[PATCH 0/4] dump: Arch info function pointer addition and cleanup

Posted by Janosch Frank 1 year ago

Small cleanups/fixes to the dump info function pointer assignments as
well as a new function pointer for cleanup of residual state.

This has come up because test managed to dump a s390 PV vm onto a disk
that was too small for the dump. After the dump failed, the vm wasn't
able to resume running since KVM was still in dump mode which blocks
vcpu entry.

The new function pointer allows cleanup of such a situation.

Janosch Frank (4):
  dump: Set dump info function pointers to NULL
  target/s390x/dump: Remove unneeded dump info function pointer init
  dump: Add arch cleanup function
  target/s390x/arch_dump: Add arch cleanup function for PV dumps
