Daniele Ceraolo Spurio 9ab28cd20c drm/i915/guc/ct: Stop expecting multiple CT channels ... The GuC supports having multiple CT buffer pairs and we designed our implementation with that in mind. However, the different channels are not processed in parallel within the GuC, so there is very little advantage in having multiple channels (independent locks?), compared to the drawbacks (one channel can starve the other if messages keep being submitted to it). Given this, it is unlikely we'll ever add a second channel and therefore we can simplify our code by removing the flexibility. v2: split substructure grouping to separate patch, improve docs (Michal) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191217012316.13271-3-daniele.ceraolospurio@intel.com		2019-12-17 15:22:47 -08:00
