[Xorg] Xfbdev acceleration.

[Michael Frey]

Hello,


I have been using Xfbdev from the XFree86 branch for some time.  I 
added acceleration code to fbdev for an Epson chip I am using.  It 
works great.
I want to move to the freedesktop.org Xfbdev server and I am having 
trouble moving my blt code over.  I noticed that the new server uses 
offscreen pixmaps for acceleration.

My video card does not have enough memory for offscreen pixmaps and 
only has enough memory for the on-screen frame buffer.  If I fill out 
in fbinit.c my functions for acceleration they never get called because 
in fbdev.c
     screen->memory_size = 0;
     screen->off_screen_base = 0;

I tried changing the memory setting to be the memory size of my board 
but with no luck.

Is there a way to enable acceleration without using offscreen pixmaps 
the way the old kdrive used to do it?

Thanks in advance,
Michael Frey
