 I know mesa is a open source implementation of OpenGL, obviously
 mesa will afford OpenGL API. DRI is short for Direct Rendering
 Infrastructure, I have chosen options like:
 Device Drivers ---
   Graphics support ---
   *  Direct Rendering Manager ---

this is DRM. This one manages allocation of memory for video devices.

   *ATI Radeon
   [*]  Enable modesetting on radeon by default
 
 Does this mean that DRI libraries are built into kernel? 

No.

 If not, who
 contains DRI? Also who affords GLX libraries? Mesa or Xorg?

DRI is part of mesa. Mesa also provides the GLX libraries.

Best,

Thanks and  I wish you could help answer this question.Now I know Mesa provides 
DRI and GLX, when I installed xorg-server,there're also libraries named like 
libdri.so and libglx.so in /etc/X11/(somewhere).What I don't understand is, 
why Xorg-server still provides its own DRI and GLX while Mesahas done this 
already?

Thanks, the web pages you provided I have already read before, these don't seem 
to provide helpful issues for my questions.

libglx can also be provided by driver packages. You can select the
xorg one or others via eselect;

proxy adam # eselect opengl list
Available OpenGL implementations:
  [1]   ati *
  [2]   xorg-x11

Also, I imagine those kernel options supply an interface for the DRM/DRI 
driver.

Thank you very much ! I think I worked it out :)
