[Piglit] [PATCH 1/4] program_interface_query: add tests for querying the resources
Martin Peres
martin.peres at linux.intel.com
Wed Mar 25 09:01:29 PDT 2015
This tests primarily glGetProgramInterfaceiv in various (potentially
tricky) program pipelines. All the calls are supposed to succeed as
this test is purely functional.
This test requires a OpenGL 3.2 core context but also has optional
subtests that depend on the following extensions:
- GL_ARB_shader_atomic_counters
- GL_ARB_shader_storage_buffer_object
- GL_ARB_shader_subroutine
- GL_ARB_tessellation_shader
- GL_ARB_compute_shader
- GL_ARB_shader_image_load_store

+ * Tests querying resources.
+ *
+ * From the GL_ARB_program_interface_query spec:
+ * "The command
+ *
+ * void GetProgramInterfaceiv(uint program, enum programInterface,
+ * enum pname, int *params);
+ *
+ * queries a property of the interface <programInterface> in program
+ * <program>, returning its value in <params>. The property to return is
+ * specified by <pname>.
+ *
+ * If <pname> is ACTIVE_RESOURCES, the value returned is the number of
+ * resources in the active resource list for <programInterface>. If the
+ * list of active resources for <programInterface> is empty, zero is
+ * returned.
+ *
+ * If <pname> is MAX_NAME_LENGTH, the value returned is the length of the
+ * longest active name string for an active resource in <programInterface>.
+ * This length includes an extra character for the null terminator. If
+ * the list of active resources for <programInterface> is empty, zero is
+ * returned. The error INVALID_OPERATION is generated if
+ * <programInterface> is ATOMIC_COUNTER_BUFFER, since active atomic counter
+ * buffer resources are not assigned name strings.
+ *
+ * If <pname> is MAX_NUM_ACTIVE_VARIABLES, the value returned is the number
+ * of active variables belonging to the interface block or atomic counter
+ * buffer resource in <programInterface> with the most active variables.
+ * If the list of active resources for <programInterface> is empty, zero is
+ * returned. The error INVALID_OPERATION is generated if
+ * <programInterface> is not UNIFORM_BLOCK, ATOMIC_COUNTER_BUFFER, or
+ * SHADER_STORAGE_BLOCK.
+ *
+ * If <pname> is MAX_NUM_COMPATIBLE_SUBROUTINES, the value returned is the
+ * number of compatible subroutines belonging to the active subroutine
+ * uniform in <programInterface> with the most compatible subroutines. If
+ * the list of active resources for <programInterface> is empty, zero is
+ * returned. The error INVALID_OPERATION is generated unless
+ * <programInterface> is VERTEX_SUBROUTINE_UNIFORM,
+ * TESS_CONTROL_SUBROUTINE_UNIFORM, TESS_EVALUATION_SUBROUTINE_UNIFORM,
+ * GEOMETRY_SUBROUTINE_UNIFORM, FRAGMENT_SUBROUTINE_UNIFORM, or
+ * COMPUTE_SUBROUTINE_UNIFORM.
+ *
+ * The command
+ *
+ * uint GetProgramResourceIndex(uint program, enum programInterface,
+ * const char *name);
+ *
+ * returns the unsigned integer index assigned to a resource named <name>
+ * in the interface type <programInterface> of program object <program>.
+ * The error INVALID_ENUM is generated if <programInterface> is
+ * ATOMIC_COUNTER_BUFFER, since active atomic counter buffer resources are
+ * not assigned name strings.
+ *
+ * If <name> exactly matches the name string of one of the active resources
+ * for <programInterface>, the index of the matched resource is returned.
+ * Additionally, if <name> would exactly match the name string of an active
+ * resource if "[0]" were appended to <name>, the index of the matched
+ * resource is returned. Otherwise, <name> is considered not to be the
+ * name of an active resource, and INVALID_INDEX is returned. Note that if
+ * an interface enumerates a single active resource list entry for an array
+ * variable (e.g., "a[0]"), a <name> identifying any array element other
+ * than the first (e.g., "a[1]") is not considered to match.
+ *
+ * For the interface TRANSFORM_FEEDBACK_VARYING, the value INVALID_INDEX
+ * should be returned when querying the index assigned to the special names
+ * "gl_NextBuffer", "gl_SkipComponents1", "gl_SkipComponents2",
+ * "gl_SkipComponents3", and "gl_SkipComponents4".
+ *
+ * The command
+ *
+ * void GetProgramResourceName(uint program, enum programInterface,
+ * uint index, sizei bufSize, sizei *length,
+ * char *name);
+ *
+ * returns the name string assigned to the single active resource with an
+ * index of <index> in the interface <programInterface> of program object
+ * <program>. The error INVALID_VALUE is generated if <index> is greater
+ * than or equal to the number of entries in the active resource list for
+ * <programInterface>. The error INVALID_ENUM is generated if
+ * <programInterface> is ATOMIC_COUNTER_BUFFER, since active atomic counter
+ * buffer resources are not assigned name strings.
+ *
+ * The name string assigned to the active resource identified by <index> is
+ * returned as a null-terminated string in <name>. The actual number of
+ * characters written into <name>, excluding the null terminator, is
+ * returned in <length>. If <length> is NULL, no length is returned. The
+ * maximum number of characters that may be written into <name>, including
+ * the null terminator, is specified by <bufSize>. If the length of the
+ * name string (including the null terminator) is greater than <bufSize>,
+ * the first <bufSize>-1 characters of the name string will be written to
+ * <name>, followed by a null terminator. If <bufSize> is zero, no error
+ * will be generated but no characters will be written to <name>. The
+ * length of the longest name string for <programInterface>, including a
+ * null terminator, can be queried by calling GetProgramInterfaceiv with a
+ * <pname> of MAX_NAME_LENGTH.

+/* Naming conventions, from the GL_ARB_program_interface_query extension:
+ *
+ * "When building a list of active variable or interface blocks, resources
+ * with aggregate types (such as arrays or structures) may produce multiple
+ * entries in the active resource list for the corresponding interface.
+ * Additionally, each active variable, interface block, or subroutine in the
+ * list is assigned an associated name string that can be used by
+ * applications to refer to the resources. For interfaces involving
+ * variables, interface blocks, or subroutines, the entries of active
+ * resource lists are generated as follows:
+ *
+ * * For an active variable declared as a single instance of a basic type,
+ * a single entry will be generated, using the variable name from the
+ * shader source.
+ *
+ * * For an active variable declared as an array of basic types, a single
+ * entry will be generated, with its name string formed by concatenating
+ * the name of the array and the string "[0]".
+ *
+ * * For an active variable declared as a structure, a separate entry will
+ * be generated for each active structure member. The name of each entry
+ * is formed by concatenating the name of the structure, the "."
+ * character, and the name of the structure member. If a structure
+ * member to enumerate is itself a structure or array, these enumeration
+ * rules are applied recursively.
+ *
+ * * For an active variable declared as an array of an aggregate data type
+ * (structures or arrays), a separate entry will be generated for each
+ * active array element, unless noted immediately below. The name of
+ * each entry is formed by concatenating the name of the array, the "["
+ * character, an integer identifying the element number, and the "]"
+ * character. These enumeration rules are applied recursively, treating
+ * each enumerated array element as a separate active variable.
+ *
+ * * For an active shader storage block member declared as an array, an
+ * entry will be generated only for the first array element, regardless
+ * of its type. For arrays of aggregate types, the enumeration rules are
+ * applied recursively for the single enumerated array element.
+ *
+ * * For an active interface block not declared as an array of block
+ * instances, a single entry will be generated, using the block name from
+ * the shader source.
+ *
+ * * For an active interface block declared as an array of instances,
+ * separate entries will be generated for each active instance. The name
+ * of the instance is formed by concatenating the block name, the "["
+ * character, an integer identifying the instance number, and the "]"
+ * character.
+ *
+ * * For an active subroutine, a single entry will be generated, using the
+ * subroutine name from the shader source.
+ *
+ * When an integer array element or block instance number is part of the name
+ * string, it will be specified in decimal form without a "+" or "-" sign or
+ * any extra leading zeroes. Additionally, the name string will not include
+ * white space anywhere in the string.
