Subject: pci_id_driver_map: Support preferring iris over i965
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cfbde3282d9b881a8cb09dc7a9c2b25b69872e32;p=mesa.git

pci_id_driver_map: Support preferring iris over i965

This adds the ability for intel devices that:

 * Only load on i965
 * Only load on iris
 * First attempt i965, and try iris next
 * First attempt iris, and try i965 next
