[Qemu-devel] [PATCH 0/2] mips boston/malta: don't have nomigrate RAM regions

[Peter Maydell]

This patchset fixes a a bug in the MIPS boston and malta boards:
they currently use memory_region_init_rom_nomigrate() to create
memory regions for their BIOS/flash, and they don't manually
register the MR with vmstate_register_ram() either. This currently
means that its contents are migrated, but as a RAM block whose
name is the empty string; in future (when a patch which is currently
in the outstanding migration tree pull request hits master) it
will mean they are not migrated at all. Switch to using
memory_region_init_ram() instead, so the memory contents are
migrated with a reasonable name.

Note that this is a cross-version migration compatibility break
for both machines, but:
 (a) migration will break anyway due to the "don't migrate
     unnamed RAM blocks" patch
 (b) neither machine is versioned, so we don't really care about
     maintaining cross-version migration compatibility AFAIK

thanks
