From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> I went ahead and quckly fixed the GPU reset for my 946gz. I had to add a bit of code to restore the display side since that too gets clobbered. I then noticed that according to the specs gen3 should work with the exact same code, so I added the missing bits. g33 is slightly special, but should be close enough. The spec says we should turn off all planes before the reset on g33, but so far I didn't implement that part. Tested with simulated hangs on my 946gz. Would be mildly intersting to see how it fares on other machines, but alas I have none.
