[Qemu-devel] newer system features ACPI, MSI?

[Qemu-devel] newer system features ACPI, MSI?

[Brad Smith]

I'm looking at QEMU to help develop some device drivers and a couple
of new features would be really useful.  First is bios support for
ACPI so we can run Windows Vista/Longhorn in QEMU.  Second is
PCI Message Signaled Interrupts (MSI) supported in modern Intel
CPUs.  Is there an effort to add these two features to QEMU?
Any patches available?

Hi Brad,

most of the features of the QEMU BIOS came from the BOCHS projects
with some stuff came from Fabrice and others.

You might want to look here:
http://cvs.sourceforge.net/viewcvs.py/bochs/bochs/bios/

I'm not sure that either BOCHS or QEMU ACPI implementation would
satisfy Vista, although I haven't tried installing Vista with Bochs's
latest BIOS.

As for MSI, I don't know if it's implemented in the BIOS, perhaps
Fabrice or Paul can help you with those questions.

Thanks,
Hetz
