NAME

       rendercheck - simple tests of the X Render extension.

SYNOPSIS

       rendercheck [-d|--display display] [-i|--iter] [--sync] [-t|--tests test1,test2,test3,...] [-o|--ops op1,op2,op3,...]
       [-v|--verbose] [--minimalrendering]

DESCRIPTION

       rendercheck is a set of simple tests of the X Render extension.	It is designed for authors of Render implementations in X Servers.

OPTIONS

       -d|--display display
	      Specifies the display to test against.

       -i|--iter iterations
	      Specifies  the number of times to repeat each operation before sampling results.	Some X Servers may behave differently (hardware vs
	      software rendering paths) depending on the previous operations done, so this may be used to influence the server's choices.

       --sync Enables synchronous xlib operation, for debugging.

       -t|--tests test1,test2,test3...
	      Enables only a specific subset of the possible tests.  Test names include  fill,	dcoords,  scoords,  mcoords,  tscoords,  tmcoords,
	      blend, composite, cacomposite, gradients, repeat, triangles, and bug7366.  Names must be separated by commas and have no spaces.

       -f|--formats format1,format2,format3...
	      Enables  only  a	specific  subset  of the possible formats.  Only formats listed in the server-supported format list are available.
	      Names must be separated by commas and have no spaces.

       -o|--ops
	      Enables only a specific subset of the Render operators.

       -v|--verbose
	      Enables verbose printing of information on tests run, and successes and failures.

       --minimalrendering
	      Disables copying of offscreen destinations to the window, which is on by default to provide the user with visual feedback.

BUGS

       Several	limitations  are  documented  in  the  TODO  file  accompanying  the  source.	Please	report	any  further  bugs  you  find	to
       http://bugs.freedesktop.org/.

NAME

       exa - new 2D acceleration architecture for X.Org

DESCRIPTION

       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 EXA.

       The EXA architecture is designed to make accelerating the Render extension simple and efficient, and results in various performance  trade-
       offs  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 "EXANoComposite" "boolean"
	      Disables acceleration of the Composite operation, which is at the heart of the Render  extension.   Not  related	to  the  Composite
	      extension.  Default: No.

       Option "EXANoUploadToScreen" "boolean"
	      Disables acceleration of uploading pixmap data to the framebuffer. Default: No.

       Option "EXANoDownloadFromScreen" "boolean"
	      Disables acceleration of downloading of pixmap data from the framebuffer.  NOTE: Not usable with drivers which rely on DownloadFrom-
	      Screen succeeding.  Default: No.

       Option "MigrationHeuristic" "anystr"
	      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 "always", "greedy", and "smart".  Default:
	      always.
