[Piglit] [PATCH v6 6/6] program_interface_query: add tests for getprogramresourceiv
Martin Peres
martin.peres at linux.intel.com
Thu Apr 2 05:06:18 PDT 2015
Tested on NVIDIA's proprietary driver version 346.35.
v2:
- test GL_ATOMIC_COUNTER_BUFFER (hackish since indexes are hardcoded)
- cosmetic changes in a switch
- fix a typo: inconsitent -> inconsistent
- require GL_ARB_separate_shader_objects
- compile some programs as separable

+ * \file getprogramresourceiv.c
+ *
+ * Tests the values returned by GetProgramResourceiv on multiple pipelines.
+ * Also checks some error cases.
+ *
+ * From the GL_ARB_program_interface_query spec:
+ * "The command
+ *
+ * void GetProgramResourceiv(uint program, enum programInterface,
+ * uint index, sizei propCount,
+ * const enum *props, sizei bufSize,
+ * sizei *length, int *params);
+ *
+ * returns values for multiple properties of a single active resource with an
+ * index of <index> in the interface <programInterface> of program object
+ * <program>. For each resource, values for <propCount> properties specified
+ * by the array <props> are returned. The error INVALID_VALUE is generated
+ * if <propCount> is zero. The error INVALID_ENUM is generated if any value
+ * in <props> is not one of the properties described immediately below. The
+ * error INVALID_OPERATION is generated if any value in <props> is not
+ * allowed for <programInterface>. The set of allowed <programInterface>
+ * values for each property can be found in Table X.1.
+
+ * The values associated with the properties of the active resource are
+ * written to consecutive entries in <params>, in increasing order according
+ * to position in <props>. If no error is generated, only the first
+ * <bufSize> integer values will be written to <params>; any extra values
+ * will not be returned. If <length> is not NULL, the actual number of
+ * integer values written to <params> will be written to <length>.

+ * For the property NAME_LENGTH, a single integer identifying the length of
+ * the name string associated with an active variable, interface block, or
+ * subroutine is written to <params>. The name length includes a terminating
+ * null character.
+ *
+ * For the property TYPE, a single integer identifying the type of an active
+ * variable is written to <params>. The integer returned is one of the
+ * values found in table 2.16.
+ *
+ * For the property ARRAY_SIZE, a single integer identifying the number of
+ * active array elements of an active variable is written to <params>. The
+ * array size returned is in units of the type associated with the property
+ * TYPE. For active variables not corresponding to an array of basic types,
+ * the value one is written to <params>. If the variable is a shader
+ * storage block member in an array with no declared size, the value zero
+ * is written to <params>.
+ *
+ * For the property BLOCK_INDEX, a single integer identifying the index of
+ * the active interface block containing an active variable is written to
+ * <params>. If the variable is not the member of an interface block, the
+ * value -1 is written to <params>.
+ *
+ * For the property OFFSET, a single integer identifying the offset of an
+ * active variable is written to <params>. For active variables backed by a
+ * buffer object, the value written is the offset, in basic machine units,
+ * relative to the base of buffer range holding the values of the variable.
+ * For active variables not backed by a buffer object, an offset of -1 is
+ * written to <params>.
+ *
+ * For the property ARRAY_STRIDE, a single integer identifying the stride
+ * between array elements in an active variable is written to <params>. For
+ * active variables declared as an array of basic types, the value written is
+ * the difference, in basic machine units, between the offsets of consecutive
+ * elements in an array. For active variables not declared as an array of
+ * basic types, zero is written to <params>. For active variables not backed
+ * by a buffer object, -1 is written to <params>, regardless of the variable
+ * type.
+ *
+ * For the property MATRIX_STRIDE, a single integer identifying the stride
+ * between columns of a column-major matrix or rows of a row-major matrix is
+ * written to <params>. For active variables declared a single matrix or
+ * array of matrices, the value written is the difference, in basic machine
+ * units, between the offsets of consecutive columns or rows in each matrix.
+ * For active variables not declared as a matrix or array of matrices, zero
+ * is written to <params>. For active variables not backed by a buffer
+ * object, -1 is written to <params>, regardless of the variable type.
+ *
+ * For the property IS_ROW_MAJOR, a single integer identifying whether an
+ * active variable is a row-major matrix is written to <params>. For active
+ * variables backed by a buffer object, declared as a single matrix or array
+ * of matrices, and stored in row-major order, one is written to <params>.
+ * For all other active variables, zero is written to <params>.
+ *
+ * For the property ATOMIC_COUNTER_BUFFER_INDEX, a single integer identifying
+ * the index of the active atomic counter buffer containing an active
+ * variable is written to <params>. If the variable is not an atomic counter
+ * uniform, the value -1 is written to <params>.
+ *
+ * For the property of BUFFER_BINDING, to index of the buffer binding point
+ * associated with the active uniform block, shader storage block, or atomic
+ * counter buffer is written to <params>.
+ *
+ * For the property of BUFFER_DATA_SIZE, then the implementation-dependent
+ * minimum total buffer object size, in basic machine units, required to hold
+ * all active variables associated with an active uniform block, shader
+ * storage block, or atomic counter buffer is written to <params>. If the
+ * final member of an active shader storage block is array with no declared
+ * size, the minimum buffer size is computed assuming the array was declared
+ * as an array with one element.
+ *
+ * For the property of NUM_ACTIVE_VARIABLES, the number of active variables
+ * associated with an active uniform block, shader storage block, or atomic
+ * counter buffer is written to <params>.
+ *
+ * For the property of ACTIVE_VARIABLES, an array of active variable indices
+ * associated with an active uniform block, shader storage block, or atomic
+ * counter buffer is written to <params>. The number of values written to
+ * <params> for an active resource is given by the value of the property
+ * NUM_ACTIVE_VARIABLES for the resource.
+ *
+ * For the properties REFERENCED_BY_VERTEX_SHADER,
+ * REFERENCED_BY_TESS_CONTROL_SHADER, REFERENCED_BY_TESS_EVALUATION_SHADER,
+ * REFERENCED_BY_GEOMETRY_SHADER, REFERENCED_BY_FRAGMENT_SHADER, and
+ * REFERENCED_BY_COMPUTE_SHADER, a single integer is written to <params>,
+ * identifying whether the active resource is referenced by the vertex,
+ * tessellation control, tessellation evaluation, geometry, or fragment
+ * shaders, respectively, in the program object. The value one is written to
+ * <params> if an active variable is referenced by the corresponding shader,
+ * or if an active uniform block, shader storage block, or atomic counter
+ * buffer contains at least one variable referenced by the corresponding
+ * shader. Otherwise, the value zero is written to <params>.
+ *
+ * For the property TOP_LEVEL_ARRAY_SIZE, a single integer identifying the
+ * number of active array elements of the top-level shader storage block
+ * member containing to the active variable is written to <params>. If the
+ * top-level block member is not declared as an array, the value one is
+ * written to <params>. If the top-level block member is an array with no
+ * declared size, the value zero is written to <params>.
+ *
+ * For the property TOP_LEVEL_ARRAY_STRIDE, a single integer identifying the
+ * stride between array elements of the top-level shader storage block member
+ * containing the active variable is written to <params>. For top-level
+ * block members declared as arrays, the value written is the difference, in
+ * basic machine units, between the offsets of the active variable for
+ * consecutive elements in the top-level array. For top-level block members
+ * not declared as an array, zero is written to <params>.
+ *
+ * For the property LOCATION, a single integer identifying the assigned
+ * location for an active uniform, input, output, or subroutine uniform
+ * variable is written to <params>. For input, output, or uniform variables
+ * with locations specified by a layout qualifier, the specified location is
+ * used. For vertex shader input or fragment shader output variables without
+ * a layout qualifier, the location assigned when a program is linked is
+ * written to <params>. For all other input and output variables, the value
+ * -1 is written to <params>. For uniforms in uniform blocks, the value -1
+ * is written to <params>.
+ *
+ * For the property LOCATION_INDEX, a single integer identifying the fragment
+ * color index of an active fragment shader output variable is written to
+ * <params>. If the active variable is an output for a non-fragment shader,
+ * the value -1 will be written to <params>.
+ *
+ * For the property IS_PER_PATCH, a single integer identifying whether the
+ * input or output is a per-patch attribute. If the active variable is a
+ * per-patch attribute (declared with the "patch" qualifier), the value one
+ * is written to <params>; otherwise, the value zero is written to <params>."
