Hi Nicolai,
Patches look good I'll give them a whirl tomorrow when I have some free
time. I'll have to dig out your headless piglit instructions since I
still can't bring X up on my Raven board.
Also I noticed the use of "(options.bitfields)" (etc, in print_waves)
which is not your bug (since I did it first hehehe) but is a bug ...
they should all be "asic->options.bitfields" which I'll fix in a
follow-up patch after.
(provided they apply and combined with the kernel patch doesn't oops on
me I'll R-b + push them out tomorrow or Monday morning).
Thanks,
Tom

Hi all,
it seems that reading wave VGPRs actually works now with gfx9, at least
for halted waves, and that can be pretty powerful for debugging.
Due to the volume of data it prints out, it's only enabled with -O bits.
In order for it to work properly, you'll also need the kernel patch
I just sent out (drm/amdgpu/gfx9: implement wave VGPR reading).
Please review!
Thanks,
Nicolai
