i2c-core on 2.6.0-test10

i2c-core on 2.6.0-test10

[Anton A. Korzh]

Hello,

i have several question, unabled to find the solution in docs or faq.

I use newwest 2.6 test10 kernel, i have MB based on Apollo 133 chipset,


 i compiled into kernel i2c support, i2c algobit, viapro, i2c_isa,via686a,eeprom.
Also i downloaded 21th november cvs lm_sensors2 and compiled user tools only
The problem is that sensors dont see any sensors on isa bus. As i remeber (and as sensors-detect writes) i need i2c_core to maitain /proc/bus/i2c???
but there are no such directories... 


What should i do in a such situation? 

thank you for any advance,

	Anton.

You probably don't need i2c-algo-bit, but you could compile w83781d in.
I have a board with a KT133 and the via868a chip is not used, instead
there is an as99127f (this is an Asus board) which is handled by the
w83781d driver.

I invite you to update. Significant changes have been made, that could
solve your problems.

/proc is for 2.4 kernels. In 2.6 we use sysfs, usually under /sys.
Make sure you have sysfs support enabled and /sys mounted, and with
up-to-date tools you should get your values back.

Ok, thanks for advice. I've updated just now (28.11.03) lm_sensors2 from cvs, also i upgraded to latest 2.6.0.-test11.
 
i compiled into kernel i2c-dev, i2c-isa,i2c-viapro and all the sensors. Also i have mounted sysfs into /sys and devfs into /devfs.

My mb is Elitegroup P6VEM.


sensors gives me segfault:

sensors-detect now runs ok(earlier it said that i dont have /proc/bus/i2c??? while i got 2.6, but now it seems to be fixed)

What do you think i am doing incorrectly? Do i really need lm80 module(there is no lm80 in 2.6)

thanks, Anton.

Should be fixed in current CVS, if you want to give it a try.
Thanks for reporting.
