Introduce a dummy AST2600 I3C model.
Aspeed 2600 SDK enables I3C support by default. The I3C driver will try
to reset the device controller and setup through device address table
register. This dummy model response these register with default value
listed on ast2600v10 datasheet chapter 54.2.
While using SCSI passthrough, Following scenario makes qemu doesn't
realized the capacity change of remote scsi target:
1. online resize the scsi target.
2. issue 'rescan-scsi-bus.sh -s ...' in host.
3. issue 'rescan-scsi-bus.sh -s ...' in vm.
In above scenario I used to experienced errors while

This series adds both riscv32 and riscv64 kvm support, and implements
migration based on riscv.
Because of RISC-V KVM has been merged into the Linux master, so this
series are changed from RFC to patch.
Several steps to use this:
1. Build emulation
$ ./configure --target-list=riscv64-softmmu
$

Although "<< 2" has the same effect as "* 4" here, isn't "<< 2" better in matching the

Yes, good point.

Aren't we capable of page sizes up to 64KiB? Minimal feasible page size is indeed 16KiB
though (due to cache aliasing, although 4KiB pages are supported in hardware, they don't
work in practice).
You must use the minimal page

Fixes a couple of issues with irqfd use by config interrupt:
- Rearrange initialization so cleanup happens in the reverse order
- Don't use irqfd for config when not in use for data path

Few patches to be able to build QEMU on macOS 12 (Monterey).
This basically consists of adapting deprecated APIs. I am not
sure about these APIs, so tagging as RFC.
I couldn't succeed to adapt the Cocoa code.
CI job added to avoid bitrotting (ignoring the Objective C
deprecation warning).
