Merge branch 'gallium-0.1' into gallium-0.2

A first attempt at moving gallium onto a branch directly off master... It will be interesting to see how much work this takes to get running.

+/* Glossary:
+ *
+ * URB - uniform resource buffer.  A mid-sized buffer which is
+ * partitioned between the fixed function units and used for passing
+ * values (vertices, primitives, constants) between them.
+ *
+ * CURBE - constant URB entry.  An urb region (entry) used to hold
+ * constant values which the fixed function units can be instructed to
+ * preload into the GRF when spawining a thread.
+ *
+ * VUE - vertex URB entry.  An urb entry holding a vertex and usually
+ * a vertex header.  The header contains control information and
+ * things like primitive type, Begin/end flags and clip codes.
+ *
+ * PUE - primitive URB entry.  An urb entry produced by the setup (SF)
+ * unit holding rasterization and interpolation parameters.
+ *
+ * GRF - general register file.  One of several register files
+ * addressable by programmed threads.  The inputs (r0, payload, curbe,
+ * urb) of the thread are preloaded to this area before the thread is
+ * spawned.  The registers are individually 8 dwords wide and suitable
+ * for general usage.  Registers holding thread input values are not
+ * special and may be overwritten.
+ *
+ * MRF - message register file.  Threads communicate (and terminate)
+ * by sending messages.  Message parameters are placed in contigous
+ * MRF registers.  All program output is via these messages.  URB
+ * entries are populated by sending a message to the shared URB
+ * function containing the new data, together with a control word,
+ * often an unmodified copy of R0.
+ *
+ * R0 - GRF register 0.  Typically holds control information used when
+ * sending messages to other threads.
+ *
+ * EU or GEN4 EU: The name of the programmable subsystem of the
+ * i965 hardware.  Threads are executed by the EU, the registers
+ * described above are part of the EU architecture.
+ *
+ * Fixed function units:
+ *
+ * CS - Command streamer.  Notional first unit, little software
+ * interaction.  Holds the URB entries used for constant data, ie the
+ * CURBEs.
+ *
+ * VF/VS - Vertex Fetch / Vertex Shader.  The fixed function part of
+ * this unit is responsible for pulling vertices out of vertex buffers
+ * in vram and injecting them into the processing pipe as VUEs.  If
+ * enabled, it first passes them to a VS thread which is a good place
+ * for the driver to implement any active vertex shader.
+ *
+ * GS - Geometry Shader.  This corresponds to a new DX10 concept.  If
+ * enabled, incoming strips etc are passed to GS threads in individual
+ * line/triangle/point units.  The GS thread may perform arbitary
+ * computation and emit whatever primtives with whatever vertices it
+ * chooses.  This makes GS an excellent place to implement GL's
+ * unfilled polygon modes, though of course it is capable of much
+ * more.  Additionally, GS is used to translate away primitives not
+ * handled by latter units, including Quads and Lineloops.
+ *
+ * CS - Clipper.  Mesa's clipping algorithms are imported to run on
+ * this unit.  The fixed function part performs cliptesting against
+ * the 6 fixed clipplanes and makes descisions on whether or not the
+ * incoming primitive needs to be passed to a thread for clipping.
+ * User clip planes are handled via cooperation with the VS thread.
+ *
+ * SF - Strips Fans or Setup: Triangles are prepared for
+ * rasterization.  Interpolation coefficients are calculated.
+ * Flatshading and two-side lighting usually performed here.
+ *
+ * WM - Windower.  Interpolation of vertex attributes performed here.
+ * Fragment shader implemented here.  SIMD aspects of EU taken full
+ * advantage of, as pixels are processed in blocks of 16.
+ *
+ * CC - Color Calculator.  No EU threads associated with this unit.
+ * Handles blending and (presumably) depth and stencil testing.

+ *    - tell vbuf stage how to build hw vertices directly
+ *    - pass vbuf stage a buffer pointer for direct emit to agp/vram.

+ *
+ * Vertices are just an array of floats, with all the attributes

+                             TRACE PIPE DRIVER
+
+
+= About =
+
+This directory contains a Gallium3D pipe driver which traces all incoming calls.
+
+
+= Build Instructions =
+
+To build, invoke scons on the top dir as
+ 
+ scons statetrackers=mesa drivers=softpipe,i915simple,trace winsys=xlib
+
+
+= Usage =
+
+To use do
+
+ ln -s libGL.so build/linux-x86-debug/gallium/winsys/xlib/libGL.so.1
+ export LD_LIBRARY_PATH=$PWD/build/linux-x86-debug/gallium/winsys/xlib
+
+ensure the right libGL.so is being picked by doing
+
+ ldd progs/trivial/tri 
+
+and then try running
+
+ GALLIUM_TRACE=tri.trace progs/trivial/tri
+
+which should create a tri.trace file, which is an XML file. You can view copying 
+trace.xsl to the same directory, and opening with a XSLT capable browser such as 
+Firefox or Internet Explorer.
+
+
+= Integrating =
+
+You can integrate the trace pipe driver either inside the state tracker or the 
+winsys. The procedure on both cases is the same. Let's assume you have a 
+pipe_screen and a pipe_context pair obtained by the usual means (variable and 
+function names are just for illustration purposes):
+
+  real_screen = real_screen_create(...);
+  
+  real_context = real_context_create(...);
+  
+The trace screen and pipe_context is then created by doing
+
+  trace_screen = trace_screen_create(real_screen);
+  
+  trace_context = trace_context_create(trace_screen, real_context);
+  
+You can then simply use trace_screen and trace_context instead of real_screen
+and real_context.
+
+Do not call trace_winsys_create. Simply pass trace_screen->winsys or 
+trace_context->winsys in places you would pass winsys.
+
+You can create as many contexts you wish. Just ensure that you don't mistake 
+trace_screen with real_screen when creating them.
