That issue is tracked separately in bug 74250.  As for the performance, check
sudo cat /sys/kernel/debug/dri/64/radeon_pm_info and see if the values in there
look sane and if they scale up properly with 3D load.  Report any issues
related to that on bug 74250.

Here's the 3.17 rebased on fixes branch:
