libgl1-amber-dri 21.3.9-0ubuntu1 (ppc64el binary) in ubuntu mantic

 This version of Mesa provides GLX and DRI capabilities: it is capable of
 both direct and indirect rendering. For direct rendering, it can use DRI
 modules from the libgl1-mesa-dri package to accelerate drawing.
 .
 This package does not include the OpenGL library itself, only the DRI
 modules for accelerating direct rendering.
 .
 For a complete description of Mesa Amber, please look at the
 libglx-amber0 package.
