tp_smapi fails on boot in thinkpad EDGE 13

[tasty-minerals]

tp_smapi gets screwed in Arch on thinkpad EDGE 13. How to fix it?

System: Linux archbang 3.0-ARCH #1 SMP PREEMPT Wed Aug 17 21:55:57 CEST 2011 x86_64 AMD Turion(tm) Neo X2 Dual Core Processor L625 AuthenticAMD GNU/Linux

modprobe tp_smapi
FATAL: Error inserting tp_smapi (/lib/modules/3.0-ARCH/extra/tp_smapi.ko): No such device or address

dmesg | grep thinkpad_ec

tp_smapi version 0.41
more info see forum page please (https://bbs.archlinux.org/viewtopic.php?pid=984015#p984015)
Actually tp_smapi has never worked on any kernel release for EDGE

Well, it can't find the EC, so no luck for you here at the moment.
I have heard that the latest bios helps on some Edges, (like the Edge 01962DG).
However, hdaps seems not to work on them either, only some battery functions.
Could you also try https://gitorious.org/linux-test-utils/tp_charge (when gitorious is back online again) and tell me whether it works for you?

[teleshoes]

yea, lenovo hates us, and likes destroying batteries. they dont announce the EC on some newer devices {e.g. w520}, and on others, dont expose it at all. i believe youre out of luck with the EDGE.

the default behaviours are always the exact wrong ones, too.

evgeni, tp_charge appears to work with my w520, but wont of course allow me to switch discharging battery.

[evgeni]

@teleshoes tp_smapi 0.41 does work on the w520 too? i only had chance to test it on x220 and t420 :)

[teleshoes]

yep- the only thing 0.40 is missing to make w520 work is
TP_DMI_MATCH("LENOVO", "ThinkPad"),
because the EC isnt announced properly. {probably intentional, since they broke force_discharge and dont want to encourage backwards compatibility}

btw, im thinking of having my easy-install script install from your repo. that ok with you?

[evgeni]

bah, stupid keyboard shortcuts, didnt mean to close...

yeah, the dmi match is the very thing I did in .41
and you are ofcourse free to use the repo in your scripts, just don't cry if I break master in the future ;) (hint: use tags)

@evgeni You said you tested it on T420. I'm trying to install tp_smapi 0.40 on my T420 running Fedora 17 but I'm without any success. I'm getting this error:

Error: could not insert module ./thinkpad_ec.ko: No such device

and after some dmesg output, in the end:

[ 3562.288485] thinkpad_ec: no ThinkPad embedded controller!

Can you help me with this?

[evgeni]

@eduardowoj I only very shortly tested it on the t420 as I do not own a T420 and am pretty sure that tp-smapi 0.40 will fail there as it does on X220 etc. Try 0.41 (or 280da64), but do not expect much magic. It should load and some functions might work. That's it.

[eduardowoj]

@evgeni Oh, sorry. But thanks anyway, I'll try the 0.41 :-)

[hit]

Although it should load on ALL thinkpads after 280da64, it won't on Edge E325.

Do you have a log what it is complaining about?
And, even if it would load, I bet it would not work on an E325, but let's start with a log.

Something more or is this enough?

[evgeni]

Enough to tell you your model is unsupported. Nothing you wanted to hear maybe, but the truth :)

Excactly what I suspected... :|
