From 11ed09cf0753c1288a97f00138fc4534135442bb Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Wed, 29 May 2013 21:54:03 +0200 Subject: [PATCH] memory_mapping: Improve qemu_get_guest_memory_mapping() error reporting MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Pass any Error out into dump_init() and have it actually stop on errors. Whether it is unsupported on a certain CPU can be checked by looking for a NULL CPUClass::get_memory_mapping field.
