Guoyi Tu 0f936247e8 pci: Fix the update of interrupt disable bit in PCI_COMMAND register The PCI_COMMAND register is located at offset 4 within the PCI configuration space and occupies 2 bytes. The interrupt disable bit is at the 10th bit, which corresponds to the byte at offset 5 in the PCI configuration space. In our testing environment, the guest driver may directly updates the byte at offset 5 in the PCI configuration space. The backtrace looks like as following: at hw/pci/pci.c:1442 at hw/virtio/virtio-pci.c:605 val=5, len=1) at hw/pci/pci_host.c:81 In this situation, the range_covers_byte function called by the pci_default_write_config function will return false, resulting in the inability to handle the interrupt disable update event. To fix this issue, we can use the ranges_overlap function instead of range_covers_byte to determine whether the interrupt bit has been updated.
