egl/dri2: Fix min/max swap interval of configs
The commit below exposed a bug in dri2_add_config.
commit 3998f8c6b5da1a223926249755e54d8f701f81ab
Author: Ralf Jung <post@ralfj.de>
Date: Tue Apr 9 14:09:50 2013 +0200
egl/x11: Fix initialisation of swap_interval
This little code snippet near the bottom of dri2_add_config,
if (double_buffer) {
...
conf->base.MinSwapInterval = dri2_dpy->min_swap_interval;
conf->base.MaxSwapInterval = dri2_dpy->max_swap_interval;
}
it never did what it claimed to do. The assignment never changed the value
of conf->base.MaxSwapInterval, because dri2_dpy->max_swap_interval was,
until the above exposing commit, unitialized here. That is,
conf->base.MaxSwapInterval was 0 before and after assignment. Ditto for
the min swap interval.
Above the troublesome code snippet, the call to _eglFilterArray rejects
the config as unmatching if its swap interval bounds differ from the base
config's. Before the exposing commit, at the call to _eglFilterArray, the
swap interval bounds were always [0,0], and hence no config was rejected
due to swap interval.
After the exposing commit, _eglFilterArray incorrectly rejected some
configs, which prevented dri2_egl_config::dri_double_config from getting
set for the rejected config, which resulted in a NULL pointer getting
passed into dri2CreateNewDrawable, and then segfault.
The solution: set the swap interval bounds before _eglFilterArray.

egl/dri2: Add plumbing for EGL_OPENGL_ES3_BIT_KHR
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.

egl/dri2: Add plumbing for EGL_OPENGL_ES3_BIT_KHR
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.

egl/dri2: Add plumbing for EGL_OPENGL_ES3_BIT_KHR
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.
