st/mesa: do vertex and fragment color clamping in shaders
For ARB_color_buffer_float. Most hardware can't do it and st/mesa is
the perfect place for a fallback.
The exceptions are:

- nv50 (both)
- nvc0 (both)

gallium: remove PIPE_SHADER_CAP_OUTPUT_READ
r600g is the only driver which has made use of it. The reason the CAP was
added was to fix some piglit tests when the GLSL pass lower_output_reads
didn't exist.
However, not removing output reads breaks the fallback for glClampColorARB,
which assumes outputs are not readable. The fix would be non-trivial
and my personal preference is to remove the CAP, considering that reading
outputs is uncommon and that we can now use lower_output_reads to fix
the issue that the CAP was supposed to workaround in the first place.

This fixes a build problem where EGL links to libgbm.la, which encodes

libglapi.so, which is wrong and breaks when there isn't one.

EGL doesnt define howto manage different native platforms.
So mesa has a builtime configurable default platform,

This caused unneeded bugreports, when EGL_PLATFORM was forgotten.
Detection is grouped into basic types of NativeDisplays (which itself
needs to be detected). The final decision is based on characteristcs
of these basic types:
File Desciptor based platforms (fbdev):
- fstat(2) to check for being a fd that belongs to a character device
- check kernel subsystem (todo)
Pointer to structuctures (x11, wayland, drm/gbm):
- mincore(2) to check whether its valid pointer to some memory.
- magic elements (e.g. pointers to exported symbols):

o gbm stores pointer to its constructor (first elm.)
o x11 as a fallback (FIXME?)

When the user sets EGL_DRIVER to egl_dri2 (or egl_glx), make sure the
built-in driver is used. The user might leave the outdated egl_dri2.so
(or egl_glx.so) on the filesystem and we do not want to load it.
The idea is to be able to match a driver using the following order
try egl_gallium with hw renderer
try egl_dri2
try egl_gallium with sw renderer
try egl_glx
given the module list
egl_gallium
egl_dri2
egl_glx
For that, UseFallback initialization option is added. The module list
is matched twice: with the option unset and with the option set. In the
first pass, egl_gallium skips its sw renderer and egl_glx rejects to
initialize since UseFallback is not set. In the second pass,
egl_gallium skips its hw renderer and egl_dri2 rejects to initialize
since UseFallback is set. The process stops at the first driver that
initializes the display.
Reorder/rename and document the fields that should be set by the driver during
initialization. Drop the major/minor arguments from drv->API.Initialize.
Update SConscripts to re-enable or add support for EGL on windows and
x11 platforms respectively. targets/egl-gdi is replaced by
targets/egl-static, where "-static" means pipe drivers and state
trackers are linked to statically by egl_gallium, and egl_gallium is a
built-in driver of libEGL. There is no more egl_gallium.dll on Windows.
When the driver is the last reference to libEGL.so, unloading it will
cause libEGL.so to be unmapped and give problems. Disable the unloading
for now. Still have to figure out the right timing to unload drivers.
Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.
This call sequence
eglMakeCurrent(dpy, surf, surf, ctx1);
eglMakeCurrent(dpy, surf, surf, ctx2);
should be valid if ctx1 and ctx2 have the same client API and are not
current in another thread.
Internally a mode belongs to a screen. But functions like
eglGetModeAttribMESA treat a mode as a display resource: a mode can be
looked up without a screen. Considering how KMS works, it is better to
stick to the current implementation.
To properly support looking up a mode without a screen, this commit
assigns each mode (of all screens) a unique ID.
The opaque nature of EGLImage implies that extensions almost always
define their own attributes. Move attributes in _EGLImage to
_EGLImageAttribs and add a helper function to parse attribute lists.
Remove the hard-to-get-right _eglBindContextToSurfaces. As well as fix
an assertion failure from b90a3e7d8b when
such call sequence is hit
eglMakeCurrent(dpy, surf1, surf1, ctx1);
eglMakeCurrent(dpy, surf2, surf2, ctx2);
eglMakeCurrent(dpy, surf1, surf1, ctx1);
The API of the context was not checked against EGL_RENDERABLE_TYPE when there
was no attribute list. Move the check to _eglInitContext, and be verbose about
common mistakes (EGL_RENDERABLE_TYPE not set, EGL_CONTEXT_CLIENT_VERSION not
set, or eglBindAPI not called).
These extensions allow an application to make a context current by
passing EGL_NO_SURFACE for the write and read surface in the call to
eglMakeCurrent. The motivation is that applications that only want to
render to client API targets (such as OpenGL framebuffer objects)
should not need to create a throw-away EGL surface just to get a
current context.
The function is used by _eglGetConfigs and _eglGetScreens. The array
size should not be limited by the buffer size when the buffer is NULL.
This fixes fdo bug #29052.
Driver loading is now splitted into two stages. In the first stage, an
_EGLModule is created for each driver: user driver, default drivers, and
all files in the search directories that start with "egl_". Modules are
not loaded at this stage.
In the second stage, each module is loaded to initialize a display. The
process stops at the first module that can initialize the display.
If eglGetProcAddress is called before eglInitialize, the same code path
will be taken to find the first module that supports
EGL_DEFAULT_DISPLAY. Because we do not want to initialize the display,
drv->Probe is used instead in this case.
This change makes st/egl build a single egl_gallium.so and multiple
st_<API>.so and pipe_<HW>.so. When a display is initialized, the
corresponding pipe driver will be loaded. When a context is created,
the corresponding state tracker will be loaded.
Unlike DRI drivers, no ABI compatibility is maintained. egl_gallium,
pipe drivers and state trackers should always be distributed as a single
package. As such, there is only a single src/gallium/targets/egl/ that
builds everything for the package.
Merge multiple egl_<platform>_<pipe>.so into a single
egl_gallium_<pipe>.so. The environment variable EGL_PLATFORM is now
used to modify the return value of _eglGetNativePlatform.
The extension defines eglGetDRMDisplay that creates an EGLDisplay from a
DRM fd. Calling eglCreateWindowSurace or eglCreatePixmapSurface with
such displays will generate EGL_BAD_NATIVE_WINDOW or
EGL_BAD_NATIVE_PIXMAP.
This commit introduces type-safe platform displays internally. A
platform display consists of a generic pointer and an enum that
specifies the platform.
An EGLDisplay is created from a platform display. Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform(). Platform windows and pixmaps may also be
introduced if needed.
This extension allows a color buffer to be used for both rendering and
texturing. EGL allows the use of color buffers of pbuffer drawables
for texturing, this extension extends this to allow the use of color
buffers of pixmaps too.
This extension adds a new function which provides an alternative to
eglSwapBuffers. eglSwapBuffersRegionNOK accepts two new parameters in
addition to those in eglSwapBuffers. The new parameters consist of a
pointer to a list of 4-integer blocks defining rectangles (x, y,
width, height) and an integer specifying the number of rectangles in
the list.
When there is no user driver or any matching display drivers we fall
back to the default driver. This patch lets us have a list of default
drivers instead of just one. The drivers are loaded in turn and we
attempt to initialize the display. If it fails we unload the driver
and move on to the next one.
Compared to the display driver mechanism, this avoids loading a number
of drivers and then only using one. Also, we call Initialize to see
if the driver will work instead of relying on Probe. To know for sure
that a driver will work, Probe really have to do a full Initialize, so
we will just use Initialize directly.
eglplatform.h pulls in Xlib.h on X11 platforms. Likewise, the egl glx

There is no effective changes given how the function is called. It is
still not trivial, but it should be more readable and resemble
_eglBindContextToThread a lot.
When a newly bound context is the same as the previously bound one,
_eglBindContextToThread should still return the context instead of NULL.
This gives the driver a chance to flush the context.
It was added to skip checking EGLDisplay, EGLSurface, and etc. It is
never defined and the spec does not allow the checks to be skipped.
Remove it for good.
The macros give warnings when compiled with -pedantic. This commit is
based on a patch by Brian Paul, with minor changes to add do {} while(0)
and rename the check macros.
This gives a simple access control to the display. It is potentially
slow, but a finer grained mutex can always be used in the future. The
benefit of this simple approach is that drivers need not to worry about
thread-safety.
Use macros to record the status of the function call before returning.
This is the only way that eglGetError can return the status of the most
recent function call.
Add _EGL_CHECK_* which will replace _EGL_DECLARE_* for error checking.
Move _eglCheck* earlier in the file so that the macros and the functions
are grouped together.
Both a link and a binding creates a reference to the resource. Drivers
should not destroy the resource when there is a reference. The
difference is better described in doc/egl.html.
There are standard typecast functions that are common to most drivers.
They are used to typecast, for example, an _EGLSurface to a
driver-defined type.
This commits define _EGL_DRIVER_STANDARD_TYPECASTS and
_EGL_DRIVER_TYPECAST that should hopefully save some typings for driver
writers.
Rename _eglPreloadFile to _eglLoaderFile, and _eglPreloadFile to
_eglLoaderFile. There are several _eglPreload* functions. The
callbacks do not belong to them and it should be better to give them a
different prefix.
EGL_DRIVERS_PATH gives a list of colon-separated directories. The given
directories will be searched when preloading drivers.
This is based on Mike Stroyan's patch, which honors the variable in
_eglPreloadDisplayDrivers. It is extended to honor the variable also in
_eglPreloadUserDriver and _eglPreloadDefaultDriver in this version.
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.
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.
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.
When no context or surface are given, the display is allowed to be
uninitialized. Most drivers cannot handle an uninitialized display.
But they are updated to at least throw a fatal message.
It works similar to _eglMakeCurrent, except that the old context and
surfaces are returned instead of destroyed. _eglMakeCurrent is now
calling the new _eglBindContext.
The driver pointer of the display was used to decide whether a display
is initialized. Use a boolean for that purpose allows accessing the
driver of an uninitialized display.
An unlinked resource may still be a current resource such as current
surfaces. There might still be a need to know which display the
unlinked resource belongs to.
Add a platform specific function to turn a library name to a library
path. It is used to convert EGL_DRIVER or the default driver to a
library path that can be loaded.
With the addition egl_x11_swrast, egl_softpipe is sort of deprecated.
The new driver serves the same purpose as egl_softpipe does. It is
based on egl_g3d and provides more features.
In current design, multiple drivers will probe the same display and the
best driver is determined. The cache can be used by the drivers to
store and share the probed data.
It can be used to load the user driver specified by EGL_DRIVER, or a set
of drivers specified by EGL_DISPLAY, or the default driver, and in that
order.
