From 4336073b9b13943e050edfe9aebb99974c3b6ee1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Mon, 17 May 2021 12:51:28 +0200 Subject: cpu: Assert DeviceClass::vmsd is NULL on user emulation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Migration is specific to system emulation. Restrict current DeviceClass::vmsd to sysemu using #ifdef'ry, and assert in cpu_exec_realizefn() that dc->vmsd not set under user emulation.
