[Openchrome-users] CN700 XvMC

[Trevor Kramer]

Hello,

I have successfully gotten X running on a EPIA EN12000E (CN700,  
vt1625) using a patch supplied on the mailing list for tv-out. I also  
built the latest drm code adding the new pci ids the to  
drm_pciids.txt file. Xv works and dri is initialized but when using  
XvMC in mythtv I just a black screen.  This is outputted on the  
system log.

agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0.
agpgart: Xorg tried to set rate=x12. Setting to AGP3 x8 mode.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode
[drm:via_mem_alloc] *ERROR* Attempt to allocate from uninitialized  
memory manager.

here is a snippet from the x log

any idea why the memory allocation is failing?

Thanks,
