Commen= t # 35 on bug 91278<= /a> from Christian K=C3=B6nig 
The ring and IB are just normal system memory made accessible =
to the GPU. So
it's perfectly fine that it's mapped WC by the CPU.

The processing of the commands written into the ring and IB are triggered by
writing the wptr register.

See radeon_ring_set_wptr().
