The fogcoord calue was not pushed to GPU because of implicit float to int conversion.
Fix is to use float pointer to buffer object so no conversion is done in assigment
|
|
|
|
If the pbuffer surface is current, gctx is set to the current context.
Make sure it is set to OpenGL ES 1 context again before binding.
|
|
Mention that EGL_DRIVER should be a full path, and add a link from
envvars.html to egl.html.
|
|
EGL_SURFACE_TYPE is a config attribute, not a surface attribute. Thanks
to Mike Stroyan for pointing out this error.

This fixes a bug reported by Christoph Bumiller on mesa3d-dev.
When a texture is first created as RGBA, then re-defined with
glTexImage(internalFormat=GL_DEPTH_COMPONENT) we failed to deallocate
the original texture. When this texture was bound as a FBO surface,
the depth/Z surface format was RGBA instead of Z. Depending on the
driver this led to a failed assertion or FBO validation failure.
This patch does three things:
1. Remove ancient code that mysteriously tested if we were replacing
the smallest mipmap level and tested if the texture was not a cube map
texture. I can't see any reason for those tests.
2. Move the width=height=depth=0 test to after the code which frees
texture data. Calling glTexImage with width=height=depth=0 and data=NULL
is a way to free a single mipmap level.
3. Update the code comments.
There are no apparent conform, glean or piglit regressions from this change.

Before, _mesa_find_free_register() would scan the given shader to
find a free/unused register of the given type. But subsequent calls
would return the same register again. This caused a failure in the
_mesa_remove_output_reads() function which sometimes needs several
free temps.
Now use a new function which build a vector of 'used' flags and another
function which searches that vector for an unused register starting at
a position that's incremented for each call.
Fixes fd.o bug 26317. Note that a regression test for this has been
added to the glean/glsl1 test.

Oh look, more gears. Seems to work just fine though.
|
|
This was being calculated the same way in two different places.
Now just do it in st_translate_fragment_program().
|
|
Was being calculated and not used. Also was probably incorrect...

Add missing attributes and use correct types in _EGLSurface. Remove
ifdef tests that serve no purpose. Update _eglQuerySurface and
_eglSurfaceAttrib for missing queries and checks.
|
|
Add support EGL_KHR_vg_parent_image and EGL_KHR_gl_*. This is as simple
as adding some flags that can be enabled. Individual drivers need to
implement the extensions before enbaling the flags.

EGL_SCREEN_BIT_MESA is a valid bit only when EGL_MESA_screen_surface is
supported.

This changes _eglInitConfig to take the display as its argument.
|
|
Change _eglInitSurface, _eglInitContext, and _eglInitImage to take an
_EGLDisplay instead of an _EGLDriver. This is a more natural form, and
plus, the display encodes information such as the extensions supported
that might be required for attribute list parsing.
|
|
Refactor attribute list parsing code to _eglParseImageAttribList.
|
|
Refactor attribute list parsing code to _eglParseContextAttribList. Add
a check to make sure the config supports the client API.

They are either unit tests or to demonstrate how functions are supposed
to be used. The unit test is outdated and it should be better to take a
look at any of the working drivers to see how a function is used.
|
|
Add config caveat, bind-to-texture, and renderable type. Remove double
buffer and stereo attributes.
|
|
Configs without a renderable type are still informative for programs
such as eglinfo.
|
|
There is now _eglGetAPIContext that can return the current context of
the given API.
