I noticed whilst testing the previous dp8393x patchset that I would always get a segfault whilst attempting to migrate the MIPS magnum machine.
A bit of detective work shows that the problem is an incorrect VMStateDescription in the g364fb device which expects a G364State but instead receives a G364SysBusState. Looking back through the git history suggests that migration for this device (and also the MIPS magnum machines) has been broken for several years, so patch 1 takes the opportunity to improve the migration stream for the framebuffer first whilst patch 2 contains the actual fix. Note that I don't use the MIPS magnum machines on a regular basis but the patchset fixes the migration error and survives some light testing here. Signed-off-by: Mark Cave-Ayland <mark.cave-ayl...@ilande.co.uk> v2: - Bump migration version to 2 as suggested by Phil (note: I've done this in both patch 1 and patch 2 to keep the versions identical) - Remove unused vram pointer from G364State in patch 1 - Added R-B tag from Phil Mark Cave-Ayland (2): g364fb: use RAM memory region for framebuffer g364fb: add VMStateDescription for G364SysBusState hw/display/g364fb.c | 32 ++++++++++++++++++++------------ 1 file changed, 20 insertions(+), 12 deletions(-) -- 2.20.1
