* Some platforms have unusual ways of mapping PCI revision ID to GT/display
|
|
|
|
|
* steppings. E.g., in some cases a higher PCI revision may translate to a
|
|
|
|
|
* lower stepping of the GT and/or display IP. This file provides lookup
|
|
|
|
|
* tables to map the PCI revision into a standard set of stepping values that
|
|
|
|
|
* can be compared numerically.
|
|
|
|
|
*
|
|
|
|
|
* Also note that some revisions/steppings may have been set aside as
|
|
|
|
|
* placeholders but never materialized in real hardware; in those cases there
|
|
|
|
|
* may be jumps in the revision IDs or stepping values in the tables below.
