Subject: [PATCH] configure: define CONFIG_XEN when Xen is enabled
Date: Tue, 28 Jul 2020 10:18:28 +0100 [thread overview]
Message-ID: <20200728091828.21702-1-paul@xen.org> (raw)
From: Paul Durrant <pdurrant@amazon.com>
The recent commit da278d58a092 "accel: Move Xen accelerator code under
accel/xen/" introduced a subtle semantic change, making xen_enabled() always
return false unless CONFIG_XEN is defined prior to inclusion of sysemu/xen.h,
which appears to be the normal case. This causes various use-cases of QEMU
with Xen to break.
This patch makes sure that CONFIG_XEN is defined if --enable-xen is passed
to configure.
Fixes: da278d58a092 ("accel: Move Xen accelerator code under accel/xen/")
