diego 26b29f4f2d Replace all occurrences of '__volatile__' and '__volatile' by plain 'volatile'. 
We were using an inconsistent mix of the three variants and 'volatile' should
be the most correct and portable variant.

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

                       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.
