Hello all,
many thanks for your answer.
Modify the X server is a good idea.
I'd just tried to understand the exact place to make changes. Adding many "printf" to understand it.
But it's very complex.
We modified the X Server and swapped when transferring from the shadow
buffer to the video buffer. That cured all our problems.
Could you tell me where is the exact place to do this? in some files like fbdev.c or other?
This was on the 2.4.25 from DENX and with Xfree86.
Sorry but i don't understand this sentence.
Anyway many thanks.

Hello Angelo,
Question to the mailing list readers: is it ok to post an xfree86 or
xorg patch in this mailing list (about 9KiB), or would it be better to
mail that patch to Angelo directly? Thanks.

Sure, if you know where. It took us some time to find "the" correct
place. But see below. :)

The major changes are inside programs/Xserver/miext/shadow/shpacked.c
of either the xorg or xfree86 version of the X server. The swap is
done when copying the data from the shadow buffer to the video memory.
Another place is programs/Xserver/hw/xfree86/drivers/fbdev/fbdev.c,
but here we just setup the Screen correctly, so our new swapping
shadow buffer update route will be used.

We were using Linux 2.4.25 for the PowerPC from DENX and the XFree86 X
Server. The kernel version shouldn't be a problem at all, and I think
the patches should work on either X Server version, Xorg or Xfree86.

I'm interested in it. Please, at least, CC me. :-)
I was having similar issues with my SM501/SM502 on MPC8540/MPC8548.
But due to other projects I had to slow down a bit that area.
Thank you,
Clemens
