Hello 1. We have implemented hardware acceleration with KAA module. However, the hardware function registered for Solid and Copy is not called always, instead software fillrect function is called. This is because kaaPixmapIsOffscreen returns false. As mentioned below, since KAA manages offscreen memory as a linear area is it necessary to check if pixmap is in offscreen memory before calling Kaa registered hardware functions?
2. I understand that driver hardware acceleration functions cannot be called on pixmaps in system memory. How about trying following:: We call driver level functions for pixmap creation and destruction (driver managed memory) instead of kaaCreatePixmap/kaaDestroyPixmap and call hardware acceleration functions on these pixmaps without checking if pixmap is in offscreen memory or not. Is that okay? Will this call the registered hardware level function all the time? <-------------------------------------------------------- As mentioned at "http://www.usenix.org/events/usenix04/tech/freenix/full_papers/anholt/anholt_html/index.html";, XAA manages offscreen memory by treating it as a large 2D area at a set number of bits per pixel (bpp) while KAA manages offscreen memory as a linear area. XAA implements a small subset of Render operations. It handles only cases where the destination picture is located in offscreen memory and the source picture is not. Because XAA's 2D offscreen memory layout prevents the offscreen storage of pixmaps with a bpp different from the screen, many source images will be located in system memory anyway. -----------------------------------------------------------> Thanks and Regards, Vrushali _______________________________________________ xorg-devel mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-devel
