- * DRI utility functions.
- *
- * This module acts as glue between GLX and the actual hardware driver.  A DRI
- * driver doesn't really \e have to use any of this - it's optional.  But, some
- * useful stuff is done here that otherwise would have to be duplicated in most
- * drivers.
- * 
- * Basically, these utility functions take care of some of the dirty details of
- * screen initialization, context creation, context binding, DRM setup, etc.
- *
- * These functions are compiled into each DRI driver so libGL.so knows nothing
- * about them.

-;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.

+;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.

+;

- * \section MainIntroduction Introduction
- *
- * The Mesa Main module consists of all the files in the main/ directory.
- * Among the features of this module are:
- * <UL>
- * <LI> Structures to represent most GL state </LI>
- * <LI> State set/get functions </LI>
- * <LI> Display lists </LI>
- * <LI> Texture unit, object and image handling </LI>
- * <LI> Matrix and attribute stacks </LI>
- * </UL>
- *
- * Other modules are responsible for API dispatch, vertex transformation,
- * point/line/triangle setup, rasterization, vertex array caching,
- * vertex/fragment programs/shaders, etc.
- *

+ *

+ * The Mesa Main module consists of all the files in the main/ directory.

+ * Among the features of this module are:

+ * <UL>

+ * <LI> Structures to represent most GL state </LI>

+ * <LI> State set/get functions </LI>

+ * <LI> Display lists </LI>

+ * <LI> Texture unit, object and image handling </LI>

+ * <LI> Matrix and attribute stacks </LI>

+ * </UL>

+ *

+ * Other modules are responsible for API dispatch, vertex transformation,

+ * point/line/triangle setup, rasterization, vertex array caching,

+ * vertex/fragment programs/shaders, etc.

-/* This is a table driven implemetation of the glGet*v() functions.
- * The basic idea is that most getters just look up an int somewhere
- * in struct gl_context and then convert it to a bool or float according to
- * which of glGetIntegerv() glGetBooleanv() etc is being called.
- * Instead of generating code to do this, we can just record the enum
- * value and the offset into struct gl_context in an array of structs.  Then
- * in glGet*(), we lookup the struct for the enum in question, and use
- * the offset to get the int we need.
- *
- * Sometimes we need to look up a float, a boolean, a bit in a
- * bitfield, a matrix or other types instead, so we need to track the
- * type of the value in struct gl_context.  And sometimes the value isn't in
- * struct gl_context but in the drawbuffer, the array object, current texture
- * unit, or maybe it's a computed value.  So we need to also track
- * where or how to find the value.  Finally, we sometimes need to
- * check that one of a number of extensions are enabled, the GL
- * version or flush or call _mesa_update_state().  This is done by
- * attaching optional extra information to the value description
- * struct, it's sort of like an array of opcodes that describe extra
- * checks or actions.
- *
- * Putting all this together we end up with struct value_desc below,
- * and with a couple of macros to help, the table of struct value_desc
- * is about as concise as the specification in the old python script.

+/* This is a table driven implemetation of the glGet*v() functions.

+ * The basic idea is that most getters just look up an int somewhere

+ * in struct gl_context and then convert it to a bool or float according to

+ * which of glGetIntegerv() glGetBooleanv() etc is being called.

+ * Instead of generating code to do this, we can just record the enum

+ * value and the offset into struct gl_context in an array of structs.  Then

+ * in glGet*(), we lookup the struct for the enum in question, and use

+ * the offset to get the int we need.

+ *

+ * Sometimes we need to look up a float, a boolean, a bit in a

+ * bitfield, a matrix or other types instead, so we need to track the

+ * type of the value in struct gl_context.  And sometimes the value isn't in

+ * struct gl_context but in the drawbuffer, the array object, current texture

+ * unit, or maybe it's a computed value.  So we need to also track

+ * where or how to find the value.  Finally, we sometimes need to

+ * check that one of a number of extensions are enabled, the GL

+ * version or flush or call _mesa_update_state().  This is done by

+ * attaching optional extra information to the value description

+ * struct, it's sort of like an array of opcodes that describe extra

+ * checks or actions.

+ *

+ * Putting all this together we end up with struct value_desc below,

+ * and with a couple of macros to help, the table of struct value_desc

+ * is about as concise as the specification in the old python script.

- * Functions for allocating/managing renderbuffers.
- * Also, routines for reading/writing software-based renderbuffer data as
- * ubytes, ushorts, uints, etc.
- *
- * The 'alpha8' renderbuffer is interesting.  It's used to add a software-based
- * alpha channel to RGB renderbuffers.  This is done by wrapping the RGB
- * renderbuffer with the alpha renderbuffer.  We can do this because of the
- * OO-nature of renderbuffers.
- *
- * Down the road we'll use this for run-time support of 8, 16 and 32-bit
- * color channels.  For example, Mesa may use 32-bit/float color channels
- * internally (swrast) and use wrapper renderbuffers to convert 32-bit
- * values down to 16 or 8-bit values for whatever kind of framebuffer we have.

+ * Functions for allocating/managing renderbuffers.

+ * Also, routines for reading/writing software-based renderbuffer data as

+ * ubytes, ushorts, uints, etc.

+ *

+ * The 'alpha8' renderbuffer is interesting.  It's used to add a software-based

+ * alpha channel to RGB renderbuffers.  This is done by wrapping the RGB

+ * renderbuffer with the alpha renderbuffer.  We can do this because of the

+ * OO-nature of renderbuffers.

+ *

+ * Down the road we'll use this for run-time support of 8, 16 and 32-bit

+ * color channels.  For example, Mesa may use 32-bit/float color channels

+ * internally (swrast) and use wrapper renderbuffers to convert 32-bit

+ * values down to 16 or 8-bit values for whatever kind of framebuffer we have.

- * With GL_EXT_stencil_two_side, calling glStencilOp/Func/Mask() only the

- *
- * This problem is solved by keeping three sets of stencil state:

+ * With GL_EXT_stencil_two_side, calling glStencilOp/Func/Mask() only the

+ * glStencilFuncSeparateATI(GLenum frontfunc, GLenum backfunc, ...)  vs.

+ * glStencilFuncSeparate(GLenum face, GLenum func, ...).

+ *

+ * This problem is solved by keeping three sets of stencil state:

- * The GL texture image functions in teximage.c basically just do
- * error checking and data structure allocation.  They in turn call
- * device driver functions which actually copy/convert/store the user's
- * texture image data.
- *
- * However, most device drivers will be able to use the fallback functions
- * in this file.  That is, most drivers will have the following bit of
- * code:
- *   ctx->Driver.TexImage1D = _mesa_store_teximage1d;
- *   ctx->Driver.TexImage2D = _mesa_store_teximage2d;
- *   ctx->Driver.TexImage3D = _mesa_store_teximage3d;
- *   etc...
- *
- * Texture image processing is actually kind of complicated.  We have to do:
- *    Format/type conversions
- *    pixel unpacking
- *    pixel transfer (scale, bais, lookup, etc)
- *
- * These functions can handle most everything, including processing full
- * images and sub-images.

+ * The GL texture image functions in teximage.c basically just do

+ * device driver functions which actually copy/convert/store the user's

+ * texture image data.

+ *

+ * However, most device drivers will be able to use the fallback functions

+ * in this file.  That is, most drivers will have the following bit of

+ * code:

+ *   ctx->Driver.TexImage1D = _mesa_store_teximage1d;

+ *   ctx->Driver.TexImage2D = _mesa_store_teximage2d;

+ *   ctx->Driver.TexImage3D = _mesa_store_teximage3d;

+ *   etc...

+ *

+ * Texture image processing is actually kind of complicated.  We have to do:

+ *    Format/type conversions

+ *    pixel unpacking

+ *    pixel transfer (scale, bais, lookup, etc)

+ *

+ * These functions can handle most everything, including processing full

- * GLGL uniform arrays and structs require special handling.
- *
- * The GL_ARB_shader_objects spec says that if you use
- * glGetUniformLocation to get the location of an array, you CANNOT
- * access other elements of the array by adding an offset to the
- * returned location.  For example, you must call
- * glGetUniformLocation("foo[16]") if you want to set the 16th element
- * of the array with glUniform().
- *
- * HOWEVER, some other OpenGL drivers allow accessing array elements
- * by adding an offset to the returned array location.  And some apps
- * seem to depend on that behaviour.
- *
- * Mesa's gl_uniform_list doesn't directly support this since each
- * entry in the list describes one uniform variable, not one uniform
- * element.  We could insert dummy entries in the list for each array
- * element after [0] but that causes complications elsewhere.
- *
- * We solve this problem by encoding two values in the location that's
- * returned by glGetUniformLocation():
- *  a) index into gl_uniform_list::Uniforms[] for the uniform
- *  b) an array/field offset (0 for simple types)
- *
- * These two values are encoded in the high and low halves of a GLint.
- * By putting the uniform number in the high part and the offset in the
- * low part, we can support the unofficial ability to index into arrays
- * by adding offsets to the location value.

+ * access other elements of the array by adding an offset to the

+ * returned location.  For example, you must call

+ * glGetUniformLocation("foo[16]") if you want to set the 16th element

+ * of the array with glUniform().

+ *

+ * HOWEVER, some other OpenGL drivers allow accessing array elements

+ * by adding an offset to the returned array location.  And some apps

+ * seem to depend on that behaviour.

+ *

+ * Mesa's gl_uniform_list doesn't directly support this since each

+ * entry in the list describes one uniform variable, not one uniform

+ * element.  We could insert dummy entries in the list for each array

+ * element after [0] but that causes complications elsewhere.

+ *

+ * We solve this problem by encoding two values in the location that's

+ * returned by glGetUniformLocation():

+ *  a) index into gl_uniform_list::Uniforms[] for the uniform

+ *  b) an array/field offset (0 for simple types)

+ *

+ * These two values are encoded in the high and low halves of a GLint.

+ * By putting the uniform number in the high part and the offset in the

+ * low part, we can support the unofficial ability to index into arrays

+ * by adding offsets to the location value.

-The instructions we emit will use six kinds of source registers:

-  PROGRAM_INPUT      - input registers
-  PROGRAM_TEMPORARY  - temp registers
-  PROGRAM_ADDRESS    - address/indirect register
-  PROGRAM_SAMPLER    - texture sampler
-  PROGRAM_CONSTANT   - indexes into program->Parameters, a known constant/literal
-  PROGRAM_STATE_VAR  - indexes into program->Parameters, and may actually be:
-                       + a state variable, like "state.fog.color", or
-                       + a pointer to a "program.local[k]" parameter, or
-                       + a pointer to a "program.env[k]" parameter
-
-Basically, all the program.local[] and program.env[] values will get mapped
-into the unified gl_program->Parameters array.  This solves the problem of
-having three separate program parameter arrays.

+Notes on program parameters, etc.

+

+The instructions we emit will use six kinds of source registers:

+

+  PROGRAM_INPUT      - input registers

+  PROGRAM_TEMPORARY  - temp registers

+  PROGRAM_ADDRESS    - address/indirect register

+  PROGRAM_SAMPLER    - texture sampler

+  PROGRAM_CONSTANT   - indexes into program->Parameters, a known constant/literal

+  PROGRAM_STATE_VAR  - indexes into program->Parameters, and may actually be:

+                       + a state variable, like "state.fog.color", or

+                       + a pointer to a "program.local[k]" parameter, or

+                       + a pointer to a "program.env[k]" parameter

+

+Basically, all the program.local[] and program.env[] values will get mapped

+into the unified gl_program->Parameters array.  This solves the problem of

+having three separate program parameter arrays.

- * Accumulation buffer notes
- *
- * Normally, accumulation buffer values are GLshorts with values in
- * [-32767, 32767] which represent floating point colors in [-1, 1],
- * as defined by the OpenGL specification.
- *
- * We optimize for the common case used for full-scene antialiasing:
- *    // start with accum buffer cleared to zero
- *    glAccum(GL_LOAD, w);   // or GL_ACCUM the first image
- *    glAccum(GL_ACCUM, w);
- *    ...
- *    glAccum(GL_ACCUM, w);
- *    glAccum(GL_RETURN, 1.0);
- * That is, we start with an empty accumulation buffer and accumulate
- * n images, each with weight w = 1/n.
- * In this scenario, we can simply store unscaled integer values in
- * the accum buffer instead of scaled integers.  We'll also keep track
- * of the w value so when we do GL_RETURN we simply divide the accumulated
- * values by n (n=1/w).
- * This lets us avoid _many_ int->float->int conversions.

+ * Accumulation buffer notes

+ * Normally, accumulation buffer values are GLshorts with values in

+ * as defined by the OpenGL specification.

+ *

+ * We optimize for the common case used for full-scene antialiasing:

+ *    // start with accum buffer cleared to zero

+ *    glAccum(GL_LOAD, w);   // or GL_ACCUM the first image

+ *    glAccum(GL_ACCUM, w);

+ *    ...

+ *    glAccum(GL_ACCUM, w);

+ *    glAccum(GL_RETURN, 1.0);

+ * That is, we start with an empty accumulation buffer and accumulate

+ * n images, each with weight w = 1/n.

+ * In this scenario, we can simply store unscaled integer values in

+ * the accum buffer instead of scaled integers.  We'll also keep track

+ * of the w value so when we do GL_RETURN we simply divide the accumulated

+ * values by n (n=1/w).

+ * This lets us avoid _many_ int->float->int conversions.

-/* Display list compiler attempts to store lists of vertices with the
- * same vertex layout.  Additionally it attempts to minimize the need
- * for execute-time fixup of these vertex lists, allowing them to be
- * cached on hardware.
- *
- * There are still some circumstances where this can be thwarted, for
- * example by building a list that consists of one very long primitive
- * (eg Begin(Triangles), 1000 vertices, End), and calling that list
- * from inside a different begin/end object (Begin(Lines), CallList,
- * End).  
- *
- * In that case the code will have to replay the list as individual
- * commands through the Exec dispatch table, or fix up the copied
- * vertices at execute-time.
- *
- * The other case where fixup is required is when a vertex attribute
- * is introduced in the middle of a primitive.  Eg:
- *  Begin(Lines)
- *  TexCoord1f()           Vertex2f()
- *  TexCoord1f() Color3f() Vertex2f()
- *  End()
- *
- *  If the current value of Color isn't known at compile-time, this
- *  primitive will require fixup.
- *
- *
- * The list compiler currently doesn't attempt to compile lists
- * containing EvalCoord or EvalPoint commands.  On encountering one of
- * these, compilation falls back to opcodes.  
- *
- * This could be improved to fallback only when a mix of EvalCoord and
- * Vertex commands are issued within a single primitive.

+/* Display list compiler attempts to store lists of vertices with the

+ * same vertex layout.  Additionally it attempts to minimize the need

+ * for execute-time fixup of these vertex lists, allowing them to be

+ * cached on hardware.

+ *

+ * There are still some circumstances where this can be thwarted, for

+ * example by building a list that consists of one very long primitive

+ * (eg Begin(Triangles), 1000 vertices, End), and calling that list

+ * from inside a different begin/end object (Begin(Lines), CallList,

+ * End).  

+ *

+ * In that case the code will have to replay the list as individual

+ * commands through the Exec dispatch table, or fix up the copied

+ * vertices at execute-time.

+ *

+ * The other case where fixup is required is when a vertex attribute

+ * is introduced in the middle of a primitive.  Eg:

+ *  Begin(Lines)

+ *  TexCoord1f()           Vertex2f()

+ *  TexCoord1f() Color3f() Vertex2f()

+ *  End()

+ *

+ *  If the current value of Color isn't known at compile-time, this

+ *  primitive will require fixup.

+ *

+ *

+ * The list compiler currently doesn't attempt to compile lists

+ * containing EvalCoord or EvalPoint commands.  On encountering one of

+ * these, compilation falls back to opcodes.  

+ *

+ * This could be improved to fallback only when a mix of EvalCoord and

+ * Vertex commands are issued within a single primitive.
