Hi all,
On ARM hardware, as qemu docs describes, "Named CPU models generally

We must not inactivate child when parent has write permissions on

Calling .bdrv_inactivate() doesn't help: actually only qcow2 has this

I am referring to the latter,"purely emulated QEMU with an emulated
SMMU that handles accesses to emulated devices"

In mirror_iteration() we call mirror_wait_on_conflicts() with
`self` parameter set to NULL.
Starting from commit d44dae1a7c we dereference `self` pointer in
mirror_wait_on_conflicts() without checks if it is not NULL.

Surely there is no "o32" for loongarch?
Yes, qemu only support 64bit. but the kernel has 'o32'. Shoul

In that case, the stage 2 tables are set up by the guest
