From a7f981cc9f3e5a99c6690c144ba1d6a77394c39b Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 5 Oct 2017 15:50:48 +0200 Subject: [PATCH] moxie: fix qemu-system-moxie failing to start with CLI "-cpu MoxieLite" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It 'works' with default CPU only because of bug in moxie_cpu_class_by_name() where it treats cpu_model as type name and default cpu_model also happens to be type name. But specifying explicitly cpu on CLI, ex: '-cpu MoxieLite', makes QEMU fail since moxie_cpu_class_by_name() doesn't traslate cpu_model to cpu type and fails to find corresponding object class. Fix moxie_cpu_class_by_name() to do proper cpu_model -> cpu type translation and fix default cpu_model to be cpu_model instead of being typename.
