|
|

2007-06-08 00:35:54 +01:00

*
|
|
|
|
* We never break API in for a DRI extension. If we need to change
|
|
|
|
* the way things work in a non-backwards compatible manner, we
|
|
|
|
* introduce a new extension. During a transition period, we can
|
|
|
|
* leave both the old and the new extension in the driver, which
|
|
|
|
* allows us to move to the new interface without having to update the

|
* loader(s) in lock step.
|
|
|
|
*
|
|
|
|
* However, we can add entry points to an extension over time as long
|
|
|
|
* as we don't break the old ones. As we add entry points to an
|
|
|
|
* extension, we increase the version number. The corresponding
|
|
|
|
* #define can be used to guard code that accesses the new entry
|
|
|
|
* points at compile time and the version field in the extension
|
|
|
|
* struct can be used at run-time to determine how to use the
|
