README.Matrox 

The code in this directory is the old mga_vid driver for Linux kernels
prior to 2.6. It does _not_ compile for version 2.6.x.

For Linux kernel 2.6.x please get the newest version of the 2.6 port from

mga_vid  -  MGA G200/G400 YUV Overlay kernel module

                       WARNING  -----  WARNING

This code messes with your video card and your X server. It will probably
lock up your box, format your hard drive, and cause your brand new G400
MAX to spout 6 inch flames. You have been warned.

                       WARNING  -----  WARNING

What does this code do?

	 mga_vid is a kernel module that utilitizes the Matrox G200/G400/G550
	 video scaler/overlay unit to perform YUV->RGB colorspace conversion
	 and arbitrary video scaling.

	 mga_vid is also a monster hack.

How does mga_vid work?

	This kernel module sets up the BES (backend scaler) with appropriate
	values based on parameters supplied via ioctl. It also maps a chunk of
	video memory into userspace via mmap. This memory is stolen from X
	(which may decide to write to it later). The application can then write
	image data directly to the framebuffer (if it knows the right padding,
	etc).


How do I know if mga_vid works on my system?

	There is a test application called mga_vid_test. This test code should
	draw some nice 256x256 images for you if all is working well.
