Agpgart
From Free net encyclopedia
AGPgart is a kernel module for Linux and Solaris supporting the extra data transfer features of AGP video cards.
The AGPgart driver is a kernel module that uses system memory to enhance graphics display. This feature is useful for memoryless graphics devices such as Intel integrated graphics and AGP graphics, which need to use system memory as video buffers.
Desktop users who use Intel 810/830/855 series graphics devices can achieve higher resolution of screen images under Xorg xserver with only 1 megabyte of BIOS-allocated video RAM. Video driver developers can utilize the AGPgart driver to allocate system memory for 2-D display or 3-D display and to manage AGP devices.
For more information, see the agpgart_io(7i) man page in Solaris Release sol-nv-b17 or later.
History
Jeff Hartmann was the primary maintainer of agpgart, which began life as part of the utah-glx accelerated MesaGL driver project by Brian Paul. It was primarily targetted at the Linux 2.4 kernel series, but patches were made available against older 2.2 kernels. Dave Jones from SuSE Labs heavily reworked agpgart for the Linux 2.6 kernel series along with more contributions from Jeff Hartmann.Template:Ref
