* mesa: change glTexImage[23]DMultisample() internalformat to GLenumBrian Paul2013-10-162-4/+4

* mesa: consolidate cube width=height error checkingBrian Paul2013-10-161-38/+5
| | | | | | | | | | | | | | | Instead of checking width==height in four places, just do it in _mesa_legal_texture_dimensions() where we do the other width, height, depth checks. Similarly, move the check that cube map array depth is a multiple of 6. This change also fixes some missing cube dimension checks for the glTexStorage[23]D() functions. Remove width==height assertion in _mesa_get_tex_max_num_levels() since that's called before the other size checks for glTexStorage. Cc: "9.2" <[email protected]>
* mesa: fix transform feedback when a geometry shader is active.Bryan Cain2013-10-151-18/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a geometry shader is active, the transform feedback primitive type ("mode") needs to be validated against the geometry shader output primitive type, not the primitive type passed to the glDraw*() function. Fixes the following piglit tests: - glsl-1.50-geometry-primitive-types GL_LINES - glsl-1.50-geometry-primitive-types GL_LINES_ADJACENCY - glsl-1.50-geometry-primitive-types GL_LINE_STRIP - glsl-1.50-geometry-primitive-types GL_LINE_STRIP_ADJACENCY - glsl-1.50-geometry-primitive-types GL_TRIANGLES - glsl-1.50-geometry-primitive-types GL_TRIANGLES_ADJACENCY - glsl-1.50-geometry-primitive-types GL_TRIANGLE_FAN Exposes previously hidden failures in the following piglit tests: - glsl-1.50-geometry-primitive-id-restart GL_LINES other - glsl-1.50-geometry-primitive-id-restart GL_LINES_ADJACENCY other - glsl-1.50-geometry-primitive-id-restart GL_LINE_LOOP ffs - glsl-1.50-geometry-primitive-id-restart GL_LINE_LOOP other - glsl-1.50-geometry-primitive-id-restart GL_LINE_STRIP other - glsl-1.50-geometry-primitive-id-restart GL_LINE_STRIP_ADJACENCY other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLES other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLES_ADJACENCY other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_FAN ffs - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_FAN other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_STRIP other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_STRIP_ADJACENCY other (These failures were previously hidden due to a flaw in the test: it doesn't check for GL errors.

| | | | | | | | | | | | | | | | | These make it easy to convert a floating point value to a fixed point numbers. The second parameter is the number of bits used for the fractional part of the number. It looks like core Mesa has similar functions already, but none that allows an arbitrary number of fractional bits. The more generic version is probably useful to everyone. r600g apparently has an identical copy of the S_FIXED macro, but doesn't include this file.

* mesa: Allow external textures to use fallback (0, 0, 0, 1)Topi Pohjolainen2013-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes GL2ExtensionTests/egl_image_external/TestSimpleUnassociated.test which is part of gles2/3 conformance suite. Here image external textures are switched to be treated the same as 2D textures. These can be associated with the fallback texture providing fixed sample values of (0, 0, 0, 1). The OES_EGL_image_external spec says: "Sampling an external texture which is not associated with any EGLImage sibling will return a sample value of (0,0,0,1)." "External textures cannot be used with TexImage2D, TexSubImage2D, CompressedTexImage2D, CompressedTexSubImage2D, CopyTexImage2D, or CopyTexSubImage2D, and an INVALID_ENUM error will be generated if this is attempted." And quoting Chad: "That's enforced in _mesa_TexImage*() by calling legal_teximage_target(), and enforced in _mesa_TexSubImage*() by calling legal_texsubmimage_target(). Each of the legal_tex*image_target() functions reject external textures. Therefore, allowing GL_TEXTURE_EXTERNAL_OES in store_texsubimage() won't violate the above spec quote. I think it's safe to allow GL_TEXTURE_EXTERNAL_OES in store_texsubimage(), as long as the texture has only a single plane. Luckily, that's the only type of external textures that Mesa currently supports."

* mesa: Add core support for the GL_AMD_performance_monitor extension.Kenneth Graunke2013-09-267-0/+820
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides an interface for applications (and OpenGL-based tools) to access GPU performance counters. Since the exact performance counters available vary between vendors and hardware generations, the extension provides an API the application can use to get the names, types, and minimum/maximum values of all available counters. Counters are also organized into groups. Applications create "performance monitor" objects, select the counters they want to track, and Begin/End monitoring, much like OpenGL's query API. Multiple monitors can be in flight simultaneously. v2: Pass ctx to all driver hooks (suggested by Christoph), and attempt to fix overallocation of bitsets (caught by Christoph). Incomplete. v3: Significantly rework core data structures. Store counters in groups rather than in a global list. Use their array index in the group's counter list as the ID rather than trying to store a globally unique counter ID. Use bitsets for active counters within a group, and also track which groups are active so that's easy to query. v4: Remove _mesa_ prefix on static functions; detect out of memory conditions in new_performance_monitor(); make BeginPerfMonitor hook return a boolean rather than setting m->Active or raising an error. Switch to GLuint/unsigned for NumGroups, NumCounters, and MaxActiveCounters (which also means switching a bunch of temporary variable types). All suggested by Brian Paul. Also, remove commented out code at the bottom of the block. Finally, fix the dispatch sanity test (noticed by Ian Romanick).
