation with tp_smapi ==

It looks like it is working quite fine with tp_smapi-0.13 and 2.6.15 (it may also work with other versions, but those are the ones I have running right now).

The juicy details:

{{cmdroot|cd /sys/devices/platform/smapi/}}
{{cmdroot|cat ac_connected}}

{{cmdresult|0}}
{{cmdroot|cat BAT{0,1}/state}}
{{cmdresult|discharging}}
{{cmdresult|idle}}

{{cmdroot|echo 1 > BAT1/force_discharge1}}
{{cmdroot|cat BAT{0,1}/state}}
{{cmdresult|idle}}
{{cmdresult|discharging}}

Checking capacity values shows that the corrent battery is being depleted.

And remember, before you yank the CD/DVD drive out, issue:

{{cmdroot|cat eject > /proc/acpi/ibm/bay}}

----

Great! Which ThinkPad model is it? Could you also {{cmdroot|cat /sys/devices/platform/smapi/BAT{0,1}/force_discharge2}} and report the dmesg output (after {{cmdroot|make load}} or {{cmdroot|1=modprobe tp_smapi debug=1}})?

About the eject command, I think it should be possible to do that automatically when the Ultrabay handle is ejected, via <tt>acpid</tt>.

--[[User:Thinker|Thinker]] 15:45, 10 Jan 2006 (CET)
----

It's a T43 (2669). cat'ing force_discharge2 gives me an I/O error and I see

tp_smapi: cannot get force_discharge2 of battery 0: bx=2103

tp_smapi: cannot get force_discharge2 of battery 1: bx=2103

I find these errors irrelevant from the user's point of view, though.

Indeed, it should be possible to automatise the "eject" command. I should also be noted that once a force_discharge1 is set, it will NOT unset automatically, event when the AC is plugged back in. An obvious fix is to fiddle with the appropriate ACPI event to force_discharge1 back to 0 for all batteries once the AC is attached.

----

Thanks, this eliminates the last situation I imagined <tt>force_discharge2</tt> might work. The next tp_smapi version will remove <tt>force_discharge2</tt> and rename <tt>force_discharge1</tt> to <tt>force_discharge</tt>.

If you write those ACPI scripts, it would be great if you put them on the Wiki.

--[[User:Thinker|Thinker]] 16:31, 10 Jan 2006 (CET)

Well, I still do not preclude the fact that <tt>force_discharge2</tt> may be useful for something else on other models.

Hei Thinker,

i just renamed the new page. Will adjust your links later on. Keeping the redirect page until that's done. Please set any new links you create to the new page (the pages of the individual UltraBay batteries should contain a pointer).

On a sidenote: I would like to split the SMAPI support under Linux page into a tp_smapi driver page, just listing the features, and a "How to use tp_smapi" page. I would also split the thinkpad/tpctl page off that again. Any objections?

[[User:Wyrfel|Wyrfel]] 20:42, 10 Jan 2006 (CET)

ACK about the page rename (the old one did sound a bit out of line to my ear, but I couldn't spot why...).

About the splitting tp_smapi vs. thinkpad/tpctl, no objection.

About splitting tp_smapi: currently most of that section doubles as both a spec and a HOWTO, which I think is a convenient and concise way to describe things (hey, it must be right, the Perl docs do it!). I'm not sure there's much benefit in duplicating that. Perhaps we should wait for a critical mass of additional lore to accumulate?

For at least the T series i think that charge control was not supported prior to the T42, hardware/BIOS side. Perhaps "N/A" flags would be better here?

I also created <nowiki>{{Isup}}</nowiki> style templates for status, they just include images, like {{Isup}}.
Not emotional about it, just wanted to let you know in case you want to use them.

Third and last...would it possibly be better to make the table headers more human readable like i.e. "lower charge threshold" or something like that instead of "start_charge_thresh"?

[[User:Wyrfel|Wyrfel]] 19:21, 11 Jan 2006 (CET)
----

About "N/A", sure, if we get reliable data about the hardware capabilities. Alas, most negative reports were just "it doesn't work", and in some cases gave contradictory information (SMAPI interface says a function is unsupported but user says it works under Windows).

About {{Iyes}} and friends, they're very cute, but I think think they're harder to parse visually and would add some clutter to an already dense table.

The table headers are just the names of the control files - that's important to keep, sine it's the most natural lookup key. Adding friendly description would be great, if we can fit them in (not everyone has an SXGA+ display...). I tried and failed.

My X40, kernel 2.6.16 and tp_smapi 0.20. I try to set the thresholds to 40% and 90% using:
<pre>
# echo 90 > stop_charge_thresh
# echo 40 > start_charge_thresh

== Battery daemon feedback requested ==

I am writing a battery-management daemon to control charging and discharging BAT0 and BAT1 in accordance with usage patterns that extend Li-Ion and Li-Py battery life.

By default, the machine fully discharges BAT1 first, and it is said that deep-cycling all the time dramatically shortens their lifetime.

My Z61t is the test machine, and it is configured with two batteries, the stock 4-cell, and an "Advanced Ultrabay", which about doubles the runtime of the machine.

Currently there are two "modes" of the daemon:

Discharging mode.
<pre>
* look at the "remaining_percent" values for both batteries
* if one is more than THRESHOLD percent less than the other one,
force discharge from the battery with more capacity left
(the current value for THRESHOLD is 10%)
</pre>
I believe the preceeding will prevent either battery from being deep-cycled disproportionately.

Charging mode. I am less sure what the "right" algorithm is here. The following is a proposal.
<pre>
* look at the "remaining_percent" values for both batteries
* if one is more than THRESHOLD percent less than the other one,
force charging to the battery with less capacity left
* honor pre-set values in stop_charge_thresh and start_charge_thresh
</pre>

I would like to get feedback in the form of "better" algorithms or requests for this daemon.

--[[User:Zak Smith|Zak]] 19:03, 12 September 2006 (CEST)

It sounds like your algorithm will indeed minimize wear on both batteries. A side benefit is that charging will toggle between the batteries, which may help keep them cooler while charging and thus prolong their life. OTOH, if you plan to occasionally swap the UltraBay battery for other devices, you may want to fully charge the system battery (up to stop_charge_thresh) first.

--[[User:Thinker|Thinker]] 22:57, 12 September 2006 (CEST)

I have noticed that when force_discharge is set and the batteries switch, the gnome battery monitoring applet gets totally confused about remaining runtime. Besides being a nuisance, this could presumably cause premature emergency shutduwn.

I have also noticed that the reported remaining runtimes vary greatly between acpi, the applet, and /proc/acpi/battery/*/state

--[[User:Zak Smith|Zak]] 21:46, 14 September 2006 (CEST)

What do you mean by "acpi" vs. "/proc/acpi/battery/*/state"?

The most accurate readout is probably {{path|/sys/devices/platform/smapi/BAT0/remaining_running_time}}, but I don't think any applet uses that yet.

--[[User:Thinker|Thinker]] 12:07, 15 September 2006 (CEST)

By acpi, I meant the output of the acpi (1) command. I'll get some comparative numbers later and post them here.

Have you developed this further since then? I just got my first dual-battery-setup for my Z60m. Anyway, it says it doesn't support hotplugging the battery? What does this mean? Do things break if I change batteries or switch a DVD drive to the ultrabay slot while it's running?

Anyway, I deciphered your source code enough that it basically seems to poll the stuff under /sys/devices/platform/BAT?/* every 10 seconds. Anyway, I don't see what's so tough about hotswapping - the BAT1 directory does not seem to vanish either by issuing echo 1 > /sys/devices/platform/bay.0/eject or just yanking it out. The /sys/devices/platform/BAT1/installed goes to zero though.

Can you add a check to the condition if (b0->on_ac == 0) ...change this to

if ((b0->on_ac == 0) && (b0->installed == 1) && (b1->installed == 1))

then the equal discharging logic would handle hotswapping too (ie. situations where you're running only on 1 battery instead of 2).

I hope you keep on honing this.

One of the few things I miss from Dell is that when operating with dual batteries, it discharges both of them evenly.

== X60: tp_smapi 0.31 with kernel 2.6.20 issue ==
[[category:X60]]
1st of all: Thanks alot for your work. I do really appreciate this (tp_smapi/thinkwiki).

2nd: On a Debian (testing) w/ vanilla 2.6.20+tp_smapi+hdaps (w/ modules loaded) the kernel panics (init oops) on reboot just before resetting the system. It has a minor impact, you need to press power-off for 5 secs to switch off the machine. Just FYI.

--[[User:Runia|Runia]] 23:48, 16 April 2007 (CEST)

Is this consistently reproducible? What's the oops message and stackdump (you can snap a digicam shot)? Does this happen when...
* rebooting with tp_smapi loaded but hdaps not loaded?
* rebooting with neither tp_smapi nor hdaps loaded?
* rebooting with vanilla hdaps loaded (instead of the tp_smapi version)?
* removing just these modules ("rmmod") instead of rebooting?

== battery start/stop thresholds saved after reboot? ==

Hi

Are the values in stop_charge_thresh and start_charge_thresh just used when Linux is running, or are they saved in the battery? Here after a reboot the values are reset to 96/100. I set these values to 40/85 shut the thinkpad down and charged the battery - sadly it did not use the 85% setting and charged the battery to 100%.

--[[User:Burp|Burp]] 15:31, 13 March 2007 (CET)
----

The thresholds are saved in the embedded controller, which keeps them as long as there is AC or battery power. If you take away both, the state is reset. If you use suspend-to-disk, tp_smapi will remember the threholds and restore them during resume; but you'll need to write your own init script to set the thresholds during normal reboot after full power loss.

--[[User:Thinker|Thinker]] 16:19, 13 March 2007 (CET)
----

Under Ubuntu, you can set the thresholds under {{path| /etc/default/tpsmapi-utils}}.

START_CHARGE_THRESH_BAT0=40
#START_CHARGE_THRESH_BAT1=40

STOP_CHARGE_THRESH_BAT0=95
#STOP_CHARGE_THRESH_BAT1=70
----

If I set the value, plug in in the power cord to charge it after I have shut down the thinkpad, it will charge to 100%?
So I have to plug in the power cord while the thinkpad is running and then shut it down to make it work?

If I want the thresholds to be regarded I have to plug in the power cord when the thinkpad is running and then shut it down. If I turn it off before connect it to AC, the values are ignored.
So, are the values only saved in standby-mode? This isn't clear for me, and I think I'm not alone with it ;)

--[[User:Alexb|Alexb]] 20:56, 15 March 2007 (CET)

The values are not '''saved''' anywhere. They are set on the EC, and as long as the EC is kept powered on and not rebooted, they are retained. Sleep cycles and reboots on the main machine do not affect the EC. An EC firmware upgrade reboots the EC. Powering off the ThinkPad while it is on battery also powers down the EC. The ThinkPad does not power down the EC while on AC (it has to be powered up to charge the batteries).

I hope that answered all your doubts...

--[[User:Hmh|hmh]] 04:45, 28 March 2007 (CEST)

On my x61s, these values are remembered after powering off the ThinkPad while it is on battery. I didn't try to remove the battery. But it looks like the x61s behaves as Thinker described, not as Hmh did.

--[[User:Jannic|Jannic]] 13:58, 3 November 2007 (UTC)

Curious. That would mean the x61s does not power off the EC even while on battery and powered off, or that it is storing the SMAPI thresholds away in CMOS. Care to test it? If you want to check that theory, just hexdump /dev/nvram, change a threshold, than hexdump it again...

--[[User:Hmh|hmh]] 12:09, 11 November 2007 (UTC)

Seems like it's the former choice: I didn't see any nvram changes after changing the thresholds. Shutting down the system while on battery does not reset thresholds. Shutting down while on battery and then removing the battery does reset them to start_charge_threshold=96, stop_charge_threshold=100, though. I guess they put the EC in some low-power sleep mode while the notebook is turned off and on battery. The specs linked from [[Embedded_Controller_Chips]] list sleep mode currents below 5µA, which is probably negligible compared to self-discharge of Li-Ion batteries.

== stop_charge_thresh on t42p ==

Hi,

'cat /sys/devices/platform/smapi/BAT0/stop_charge_thres' does not work. I get:
'Function not implemented'. Under windows the ibm tool shows me both thresholds. I am using tp_smapi version 0.31 with kernel 2.6.20 (ubuntu feisty).

----

Same problem, I want to know what I can do to help figure out why this works in windows and not with tp_smapi. I am running tp_smapi 0.32 on 2.6.20 Ubuntu Feisty (7.04) Here is the debug output from tp_smapi.

Looks like the T42(p) is using a different SMAPI interface for the stop threshold. For example, it could be using the same interface as inhibit_charge_minutes_interface, and monitoring the charge levels manually. Maybe you can use a debugger (e.g., SoftICE) to find out what SMAPI calls are made when you change the thresholds under Windows.

--[[User:Thinker|Thinker]] 17:40, 13 August 2007 (UTC)
----

What BIOS and EC version? If a T42/p is doing this, all the T4X but the two T43 types should also suffer the same problem... Not to mention a bunch of R5x models, etc (BIOS TP-1R).

--[[User:Hmh|hmh]] 23:17, 13 August 2007 (UTC)
----

This is copy and pasted from the DMI info I put on the DMI list page yesterday:
1RETDPWW (3.21 ) 06/02/2006 Handle 0x0029, DMI type 11, 5 byte String 1: IBM ThinkPad Embedded Controller -[1RHT71WW-3.04 ]-

I just noticed that the T40 through the T42p use this EC model. The T43s are different. No one with a T40-T42 has claimed success with the stop_charge_thresh on the tp_smapi status table.

I will try to get windows on a harddrive and pop it in my t42p to use softICE or whatever debuggers soon.

--[[User:Airbornespent|Airbornespent]] 15:39, 15 August 2007 (UTC)
----

I've installed windows, I can again confirm that the start and stop thresholds work with the maximiser. I couldn't seem to find softICE but I got a debugger called syser. I have no clue what I should be looking for though, a certain set of CPU calls, addresses, etc? Any advice would be great. If you are more familiar with softICE I will find and install that.

I just had an idea though. Maybe I can set the thresholds to known values in windows, and then reboot to linux without removing the AC, then the thresholds would be saved on the EC. Is there then a way I can dump the settings in linux and if I do this with several known thresholds that might be enough information to figure this out?

--[[User:Airbornespent|Airbornespent]] 19:48, 15 August 2007 (UTC)
----

You need to trace the SMAPI calls made when the thresholds are changed. You can look at tp_smapi.c or the vanilla kernel drivers/char/mwave/smapi.c to see how SMAPI work. Basically, the parameters are loaded into registers, with the SMAPI function code in register EBX. Then, a byte is written to IO ports 0xB2 and 0x4F. The write to port 0xB2 invokes the BIOS SMAPI code in SMM mode. So the first thing to check is what SMAPI functions are called, i.e., the value of EBX before each wrote to port 0xB2. You can see some of the known codes in the SMAPI_* constants near the top of smapi.c.

== Does smapi interface include communication with eeprom? ==

There exists a windows program (which I haven't tracked down yet) which will reset the eeprom in the battery to clear an error. Could the smapi interface do the same?

Or are there other ways to do this? I have a relatively new battery (< 10 cycles) with all my tests showing the cells are fine, but since it reports "damage" to the thinkpad, it won't charge it.

----

No. Can you provide a link to that Windows program and (more important) information about how it works?

--[[User:Thinker|Thinker]] 02:17, 25 June 2007 (UTC)
----

Acc plus v1.3 [http://www.microsys.ro/accplus.htm] communicates over SMBus via a parallel port adapter. It says it can reset the eeprom via direct connection to the chip. But version 1.4 claims to be able to reset the chip via SMBus. I haven't verified this claim because only v1.3 is available for download. But I figured anything that can be done via the parallel port adapter ought to be able to be done natively by the thinkpad.

The Smart Battery Workshop also claims to be able to reset the eeprom. This is the program that is hard to track down because all the links you find are broken. I finally found it by searching for "smart battery workshop" on download.com [http://download.com]. They use those random urls so I can't post a direct link.

In summary: mostly these programs are just a way to communicate with the battery over SMBus using a parallel port. But there's the tantalizing claims of being able to reset the chip too....

--[[User:Kdnelson|Kdnelson]] 03:14, 3 August 2007 (UTC)
----

If I read this correctly, both AccPlus and Smart Battery Workshop require you to take out the battery and communicate with it via a parallel-to-SMBus adapter. This is out of scope for tp_smapi. AccSmart probably uses the Smart Battery interface through the laptop's internal SMBus bus; this is already supported by Linux's smart battery drivers, but doesn't work on ThinkPads since we don't know of any way the CPU can directly access the SMBus.

== kernel 2.6.24 compatibility ==

Version 0.32 of tp_smapi seems to be incompatible with the prereleases of 2.6.24. Does anybody know if there are updated patches available?

--[[User:Jannic|Jannic]] 13:13, 1 November 2007 (UTC)

Update: It were the renames of BIT() to BIT_MASK in commit 7b19ada2ed3c1eccb9fe94d74b05e1428224663d which did not
apply cleanly to my tp_smapi patched tree. This looks like a minor change which should be fixable easily.

Roam: Add another T60 Model

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |
The <tt>tp_smapi</tt> kernel module exposes some features of the ThinkPad hardware/firmware via a <tt>sysfs</tt> interface. Currently, the main implemented functionality is control of battery charging and extended battery status. It also includes an improved version of the [[HDAPS]] driver. The underlying hardware interfaces are [[SMAPI support for Linux|SMAPI]] and direct access to the embedded controller.

For older ThinkPad models, see also [[tpctl]].

{{WARN|This driver uses undocumented features and direct hardware access. It thus cannot be guaranteed to work and could conceivably damage your computer (though so far no incidents have been reported).}}
|}

===Features===
*Battery charge/discharge control
*Battery status information

===Project Homepage / Availability===
* Project page: http://tpctl.sourceforge.net/
* You need to [http://sourceforge.net/project/showfiles.php?group_id=1212&package_id=171579 download] only the <tt>tp_smapi</tt> package.

===Installation===
====Installation from source====
You will need the kernel headers and makefiles corresponding to your current kernel version. On {{Fedora}}, this means {{cmdroot|yum install kernel-devel-$(uname -r)}} .

:{{cmdroot|tar xzvf tp_smapi-0.34.tgz}}
:{{cmdroot|cd tp_smapi-0.34}}

Then, either compile and load the driver within the current working directory (for testing):
:{{cmdroot|make load}}
OR compile and install into the kernel's module path:
:{{cmdroot|make install}}

If you use the [[HDAPS]] driver, add <tt>HDAPS=1</tt> to also patch the <tt>hdaps</tt> for compatibility with <tt>tp_smapi</tt> (this requires a kernel source tree matching the current kernel).
Again, either load the driver within the current working directory:
:{{cmdroot|1=make load HDAPS=1}}
OR install into the kernel's module path:
:{{cmdroot|1=make install HDAPS=1}}

To prepare a stand-alone patch against the current kernel tree (including
a patch against <tt>hdaps</tt> and new <tt>Kconfig</tt> entries):
:{{cmdroot|make patch}}

To delete all autogenerated files:
:{{cmdroot|make clean}}

The original kernel tree is never modified by any these commands.
The {{path|/lib/modules}} directory is modified only by {{cmdroot|make install}}.

====Installation in Gentoo====
The {{Gentoo}} portage system carries a [http://packages.gentoo.org/packages/?category=app-laptop;name=tp_smapi tp_smapi package], which follows the latest version pretty closely. On a Gentoo system, you can install and load as follows.

If you use the [[HDAPS]] driver, do this first:

* Configure <tt>hdaps</tt> as module in your kernel
* Add the <tt>hdaps</tt> use flag in {{path|/etc/make.conf}}
* {{cmdroot|rmmod hdaps}}

Then:

* {{cmdroot|emerge tp_smapi}} (or install tp_smapi with hdaps support manually, as above)
* {{cmdroot|echo "tp_smapi" >> /etc/modules.autoload.d/kernel-2.6}}
* {{cmdroot|echo "hdaps" >> /etc/modules.autoload.d/kernel-2.6}}

Then reboot, or run:
* {{cmdroot|modprobe tp_smapi}}
* {{cmdroot|modprobe hdaps}}

====Installation on Debian unstable (sid) or testing (lenny)====
Debian now contains the [http://packages.debian.org/tp-smapi packaged module source] for use with module-assistant.

* {{cmdroot|apt-get install tp-smapi}}
* {{cmdroot|m-a -t a-i tp-smapi}}

====Installation on Ubuntu/Debian====
Installation on Ubuntu or Debian is quite easy, but there are a few things to look after:

To get your system ready for compiling code, install the build-essentials (as root, of course, as all of the following comands; Ubuntu users have to prepend 'sudo' to every line and enter their own password when prompted):
<pre><nowiki>apt-get install build-essential</nowiki></pre>

To get tp_smapi to work, obtain the latest source as mentioned above and unpack it. If you want to use HDAPS, you need to install the kernel source matching te kernel you are running. To do so, issue this:
<pre><nowiki>uname -r</nowiki></pre>
This will give you the version of your current kernel. As Ubuntu adds '-generic' to the kernel-version, the following command works for Debian users only:
<pre><nowiki>apt-get install linux-source-`uname -r`</nowiki></pre>
Ubuntu users use the kernel-version they got by the command before, e.g. 'linux-source-2.6.20'

Now change to the tp_smapi dir:
<pre><nowiki>cd tp_smapi-X.YY</nowiki></pre> (X.YY being the version-number of [[tp_smapi]])
and make and install tp_smapi as instructed above.

If you get an error that the kernel version isn't matching (or that you need to set KSRC/KBUILD), please check that there is a symlink from the modules dir to the kernel source:
<pre><nowiki>root@localhost:~#ls -l /lib/modules/2.6.20-16-generic
lrwxrwxrwx 1 root root 28 2007-02-02 08:39 source -> /usr/src/linux-source-2.6.20</nowiki></pre>
Create the link if the line above is not existent:
<pre><nowiki>root@localhost:~#ln -s /usr/src/linux-source-2.6.20 /lib/modules/2.6.20-16-generic/source</nowiki></pre>

Now the following will build and install the correct modules to their locations:
<pre><nowiki>make install HDAPS=1</nowiki></pre>
To make sure your system loads the modules at boot time, do this:
<pre><nowiki>echo "tp_smapi" >> /etc/modules
echo "hdaps" >> /etc/modules</nowiki></pre>
and update your initramfs:
<pre><nowiki>update-initramfs -u</nowiki></pre>

To get tp_smapi running now, just load the modules:
<pre><nowiki>modprobe -a tp_smapi hdaps</nowiki></pre>

This description was tested on Kubuntu 'Feisty Fawn' and should work on all Debian-based distros with minor tweaks.

'''EDIT:''' Works on Kubuntu 7.10 ("Gutsy Gibbon"), too

===Battery charge control features===
To set the thresholds for starting and stopping battery charging (in percent of current full charge capacity):
:{{cmdroot|echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh}}
:{{cmdroot|echo 70 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh}}
:{{cmdroot|cat /sys/devices/platform/smapi/BAT0/*_charge_thresh}}
{{HINT|Battery charging thresholds can be used to keep Li-Ion ad Li-Polymer batteries partially charged, in order to [[Maintenance#Battery_treatment|increase their lifetime]].}}
To prevent charging for 17 minutes (regardless of thresholds):
:{{cmdroot|echo 17 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes}}
{{HINT|Charge inhibiting can be used to reduce the power draw of the laptop, in order to use an under-spec power supply that can't handle the combined power draw of running and charging. It can also be used to control which battery is charged when [[How to use UltraBay batteries|using an Ultrabay battery]].}}

To cancel charging preventation:
:{{cmdroot|echo 0 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes}}

To force battery discharging (even if connected to AC):
:{{cmdroot|echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge}}
{{HINT|This can be used to choose which battery is discharged when [[How to use UltraBay batteries|using an UltraBay battery]].}}

To cancel forced discharge:
:{{cmdroot|echo 0 > /sys/devices/platform/smapi/BAT0/force_discharge}}

===Battery status features===
To view extended battery status such as charging state, voltage, current, capacity, cycle count and model information:

<pre>
# cat /sys/devices/platform/smapi/BAT0/installed
# cat /sys/devices/platform/smapi/BAT0/state # idle/charging/discharging
# cat /sys/devices/platform/smapi/BAT0/cycle_count
# cat /sys/devices/platform/smapi/BAT0/current_now # instantaneous current
# cat /sys/devices/platform/smapi/BAT0/current_avg # last minute average
# cat /sys/devices/platform/smapi/BAT0/power_now # instantaneous power
# cat /sys/devices/platform/smapi/BAT0/power_avg # last minute average
# cat /sys/devices/platform/smapi/BAT0/last_full_capacity
# cat /sys/devices/platform/smapi/BAT0/remaining_percent
# cat /sys/devices/platform/smapi/BAT0/remaining_running_time
# cat /sys/devices/platform/smapi/BAT0/remaining_charging_time
# cat /sys/devices/platform/smapi/BAT0/remaining_capacity
# cat /sys/devices/platform/smapi/BAT0/design_capacity
# cat /sys/devices/platform/smapi/BAT0/voltage
# cat /sys/devices/platform/smapi/BAT0/design_voltage
# cat /sys/devices/platform/smapi/BAT0/manufacturer
# cat /sys/devices/platform/smapi/BAT0/model
# cat /sys/devices/platform/smapi/BAT0/barcoding
# cat /sys/devices/platform/smapi/BAT0/chemistry
# cat /sys/devices/platform/smapi/BAT0/serial
# cat /sys/devices/platform/smapi/BAT0/manufacture_date
# cat /sys/devices/platform/smapi/BAT0/first_use_date
# cat /sys/devices/platform/smapi/BAT0/temperature # in milli-Celsius
# cat /sys/devices/platform/smapi/ac_connected
</pre>

The raw status data is also available, including some fields not listed above (in case you can figure them out):

:{{cmdroot|cat /sys/devices/platform/smapi/BAT0/dump}}

In all of the above, replace <tt>BAT0</tt> with <tt>BAT1</tt> to address the 2nd battery.

Note that the battery status readout conflicts with the stock [[HDAPS|hdaps]] driver, so if you use <tt>hdaps</tt> you will need to load <tt>tp_smapi</tt> using {{cmdroot|1=make load HDAPS=1}} (see [[#Bundled hdaps driver|Bundled hdaps driver]] below).

On [[ACPI]]-enabled systems, most of above information is also available through the files under {{path|/proc/acpi/battery}}. However, the ACPI interface does not include the instantaneous power and cycle count readouts, and does not work well when [[How to use UltraBay batteries|hotswapping UltraBay batteries]].

====Scripts====
Some scripts can make it easier to grep the information you need from tp_smapi
* [[battery.rb]]

===Other features===

There is also [[sysfs]] attribute for making direct SMAPI requests to the SM BIOS firmware. Don't touch it unless you really know what you're doing. Example:
# echo '211a 100 0 0' > /sys/devices/platform/smapi/smapi_request; cat /sys/devices/platform/smapi/smapi_request
211a 34b b2 0 0 0 'OK'
The "4b" in the 2nd value, converted to decimal, is 75: the current charging stop threshold (stop_charge_thresh).

===Bundled <tt>hdaps</tt> driver===

The tp_smapi package includes a modified version of the <tt>hdaps</tt> Linux kernel driver used by the [[HDAPS]] system. To use <tt>tp_smapi</tt> and <tt>hdaps</tt> concurrently, you '''must''' use the modified version.

To build the modified version, simply append the <tt>HDAPS=1</tt> parameter to the <tt>make</tt> command (see [[#Installation|Installation]] above):
:{{cmdroot|1=make load HDAPS=1}}
or
:{{cmdroot|1=make install HDAPS=1}}

If you don't do that, you will not be able to load <tt>tp_smapi</tt> (and its support module <tt>thinkpad_ec</tt>) when <tt>hdaps</tt> is loaded, and vice versa. You can use <tt>rmmod</tt> to switch between these modules.

Note that some of the battery status is also visible through ACPI ({{path|/proc/acpi/battery/*}}), independently of <tt>tp_smapi</tt>.

The modified <tt>hdaps</tt> has several changes:
* The <tt>hdaps</tt> driver in mainline kernels conflicts with the extended battery status (they use the same IO ports). The modified <tt>hdaps</tt> coordinates this access through the bundled <tt>thinkpad_ec</tt> driver.
* The modified <tt>hdaps</tt> driver fixes reliability and improves support for recent ThinkPad models (*60 and newer), since unlike the mainline driver, it correctly follows the Embedded Controller communication protocol.
* Several other improvements, such as the ability to control the polling rate.

===Troubleshooting===

If you get "<tt>thinkpad_ec: no ThinkPad embedded controller!</tt>" when trying to load the module on a supported model listed below, you should [[BIOS_Upgrade|upgrade your BIOS]]. Some early BIOS (like 1.x on the X31) don't handle the embedded controller.

SMAPI capabilities may depend on the BIOS version as well, so upgrading to the latest version of the BIOS might provide more SMAPI functions (especially true for long-lived BIOS with lots of releases, like the TP-1R).

Please update the above and report your experience on the [[Talk:tp_smapi|discussion]] page. If the module loads but gives a "<tt>not supported</tt>" or "<tt>not implementeded</tt>" error when you try to use some specific file in {{path|/sys/devices/platform/smapi/}}, please report the <tt>dmesg</tt> output and whether the corresponding functionality is available under Windows - maybe your ThinkPad just can't do that.

While at it, you may also want to add your laptop to the [[list of DMI IDs]].

=====HDAPS axis orientation=====
1 The HDAPS axis orientation is set using the <tt>invert</tt> module parameter (at load time) or sysfs attribute (at runtime). The tp_smapi's hdaps driver supports all 8 possible sensor orientations (inversion and swapping). You can use [[HDAPS#Visualisation_of_ThinkPad_orientation|hdaps visualisation]] to check if the settings is correct.

<tt>invert</tt> is an integer between 0 and 7, whose meaning is as follows. Let <tt>X</tt> and <tt>Y</tt> denote the hardware readouts. Let <tt>R</tt> denote the laptop's roll (tilt left/right), and let <tt>P</tt> denote the laptop's pitch (tilt forward/backward). The possible values are as follows:
invert=0: R= X P= Y (same as mainline)
invert=1: R=-X P=-Y (same as mainline)
invert=2: R=-X P= Y (new)
invert=3: R= X P=-Y (new)
invert=4: R= Y P= X (new)
invert=5: R=-Y P=-X (new)
invert=6: R=-Y P= X (new)
invert=7: R= Y P=-X (new)

[[Category:Drivers]] [[Category:Patches]]

===Tools using this driver===

The driver's interface can be accessed directly through the files under {{path|/sys/devices/platform/smapi}}, or via the following tools:
* [[KThinkBat]] - display battery status on the KDE <tt>kicker</tt> panel.
* [[gkrellm-ThinkBat]] - battery status plugin for Gkrellm2
* {{CodeRef|thinkpad-smapi.sh}} - script to display various SMAPI information using tp_smapi module.

This page maintains a database of [http://en.wikipedia.org/wiki/Desktop_Management_Interface DMI] information which can be used to identify ThinkPad models. It is intended as an aid for driver development.
{{HELP|We need more information about older models, especially those released before 2004. Please [[#Adding_entries|add your model]] to the database.}}
{{NOTE|If your ThinkPad is not using the [[BIOS Upgrade Downloads|latest BIOS]], and you would be willing to [[BIOS Upgrade|upgrade your BIOS]], please add your ThinkPad to this table twice: '''before''' and '''after''' the BIOS upgrade. This information helps us a great deal, so your contribution would be very appreciated.}}

==Adding entries==

Click the "Edit" link on the appropriate series above and add an entry of the following form:
:<tt>| </tt>description of your model
:data line 1
:data line 2
:<tt>||</tt>
:<tt>|-</tt>

where the two data lines are generated by the following <tt>bash</tt> command:

<pre>
for X in system-{manufacturer,product-name,version} \
baseboard-{manufacturer,product-name,version} \
chassis-{manufacturer,version} bios-{vendor,version,release-date}; do \
echo -n "|| `sudo /usr/sbin/dmidecode -s $X` "; done; \
sudo /usr/sbin/dmidecode | perl -0777 -ne \
'm/\n(.*).\n.*\n(.*Embedded Cont.*)\n/i; print "\n|| <nowiki><</nowiki>nowiki>$1$2</nowiki>\n"'
</pre>

While at it, you may also want to test [[tp_smapi]] and update its [[tp_smapi#Model-specific_status|model-specific status table]].
