[PATCH 0/2] Disable automatic load CCS load balancing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

Changelog
=========
- 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).
