Bug description:
QEMU 4.2 introduces new device with this code:
static void build_smb0(Aml *table, I2CBus *smbus, int devnr, int func)
{
Aml *scope = aml_scope("_SB.PCI0");
Aml *dev = aml_device("SMB0");
aml_append(dev, aml_name_decl("_HID", aml_eisaid("APP0005")));
aml_append(dev, aml_name_decl("_ADR", aml_int(devnr << 16 | func)));
build_acpi_ipmi_devices(dev, BUS(smbus), "\\_SB.PCI0.SMB0");
aml_append(scope, dev);
aml_append(table, scope);
}
It is detected by Windows 10 as 'Unknown Device' and there is no driver
available.
Please provide a working Windows driver or give ability to disable this
device.

Hi, although this isn't my area of expertise, the bug caught my eye.
Peter Maydell points out that there is a commit that addresses this
issue:
https://github.com/qemu/qemu/commit/aefcaf9d1b3ebb30981627bd08f595211a648a62
It just never made its way back here to launchpad.

I'm also having this issue on a Win 10 VM running on a unRaid server.

Any progress? When will you provide a Windows driver for this and/or
ability to disable this device in Qemu?

[Bug 1856724] Re: SB.PCI0.SMB0 device drivers unavailable
I noticed this as well. Apparently it was introduced in the following
commit:
https://github.com/qemu/qemu/commit/ebe15582cafeb944a1c6e99aa526e81a1551c567
Saying:
---
pc: Add an SMB0 ACPI device to q35
This is so I2C devices can be found in the ACPI namespace. Currently
that's only IPMI, but devices can be easily added now.
Adding the devices required some PCI information, and the bus itself
to be added to the PCMachineState structure.
Note that this only works on Q35, the ACPI for PIIX4 is not capable
of handling an SMBus device.
