> 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!
