- This directory contains an analogue of "mfb" for memory color framebuffers.
- It can be configured to support a number of different devices:
-
- - They must be organised as packed pixels, not planewise.
- - They must have fewer than 32 bits per pixel.
-
- The code has been tested only on displays with a pixel size of 8 bits,
- both with all 8 planes implemented (Sun) and less than 8 planes implemented (HP).
- As distributed, it is set up for 8-bit pixels with all 8 planes implemented.
- If your display is different, see maskbits.h.
-
- The code is intended to be highly portable, and to use as much as possible of the
- "mi" code. As a result, it is very slow. But we believe it should be very
- easy to port. We believe that the code only ever accesses the framebuffer 32 bits
- wide at 4-byte aligned addresses.
-
- As delivered, the code supports a PseudoColor visual. By defining STATIC_COLOR,
- you can configure it (and the .../sun directory) to support a StaticColor visual
- instead. This has proved useful in testing the server.
