https://bugs.freedesktop.org/show_bug.cgi?id=41263 --- Comment #2 from Simon Farnsworth <simon.farnsworth@xxxxxxxxxxxx> 2011-09-28 10:07:53 PDT --- I think it may be core Mesa at fault. main/teximage.c:2779 gl_format texFormat = _mesa_choose_texture_format(ctx, texObj, target, level, internalFormat, GL_NONE, GL_NONE); is called when internalFormat is GL_RGB. Gallium, not unreasonably, treats this as "choose a nice fast GL_RGB style format", and chooses a reversed format to that of the source. The result is a slow software copy, not a fast hardware copy. So, two possibilities present themselves to me: 1) Gallium should learn to do swizzled hardware blits with a textured quad. 2) Core Mesa should give Gallium more information about the source, so that it can choose a matching format if possible. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
