It turns out that the use of fbo blit is one of the root cause which lead to slow drawing, especially slow filling rects. We guess there should be a performance bug in the mesa driver or even in the kernel drm driver. Currently, the only thing glamor can do is to avoid calling those functions. We check whether the copy source and destination has overlapped region, if it has, we have to call fbo blit function. If it has not, we can load the source texture directly and draw it to the target texture. We totally don't need the glCopyPixels here, so remove it. By apply this patch, the rendering time of firefox-planet-gnome decrease to 10.4 seconds. At the same platform, uxa driver get 13 seconds. This is the first time we get better performance than uxa driver. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com> |

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
