+.SH NAME
+exa \- new 2D acceleration architecture for X.Org
+.SH DESCRIPTION
+.B EXA
+provides a simple API for video drivers to implement for 2D acceleration.
+It is a module loaded by drivers,
+and is not intended to be loaded on its own.
+See your driver's manual page for how to enable
+.BR EXA .
+.PP
+The
+.B EXA
+architecture is designed to make accelerating the Render extension simple
+and efficient,
+and results in various performance tradeoffs compared to XAA.
+Some xorg.conf options are available for debugging performance issues
+or driver rendering problems.
+They are not intended for general use.
+.TP
+.BI "Option \*qEXANoComposite\*q \*q" boolean \*q
+Disables acceleration of the Composite operation,
+which is at the heart of the Render extension.
+Not related to the Composite extension.
+Default: No.
+.TP
+.BI "Option \*qEXANoUploadToScreen\*q \*q" boolean \*q
+Disables acceleration of uploading pixmap data to the framebuffer.
+Default: No.
+.TP
+.BI "Option \*qEXANoDownloadFromScreen\*q \*q" boolean \*q
+Disables acceleration of downloading of pixmap data from the framebuffer.
+.B NOTE:
+Not usable with drivers which rely on DownloadFromScreen succeeding.
+Default: No.
+.TP
+.BI "Option \*qMigrationHeuristic\*q \*q" anystr \*q
+Chooses an alternate pixmap migration heuristic,
+for debugging purposes.
+The default is intended to be the best performing one for general use,
+though others may help with specific use cases.
+Available options include \*qalways\*q,
+\*qgreedy\*q,
+and \*qsmart\*q.
+Default: always.
