Add Loongson-3 based machine support, it use liointc as the interrupt

MIPS has two types of KVM: TE & VZ, and TE is the default type. Now,
libvirt uses a null-machine to detect the kvm capability. In the MIPS

So, add the kvm_type() hook to the null-machine.
This seems not a very good solution, but

Greetings,
The final report of the TCG Continuous Benchmarking series introduces
basic performance measurements for QEMU system mode emulation.
The latest version of Debian 15.0 is used for testing and comparing
the emulation performance on five targets (aarch64, arm, mips, mipsel,
and x86_64).

I am able to hit this assertion when a Red Hat 7 guest virtio_net device
raises an "Invalidation" of all the TLB entries. This happens in the
guest's startup if 'intel_iommu=on' argument is passed to the guest
kernel and right IOMMU/ATS devices are declared in qemu's command line.
Command line:
/h
Previous name didn't reflect the iommu operation.

This improves performance in case of netperf with vhost-net:
* TCP_STREAM: From 1374.81Mbit/s to 1845Mbit/s (37%)
* TCP_RR: From 6559.36 trans/s to 7916.29/s (21%)
* UDP_RR: From 6705.39 trans/s to 8199.39/s (22%)
* UDP_STREAM: No change observed (not significant 0.1% improvement)

It will allow firmware to notify QEMU that firmware requires SMI
being triggered on CPU hot[un]plug, so that it would be able to account
for hotplugged CPU and relocate it to new SMM base and/or safely remove
CPU on unplug.
Using negotiated features, follow up patches will insert SMI upcall

Due to the commit 65da4539803373ec4eec97ffc49ee90083e56efd, the O_DIRECT
open flag of guest applications will be discarded by virtiofsd. While
this behavior makes it consistent with the virtio-9p scheme when guest
applications use direct I/O, we no longer have any chance to bypass the

This patch adds the U2F key emulated mode.
The emulated mode consists of completely emulating the behavior of a
U2F device through software part. Libu2f-emu is used for that.
The emulated mode is associated with a device inheriting from
u2f-key base.
To work, an emulated U2F device must have dif
This patch series adds the U2F dedicated support to Qemu through a USB
U2F key device that can operate in two modes: pass-through and emulated.
This work is also part of the GSoC program of this year and follows the
