Page flipping is important. DirectFB uses it a lot. fbdev is almost enough to implement proper page flipping. The only thing missing is getting the current vblank counter from the pan ioctl(). Without that good triple buffering is impossible. And then there is the problem that fbdev doesn't handle overlays so good triple buffering for overlays is impossible right now. That is why I'm quite fond of the "feed the kernel complete register values"-interface. It would work for CRTCs and overlays. Oh and there is no 2D vs. 3D page flipping. -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ------------------------------------------------------- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id%62&alloc_ida84&op=click -- _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
