Talk:SMAPI support for Linux

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.

--lammic, 2005.12.05

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

--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.

--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, 7 Dec 2005

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

--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.

Changing the CD speed when the CD is being accessed will hang your computer

I don't have this problem on my T40p. CDROM is mounted and file on CD is opened. Change speed do not hang my system.

-- Stefan Schmidt

An open file looks fine if you're not reading/writing at that point. But my T43 does hangs on this:

# dd if=/dev/scd0 of=/dev/null &
# echo 1 > /sys/devices/platform/smapi/cdrom_speed

OK, sorry. I was to fast. My system hangs on this commands, too. :(

-- Stefan Schmidt

Works well. Great.

T42 2373-8zh. Working :cdrom_speed and start_charge_thresh. Untest : inhibit_charge_minutes.

-- Haifeng Chen

cdrom_speed works on my T40.

"thinkpad" module kernel compatibility

Ajunge, how do you compile the "thinkpad" module compile on kernel >=2.6.9? The latest thinkpad version (5.8) still uses "get_cpu_ptr" and "set_cpu_ptr", which were removed in 2.6.9.

Feature support matrix

I think it would be a good idea to reflect the supported fetures on each machine in a matrix. The listing is really complex.

--StefanSchmidt

Something like that:

Feature support matrix

×	start_charge_thresh	stop_charge_thresh	inhbit_charge_minutes	cdrom_speed	battery status
G41	working	not working	working	working	unknown
R40	not working	not working	not working	working	unknown
R50p	not working	not working	not working	working	unknown
R51	working	not working	working	unknown	unknown
R52	working	working	working	working	unknown
T40	not working	not working	not working	working	unknown
T40p	not working	not working	not working	working	working
T41	working	not working	working	unknown	unknown
T41p	not working	not working	not working	working	unknown
T42	working	unknown	unknown	working	unknown

X41	working	working	working	unknown	unknown

Good idea. Care to help converting the current data? While at it, we need a new "battery status" column for the new features in tp_smapi 0.09.

--Thinker 01:47, 13 Dec 2005 (CET)

Of course i will help you.

--StefanSchmidt

---

Should we have a "Kernel version" column too?

--Micampe 09:33, 13 Dec 2005 (CET)

I don't think so. There should be no things like: battery_status works with kernel 2.6.13 but not with 2.6.14. If i'am wrong, correct me.

--StefanSchmidt

Beautiful work! I'll move it to the article soon.
