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 220.127.116.11.

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).
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.
-- 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.

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
--Thinker 16:41, 7 Dec 2005 (CET)
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.
--Thinker 13:53, 10 Dec 2005 (CET)
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 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. :)
