For the performance test, Jesper has out of tree tests for the page_pool: https://github.com/netoptimizer/prototype-kernel/blob/master/kernel/lib/bench_page_pool_simple.c I have these rebased on top of net-next and use them to verify devmem & memory-provider performance: https://github.com/mina/linux/commit/07fd1c04591395d15d83c07298b4d37f6b56157f My preference here (for the performance part) is to upstream the out-of-tree tests that Jesper (and probably others) are using, rather than adding a new performance test that is not as battle-hardened. -- Thanks, Mina
