imsolidstate Posted August 25, 2013 Share Posted August 25, 2013 I've been searching for something to get fan control working on my 6990m GPUs in linux. They are stuck at whatever speed was set during boot by the BIOS. HWinfo64 works great for Windows, but is there something similar for linux?Setting aticonfig --pplib-cmd has no effect. It reports success but has no effect on the fans. Reading the temps seems to work ok with aticonfig --adapter=all --odgt.Since HWinfo64 can make it work on Windows, I'm pretty sure it's an issue with the drivers writing to the wrong registers. I wondered if anyone knew something about this.I know most of the temps are pulled from the SMbus, but I don't know if the GPU sensors are available on the SMbus. I think I might start looking for an SMbus/I2C library and dump the SMbus traffic with a C program. Otherwise I would have to take the laptop apart and get hardware access to the bus with a logic analyzer, which I don't really want to do. Does anyone know more about this? Thanks.
