This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.
Main advantages:
============
- vxres > xres support
- ywrap and xpan support
- much faster for almost all modes (e.g. 1280x1024-16bpp
draws more than 41 full screens of text instead of about 25
full screens of text per second on authors Epia 5000)
- module init/exit code fixed
- bugs triggered by console rotation fixed
- lots of minor improvements
- startup modes suitable for high performance scrolling
in all directions
This diff also contains a lot of white space fixes.
No side effects are possible, only one single graphics core is affected.

TODO / Missing features
|
|
=======================
|
|
|
|
Verify LCD stuff "stretch" and "center" options are
|
|
completely untested ... this code needs to be
|
|
verified. As I don't have access to such
|
|
hardware, please contact me if you are
|
|
willing run some tests.
|
|
|
|
Interlaced video modes The reason that interleaved
|
|
modes are disabled is that I do not know
|
|
the meaning of the vertical interlace
|
|
parameter. Also the datasheet mentions a
|
|
bit d8 of a horizontal interlace parameter,
|
|
but nowhere the lower 8 bits. Please help
|
|
if you can.
|
|
|
|
low-res double scan modes Who needs it?
|
|
|
|
accelerated color blitting Who needs it? The console driver does use color
|
|
blitting for nothing but drawing the penguine,
|
|
everything else is done using color expanding
|
|
blitting of 1bpp character bitmaps.
|
|
|
|
ioctls Who needs it?
|
|
|
|
TV-out Will be done later. Use "vga= " at boot time
|
|
to set a suitable video mode.
|
|
|
|
??? Feel free to contact me if you have any
|
|
feature requests
