I hope you caught the changes in the updates, there was one potentially
important one with synchronizing gen6_[en|dis]able_rps().

Also, I've pushed my updated tools (which is just read and write for
now) to here:
git://anongit.freedesktop.org/~bwidawsk/intel-gpu-tools
branch: good_reg

When/if you do the announce for staging, I will reply there as well with
this repo, and push it once the kernel changes stick.

Thanks.
