In write-only mode, writes are forwarded to RAM, while reads should not be

This patch adds the Vectory Polynomial Multiply Sum instructions
introduced in Power ISA Version 2.07:
- Vectory Polynomial Multiply Sum Byte (vpmsumb)
- Vectory Polynomial Multiply Sum Halfword (vpmsumh)
- Vectory Polynomial Multiply Sum Word (vpmsumw)
- Vectory Polynomial Multiply Sum Do
VHDX test 070 failed, due to different output from qemu-io / qemu
when opening an image read-only that contains a log file. Filter
the output, and update the expected results to match the correct
output.

This patch adds the Vector AES instructions introduced in Power ISA
Version 2.07:
- Vector AES Cipher (vcipher)
- Vector AES Cipher Last (vcipherlast)
- Vector AES Inverse Cipher (vncipher)
- Vector AES Inverse Cipher Last (vncipherlast)
- Vector AES SubBytes (vsbox)
Note that the
VHDX logs can now be replayed via 'qemu-img check -r all'. Add
tests to verify that the log replay is successful when using qemu-img.

If VIRTIO_NET_F_CTRL_VLAN is not negotiated, do not filter out all

Otherwise, return -EIO to disable the quorum and

This VMUL_DO macro provides support for the various vmule* and vmulo*
instructions. These instructions multiply vector elements, producing
products that are one size larger; e.g. vmuleub multiplies unsigned 8-bit
elements and produces a 16 bit unsigned element.
The existing macro works correctly

This patchset enable the core of the quorum mechanism.
The num_children reads are compared to get the majority version and if this
version exist more than threshold time the guest won't see the error at all.
QMP events are used to report individual driver errors or whole quorum

Quorum is a block filter mirroring writes to num_children children.
For reads quorum reads each children and does a vote.
If more than vote_threshold versions are identicals the quorum is reached and
this winning version is returned to the guest. So quorum prevents bit
