From 843caef2ef1fd524de66a035b88a9153350ad392 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Fri, 18 Jan 2019 17:18:48 +0000 Subject: [PATCH] target/s390x: define TCG_GUEST_DEFAULT_MO for MTTCG MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MTTCG should be enabled by default whenever the memory model allows it. s390x was missing its definition of TCG_GUEST_DEFAULT_MO meaning the user had to manually specify --accel tcg,thread=multi.
