* mesa: Array uniform name length includes length of [0]Ian Romanick2013-01-181-0/+10
| | | | | | | | | | | | | This is required by OpenGL ES 3.0 and desktop OpenGL 4.2. Previous version were ambiguous. This also matches the behavior of NVIDIA's closed-source driver (version 304.64).

* intel: Make intel_region's pitch be bytes instead of pixels.Eric Anholt2013-01-1821-77/+67
| | | | | | | | | | | | We almost never want a stride in pixels -- if you're doing anything with a stride, you're specifying an offset or incrementing a pointer, and in both cases you had to multiply by cpp to get the bytes value you wanted. But worse, on the way to creating a region from a new tiled BO, we divided by cpp to get pitch in pixels, and for an RGB32 buffer (an upcoming change) the pitch wouldn't divide exactly, and we'd end up with a wrong stride in our region.

* mesa: Only mark textures as mipmap incomplete on MAX_LEVEL issues.Kenneth Graunke2013-01-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the OpenGL 3.2 Core Profile specification, section 3.8.12: "For one-, two-, and three-dimensional and one-and two-dimensional array textures, a texture is mipmap complete if all of the following conditions hold true: - [...] - levelbase <= levelmax [...] Using the preceding definitions, a texture is complete unless any of the following conditions hold true: - [...] - The minification filter requires a mipmap (is neither NEAREST nor LINEAR), and the texture is not mipmap complete." (This text also appears in all GL >= 3.2 specs and the ES 3.0 spec.) From this, we see that levelbase <= levelmax should only affect mipmap completeness, not base-level completeness. Prior versions of GL did not have the notion of mipmap completeness, simply calling the texture incomplete in this case. But I don't think we really care.

It appears that every EGLConfig on i830 has EGL_RENDERABLE_TYPE=0, and thus eglCreateContext will never succeed. Anyway, moving on to living drivers... With the arrival of EGL_OPENGL_ES3_BIT_KHR, this heuristic is now insufficient. We must enable the GLES3 bit if and only if the driver is capable of creating a GLES3 context. This requires us to determine the maximum supported context version supported by the hardware/driver for each api *during initialization of intel_screen*. Therefore, this patch adds four new fields to intel_screen which indicate the maximum supported context version for each api: max_gl_core_version max_gl_compat_version max_gl_es1_version max_gl_es2_version The api mask is now correctly set as: api_mask = GL; if (max_gl_es1_version > 0) api_mask |= GLES1; if (max_gl_es2_version > 0) api_mask |= GLES2; Tested against gen6 with piglit egl-create-context-verify-gl-flavor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to both the GL 3.0 and ES 3.0 specifications (table 2.7 for GL and table 2.8 for ES), the default value of BUFFER_ACCESS_FLAGS is supposed to be zero. Note that there are two related quantities: the obsolete BUFFER_ACCESS enum and the new BUFFER_ACCESS_FLAGS bitfield. BUFFER_ACCESS can only be GL_READ_ONLY, GL_WRITE_ONLY, or GL_READ_WRITE; BUFFER_ACCESS_FLAGS can easily represent all three via GL_MAP_WRITE_BIT, GL_MAP_READ_BIT, and their logical or. It also supports more flags. Thus, Mesa only stores the bitfield, and simply computes the old enum when queried, via simplified_access_mode(bufObj->AccessFlags). The tricky part is that, while BUFFER_ACCESS_FLAGS defaults to 0, BUFFER_ACCESS defaults to GL_READ_WRITE for desktop [GL 3.0, table 2.8] and GL_WRITE_ONLY_OES for ES [the GL_EXT_map_buffer_range extension]. Mesa tried to implement this by setting the default AccessFlags to GL_MAP_READ_BIT | GL_MAP_WRITE_BIT on desktop, and GL_MAP_WRITE_BIT on ES. But in all specifications, it needs to be 0. This patch moves that logic into simplified_access_mode(): when AccessFlags == 0, it now returns GL_READ_WRITE for desktop and GL_WRITE_ONLY for ES 1/2. (BUFFER_ACCESS doesn't exist on ES 3.0, so it's irrelevant there.) With that in place, it changes the AccessFlags default to 0.
