passt/test/perf/passt_vu_udp, branch bug165b Plug A Simple Socket Transport test: Add tests for passt in vhost-user mode 2024-11-27T15:49:21+00:00 Stefano Brivio sbrivio@redhat.com 2024-11-22T16:43:35+00:00 676bf5488ec4bd4312dbae4be1a1bb2ed02bd2ba Run functional and performance tests for vhost-user mode as well. For functional tests, we add passt_vu and passt_vu_in_ns as symbolic links to their non-vhost-user counterparts, as no differences are intended but we want to distinguish them in test logs. For performance tests, instead, we add separate perf/passt_vu_tcp and perf/passt_vu_udp files, as we need longer test duration, as well as higher UDP sending bandwidths and larger TCP windows, to actually get the highest throughput vhost-user mode offers. For valgrind tests, vhost-user mode needs two extra system calls: statx and readlink. Add them as EXTRA_SYSCALLS for the valgrind target.
