Re: [Mesa-dev] OpenGL ES 3.0 support

[violin yanev]

Thanks for your replies guys!

The output of eglinfo is:
EGL API version: 1.4
EGL vendor string: Mesa Project
EGL version string: 1.4 (DRI2)
EGL client APIs: OpenGL OpenGL_ES OpenGL_ES2
EGL extensions string:
EGL_MESA_drm_image EGL_WL_bind_wayland_display EGL_KHR_image_base
EGL_KHR_image_pixmap EGL_KHR_image EGL_KHR_gl_renderbuffer_image
EGL_KHR_surfaceless_context EGL_KHR_create_context
EGL_NOK_swap_region EGL_NOK_texture_from_pixmap
EGL_NV_post_sub_buffer

So apparently ES3.0 is not a supported API :(

@Jordan: do you know if one can reenable ES3 on Intel graphics? Is a
special flag expected? I had read a message that Fedora 18 will enable
ES3.0 by default?

 I believe this Fedora commit which disabled GL3 for Intel graphics
 will also disable GLES3 for Intel graphics:

[Mesa-dev] OpenGL ES 3.0 support

Hello,

I was eager to try the OpenGL ES 3.0 support on the newest Mesa 9.1.

I installed the latest Fedora Rawhide on my Sandy Bridge. I think the
graphics chip is HD 2000, lspci says I have a Xeon E3-1200 V2/3rd gen
processor. glxinfo states that I have Mesa 9.1, and lsmod lists i915 as my
VGA driver, so it seems that the setup is right. I wrote a simple EGL
program (used the opengles2 example as basis) and tried to create am OpenGL
ES3 context. I tried two methods:

1) Giving a value of 3 in the API version eglChooseConfig
(EGL_CONTEXT_CLIENT_VERSION=3)
This had the result that no matching configs were found.
2) Supplying the EGL_OPENGL_ES3_BIT_KHR flag in eglCreateContext (the
EGL_KHR_create_context
extension is present). This didn't work either (eglCreateContext returns an
error).
