* libgl-gdi: Avoid hangs on DLL_PROCESS_DETACH.Rob Schneider2013-01-151-2/+4
| | | | | | | | | | | | At process exit DLL_PROCESS_DETACH is signaled to DllMain(), where then a final cleanup is triggered. In stw_cleanup() code is triggered that tries to communicate a shutdown to the spawned threads -- however at that time those threads have already been terminated by the OS and so the process hangs. v2: skip stw_cleanup_thread() too Signed-off-by: José Fonseca <[email protected]>
* egl/dri2: Add plumbing for EGL_OPENGL_ES3_BIT_KHRChad Versace2013-01-156-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes error EGL_BAD_ATTRIBUTE in the tests below on Intel Sandybridge: * piglit egl-create-context-verify-gl-flavor, testcase OpenGL ES 3.0 * gles3conform, revision 19700, when runnning GL3Tests with -fbo This plumbing is added in order to comply with the EGL_KHR_create_context spec. According to the EGL_KHR_create_context spec, it is illegal to call eglCreateContext(EGL_CONTEXT_MAJOR_VERSION_KHR=3) with a config whose EGL_RENDERABLE_TYPE does not contain the EGL_OPENGL_ES3_BIT_KHR. The pertinent portion of the spec is quoted below; the key word is "respectively". * If <config> is not a valid EGLConfig, or does not support the requested client API, then an EGL_BAD_CONFIG error is generated (this includes requesting creation of an OpenGL ES 1.x, 2.0, or 3.0 context when the EGL_RENDERABLE_TYPE attribute of <config> does not contain EGL_OPENGL_ES_BIT, EGL_OPENGL_ES2_BIT, or EGL_OPENGL_ES3_BIT_KHR respectively). To create this patch, I searched for all the ES2 bit plumbing by calling `git grep "ES2_BIT\|DRI_API_GLES2" src/egl`, and then at each location added a case for ES3.

I'd prefer that all GLES APIs be exposed through a single API bit, as is done in GLX_EXT_create_context_es_profile. But, we need this GLES3 enum in order to do the plumbing necessary to correctly support EGL_OPENGL_ES3_BIT_KHR as required by the EGL_KHR_create_context spec.

* intel: Move validation of context version into intelInitContextChad Versace2013-01-157-105/+100
| | | | | | | | | | | | | | | | | | | | | Each driver (i830, i915, i965) used independent but similar code to validate the requested context version. With the rececnt arrival of GLES3, that logic has needed an update. Rather than apply identical updates to each drivers validation code, let's just move the validation into the shared routine intelInitContext. This refactor required some incidental changes to functions i830CreateContext and intelInitContext. For each function, this patch: - Adds context version parameters to the signature. - Adds a DRI_CTX_ERROR out param to the signature. - Sets the DRI_CTX_ERROR at each early return. Tested against gen6 with piglit egl-create-context-verify-gl-flavor. Verified that this patch does not change the set of exposed EGL context flavors.

* intel: Set screen's api mask according to hw capabilities (v3)Chad Versace2013-01-152-11/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, intelInitScreen2 set DRIScreen::api_mask with the hacky heuristic below: if (gen >= 3) api_mask = GL | GLES1 | GLES2; else api_mask = 0; This hack was likely broken on gen2 (i830), but I don't care enough to properly investigate. 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. Verified that this patch does not change the set of exposed EGL context flavors. v2: - Replace the if-tree on gen with a switch, for Ian. - Unconditionally enable the DRI_API_OPENGL bit, for Ian. v3: - Drop max gl version to 1.4 on gen3 if !has_occlusion_query, because occlusion queries entered core in 1.5.

* 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.

| | | | | | | | | | | | | | | | | | The specification requires that query results are processed in order, (when one query result is returned, all previous query of the same type must also be available). The implementation was failing this requirement in the case of BeginQuery and EndQuery with no intervening drawing, (the result would be made available immediately without flushing previous queries).

This functionality is made conditional on a new MESA_META_OCCLUSION_QUERY bit so that meta-operations which should generate fragments can continue to get the current behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | These are optimizations which make MSAA a lot faster. The MSAA work is complete with this commit. (except for enablement of AA optimizations for RGBA16F, for which a patch is ready and waiting until the kernel CS checker fix lands) MSAA can't be made any faster as far as hw programming is concerned. The catch is only one process and one colorbuffer can use the optimizations at a time. There usually is only one MSAA colorbuffer, so it shouldn't be an issue. Also, there is a limit on the size of MSAA colorbuffer resolution in terms of megapixels. If the limit is surpassed, the AA optimizations are disabled. The limit is: - 1 Mpix on low-end and some mid-level chipsets (1024x768 and 1280x720) - 2 Mpix on some mid-level chipsets (1600x1200 and 1920x1080) - 3 or 4 Mpix on high-end chipsets (2048x1536 or 2560x1600, respectively) It corresponds to the number of raster pipes (= GB pipes) available, each pipe can hold 1 Mpix of AA compression data. If it's enabled, the driver prints to stdout: radeon: Acquired access to AA optimizations.

| | | | | | | | | | | | | | | | | | | | | | | | | | The hardware does not support a render target without an alpha channel. So when the user creates a render buffer with no alpha channel, there actually is storage available for alpha internally. It requires special care to avoid these unwanted alpha bits from causing any problems. Specifically, when blending, and when the blend factors would read the destination alpha values, this commit coerces the blend factors to instead be either 0 or 1 as appropriate.
