From 593a1cdd66ac83c1cefdd4cc5dd6338006fc202c Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Mon, 9 Jul 2018 19:02:36 +0200 Subject: [PATCH] sm501: Update screen on frame buffer address change When the guest changes the address of the frame buffer we need to refresh the screen to correctly display the new content.
