I have used your patchfile (http://jdelvare.net1.nerim.net/sensors/linux-2.6.11-rc5-i2c-w83627ehf-beta1.diff) to patch my linux-2.6.10 sources (no obvious problems there) and recompiled and installed (I'm running Fedora Core 3). I had hoped that this would give me CPU temperature readings but I didn't get any values when running the sensors command (neither as root nor as normal user, and after running sensors -s): ---------------- # sensors w83627ehf-isa-0290 Adapter: ISA adapter # ---------------- Since then I've read your discussion with David Hoffman and repeated some of the experiments: Initially I could not get the version of sensors_detect at http://www2.lm-sensors.nu/%7Elm78/cvs/lm_sensors2/prog/detect/sensors-detect to detect the W83627EHF at the ISA bus. Here's some of the output: ----------- Do you want to scan the ISA bus? (YES/no): .. Probing for `Winbond W83627EHF' Trying address 0x0290... Failed! .. Do you want to scan for Super I/O sensors? (YES/no): .. Probing for `Winbond W83627EHF Super IO Sensors' Success... found at address 0x0290 Do you want to scan for secondary Super I/O sensors? (YES/no): .. Probing for `Winbond W83627EHF Super IO Sensors' Failed! (skipping family) ----------- After running 'isaset 0x295 0x296 0x4e 0' the W83627EHF is found as an ISA chip as well: ----------- Do you want to scan the ISA bus? (YES/no): .. Probing for `Winbond W83627EHF' Trying address 0x0290... Success! (confidence 8, driver `to-be-written') .. Do you want to scan for Super I/O sensors? (YES/no): .. Probing for `Winbond W83627EHF Super IO Sensors' Success... found at address 0x0290 Do you want to scan for secondary Super I/O sensors? (YES/no): .. Probing for `Winbond W83627EHF Super IO Sensors' Failed! (skipping family) ----------- However, both before and after the isaset command I cannot get any values as output from running sensors. Here is the i2c part of the output from lsmod ------------------------ Module Size Used by .. w83627ehf 18200 0 i2c_sensor 7680 1 w83627ehf i2c_isa 6400 0 i2c_dev 13568 0 i2c_core 24960 4 w83627ehf,i2c_sensor,i2c_isa,i2c_dev .. ------------------------ I've updated modules.conf (actually modprobe.conf on FC3) and lm_sensors as indicated by sensors_detect. Dmesg shows that lm_sensors is loaded without problems (it gave a no sensors found warning before I applied your patches). I have no idea how to debug this further or how to get sensor values but I'm willing to put some time in this as a tester. Were my expectations wrong and can't I use your preliminary driver to get temperature readings? Should I maybe add something to sensors.conf? Are there changes in the 2.6.11-rc5 kernel w.r.t. 2.6.10 that I might need? cheers, -- Leon ------------------------------------------------------------------------ Leon Moonen mailto:Leon.Moonen at computer.org http://www.cwi.nl/~leon/ ------------------------------------------------------------------------ Delft University of Technology | CWI Software Evolution Research Lab | Department of Software Engineering Mekelweg 4, 2628 CD, Delft, NL | Kruislaan 413, 1098 SJ, Amsterdam, NL ------------------------------------------------------------------------
