[PATCH umr 0/4] gfx9: read VGPRs of halted waves

[Nicolai Hähnle]

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
