It provides userspace +video drivers (Matrox, Ati, 3Dlabs, Trident). + +For the full list of supported OS'es read the sources, but here's a reported +as working list (these platforms are used daily): + Linux/x86 + FreeBSD/x86 + NetBSD/x86 + Linux/PPC + +There are different ways to access the hardware, normally only ROOT can do that. +With root privileges libdha will finely run, but there are some others ways +to use it as a normal user: +1, set the SUID bit on the binary (in this was it runs with root priviliges) +2, use svgalib kernel helper +3, use dhahelper (not yet finished) + +The library is based on XFree86 and gfxdump (a utility from GATOS project) +sources. + +Original import and design by Nick Kurshev and Alex Beregszaszi. +Current maintenance and dhahelper by Alex Beregszaszi. +Svgalib kernelhelper support by Matan Ziv-Av. +(for the e-mail addresses see the AUTHORS file in MPlayer)
