From 6773fbf8c07c58429ca876ddea760f604d0497a8 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 30 Jul 2021 11:59:40 +0100 Subject: [PATCH] softmmu: Use accel_find("xen") instead of xen_available() The xen_available() function is used only to produce an error for some Xen-specific command line options in QEMU binaries where Xen support was not compiled in: it just returns the value of the CONFIG_XEN define. Now that accelerators are QOM classes, we can check for "does this binary have Xen compiled in" with accel_find("xen"), and drop the xen_available() function.
