Under some conditions (documented in this patch), the UploadToScreen
implementation can make use of the AGP scratch buffer used for XVideo as
a convenient source for Mastered Image Transfer. The previous
implementation is still available as a fallback for when AGP
acceleration is not possible. This requires the AGP scratch buffer to be
persistent, so the XVideo code is also made aware of an existing DRM
mapping for the scratch buffer.
perl -e '$x=2.3;printf("%.0f + %.0f = %.0f\n",$x,$x,$x+$x);'
