Hi, this series does basically two things: 1. Disables automatic load balancing as adviced by the hardware workaround. 2. Assigns all the CCS slices to one single user engine. The user will then be able to query only one CCS engine I'm using here the "Requires: " tag, but I'm not sure the commit id will be valid, on the other hand, I don't know what commit id I should use. Thanks Tvrtko, Matt and John for your reviews! Andi Changelog ========= v2 -> v3 - Simplified the algorithm for creating the list of the exported uabi engines. (Patch 1) (Thanks, Tvrtko) - Consider the fused engines when creating the uabi engine list (Patch 2) (Thanks, Matt) - Patch 4 now uses a the refactoring from patch 1, in a cleaner outcome. v1 -> v2 - In Patch 1 use the correct workaround number (thanks Matt). - In Patch 2 do not add the extra CCS engines to the exposed UABI engine list and adapt the engine counting accordingly (thanks Tvrtko). - Reword the commit of Patch 2 (thanks John).
