I think you left an unresolved CVS conflict at the version numbers. Also had a guy at the unichrome lists that reported a kernel panic within the via modules on a 2.4.20 kernel. I have checked on 2.6.3, and it seems OK. Have you checked 2.4? BTW, Do you think it will be safe from a security point of view to let dri clients still have read access to MMIO registers? /Thomas >> I plan to clean up the unichrome 2D driver with respect to this, but I'm >> not sure when this will happen. >> >> W respect to our previous discussion regarding the Mpeg2 decoder >> I'll try programming it using the 2D commands.
