The Last Level Cache is split into many slices, each one of which can be toggled on or off.
Only certain slices are recommended to be turned on unconditionally, in order to reach optimal performance/latency/power levels.
Enable WRCACHE on X1 at boot, in accordance with internal recommendations.
Thanks for the update. Can you say something about what WRCACHE is used for as well?
No significant performance difference is expected.
This matches my findings (and it seems the slice has not been left enabled by the boot firmware).
