Subject: mesa: new MESA_EXTENSION_MAX_YEAR env var

If set to year X, only report extensions up to that year.  This is a
work-around for games that try to copy the extensions string to a fixed
size buffer and overflow.  If a game was released in year X, setting
MESA_EXTENSION_MAX_YEAR to that year will likely fix the problem.

    mesa, mesa/st: handle read color clamping properly

    (I'll squash the st/mesa part to a separate commit. -Marek)

    We set IMAGE_CLAMP_BIT in the caller based on _ClampReadColor, where
    the operation mandates it.

    TODO: did I get the set of operations mandating it right?

    mesa: clamp color queries if and only if fragment clamping is enabled

commit 9940a3e31c2fb76cc3d28b15ea78dde369825107
Author: Luca Barbieri <luca@luca-barbieri.com>
Date:   Wed Aug 25 00:00:16 2010 +0200

    mesa: introduce derived _ClampXxxColor state resolving FIXED_ONLY

    To do this, we make ClampColor call FLUSH_VERTICES with the appropriate
    _NEW flag.

    We introduce _NEW_FRAG_CLAMP since fragment clamping has wide-ranging
    effects, despite being in the Color attrib group.

    This may be easily changed by s/_NEW_FRAG_CLAMP/_NEW_COLOR/g

 <p>
-Mesa is distributed in several parts:
+The Mesa package is named MesaLib-x.y.z.{tar.bz2, tar.gz, zip} where x.y.z
+is the version.  There are three types of compressed archives.
 </p>
-<ul>
-<li><b>MesaLib-x.y.z</b> - the main Mesa library source code, drivers
-    and documentation.
-</li>
-<li><b>MesaDemos-x.y.z</b> - OpenGL demonstration and test programs.
-    Most of the programs require GLUT (either the
-    <a href="http://www.opengl.org/resources/libraries/glut"
-    target="_parent">original GLUT by Mark Kilgard</a> or
-    <a href="http://freeglut.sourceforge.net" target="_parent">freeglut</a> or
-    <a href="http://openglut.sourceforge.net" target="_parent">OpenGLUT</a>).
-</li>
-<li><b>MesaGLUT-x.y.z</b> - Mark Kilgard's GLUT, easily compiled and used
-    with Mesa.  Plus, other implementation of GLUT for DOS, OS/2, BeOS, etc.
-</li>
-</ul>
-
 <p>
-If you're not interested in running the demos, you'll only need the first
-package.
+There's also the MesaGLUT-x.y.z.{tar.bz2, tar.gz, zip} packages which
+contain Mark Kilgard's GLUT library.
+This is optional.
+Most Linux distributions include an implementation of GLUT (such as freeglut).
 </p>
-
 <p>
-If you're new to this and not sure what you're doing, grab all three packages.
+In the past, the Mesa demos collection was distributed as
+MesaDemos-x.y.z.{tar.bz2, tar.gz, zip}.
+Now, the
+<a href="ftp://ftp.freedesktop.org/pub/mesa/demos/" target="_parent">
+Mesa demos</a> are distributed separately.
 </p>

+
+<p>
+Mesa 7.10.2 is a bug fix release which fixes bugs found since the 7.10 release.
+</p>
+<p>
+Mesa 7.10.2 implements the OpenGL 2.1 API, but the version reported by
+glGetString(GL_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 2.1.
+</p>
+<p>
+See the <a href="install.html">Compiling/Installing page</a> for prerequisites
+for DRI hardware acceleration.

+<H1>Introduction</H1>
+
+<p>
+The Gallium llvmpipe driver is a software rasterizer that uses LLVM to
+do runtime code generation.
+Shaders, point/line/triangle rasterization and vertex processing are
+implemented with LLVM IR which is translated to x86 or x86-64 machine
+code.
+Also, the driver is multithreaded to take advantage of multiple CPU cores
+(up to 8 at this time).
+It's the fastest software rasterizer for Mesa.

+<h1>Building</h1>
+
+To build everything on Linux invoke scons as:
+
+<pre>
+  scons build=debug libgl-xlib
+</pre>
+
+Alternatively, you can build it with GNU make, if you prefer, by invoking it as
+
+<pre>
+  make linux-llvm
+</pre>
+
+but the rest of these instructions assume that scons is used.
+
+For windows is everything the except except the winsys:
+
+<pre>
+  scons build=debug libgl-gdi
+</pre>
+
+
+<h1>Using</h1>
+
+On Linux, building will create a drop-in alternative for libGL.so into
+
+<pre>
+  build/foo/gallium/targets/libgl-xlib/libGL.so
+</pre>
+or
+<pre>
+  lib/gallium/libGL.so
+</pre>
+
+To use it set the LD_LIBRARY_PATH environment variable accordingly.
+
+For performance evaluation pass debug=no to scons, and use the corresponding
+lib directory without the "-debug" suffix.
+
+On Windows, building will create a drop-in alternative for opengl32.dll. To use
+it put it in the same directory as the application. It can also be used by
+replacing the native ICD driver, but it's quite an advanced usage, so if you
+need to ask, don't even try it.
+
+
+<h1>Profiling</h1>
+
+To profile llvmpipe you should pass the options
+
+<pre>
+  scons build=profile <same-as-before>
+</pre>
+
+This will ensure that frame pointers are used both in C and JIT functions, and
+that no tail call optimizations are done by gcc.
+
+To better profile JIT code you'll need to build LLVM with oprofile integration.
