The qemu code_gen_buffer is generally between 32MB and 2GB, contiguous. It usually gets AnonHugePage'd. I assume there's no difference in where the hugepages come from on your side? It won't be too difficult to modify qemu to make it's own code generation BTI-safe, and is on the schedule to do eventually anyway. r~ _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
