[Qemu-devel] [PATCH v2 0/8] target-sparc: Update to use VMStateDescription

[Peter Maydell]

This patchset updates target-sparc to use VMStateDescription
rather than hand-written save/load functions. (SPARC is the
very last target still using the old approach. Once this patchset
gets in via the sparc tree I'll send out the patches to clean
up the core QOM CPU code to remove the unused support for
hand-written save/load.)

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

The major change here from v1 (sent back in August last year)
is that we retain migration format compatibility for SPARC32.
SPARC64 compat is broken, but SPARC64 migration doesn't work
at the moment for any of our machines so that's OK.

Also new since v1 is the final patch, which fixes a bug spotted
by Paolo where we weren't migrating env->cwp or env->psrpil for
SPARC64. This bug fix means that sparc64 migration of a system
that's sat at the boot prompt now works at least to the extent
that the system will respond to key presses after the restore.

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 (4):
  vmstate: introduce CPU_DoubleU arrays
  vmstate: Introduce VMSTATE_VARRAY_MULTPLY
  vmstate: define vmstate_info_uinttl
  target-sparc: Convert to VMStateDescription

Peter Maydell (4):
  target-sparc: Split cpu_put_psr into side-effect and no-side-effect
    parts
  target-sparc: Don't flush TLB in cpu_load function
  target-sparc: Use VMState arrays for SPARC64 TLB/MMU state
  target-sparc: Migrate CWP and PIL for SPARC64
