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 +.B 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 +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 freamebuffer. 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 \*qEXAOptimizeMigration\*q \*q" boolean \*q +Enables an additional optimization for migration of destination pixmaps. This +may improve performance in some cases (e.g. when switching virtual desktops with +no compositing manager) but causes corruption in others (e.g. when starting +compiz). 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. +.SH AUTHORS +Authors include: Keith Packard, Eric Anholt, Zack Rusin, and Michel D\(:anzer |
