New applesmc module for all models - Call for testing

[kosumi68]

@henrik - thanks for this, I know we discussed it a while back and I never got the time to look at implementing something like this myself - thanks again for your hard work, will have a look at it in the next few days. Any chance of trying to merge this is 2.6.37?

Hi Alex,

Too late for 2.6.37, but we are targeting 2.6.38.

Cheers!

No worries - at least it should make it into Natty then automatically. Thanks again for your great work Henrik! You're awesome!

So macfanctld throttles up to max fan speed. Needed to adjust the /etc/macfanctl.conf to low down the fans, i.e. I added

exclude: 1 2 3 4

Hi Nikos,

Thanks for the report! Did you get similar errors with the old module? It appears the failures are frequent but still random. Does it work sometimes, or failure each time? Did the values of TB0T etc have different values with the old module?

[Nikos.Alexandris]

Hi!

Did you get similar errors with the old module?

As far as I remember, never.

It appears the failures are frequent but still random. Does it work sometimes, or failure each time?

Till now, as many times as I have checked dmesg I always read lots of read/write arg fail.

Did the values of TB0T etc have different values with the old module?

I think yes, i.e., I work mostly with the battery dettached (the last years) and the fans are at full-speed since last week(s).

Cheers

[kosumi68]

As far as I remember, never.

Trying to frame this problem further, did you by any chance start using macfanctld at around that time too? What happens (in dmesg) if you perform these commands manually? Unless you already did,

sudo -i
cd /sys/devices/platform/applesmc.768/
cat fan2_manual
cat fan2_min
echo 4000 > fan2_input
cat fan2_min
echo your_default_value > fan2_input
cat fan2_min

Thanks!

Till now, as many times as I have checked dmesg I always read lots of read/write arg fail.

To make this more clear, I mean "till now = since last week(s) with the new applesmc". Sorry for not being precise.

I started using macfanctld in the summer (...dunno when exactly, August?). The thing with the above commands is the following (me thinks):

-r--r--r-- 1 root root 4096 2010-11-22 22:52 fan1_input
-r--r--r-- 1 root root 4096 2010-11-22 22:52 fan2_input

Those input files are read-only! Otherwise, the fan2_manual is always 0 and fan2_min changes. Should I change owner permissions?

Yes, fanX_manual, fanX_min and fanX_output should all be read-write. This is odd, they should definitely appear as rw, unless you changed them. A

sudo rmmod applesmc; sudo modprobe applesmc

should yield rw permissions on those files.
