From 6d5322442a6904fef51a409ec40f2945581220d6 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 11 Jan 2016 12:40:28 +0000 Subject: [PATCH] target-sparc: Migrate CWP and PIL for SPARC64 In SPARC32 the env->cwp and env->psrpil state is part of the PSR register, and gets migrated as part of that register. In SPARC64 this state is in separate CWP and PIL registers, but we were not doing anything to migrate those. Add the missing fields to the migration vmstate (which is a migration break, but without these fields migration is completely broken anyway). This change means that trying a save/load of a SPARC64 target at the boot rom prompt now produces a system which at least responds to keyboard input after the restore.
