Hi,
I am also having some issues with the CN400 chipset on a VIA EPIA
SP8000E board.
I am using the following software:
* Gentoo Linux
* Kernel 2.6.13 (epia patches from epiawiki.org)
* linux-viafb from DirectFB CVS
* DirectFB-0.9.24 ebuild, unichrome driver
* DirectFB-extra-0.9.23 ebuild
I had to make some trivial changes to be able to patch the kernel using
the linux-viafb patch (Kconfig and Makefile changes). I also added the
PCI device ID (0x3118) of my graphics device to via_fbobj.c (although
I'm not sure it really is supported). I've attached a patch to
linux-viafb showing my changes.
Running the DirectFB examples, everything looks pretty good. df_dok and
df_neo looks ok to me. But when I try to play back video, using e.g.
df_xine, it looks like the wrong colourspace gets used. The image is
stretched to fit the screen vertically, but horizontally it only
occupies the leftmost third of the screen. The rest of the screen
contains garbage. Also the colours are incorrect.
Any ideas? Is this because some features are simply missing from the
unichrome driver, or is it just that the driver doesn't work with the
newer Unichrome devices?
Here's the output of df_xine while playing a DVD:
epia ~ # df_xine dvd://
