GLAMOR
GLAMOR is a program library that uses the 3D capabilities of a graphics card to speed up 2D rendering . Glamor is part of the X server from version 1.16 , where it is located as a 2D driver. Glamor is hardware independent and uses OpenGL functions and shaders to display 2D objects.
Glamor has to be implemented by every driver, which has happened so far with radeonsi , nouveau , modesetting and Intel's free graphics driver. However, nouveau has since removed support and instead refers to the modesetting driver.
The goal of Glamor is to replace all previous DDX ( English device dependent X drivers , German device dependent X drivers), i.e. XAA, EXA , UXA and SNA as acceleration libraries.
Glamor can greatly speed up certain operations, but so far EXA is usually a little faster than GLAMOR, which the benchmark GtkPerf shows.
