The card now re-inits with

However when power_dpm_force_performance_level is at auto the speeds don't ramp
up

When I was in bioshock everything was at it's lowest levels and I was getting
about 3fps, when I echo'd high into power_dpm_force_performance_level I went
back to 17fps, when I echo'd auto back into power_dpm_force_performance_level
the fps stayed high

When I leave the game and relaunch (so the card is re-initialised with runpm)
it goes back to 3fps  

This is with the latest code in drm-next-4.6-wip - pcie dpm is still disabled

I've done another test

I ran DRI_PRIME=1 glxgears, just to keep the card running

I then launched BioShock and the sclk & mclk again stayed at their lowest
settings, I echo'd high into power_dpm_force_performance_level which changed
the sclk & mclk values. When I echo'd auto back into
power_dpm_force_performance_level and the clocks stayed high. When I exited the
game (with glxgears still running) the clocks went back to their lowest
settings, which is what I'd expect

So it looks like then the card is re-initialized the auto performance level
doesn't work correctly - or is being set to low

Hope this helps

I've just noticed that I don't need to echo "high" then "auto" to get dpm
working, simply echoing "auto" even though that's what it's set to is enough to
get the FPS to jump back up to a playable rate
