In order to reduce the cost of TLB invalidation, the ARMv8.4 TTL feature allows TLBs to be issued with a level allowing for quicker invalidation. This series provide support for this feature. Patch 1 and Patch 2 was provided by Marc on his NV series[1] patches, which detect the TTL feature and add __tlbi_level interface.
I realy hate how it makes vma->vm_flags more important for tlbi. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
