bit3 of the pci configuration status register
Posted: Sat Sep 03, 2011 6:44 am
In PrettyOS we try to use bit3 of the pci configuration status register for matching the interrupt and the pci device to send to the corresponding device-interrupt-handler. We have noticed that qemu sets this bit3, but VMWare, VBox and some real hardware does not. Hence, we cannot use this great feature. Any comments?
