Hawkins Jiawei 6f34807116 vdpa: Return -EIO if device ack is VIRTIO_NET_ERR in _load_offloads()
According to VirtIO standard, "The class, command and
command-specific-data are set by the driver,
and the device sets the ack byte.
There is little it can do except issue a diagnostic
if ack is not VIRTIO_NET_OK."

Therefore, QEMU should stop sending the queued SVQ commands and
cancel the device startup if the device's ack is not VIRTIO_NET_OK.

Yet the problem is that, vhost_vdpa_net_load_offloads() returns 1 based on
`*s->status != VIRTIO_NET_OK` when the device's ack is VIRTIO_NET_ERR.
As a result, net->nc->info->load() also returns 1, this makes
vhost_net_start_one() incorrectly assume the device state is
successfully loaded by vhost_vdpa_net_load() and return 0, instead of
goto `fail` label to cancel the device startup, as vhost_net_start_one()
only cancels the device startup when net->nc->info->load() returns a
negative value.

This patch fixes this problem by returning -EIO when the device's
ack is not VIRTIO_NET_OK.

Bernhard Beschow c925f40a29 hw/pci/pci: Remove multifunction parameter from pci_new_multifunction()
There is also pci_new() which creates non-multifunction PCI devices.
Accordingly the parameter is always set to true when a multi function PCI
device is to be created.

The reason for the parameter's existence seems to be that it is used in the
internal PCI code as well which is the only location where it gets set to
false. This one usage can be resolved by factoring out an internal helper
function.

Remove this redundant, error-prone parameter.

Bernhard Beschow 752dfff5ec hw/ide/piix: Move registration of VMStateDescription to DeviceClass
The modern, declarative way to set up VM state handling is to assign to
DeviceClass::vmsd attribute.

There shouldn't be any change in behavior since dc->vmsd causes
vmstate_register_with_alias_id() to be called on the instance during
the instance init phase. vmstate_register() was also called during the
instance init phase which forwards to vmstate_register_with_alias_id()
internally. Checking the migration schema before and after this patch confirms:

before:
> qemu-system-x86_64 -S
> qemu > migrate -d exec:cat>before.mig

after:
> qemu-system-x86_64 -S
> qemu > migrate -d exec:cat>after.mig

> analyze-migration.py -d desc -f before.mig > before.json
> analyze-migration.py -d desc -f after.mig > after.json
> diff before.json after.json
-> empty

These instructions used to multiply 2x32-bit GPR sources & accumulate
result into 64-bit pair of XRF registers.

These instructions stain HI/LO registers with the final result.

Their opcode is close to the MIPS32R1 MADD[U]/MSUB[U], so it have to
call decode_opc_special2_legacy when failing to find MXU opcode.
Moreover, it solves issue with reinventing MUL and malfunction
MULU/CLZ/CLO instructions.

Jiaxun Yang 99eff13120 hw/mips/loongson3_virt: Relax CPU restrictions for TCG
After implemented CPUCFG and CSR, we are now able to boot Linux
kernel with Loongson-3A4000 CPU, so there is no point to restrict
CPU type to 3A1000 only, instead we just check for presence of
INSN_LOONGSON3A.

Jiaxun Yang 03afdc28b3 target/mips: Implement Loongson CSR instructions
Loongson introduced CSR instructions since 3A4000, which looks
similar to IOCSR and CPUCFG instructions we seen in LoongArch.

Unfortunately we don't have much document about those instructions,
bit fields of CPUCFG instructions and IOCSR registers can be found
at 3A4000's user manual, while instruction encodings can be found
at arch/mips/include/asm/mach-loongson64/loongson_regs.h from
Linux Kernel.

Our predefined CPUCFG bits are differ from actual 3A4000, since
we can't emulate all CPUCFG features present in 3A4000 for now,
we just enable bits for what we have in TCG.
