If anyone has any objections, please let me know. ------------------ From: Ben Goz commit e405ca3a1bf166f741506c07c2a277b5d48af8f7 upstream. The current CP firmware can handle Usermode Queues only on MEC1. To reflect this firmware change, this commit reduces number of compute pipelines to 4 - 1, from 8 - 1 (the first pipeline is allocated for kgd).
