Loongson Binary Translation (LBT) is used to accelerate binary

Here lbt=on/off property is added to parse command line to

Six registers scr0 - scr3, eflags and ftop are added in percpu vmstate.
And two functions kvm_loongarch_get_lbt/kvm_loongarch_put_lbt are added

The vfio-user container will later need to hook into these callbacks;
set up vfio to use them, and optionally pass them through to the
container.

This patch introduces the vfio-user protocol specification (formerly
known as VFIO-over-socket), which is designed to allow devices to be
emulated outside QEMU, in a separate process. vfio-user reuses the
existing VFIO defines, structs and concepts.

Hello,
This is the 6th revision of the vfio-user client implementation.
First of all, thank you for your time reviewing the previous versions.
The vfio-user framework consists of 3 parts:
1) The VFIO user protocol specification.
2) A client - the VFIO device in QEMU that encapsulates VFIO mess

There are a few more bits referencing centos8 in the tree which needed
cleaning up. After this we can remove the dedicated runner from the
gitlab registration. If we want to keep a dedicated Centos runner then
we can add back the bits needed to set it up.
I plan to generate the PR on Friday.

As Centos Stream 8 goes out of support we need to update. To do this
powertools is replaced by crb and we don't over specify the python3 we
want.

This broke since eef0bae3a7 (migration: Remove block migration) but
even after that was addressed it still fails to complete. As it will
shortly be EOL lets to remove the runner definition and the related
ansible setup bits.
We still have centos9 docker images build and test.
