ANYBODY OUT there to help me? So my Question: I'm trying to rotate the fb by 180°. Reason: I have an embedded board ElanSC400, C&T 65550, etc. I'm reading the driver/video code for a couple of days now, and pinned down myself to three points where I have to do changes to rotate the display. fbcon.c --> fbcon_putc fbcon.c --> fbcon_putcs fbmem.c --> fb_write Is that correct? Kind regards Florian ANYBODY OUT there to help me? |

For the console, I'd just write my own fbcon-*.c replacement (e.g.
fbcon-cfb8-r180.c, cloned from fbcon-cfb8.c) where you take the rotation =
in
mind in the following functions:
- bmove
- clear
- putc
- putcs
- revc
- clear_margins

Thanks a lot for your fast answer!!!
Would you mind sending me your code, cos at the moment my screen is
pretty much screwed up, but not rotated.
I just tried to rotate the *s on putcs. last to first and mirrored every
byte.
Result--> mixed up screen color and chars.
As far as I figured, the *s holds a bunch of bytes for the video_mem.

Yes, the string contains both characters and attributes.
But you don't have to change the fbcon_putcs() routine, you have to chang=
e the
drawing routines in one of fbcon-*.c.

If you end up making any C&T 65550 specific changes, would you mind sendi= ng=20 them to Adrian Cox <ad...@hu...> and myself? We are working on= =20 drivers for the 69XXX chips and I would love to include any rotating code= if=20 I could.

What would be nice if we could give them CVS access to linux-fbdev and they could work out of a common area. > If you end up making any C&T 65550 specific changes, would you mind sending > them to Adrian Cox <ad...@hu...> and myself?

Make sure they have a SourceForge account and the linux-fbdev administrators
can add them to the project.

Yes. Should I make you the other admin, since Brad left?

Dear Mr. Simmons, as far as I know I read the whole docu of the 65550 chip, there was nothing like it. Rotating is on its progress, my vga16 console is allready upsidedown. I sure will mail U any 65550 specificas.
