[PATCH v3 1/2] qpci_device_enable: Allow for command bits hardwired to 0

2022-09-25 Thread Lev Kujawski
Devices like the PIIX3/4 IDE controller do not support certain modes of operation, such as memory space accesses, and indicate this lack of support by hardwiring the applicable bits to zero. Extend the QEMU PCI device testing framework to accommodate such devices. * tests/qtest/libqos/pci.h: Add
