From eb9baecdb3aef37ef4952bd4014f14c9d057fa18 Mon Sep 17 00:00:00 2001 From: Sergio Lopez Date: Fri, 4 Mar 2022 11:08:53 +0100 Subject: [PATCH] configure, meson: allow enabling vhost-user on all POSIX systems With the possibility of using a pipe pair via qemu_pipe() as a replacement on operating systems that doesn't support eventfd, vhost-user can also work on all POSIX systems. This change allows enabling vhost-user on all non-Windows platforms and makes libvhost_user (which still depends on eventfd) a linux-only feature.
