This package contains all necessary include files and libraries needed
to develop X11 applications that require these.

avrdude is a tool for avr microcontrollers and drives many hardware
in-system programmers. avrdude allows you to program your
microcontroller through the parallel port of your computer.

The glamor module is an open-source 2D graphics common driver for the X Window System as implemented by X.org. It supports a variety of graphics chipsets which have OpenGL/EGL/GBM supports.

It's a GL-based rendering acceleration library for X server:

* It uses GL functions and shader to complete the 2D graphics operations.
* It uses normal texture to represent a drawable pixmap if possible.
* It calls GL functions to render to the texture directly.

It's somehow hardware independently. And could be a building block of any X server's DDX driver:

* Xorg's DDX driver could leverage glamor-egl package to create an egl context without any native X system.Now the xf86-intel-video driver uses glamor as one of its option. When you build it with --enable-glamor, then it will use glamor as its rendering enginee.

This package can support every platform which has OpenGL and gbm and drm libraries.

The package contains the userspace interface to the kernel DRM
services.
