 |
|
I am in the middle of setting up DirectFB 0.9.17 for use with a Matrox G550.
I am following this howto:
http://www.sci.fi/%7Esyrjala/directfb/matrox-tv-out-howto
and also:
http://www.sci.fi/%7Esyrjala/directfb/Matrox_TV-out_README.txt
both recomend to apply three patches to the linux kernel:
fusion-full-linux-2.4.20.patch.bz2:
Use this patch if you want to run multiple DirectFB apps at the same
time. This is very useful and you should definitely use this one.
matroxfb-32mb.diff.bz2:
Use this patch if you have a 32MB card and you want DirectFB to use
all the memory instead of just 16MB. It won't hurt anything with a
16MB card either.
matroxfb-vsync-c2vline-irq-patch-2.4.19.bz2:
This patch enables IRQ based vblank waiting. Make sure your card has an IRQ assigned to it. You may have an option in the BIOS setup for
this.
These patches seem useful to Matrox and directfb users. And they look harmless to others. I am wondering if they could be added to the default set of kernel patches (for the gentoo kernel?).
By the way, is there a better place to ask this question?

Replying to myself!

Actually, be careful with these two patches. One of them makes my machine hang when I stop the X server!
You have been warned.
Fusion patch is fine, though.

| Have you been able to compile directfb with the "--enable-multi" option? For some reason it complains about not finding the linux/fusion.h file even thou it is there. |

That fusion thing rings a bell! I think I had to copy fusion.h to /usr/include/linux.
