UMA Acceleration Architecture

In computing, UMA Acceleration Architecture (UXA) is the reimplementation of the EXA graphics acceleration architecture of the X.Org Server developed by Intel. Its major difference with EXA is the use of GEM, replacing Translation Table Maps.^[1] In February 2009 it became clear that UXA would not be merged back into EXA.^[2]

The XAA/EXA/UXA/SNA APIs are for the 2D graphics drivers inside the X server. Note, that modern software uses direct rendering.

Intel is transitioning from UXA to SNA.

Implementations

In May 2009 it was announced that Ubuntu would migrate their graphics acceleration for the Ubuntu 9.10 release to UXA.^[3]
