bit3 of the pci configuration status register

Post by ehenkes »

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?
