Hi, Oleg. Do you require dumps for PITCAIRN chips

Yes, I need as much dumps as possible. I hope overdrive v6 works for all SI chips, so I've made simple example program for testing >SI asics, it lays here https://github.com/Adonai/radeon-fancontrol. You can check if it works while in X session with fglrx driver.

So you should do the following:

1) install fglrx and configure it 2) switch to text console and stop any X being used 3) rmmod fglrx 4) now start mmiotrace (kernel has pretty nice doc here https://www.kernel.org/doc/Documentation/trace/mmiotrace.txt) 5) modprobe fglrx 6) start X && export DISPLAY=:0 7) now begin to collect data from mmiotrace (via cat trace_pipe &), you can put some marks here 8) start above mentioned program. There should be some noize from GPU fan for 6 seconds, it's normal 9) after it exits (in 10 seconds) collect its output and piped mmiotrace logs and post the results here

Thanks!
