[Openchrome-users] CN700 stability

[Christiaan van Dijk]

Hi,

I'm still struggling with the Jetway board. I've got the 1.2GHz fannles 
board with the CN700. The system appeared to be stable but more testing 
showed quite some problems.
Main problem remaining is the handling of concurrent DMA transfers. I 
first blamed the Openchrome driver (for which my apologies :-) ) but the 
real problem is caused by the chipset/initial settings from the BIOS. I 
recently reported the problem to Jetway and got a reply saying they 
would look into it (reply within some days =-O ).
Right now the system is running with only one DMA device enabled (VGA) 
and is stable as far I have tested.

Performance of the machine looks great for a MythTV box, got the XvMC 
and all working just fine, DivX playback gives around 10..15% CPU load. 
Really need the DMA to work for HD+VGA+TV-card, can only wait....

I do not know if the VIA CN700 boards have the same problem with 
concurrent DMA, for the VT8235 there were DMA problems for a very long 
time, a BIOS patch solved  (??)  the problem.
