[Qemu-devel] [PATCH v5 1/3] ich9: add TCO interface emulation

2015-06-22 Thread Paulo Alcantara
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not
