Performance for the two patches:
First patch: 100 fps
second patch: 105 fps (LLC default )
Both patches: 105 fps
But I don't know how to try both patches:
eLLC default
if (level != I915_CACHE_NONE)
- pte |= HSW_WB_ELLC_LLC_AGE0;
+ pte |= HSW_ELLC;
LLC default
if (level != I915_CACHE_NONE)
- pte |= HSW_WB_LLC_AGE0;
+ pte |= HSW_LLC;
Does it mean:
if (level != I915_CACHE_NONE)
- pte |= HSW_WB_ELLC_LLC_AGE0;
+ pte |= HSW_ELLC;
+ pte |= HSW_LLC;</pre>
