Just *partly* answered my own question, from
http://www.archivum.info/linux.debian.ports.arm/2008-01/msg00070.html: "Riku's driver reports actual fan speed rather than tacho value". That's the change from Etch to Lenny. Steve. -------- Original Message --------
Hi, I recently upgraded my N2100 from Etch/arm to Lenny/armel. The fan is now "Supported in in the kernel" according to Martin Michlmayr's status page, but does anyone know how the stuff in sys works, or where I should look to find out? On Etch, the devices were in "/sys/devices/platform/IOP3xx-I2C.0/i2c-0/0-002e". On Lenny, they're at "/sys/devices/platform/IOP3xx-I2C.0/i2c-adapter:i2c-0/0-002e". Also, the fan speed used to be (1,500,000 RPM) / ($sysdev/fan1_input). It seems to be different now. ($sysdev is the path "/sys/devices/platform/IOP3xx-I2C.0/i2c-adapter:i2c-0/0-002e".) I think the stuff at the end of Martin's "installation guide" still seems to relate to Etch. Steve |
