This patchset fixes the migration of sPAPR radix guests.
Changes in v1:
--------------
- Added two patches to fix generic savevm unregistration issues.
- HTAB savevm handlers are now registered/unregistered when HTAB
is created/destroyed instead of doing this in CAS call (as in v0).
TODO:
- I have checks in spapr_post_load() to detect and fail the migration
of radix guest to a host that doesn't support radix. However I couldn't
test this as I am hitting some other unrelated migration failure
when testing this path.
- I have tested may scenarios like
- tcg hash->hash, radix->radix, hash->radix and radix->hash reboot
- kvm hash reboot and migration
- kvm radix reboot and migration
However boot->reboot->migration of radix guest doesn't complete
and this seems to be a different issue to be fixed.
v0: https://lists.gnu.org/archive/html/qemu-ppc/2017-05/msg00197.html
Bharata B Rao (6):
migration: Fix unregister_savevm()
migration: Introduce unregister_savevm_live()
spapr: Make h_register_process_table hcall flags global
spapr: Consolidate HPT freeing code into a routine
spapr: Unregister HPT savevm handlers for radix guests
spapr: Fix migration of Radix guests
