![]() ![]() The SuperIO chipset (the PIIX4) contains many common devices such as the RTC, PIT, PICs, etc. The main bus of the I440FX is PCI and the SuperIO chipset contains an integrated IDE controller, USB controller, and PCI-ISA bridge. Below is a diagram of what the I440FX architecture looks like: Most platform devices are modelled as ISA devices whereas the ICH9 does not actually have an ISA bus. Email: QEMU support for the PC machine type is fairly poor today.This will allow for better support of PCI-E passthrough since ICH9 uses a PCI-E bus whereas the I440FX only supports a PCI bus. ![]() Add emulation of the ICH9 host chipset as an alternative to the current I440FX emulation. ![]()
