Merge branch 'gallium-0.1' into gallium-0.2

+/** \mainpage
+
+ \section about About
+
+ Gallium3D is <a href="http://www.tungstengraphics.com/">Tungsten Graphics</a>'
+ new architecture for building 3D graphics drivers. Initially
+ supporting Mesa and Linux graphics drivers, Gallium3D is designed to allow
+ portability to all major operating systems and graphics interfaces.
+
+ Compared to existing Linux graphics drivers, Gallium3D will:
+
+ - Make drivers smaller and simpler.
+ Current DRI drivers are rather complicated. They're large, contain
+ duplicated code and are burdened with implementing many concepts tightly
+ tied to the OpenGL 1.x/2.x API.
+
+ - Model modern graphics hardware.
+ The new driver architecture is an abstraction of modern graphics hardware,
+ rather than an OpenGL->hardware translator. The new driver interface will
+ assume the presence of programmable vertex/fragment shaders and flexible
+ memory objects.
+
+ - Support multiple graphics APIs.
+ The OpenGL 3.0 API will be very different from OpenGL 1.x/2.x. We'd like a
+ driver model that is API-neutral so that it's not tied to a specific
+ graphics API.

+
+/** \page overview Overview
+
+ The public interface of a Gallium3D driver is described by the p_context.h
+ header file. The pipe_context structure is an abstract base class with
+ methods for:
+
+ - Setting rendering state (texture sampler state, vertex array info, drawing surfaces, etc.)
+
+ - Setting shader state, using the TGSI binary shader representation.
+
+ - Vertex array and indexed vertex array drawing.
+
+ - Region (memory) management for textures, renderbuffers, vertex buffers, etc.
+
+ - Hardware queries (number of texture units, max texture size, etc).
+
+ The p_state.h header defines all the state objects (such as polygon
+ rasterization options, blend modes, etc) and resources (drawing surfaces,
+ textures, memory buffers). The pipe interface uses "constant state" objects.
+ That is, state objects are created once and are immutable. State objects are
+ put into effect by binding them. This allows Gallium3D drivers to create
+ corresponding hardware state objects which can be quickly handled.
+
+ The p_defines.h header defines numerous constants and tokens (blend modes,
+ texture wrap modes, surface formats, etc.
+
+ The p_winsys.h header defines the window system and OS facilities which
+ Gallium3D drivers rely upon. For example, memory allocation is typically a
+ service the OS provides while window size/position information is provided by
+ the window system. Pipe drivers use the winsys interface to handle these
+ things.
+
+ By abstracting OS and window system services, pipe drivers are portable to
+ other platforms (e.g. embedded devices).
+*/
+
+/** \page statetracker The State Tracker
+
+ The state tracker is the piece which interfaces core Mesa to the Gallium3D
+ interface. It's responsible for translating Mesa state (blend modes, texture
+ state, etc) and drawing commands (like glDrawArrays and glDrawPixels) into
+ pipe objects and operations.
+
+ Traditional fixed-function OpenGL components (such as lighting and texture
+ combining) are implemented with shaders. OpenGL commands such as glDrawPixels
+ are translated into textured quadrilateral rendering. Basically, any
+ rendering operation that isn't directly supported by modern graphics hardware
+ is translated into a hardware-friendly form.
+
+ Future state trackers will be created for OpenGL 3.0 and OpenGL-ES 2.x.
+*/
+
+/** \page softpipe Softpipe Driver
+
+ The softpipe driver is a software implementation of the Gallium3D interface.
+ It will be used as a reference implementation and as a fallback driver when a
+ hardware driver isn't available. The softpipe driver will make extensive use
+ of run-time code generation to efficiently execute vertex, fragment and
+ rasterization operations.
+
+ \sa sp_winsys.h
+*/
+
+/** \page i915simple Simple i915 Driver
+
+ The i915 Gallium3D Driver is an initial hardware driver implementation within
+ the Gallium3D driver architecture. We expect that once complete this driver
+ will have equivalent functionality and performance to the current Mesa
+ i915tex driver, but from a much smaller codebase.
+
+ \sa i915_context.h
+ \sa i915_winsys.h
+*/
+
+/** \page failover Failover Module
+
+ The failover module acts as a selector between a hardware driver and the
+ softpipe driver. When the hardware can't implement a particular rendering
+ operation, the failover module will pass the request to the softpipe driver.
+ This is a different solution to the "software fallbacks" scheme of previous
+ Mesa drivers.
+
+ \sa fo_winsys.h
+*/
+
+/** \page draw Draw Module
+ The Draw module provides point/line/polygon rendering services such as
+ vertex transformation, polygon culling and clipping. It will be used by
+ drivers for hardware which lacks vertex transformation (such as the
+ i915/i945). It may also be instantiated and used directly by the state
+ tracker to implement some API functionality that doesn't map well to hardware
+ capabilities.
+
+ The interface of this module corresponds closely to the subset of the Gallium
+ Driver Interface which is relevent to these steps in the pipeline. Specifically
+ there are calls for:
+
+ - Vertex shader constant state objects
+ - Vertex buffer binding
+ - Vertex element layout (vertex fetch) constant state objects
+ - DrawArrays and DrawElements
+ - Rasterizer constant state objects.
+
+ The Draw module is effectively the part of \ref softpipe which is concerned with
+ vertex processing, split off into a separate module so that it can be reused
+ by drivers for rasterization-only hardware. As such it is also instantiated
+ by the \ref i915simple driver.
+
+ Additionally, there are cases in the Mesa OpenGL state_tracker where it is
+ required to obtain transformed vertices and yet it is anticipated that using
+ hardware transformation even if available would reduce performance, usually
+ because the setup costs or latency are prohibitive. For this reason the Mesa
+ state_tracker also instantiates a copy of this module.

+/** \page tgsi TGSI
+
+ The TGSI module provides a universal representation of shaders and
+ CPU-based execution of shaders. All Mesa vertex/fragment programs and shaders
+ are translated into the TGSI representation before being passed to the
+ driver. In turn, the driver will convert the TGSI instructions into
+ GPU-specific instructions. For hardware that lacks vertex or fragment shader
+ support, the TGSI's executor can be used. The TGSI executor includes support
+ for SSE code generation. Support for other processors (such as Cell) will be
+ added in the future.

+
+
+Notes about the EGL library:
+
+
+The EGL code here basically consists of two things:
+
+1. An EGL API dispatcher. This directly routes all the eglFooBar() API
+ calls into driver-specific functions.
+
+2. Fallbacks for EGL API functions. A driver _could_ implement all the
+ EGL API calls from scratch. But in many cases, the fallbacks provided
+ in libEGL (such as eglChooseConfig()) will do the job.
+
+
+
+Bootstrapping:
+
+When the apps calls eglOpenDisplay() a device driver is selected and loaded
+(look for dlsym() or LoadLibrary() in egldriver.c).
+
+The driver's _eglMain() function is then called. This driver function
+allocates, initializes and returns a new _EGLDriver object (usually a
+subclass of that type).
+
+As part of initialization, the dispatch table in _EGLDriver->API must be
+populated with all the EGL entrypoints. Typically, _eglInitDriverFallbacks()
+can be used to plug in default/fallback functions. Some functions like
+driver->API.Initialize and driver->API.Terminate _must_ be implemented
+with driver-specific code (no default/fallback function is possible).
+
+
+A bit later, the app will call eglInitialize(). This will get routed
+to the driver->API.Initialize() function. Any additional driver
+initialization that wasn't done in _eglMain() should be done at this
+point. Typically, this will involve setting up visual configs, etc.
+
+
+
+Special Functions:
+
+Certain EGL functions _must_ be implemented by the driver. This includes:
+
+eglCreateContext
+eglCreateWindowSurface
+eglCreatePixmapSurface
+eglCreatePBufferSurface
+eglMakeCurrent
+eglSwapBuffers
+
+Most of the EGLConfig-related functions can be implemented with the
+defaults/fallbacks. Same thing for the eglGet/Query functions.
+
+
+
+
+Teardown:
+
+When eglTerminate() is called, the driver->API.Terminate() function is
+called. The driver should clean up after itself. eglTerminate() will
+then close/unload the driver (shared library).
+
+
+
+
+Subclassing:
+
+The internal libEGL data structures such as _EGLDisplay, _EGLContext,
+_EGLSurface, etc should be considered base classes from which drivers
+will derive subclasses.

- * For the most part, data is just copied from \c depth_bits, \c stencil_bits,
- * \c db_modes, and \c visType into each \c __GLcontextModes element.
- * However, the meanings of \c fb_format and \c fb_type require further
- * explanation. The \c fb_format specifies which color components are in
- * each pixel and what the default order is. For example, \c GL_RGB specifies
- * that red, green, blue are available and red is in the "most significant"
- * position and blue is in the "least significant". The \c fb_type specifies
- * the bit sizes of each component and the actual ordering. For example, if
- * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11]
- * are the blue value, bits [10:5] are the green value, and bits [4:0] are
- * the red value.
- *
- * One sublte issue is the combination of \c GL_RGB or \c GL_BGR and either
- * of the \c GL_UNSIGNED_INT_8_8_8_8 modes. The resulting mask values in the
- * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or
- * \c GL_BGRA case, except the \c alphaMask is zero. This means that, as
- * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8
- * still uses 32-bits.
- *
- * If in doubt, look at the tables used in the function.
- *
- * \param ptr_to_modes Pointer to a pointer to a linked list of
- * \c __GLcontextModes. Upon completion, a pointer to
- * the next element to be process will be stored here.
- * If the function fails and returns \c GL_FALSE, this
- * value will be unmodified, but some elements in the
- * linked list may be modified.
- * \param fb_format Format of the framebuffer. Currently only \c GL_RGB,
- * \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported.
- * \param fb_type Type of the pixels in the framebuffer. Currently only
- * \c GL_UNSIGNED_SHORT_5_6_5,
- * \c GL_UNSIGNED_SHORT_5_6_5_REV,
- * \c GL_UNSIGNED_INT_8_8_8_8, and
- * \c GL_UNSIGNED_INT_8_8_8_8_REV are supported.
- * \param depth_bits Array of depth buffer sizes to be exposed.
- * \param stencil_bits Array of stencil buffer sizes to be exposed.
- * \param num_depth_stencil_bits Number of entries in both \c depth_bits and
- * \c stencil_bits.
- * \param db_modes Array of buffer swap modes. If an element has a
- * value of \c GLX_NONE, then it represents a
- * single-buffered mode. Other valid values are
- * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and
- * \c GLX_SWAP_UNDEFINED_OML. See the
- * GLX_OML_swap_method extension spec for more details.
- * \param num_db_modes Number of entries in \c db_modes.
- * \param visType GLX visual type. Usually either \c GLX_TRUE_COLOR or
- * \c GLX_DIRECT_COLOR.
- *
- * \returns
- * \c GL_TRUE on success or \c GL_FALSE on failure. Currently the only
- * cause of failure is a bad parameter (i.e., unsupported \c fb_format or
- * \c fb_type).
- *
- * \todo
- * There is currently no way to support packed RGB modes (i.e., modes with
- * exactly 3 bytes per pixel) or floating-point modes. This could probably
- * be done by creating some new, private enums with clever names likes
- * \c GL_UNSIGNED_3BYTE_8_8_8, \c GL_4FLOAT_32_32_32_32,

+ CROSS-PLATFORM PORTABILITY GUIDELINES FOR GALLIUM3D
+
+
+= General Considerations =
+
+The state tracker and winsys driver support a rather limited number of
+platforms. However, the pipe drivers are meant to run in a wide number of
+platforms. Hence the pipe drivers, the auxiliary modules, and all public
+headers in general, should strictly follow these guidelines to ensure
+
+
+= Compiler Support =
+
+* Include the p_compiler.h.
+
+* Don't use the 'inline' keyword, use the INLINE macro in p_compiler.h instead.
+
+* Cast explicitly when converting to integer types of smaller sizes.
+
+* Cast explicitly when converting between float, double and integral types.
+
+* Don't use named struct initializers.
+
+* Don't use variable number of macro arguments. Use static inline functions
+instead.
+
+* Don't use C99 features.
+
+= Standard Library =
+
+* Avoid including standard library headers. Most standard library functions are
+not available in Windows Kernel Mode. Use the appropriate p_*.h include.
+
+== Memory Allocation ==
+
+* Use MALLOC, CALLOC, FREE instead of the malloc, calloc, free functions.
+
+* Use align_pointer() function defined in u_memory.h for aligning pointers
+ in a portable way.
+
+== Debugging ==
+
+* Use the functions/macros in p_debug.h.
+
+* Don't include assert.h, call abort, printf, etc.
+
+
+= Code Style =
+
+== Inherantice in C ==
+
+The main thing we do is mimic inheritance by structure containment.
+
+Here's a silly made-up example:
+
+/* base class */
+struct buffer
+{
+ int size;
+ void (*validate)(struct buffer *buf);
+};
+
+/* sub-class of bufffer */
+struct texture_buffer
+{
+ struct buffer base; /* the base class, MUST COME FIRST! */
+ int format;
+ int width, height;
+};
+
+
+Then, we'll typically have cast-wrapper functions to convert base-class
+pointers to sub-class pointers where needed:
+
+static inline struct vertex_buffer *vertex_buffer(struct buffer *buf)
+{
+ return (struct vertex_buffer *) buf;
+}
+
+
+To create/init a sub-classed object:
+
+struct buffer *create_texture_buffer(int w, int h, int format)
+{
+ struct texture_buffer *t = malloc(sizeof(*t));
+ t->format = format;
+ t->width = w;
+ t->height = h;
+ t->base.size = w * h;
+ t->base.validate = tex_validate;
+ return &t->base;
+}
+
+Example sub-class method:
+
+void tex_validate(struct buffer *buf)
+{
+ struct texture_buffer *tb = texture_buffer(buf);
+ assert(tb->format);
+ assert(tb->width);
+ assert(tb->height);
+}
+
+
+Note that we typically do not use typedefs to make "class names"; we use
+'struct whatever' everywhere.
+
+Gallium's pipe_context and the subclassed psb_context, etc are prime examples
+of this. There's also many examples in Mesa and the Mesa state tracker.

+ /**
+ * @file
+ * Constant State Object (CSO) cache.
+ *
+ * The basic idea is that the states are created via the
+ * create_state/bind_state/delete_state semantics. The driver is expected to
+ * perform as much of the Gallium state translation to whatever its internal
+ * representation is during the create call. Gallium then has a caching
+ * mechanism where it stores the created states. When the pipeline needs an
+ * actual state change, a bind call is issued. In the bind call the driver
+ * gets its already translated representation.
+ *
+ * Those semantics mean that the driver doesn't do the repeated translations
+ * of states on every frame, but only once, when a new state is actually
+ * created.
+ *
+ * Even on hardware that doesn't do any kind of state cache, it makes the
+ * driver look a lot neater, plus it avoids all the redundant state
+ * translations on every frame.
+ *
+ * Currently our constant state objects are:
+ * - alpha test
+ * - blend
+ * - depth stencil
+ * - fragment shader
+ * - rasterizer (old setup)
+ * - sampler
+ * - vertex shader
+ *
+ * Things that are not constant state objects include:
+ * - blend_color
+ * - clip_state
+ * - clear_color_state
+ * - constant_buffer
+ * - feedback_state
+ * - framebuffer_state
+ * - polygon_stipple
+ * - scissor_state
+ * - texture_state
+ * - viewport_state

+ *
+ * Flow control information:
+ *
+ * Since we operate on 'quads' (4 pixels or 4 vertices in parallel)
+ * flow control statements (IF/ELSE/ENDIF, LOOP/ENDLOOP) require special
+ * care since a condition may be true for some quad components but false
+ * for other components.
+ *
+ * We basically execute all statements (even if they're in the part of
+ * an IF/ELSE clause that's "not taken") and use a special mask to
+ * control writing to destination registers. This is the ExecMask.
+ * See store_dest().
+ *
+ * The ExecMask is computed from three other masks (CondMask, LoopMask and
+ * ContMask) which are controlled by the flow control instructions (namely:
+ * (IF/ELSE/ENDIF, LOOP/ENDLOOP and CONT).

+/*
+ * History
+ *
+ * 2008-01-20 Holger Weiss <holger@jhweiss.de> for C99-snprintf 1.1:
+ *
+ * Fixed the detection of infinite floating point values on IRIX (and
+ * possibly other systems) and applied another few minor cleanups.
+ *
+ * 2008-01-06 Holger Weiss <holger@jhweiss.de> for C99-snprintf 1.0:
+ *
+ * Added a lot of new features, fixed many bugs, and incorporated various
+ * improvements done by Andrew Tridgell <tridge@samba.org>, Russ Allbery
+ * <rra@stanford.edu>, Hrvoje Niksic <hniksic@xemacs.org>, Damien Miller
+ * <djm@mindrot.org>, and others for the Samba, INN, Wget, and OpenSSH
+ * projects. The additions include: support the "e", "E", "g", "G", and
+ * "F" conversion specifiers (and use conversion style "f" or "F" for the
+ * still unsupported "a" and "A" specifiers); support the "hh", "ll", "j",
+ * "t", and "z" length modifiers; support the "#" flag and the (non-C99)
+ * "'" flag; use localeconv(3) (if available) to get both the current
+ * locale's decimal point character and the separator between groups of
+ * digits; fix the handling of various corner cases of field width and
+ * precision specifications; fix various floating point conversion bugs;
+ * handle infinite and NaN floating point values; don't attempt to write to
+ * the output buffer (which may be NULL) if a size of zero was specified;
+ * check for integer overflow of the field width, precision, and return
+ * values and during the floating point conversion; use the OUTCHAR() macro
+ * instead of a function for better performance; provide asprintf(3) and
+ * vasprintf(3) functions; add new test cases. The replacement functions
+ * have been renamed to use an "rpl_" prefix, the function calls in the
+ * main project (and in this file) must be redefined accordingly for each
+ * replacement function which is needed (by using Autoconf or other means).
+ * Various other minor improvements have been applied and the coding style
+ * was cleaned up for consistency.
+ *
+ * 2007-07-23 Holger Weiss <holger@jhweiss.de> for Mutt 1.5.13:
+ *
+ * C99 compliant snprintf(3) and vsnprintf(3) functions return the number
+ * of characters that would have been written to a sufficiently sized
+ * buffer (excluding the '\0'). The original code simply returned the
+ * length of the resulting output string, so that's been fixed.
+ *
+ * 1998-03-05 Michael Elkins <me@mutt.org> for Mutt 0.90.8:
+ *
+ * The original code assumed that both snprintf(3) and vsnprintf(3) were
+ * missing. Some systems only have snprintf(3) but not vsnprintf(3), so
+ * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ * 1998-01-27 Thomas Roessler <roessler@does-not-exist.org> for Mutt 0.89i:
+ *
+ * The PGP code was using unsigned hexadecimal formats. Unfortunately,
+ * unsigned formats simply didn't work.
+ *
+ * 1997-10-22 Brandon Long <blong@fiction.net> for Mutt 0.87.1:
+ *
+ * Ok, added some minimal floating point support, which means this probably
+ * requires libm on most operating systems. Don't yet support the exponent
+ * (e,E) and sigfig (g,G). Also, fmtint() was pretty badly broken, it just
+ * wasn't being exercised in ways which showed it, so that's been fixed.
+ * Also, formatted the code to Mutt conventions, and removed dead code left
+ * over from the original. Also, there is now a builtin-test, run with:
+ * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm && ./snprintf
+ *
+ * 2996-09-15 Brandon Long <blong@fiction.net> for Mutt 0.43:
+ *
+ * This was ugly. It is still ugly. I opted out of floating point
+ * numbers, but the formatter understands just about everything from the
+ * normal C string format, at least as far as I can tell from the Solaris
+ * 2.5 printf(3S) man page.
+ */
+
+/*
+ * ToDo
+ *
+ * - Add wide character support.
+ * - Add support for "%a" and "%A" conversions.
+ * - Create test routines which predefine the expected results. Our test cases
+ * usually expose bugs in system implementations rather than in ours :-)
+ */
+
+/*
+ * Usage
+ *
+ * 1) The following preprocessor macros should be defined to 1 if the feature or
+ * file in question is available on the target system (by using Autoconf or
+ * other means), though basic functionality should be available as long as
+ * HAVE_STDARG_H and HAVE_STDLIB_H are defined correctly:

+/* 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.

+ *
+ * For the 965, we create two state pools for state cache entries. Objects
+ * will be allocated into the pools depending on which state base address
+ * their pointer is relative to in other 965 state.
+ *
+ * The state pools are relatively simple: As objects are allocated, increment
+ * the offset to allocate space. When the pool is "full" (rather, close to
+ * full), we reset the pool and reset the state cache entries that point into
+ * the pool.

+ 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.

+ * _glthread_GetTSD() Get thread-specific data
+ * _glthread_SetTSD() Set thread-specific data

+This directory contains Python bindings to Gallium3D. It looks like a state
+tracker from the pipe driver perspective, and it looks like a pipe driver from
+the python script perspective.
+
+
+To build you'll need:
+* Python (with development packages)
+* SCons
+* SWIG
+* Python Imaging Library with TK support (for the samples)
+
+Invoke scons on the top dir as
+
+ scons statetrackers=python
+
+To use do
+
+ export PYTHONPATH=build/XXXX-XXXX-XXXX/gallium/state_trackers/python
+
+and then try running
+
+ python src/gallium/state_trackers/python/samples/tri.py
+
+which should show a triangle.
+
+
+This is still work in progress:
+- errors are not handled properly and almost always result in crash
+- state atoms with array members are awkward to set
+- there no efficient way to view images

+; DO NOT EDIT - This file generated automatically by mesadef.py script
+;DESCRIPTION 'Mesa (OpenGL work-alike) for Win32'
+VERSION 6.5
+;
+; Module definition file for Mesa (OPENGL32.DLL)
+;
+; Note: The OpenGL functions use the STDCALL
+; function calling convention. Microsoft's
+; OPENGL32 uses this convention and so must the
+; Mesa OPENGL32 so that the Mesa DLL can be used
+; as a drop-in replacement.
+;
+; The linker exports STDCALL entry points with
+; 'decorated' names; e.g., _glBegin@0, where the
+; trailing number is the number of bytes of
+; parameter data pushed onto the stack. The
+; callee is responsible for popping this data
+; off the stack, usually via a RETF n instruction.
+;
+; However, the Microsoft OPENGL32.DLL does not export
+; the decorated names, even though the calling convention
+; is STDCALL. So, this module definition file is
+; needed to force the Mesa OPENGL32.DLL to export the
+; symbols in the same manner as the Microsoft DLL.
+; Were it not for this problem, this file would not
+; be needed (for the gl* functions) since the entry
+; points are compiled with dllexport declspec.
+;
+; However, this file is still needed to export "internal"
+; Mesa symbols for the benefit of the OSMESA32.DLL.

+/**

+ *
+ * All the XMesa* API functions.
+ *
+ *
+ * NOTES:
+ *
+ * The window coordinate system origin (0,0) is in the lower-left corner
+ * of the window. X11's window coordinate origin is in the upper-left
+ * corner of the window. Therefore, most drawing functions in this
+ * file have to flip Y coordinates.
+ *
+ * Define USE_XSHM in the Makefile with -DUSE_XSHM if you want to compile
+ * in support for the MIT Shared Memory extension. If enabled, when you
+ * use an Ximage for the back buffer in double buffered mode, the "swap"
+ * operation will be faster. You must also link with -lXext.
+ *
+ * Byte swapping: If the Mesa host and the X display use a different
+ * byte order then there's some trickiness to be aware of when using
+ * XImages. The byte ordering used for the XImage is that of the X
+ * display, not the Mesa host.
+ * The color-to-pixel encoding for True/DirectColor must be done
+ * according to the display's visual red_mask, green_mask, and blue_mask.
+ * If XPutPixel is used to put a pixel into an XImage then XPutPixel will
+ * do byte swapping if needed. If one wants to directly "poke" the pixel
+ * into the XImage's buffer then the pixel must be byte swapped first.
