* nVidia acceleration. The obfuscated fbdev or XFree86 driver code could be stolen and adapted for kdrive. * General mode-setting framework with backends for vesa, fbdev, and native mode setting where available. * DRI integration. This will allow drivers to use the DRM for implementing acceleration, possibly reducing userland CPU usage greatly (<a href="../../../EricAnholt/">EricAnholt</a> is working on this). * Mach64 Render acceleration. This chip is pretty simple, and would make a good demonstration of how to accelerate Render to cover the cases needed by the existing xcompmgr demo. * Mach64 Yuv scaler usage. Switching from video overlays to Yuv scaling would fix issues with overlaying translucent images on top of the video. Performance would suffer though; some testing is likely needed.
X Compositing Manager
Note that the current xcompmgr application is a giant hack; a good project would be to write a "real" application that did the same job but was nicely split up and cleanly coded. However, the current one still has "issues" that will probably carry over into a rewrite.
* Paint shadows better. Current code recomputes the gaussian curve and the entire convolution with the sharp shadow each time a window is mapped or resized. Splitting the shadow into pieces (four corners, four edges and the middle) would help an awful lot in resize performance. * Check window stacking tracking. I've seen xcompmgr get confused about window stacking; some validation code could be added and then suitable bug fixes could be figured out. * Figure out some primitive hints so wms and apps can tell xcompmgr about translucency values and suchlike.
