From 7e450a8f50ac12fc8f69b6ce555254c84efcf407 Mon Sep 17 00:00:00 2001 From: Jean-Christophe Dubois Date: Wed, 22 Nov 2017 07:32:50 +0100 Subject: target/sparc: remove MemoryRegionSection check code from sparc_cpu_get_phys_page_debug() This code is preventing the MMU debug code from displaying virtual mappings of IO devices (anything that is not located in the RAM). Before this patch, Qemu would output 0xffffffffffffffff (-1) as the physical address corresponding to an IO device virtual address. With this patch the intended physical address is displayed.
