| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | OpenGL 4.2 specification suggests rounding the float data to nearest integer when the type of internal state is integer. Out of range floats should be clamped to {INT_MIN, INT_MAX}. This is not specified anywhere in gl/gles spec but below test expects this behavior. This patch makes gles3 conformance sgis_texture_lod_basic_getter.test pass. A GL spec bug will be raised to include clamping of out of range floats. V2: Round float to nearest integer for all cases where _mesa_Texparameterf() converts float param to int.

| | | | | | | | | | | | | | | | | | | | | In ES 3.0, when calling glDrawBuffers() on the window system framebuffer, the only valid targets are GL_NONE or GL_BACK. Since there is no stereo rendering in ES 3.0, this is a single buffer, unlike desktop where it may be two (and thus isn't allowed). For single-buffered configs, GL_BACK ironically means the front (and only) buffer. I'm not sure that it matters, however, as ES shouldn't have front buffer rendering in the first place.

* mesa: Fix default value of BUFFER_ACCESS_FLAGS.Kenneth Graunke2013-01-151-28/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | Perhaps most importantly, this patch adds comments quoting the relevant spec paragraphs above each error condition. It also makes three changes: - For FBOs, GL_COLOR_ATTACHMENTm where m >= MaxDrawBuffers is supposed to generate INVALID_OPERATION (not INVALID_ENUM). - Constants that refer to multiple buffers (such as FRONT, BACK, LEFT, RIGHT, and FRONT_AND_BACK) are supposed to generate INVALID_OPERATION, not INVALID_ENUM. - In ES 3.0, for FBOs, buffers[i] must be NONE or GL_COLOR_ATTACHMENTi or else INVALID_OPERATION occurs. (This is a new restriction.) Fixes es3conform's draw-buffers-api test. v2: The error path was missing a "return" like all the other error paths. Also, we may as well call it glDrawBuffers in the error message since the ARB suffix doesn't exist in ES 3.
