[Qemu-devel] [PATCH 5/8] hw/southbridge: Cleanup the PIIX4 chipset in Kconfig

Posted by Philippe Mathieu-Daudé 6 years, 8 months ago

The PIIX4 (Intel 82371AB) is a bridge between PCI <-> ISA.

It is an exhanced PIIX3, thus contains the same features.
It also contains:
 - Power Management (ACPI rev 1.0)
 - IDE UDMA/33
 - SMBus interface (host and slave)
 - RTC
