So, AFAIU acpi_get_pci_dev will give me pointer to struct pci_dev of video card, yes?
There is some path I could use then:
struct pci_dev { ..... struct pci_driver *driver; /* which driver has allocated this device */ ..... }
struct pci_driver { ..... struct device_driver driver; ..... }
Finally, struct device_driver is defined in device.h. Should I add flag bool is_kms to this struct then?
AFAIK we can not do anything with struct driver_private *p... Or is there unified struct for video card drivers? We could then add flag is_kms to some struct pointed by struct driver_private *p.
