exa - new 2D acceleration architecture for X.Org
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 drivers manual page for how to enable
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.
Option 34EXANoComposite34 34boolean34 |
Disables acceleration of the Composite operation, which is at the heart of
the Render extension. Not related to the Composite extension. Default: No.
Option 34EXANoUploadToScreen34 34boolean34 |
Disables acceleration of uploading pixmap data to the framebuffer. Default: No.
Option 34EXANoDownloadFromScreen34 34boolean34 |
Disables acceleration of downloading of pixmap data from the framebuffer.
NOTE: Not usable with drivers which rely on DownloadFromScreen succeeding.
Option 34MigrationHeuristic34 34anystr34 |
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 34always34,
34greedy34, and 34smart34. Default: always.
