[Qemu-devel] [PATCH 0/4] target-sparc: Update to use VMStateDescription

[Peter Maydell]

This patchset updates target-sparc to use VMStateDescription
rather than hand-written save/load functions. (This and CRIS
are the last two targets still using the old approach.)

It's based on some patches from back in 2012 by Juan which
I've updated, rebased and made some tweaks to.

This is a migration compatibility break; we don't care about
cross-version migration on SPARC guests, and not having to
maintain the old wire format allows a cleaner vmstate
description in several ways.

NB that the 'split cpu_put_psr' patch seems to me to be a
bugfix in and of itself, since currently we might try to
call cpu_check_irqs() and deliver interrupts while we're
halfway through updating a PSR value...

Juan Quintela (2):
  vmstate: introduce CPU_DoubleU arrays
  target-sparc: Convert to VMStateDescription

Peter Maydell (2):
  target-sparc: Split cpu_put_psr into side-effect and no-side-effect
    parts
  target-sparc: Don't flush TLB in cpu_load function
