[Mesa-dev] [PATCH v13 16/36] i965: Remove same-FD restriction for imports

2017-05-19 Thread Daniel Stone
Intel hardware requires that all planes of an image come from the same buffer, which is currently implemented by testing that all FDs are numerically the same. However, when going through a winsys (e.g.) or anything which transits FDs individually, the FDs may be different even if the underlying b
