+Dependencies
+
+ Reguires EGL 1.4 or later. This extension is written against the
+ wording of the EGL 1.4 specification.
+
+ EGL_KHR_base_image is required.
+
+Overview
+
+ This extension provides entry points for integrating EGLImage with the
+ Linux DRM mode setting and memory management drivers. The extension
+ lets applications create EGLImages without a client API resource and
+ lets the application get the DRM buffer handles.
+
+IP Status
+
+ Open-source; freely implementable.
+
+New Procedures and Functions
+
+ EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
+ const EGLint *attrib_list);
+
+ EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
+ EGLImageKHR image,
+ EGLint *name,
+ EGLint *handle,
+ EGLint *stride);
+
+New Tokens
+
+ Accepted in the <attrib_list> parameter of eglCreateDRMImageMESA:
+
+ EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
+ EGL_DRM_BUFFER_USE_MESA 0x31D1
+
+ Accepted as values for the EGL_IMAGE_FORMAT_MESA attribute:
+
+ EGL_DRM_BUFFER_FORMAT_ARGB32_MESA 0x31D2
+
+ Bits accepted in EGL_DRM_BUFFER_USE_MESA:
+
+ EGL_DRM_BUFFER_USE_SCANOUT_MESA 0x0001
+ EGL_DRM_BUFFER_USE_SHARE_MESA 0x0002
+
+ Accepted in the <target> parameter of eglCreateImageKHR:
+
+ EGL_DRM_BUFFER_MESA 0x31D3
+
+ Use when importing drm buffer:
+
+ EGL_DRM_BUFFER_STRIDE_MESA 0x31D4
+ EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
+
+Additions to the EGL 1.4 Specification:
+
+ To create a DRM EGLImage, call
+
+ EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
+ const EGLint *attrib_list);
+
+ In the attribute list, pass EGL_WIDTH, EGL_HEIGHT and format and
+ use in the attrib list using EGL_DRM_BUFFER_FORMAT_MESA and
+ EGL_DRM_BUFFER_USE_MESA. The only format specified by this
+ extension is EGL_DRM_BUFFER_FORMAT_ARGB32_MESA, where each pixel
+ is a CPU-endian, 32-bit quantity, with alpha in the upper 8 bits,
+ then red, then green, then blue. The bit values accepted by
+ EGL_DRM_BUFFER_USE_MESA are EGL_DRM_BUFFER_USE_SCANOUT_MESA and
+ EGL_DRM_BUFFER_USE_SHARE_MESA. EGL_DRM_BUFFER_USE_SCANOUT_MESA
+ requests that the created EGLImage should be usable as a scanout
+ buffer with the DRM kernel modesetting API. The
+ EGL_DRM_BUFFER_USE_SHARE_MESA bit requests that the EGLImage can
+ be shared with other processes by passing the underlying DRM
+ buffer name.
+
+ To create a process local handle or a global DRM name for a
+ buffer, call
+
+ EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
+ EGLImageKHR image,
+ EGLint *name,
+ EGLint *handle,
+ EGLint *stride);
+
+ If <name> is non-NULL, a global name is assigned to the image and
+ written to <name>, the handle (local to the DRM file descriptor,
+ for use with DRM kernel modesetting API) is written to <handle> if
+ non-NULL and the stride (in bytes) is written to <stride>, if
+ non-NULL.
+
+ Import a shared buffer by calling eglCreateImageKHR with
+ EGL_DRM_BUFFER_MESA as the target, using EGL_WIDTH, EGL_HEIGHT,
+ EGL_DRM_BUFFER_FORMAT_MESA, EGL_DRM_BUFFER_STRIDE_MESA
+ in the attrib list.
+
+Issues
+
+ 1. Why don't we use eglCreateImageKHR with a target that
+ indicates that we want to create an EGLImage from scratch?
+
+ RESOLVED: The eglCreateImageKHR entry point is reserved for
+ creating an EGLImage from an already existing client API
+ resource. This is fine when we're creating the EGLImage from
+ an existing DRM buffer name, it doesn't seem right to overload
+ the function to also allocate the underlying resource.
+
+ 2. Why don't we use an eglQueryImageMESA type functions for
+ querying the DRM EGLImage attributes (name, handle, and stride)?
+
+ RESOLVED: The eglQueryImage function has been proposed often,
+ but it goes against the EGLImage design. EGLImages are opaque
+ handles to a 2D array of pixels, which can be passed between
+ client APIs. By referenceing an EGLImage in a client API, the
+ EGLImage target (a texture, a renderbuffer or such) can be
+ used to query the attributes of the EGLImage. We don't have a
+ full client API for creating and querying DRM buffers, though,
+ so we use a new EGL extension entry point instead.

+
+<H1>Development Notes</H1>
+
+
+<H2>Adding Extentions</H2>
+
+<p>
+To add a new GL extension to Mesa you have to do at least the following.
+
+<ul>
+<li>
+ If glext.h doesn't define the extension, edit include/GL/gl.h and add
+ code like this:
+ <pre>
+ #ifndef GL_EXT_the_extension_name
+ #define GL_EXT_the_extension_name 1
+ /* declare the new enum tokens */
+ /* prototype the new functions */
+ /* TYPEDEFS for the new functions */
+ #endif
+ </pre>
+</li>
+<li>
+ In the src/mesa/glapi/ directory, add the new extension functions and
+ enums to the gl_API.xml file.
+ Then, a bunch of source files must be regenerated by executing the
+ corresponding Python scripts.
+</li>
+<li>
+ Add a new entry to the <code>gl_extensions</code> struct in mtypes.h
+</li>
+<li>
+ Update the <code>extensions.c</code> file.
+</li>
+<li>
+ From this point, the best way to proceed is to find another extension,
+ similar to the new one, that's already implemented in Mesa and use it
+ as an example.
+</li>
+<li>
+ If the new extension adds new GL state, the functions in get.c, enable.c
+ and attrib.c will most likely require new code.
+</li>
+</ul>
+
+
+
+<H2>Coding Style</H2>
+
+<p>
+Mesa's code style has changed over the years. Here's the latest.
+</p>
+
+<p>
+Comment your code! It's extremely important that open-source code be
+well documented. Also, strive to write clean, easily understandable code.
+</p>
+
+<p>
+3-space indentation
+</p>
+
+<p>
+If you use tabs, set them to 8 columns
+</p>
+
+<p>
+Brace example:
+</p>
+<pre>
+ if (condition) {
+ foo;
+ }
+ else {
+ bar;
+ }
+</pre>
+
+<p>
+Here's the GNU indent command which will best approximate my preferred style:
+</p>
+<pre>
+ indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
+</pre>
+
+
+<p>
+Local variable name example: localVarName (no underscores)
+</p>
+
+<p>
+Constants and macros are ALL_UPPERCASE, with _ between words
+</p>
+
+<p>
+Global variables are not allowed.
+</p>
+
+<p>
+Function name examples:
+</p>
+<pre>
+ glFooBar() - a public GL entry point (in glapi_dispatch.c)
+ _mesa_FooBar() - the internal immediate mode function
+ save_FooBar() - retained mode (display list) function in dlist.c
+ foo_bar() - a static (private) function
+ _mesa_foo_bar() - an internal non-static Mesa function
+</pre>
+
+
+<H2>Making a New Mesa Release</H2>
+
+<p>
+These are the instructions for making a new Mesa release.
+</p>
+
+<H3>Get latest source files</H3>
+<p>
+Use git to get the latest Mesa files from the git repository, from whatever
+branch is relevant.
+</p>
+
+
+<H3>Verify and update version info</H3>
+<p>
+Create/edit the docs/relnotes-x.y.html file to document what's new in the release.
+Add the new relnotes-x.y.html file to <a href="relnotes.html">relnotes.html</a>.
+</p>
+
+<p>
+Update the MESA_MAJOR, MESA_MINOR and MESA_TINY version numbers in
+configs/default.
+Also update the VERSION line in the top-level Makefile.
+</p>
+
+<p>
+Make sure the values in src/mesa/main/version.h are correct.
+</p>
+
+<p>
+Update docs/news.html.
+</p>
+
+<p>
+Check in all updates to git.
+</p>
+
+<p>
+Tag the files with the release name (in the form <b>mesa_X_Y</b>)
+with: <code>git tag -a mesa_X_Y</code>
+Then: <code>git push origin mesa_X_Y</code>
+</p>
+
+
+<H3>Make the tarballs</H3>
+<p>
+Make a symbolic link from $(DIRECTORY) to 'Mesa'. For example,
+<code>ln -s Mesa Mesa-7.5</code>
+This is needed in order to make a correct tar file in the next step.
+</p>
+
+<p>
+Make the distribution files. From inside the Mesa directory:
+<pre>
+ make tarballs
+</pre>
+
+<p>
+After the tarballs are created, the md5 checksums for the files will
+be computed.
+Add them to the docs/relnotes-X.Y.html file.
+</p>
+
+<p>
+Copy the distribution files to a temporary directory, unpack them,
+compile everything, and run some demos to be sure everything works.
+</p>
+
+<H3>Update the website and announce the release</H3>
+<p>
+Follow the directions on SourceForge for creating a new "release" and
+uploading the tarballs.
+</p>
+
+<p>
+Basically, to upload the tarball files with:
+<br>
+<code>
+rsync -avP ssh Mesa*-X.Y.* USERNAME@frs.sourceforge.net:uploads/
+</code>
+</p>
+
+<p>
+Update the web site by copying the docs/ directory's files to
+/home/users/b/br/brianp/mesa-www/htdocs/ with:
+<br>
+<code>
+sftp USERNAME,mesa3d@web.sourceforge.net
+</code>
+</p>
+
+<p>
+Make an announcement on the mailing lists:

More information -about EGL can be found at -<a href="http://www.khronos.org/egl/" target="_parent"> -http://www.khronos.org/egl/</a>.</p> - -<p>The Mesa's implementation of EGL uses a driver architecture. The main -library (<code>libEGL</code>) is window system neutral. It provides the EGL -API entry points and helper functions for use by the drivers. Drivers are -dynamically loaded by the main library and most of the EGL API calls are -directly dispatched to the drivers.</p> - -<p>The driver in use decides the window system to support. For drivers that -support hardware rendering, there are usually multiple drivers supporting the -same window system. Each one of of them supports a certain range of graphics -cards.</p> - -<h2>Build EGL</h2> - -<ol> -<li> -<p>Run <code>configure</code> with the desired state trackers and enable -the Gallium driver for your hardware. For example</p> - -<pre> - $ ./configure --enable-gles-overlay --with-state-trackers=egl,vega --enable-gallium-intel -</pre> - -<p>The main library and OpenGL is enabled by default. The first option enables -<a href="opengles.html">OpenGL ES 1.x and 2.x</a>. The <code>egl</code> state -tracker is needed by a number of EGL drivers. EGL drivers will be covered -later. The <a href="openvg.html">vega state tracker</a> provides OpenVG -1.x.</p> -</li> - -<li>Build and install Mesa as usual.</li> -</ol> - -<p>In the given example, it will build and install <code>libEGL</code>, -<code>libGL</code>, <code>libGLESv1_CM</code>, <code>libGLESv2</code>, -<code>libOpenVG</code>, and one or more EGL drivers.</p> - -<h3>Configure Options</h3> - -<p>There are several options that control the build of EGL at configuration -time</p> - -<ul> -<li><code>--enable-egl</code> - -<p>By default, EGL is enabled. When disabled, the main library and the drivers -will not be built.</p> - -</li> - -<li><code>--with-egl-driver-dir</code> - -<p>The directory EGL drivers should be installed to. If not specified, EGL -drivers will be installed to <code>${libdir}/egl</code>.</p> - -</li> - -<li><code>--with-egl-platforms</code> - -<p>List the platforms (window systems) to support. Its argument is a comma -seprated string such as <code>--with-egl-platforms=x11,drm</code>. It decides -the platforms a driver may support. The first listed platform is also used by -the main library to decide the native platform: the platform the EGL native -types such as <code>EGLNativeDisplayType</code> or -<code>EGLNativeWindowType</code> defined for.</p> - -<p>The available platforms are <code>x11</code>, <code>drm</code>, -<code>fbdev</code>, and <code>gdi</code>. The <code>gdi</code> platform can -only be built with SCons.</p> - -</li> - -<li><code>--with-state-trackers</code> - -<p>The argument is a comma separated string. It is usually used to specify the -rendering APIs, such as OpenVG, to build. But it is also used to specify -<code>egl</code> state tracker that <code>egl_gallium</code> depends on.</p> - -</li> - -<li><code>--enable-gles-overlay</code> - -<p>OpenGL and OpenGL ES are not controlled by -<code>--with-state-trackers</code>. OpenGL is always built. To build OpenGL -ES, this option must be explicitly given.</p> - -</li> - -<li><code>--enable-gles1</code> and <code>--enable-gles2</code> - -<p>Unlike <code>--enable-gles-overlay</code>, which builds one library for each -rendering API, these options enable OpenGL ES support in OpenGL. The result is -one big library that supports multiple APIs.</p> - -</li> - -</ul> - -<h2>Use EGL</h2> - -<h3>Demos</h3> - -<p>There are demos for the client APIs supported by EGL. They can be found in -mesa/demos repository.</p> - -<h3>Environment Variables</h3> - -<p>There are several environment variables that control the behavior of EGL at -runtime</p> - -<ul> -<li><code>EGL_DRIVERS_PATH</code> - -<p>By default, the main library will look for drivers in the directory where -the drivers are installed to. This variable specifies a list of -colon-separated directories where the main library will look for drivers, in -addition to the default directory. This variable is ignored for setuid/setgid -binaries.</p> - -</li> - -<li><code>EGL_DRIVER</code> - -<p>This variable specifies a full path to an EGL driver and it forces the -specified EGL driver to be loaded. It comes in handy when one wants to test a -specific driver. This variable is ignored for setuid/setgid binaries.</p> - -<p><code>egl_gallium</code> dynamically loads hardware drivers and client API -modules found in <code>EGL_DRIVERS_PATH</code>. Thus, specifying this variable -alone is not sufficient for <code>egl_gallium</code> for uninstalled build.</p> - -</li> - -<li><code>EGL_PLATFORM</code> - -<p>This variable specifies the native platform. The valid values are the same -as those for <code>--with-egl-platforms</code>. When the variable is not set, -the main library uses the first platform listed in -<code>--with-egl-platforms</code> as the native platform</p> - -</li> - -<li><code>EGL_LOG_LEVEL</code> - -<p>This changes the log level of the main library and the drivers. The valid -values are: <code>debug</code>, <code>info</code>, <code>warning</code>, and -<code>fatal</code>.</p> - -</li> - -<li><code>EGL_SOFTWARE</code> - -<p>For drivers that support both hardware and software rendering, setting this -variable to true forces the use of software rendering.</p> - -</li> -</ul> - -<h2>EGL Drivers</h2> - -<ul> -<li><code>egl_gallium</code> - -<p>This driver is based on Gallium3D. It supports all rendering APIs and -hardwares supported by Gallium3D. It is the only driver that supports OpenVG. -The supported platforms are X11, KMS, FBDEV, and GDI.</p> - -</li> - -<li><code>egl_glx</code> - -<p>This driver provides a wrapper to GLX. It uses exclusively GLX to implement -the EGL API. It supports both direct and indirect rendering when the GLX does. -It is accelerated when the GLX is. As such, it cannot provide functions that -is not available in GLX or GLX extensions.</p> -</li> - -<li><code>egl_dri2</code> - -<p>This driver supports the X Window System as its window system. It functions -as a DRI2 driver loader. Unlike <code>egl_glx</code>, it has no dependency on -<code>libGL</code>. It talks to the X server directly using DRI2 protocol.</p> - -</li> -<li><code>egl_dri</code> - -<p>This driver lacks maintenance and does <em>not</em> build. It is similiar -to <code>egl_dri2</code> in that it functions as a DRI(1) driver loader. But -unlike <code>egl_dri2</code>, it supports Linux framebuffer devices as its -window system and supports EGL_MESA_screen_surface extension. As DRI1 drivers -are phasing out, it might eventually be replaced by <code>egl_dri2</code>.</p> - -</li> -</ul> - -<h2>Developers</h2> - -<p>The sources of the main library and the classic drivers can be found at -<code>src/egl/</code>.

+
+<h1>Mesa EGL</h1>
+
+<p>The current version of EGL in Mesa implements EGL 1.4. More information
+about EGL can be found at
+<a href="http://www.khronos.org/egl/" target="_parent">
+http://www.khronos.org/egl/</a>.</p>
+
+<p>The Mesa's implementation of EGL uses a driver architecture. The main
+library (<code>libEGL</code>) is window system neutral. It provides the EGL
+API entry points and helper functions for use by the drivers. Drivers are
+dynamically loaded by the main library and most of the EGL API calls are
+directly dispatched to the drivers.</p>
+
+<p>The driver in use decides the window system to support.</p>
+
+<h2>Build EGL</h2>
+
+<ol>
+<li>
+<p>Run <code>configure</code> with the desired client APIs and enable
+the driver for your hardware. For example</p>
+
+<pre>
+ $ ./configure --enable-gles2 --enable-openvg --enable-gallium-nouveau
+</pre>
+
+<p>The main library and OpenGL is enabled by default. The first option above
+enables <a href="opengles.html">OpenGL ES 2.x</a>. The second option enables
+<a href="openvg.html">OpenVG</a>.</p>
+
+</li>
+
+<li>Build and install Mesa as usual.</li>
+</ol>
+
+<p>In the given example, it will build and install <code>libEGL</code>,
+<code>libGL</code>, <code>libGLESv1_CM</code>, <code>libGLESv2</code>,
+<code>libOpenVG</code>, and one or more EGL drivers.</p>
+
+<h3>Configure Options</h3>
+
+<p>There are several options that control the build of EGL at configuration
+time</p>
+
+<ul>
+<li><code>--enable-egl</code>
+
+<p>By default, EGL is enabled. When disabled, the main library and the drivers
+will not be built.</p>
+
+</li>
+
+<li><code>--with-egl-driver-dir</code>
+
+<p>The directory EGL drivers should be installed to. If not specified, EGL
+drivers will be installed to <code>${libdir}/egl</code>.</p>
+
+</li>
+
+<li><code>--with-egl-platforms</code>
+
+<p>List the platforms (window systems) to support. Its argument is a comma
+seprated string such as <code>--with-egl-platforms=x11,drm</code>. It decides
+the platforms a driver may support. The first listed platform is also used by
+the main library to decide the native platform: the platform the EGL native
+types such as <code>EGLNativeDisplayType</code> or
+<code>EGLNativeWindowType</code> defined for.</p>
+
+<p>The available platforms are <code>x11</code>, <code>drm</code>,
+<code>fbdev</code>, and <code>gdi</code>. The <code>gdi</code> platform can
+only be built with SCons. Unless for special needs, the build system should
+select the right platforms automatically.</p>
+
+</li>
+
+<li><code>--enable-gles1</code> and <code>--enable-gles2</code>
+
+<p>These options enable OpenGL ES support in OpenGL. The result is one big
+internal library that supports multiple APIs.</p>
+
+</li>
+
+<li><code>--enable-gles-overlay</code>
+
+<p>This option enables OpenGL ES as separate internal libraries. This is an
+alternative approach to enable OpenGL ES.</p>
+
+<p>This is only supported by <code>egl_gallium</code>. For systems using DRI
+drivers, <code>--enable-gles1</code> and <code>--enable-gles2</code> are
+suggested instead as all drivers will benefit.</p>
+
+</li>
+
+<li><code>--enable-openvg</code>
+
+<p>OpenVG must be explicitly enabled by this option.</p>
+
+</li>
+
+<li><code>--enable-gallium-egl</code>
+
+<p>Explicitly enable or disable <code>egl_gallium</code>.</p>
+
+</li>
+
+</ul>
+
+<h2>Use EGL</h2>
+
+<h3>Demos</h3>
+
+<p>There are demos for the client APIs supported by EGL. They can be found in
+mesa/demos repository.</p>
+
+<h3>Environment Variables</h3>
+
+<p>There are several environment variables that control the behavior of EGL at
+runtime</p>
+
+<ul>
+<li><code>EGL_DRIVERS_PATH</code>
+
+<p>By default, the main library will look for drivers in the directory where
+the drivers are installed to. This variable specifies a list of
+colon-separated directories where the main library will look for drivers, in
+addition to the default directory. This variable is ignored for setuid/setgid
+binaries.</p>
+
+</li>
+
+<li><code>EGL_DRIVER</code>
+
+<p>This variable specifies a full path to an EGL driver and it forces the
+specified EGL driver to be loaded. It comes in handy when one wants to test a
+specific driver. This variable is ignored for setuid/setgid binaries.</p>
+
+</li>
+
+<li><code>EGL_PLATFORM</code>
+
+<p>This variable specifies the native platform. The valid values are the same
+as those for <code>--with-egl-platforms</code>. When the variable is not set,
+the main library uses the first platform listed in
+<code>--with-egl-platforms</code> as the native platform.</p>
+
+<p>Extensions like <code>EGL_MESA_drm_display</code> define new functions to
+create displays for non-native platforms. These extensions are usually used by
+applications that support non-native platforms. Setting this variable is
+probably required only for some of the demos found in mesa/demo repository.</p>
+
+</li>
+
+<li><code>EGL_LOG_LEVEL</code>
+
+<p>This changes the log level of the main library and the drivers. The valid
+values are: <code>debug</code>, <code>info</code>, <code>warning</code>, and
+<code>fatal</code>.</p>
+
+</li>
+
+<li><code>EGL_SOFTWARE</code>
+
+<p>For drivers that support both hardware and software rendering, setting this
+variable to true forces the use of software rendering.</p>
+
+</li>
+</ul>
+
+<h2>EGL Drivers</h2>
+
+<ul>
+<li><code>egl_dri2</code>
+
+<p>This driver supports both <code>x11</code> and <code>drm</code> platforms.
+It functions as a DRI driver loader. For <code>x11</code> support, it talks to
+the X server directly using (XCB-)DRI2 protocol.</p>
+
+<p>This driver can share DRI drivers with <code>libGL</code>.</p>
+
+</li>
+
+<li><code>egl_gallium</code>
+
+<p>This driver is based on Gallium3D. It supports all rendering APIs and
+hardwares supported by Gallium3D. It is the only driver that supports OpenVG.
+The supported platforms are X11, DRM, FBDEV, and GDI.</p>
+
+<p>This driver comes with its own hardware drivers
+(<code>pipe_<hw></code>) and client API modules
+(<code>st_<api></code>).</p>
+
+</li>
+
+<li><code>egl_glx</code>
+
+<p>This driver provides a wrapper to GLX. It uses exclusively GLX to implement
+the EGL API. It supports both direct and indirect rendering when the GLX does.
+It is accelerated when the GLX is. As such, it cannot provide functions that
+is not available in GLX or GLX extensions.</p>
+</li>
+</ul>
+
+<h2>Packaging</h2>
+
+<p>The ABI between the main library and its drivers are not stable. Nor is
+there a plan to stabilize it at the moment. Of the EGL drivers,
+<code>egl_gallium</code> has its own hardware drivers and client API modules.
+They are considered internal to <code>egl_gallium</code> and there is also no
+stable ABI between them. These should be kept in mind when packaging for
+distribution.</p>
+
+<p>Generally, <code>egl_dri2</code> is preferred over <code>egl_gallium</code>
+when the system already has DRI drivers. As <code>egl_gallium</code> is loaded
+before <code>egl_dri2</code> when both are available, <code>egl_gallium</code>
+may either be disabled with <code>--disable-gallium-egl</code> or packaged
+separately.</p>
+
+<h2>Developers</h2>
+
+<p>The sources of the main library and the classic drivers can be found at
+<code>src/egl/</code>. The sources of the <code>egl</code> state tracker can
+be found at <code>src/gallium/state_trackers/egl/</code>.</p>
+
+<p>The suggested way to learn to write a EGL driver is to see how other drivers
+are written. <code>egl_glx</code> should be a good reference. It works in any
+environment that has GLX support, and it is simpler than most drivers.</p>
+
+<h3>Lifetime of Display Resources</h3>
+
+<p>Contexts and surfaces are examples of display resources. They might live
+longer than the display that creates them.</p>
+
+<p>In EGL, when a display is terminated through <code>eglTerminate</code>, all
+display resources should be destroyed. Similarly, when a thread is released
+throught <code>eglReleaseThread</code>, all current display resources should be
+released. Another way to destory or release resources is through functions
+such as <code>eglDestroySurface</code> or <code>eglMakeCurrent</code>.</p>
+
+<p>When a resource that is current to some thread is destroyed, the resource
+should not be destroyed immediately. EGL requires the resource to live until
+it is no longer current. A driver usually calls
+<code>eglIs<Resource>Bound</code> to check if a resource is bound
+(current) to any thread in the destroy callbacks. If it is still bound, the
+resource is not destroyed.</p>
+
+<p>The main library will mark destroyed current resources as unlinked. In a
+driver's <code>MakeCurrent</code> callback,
+<code>eglIs<Resource>Linked</code> can then be called to check if a newly
+released resource is linked to a display. If it is not, the last reference to
+the resource is removed and the driver should destroy the resource. But it
+should be careful here because <code>MakeCurrent</code> might be called with an
+uninitialized display.</p>
+
+<p>This is the only mechanism provided by the main library to help manage the
+resources. The drivers are responsible to the correct behavior as defined by
+EGL.</p>
+
+<h3><code>EGL_RENDER_BUFFER</code></h3>
+
+<p>In EGL, the color buffer a context should try to render to is decided by the
+binding surface. It should try to render to the front buffer if the binding
+surface has <code>EGL_RENDER_BUFFER</code> set to
+<code>EGL_SINGLE_BUFFER</code>; If the same context is later bound to a
+surface with <code>EGL_RENDER_BUFFER</code> set to
+<code>EGL_BACK_BUFFER</code>, the context should try to render to the back
+buffer. However, the context is allowed to make the final decision as to which
+color buffer it wants to or is able to render to.</p>
+
+<p>For pbuffer surfaces, the render buffer is always
+<code>EGL_BACK_BUFFER</code>. And for pixmap surfaces, the render buffer is
+always <code>EGL_SINGLE_BUFFER</code>. Unlike window surfaces, EGL spec
+requires their <code>EGL_RENDER_BUFFER</code> values to be honored. As a
+result, a driver should never set <code>EGL_PIXMAP_BIT</code> or
+<code>EGL_PBUFFER_BIT</code> bits of a config if the contexts created with the
+config won't be able to honor the <code>EGL_RENDER_BUFFER</code> of pixmap or
+pbuffer surfaces.</p>
+
+<p>It should also be noted that pixmap and pbuffer surfaces are assumed to be
+single-buffered, in that <code>eglSwapBuffers</code> has no effect on them. It
+is desirable that a driver allocates a private color buffer for each pbuffer
+surface created. If the window system the driver supports has native pbuffers,
+or if the native pixmaps have more than one color buffers, the driver should
+carefully attach the native color buffers to the EGL surfaces, re-route them if
+required.</p>
+
+<p>There is no defined behavior as to, for example, how
+<code>glDrawBuffer</code> interacts with <code>EGL_RENDER_BUFFER</code>. Right
+now, it is desired that the draw buffer in a client API be fixed for pixmap and
+pbuffer surfaces. Therefore, the driver is responsible to guarantee that the
+client API renders to the specified render buffer for pixmap and pbuffer
+surfaces.</p>
+
+<h3><code>EGLDisplay</code> Mutex</h3>
+
+The <code>EGLDisplay</code> will be locked before calling any of the dispatch
+functions (well, except for GetProcAddress which does not take an
+<code>EGLDisplay</code>). This guarantees that the same dispatch function will
+not be called with the sample display at the same time. If a driver has access
+to an <code>EGLDisplay</code> without going through the EGL APIs, the driver
+should as well lock the display before using it.
+
+<h3>TODOs</h3>
+
+<ul>
+<li>Pass the conformance tests</li>
+<li>Mixed use of OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is supported. But
+which one of <code>libGL.so</code>, <code>libGLESv1_CM.so</code>, and
+<code>libGLESv2.so</code> should an application link to? Bad things may happen
+when, say, an application is linked to <code>libGLESv2.so</code> and
+<code>libcairo</code>, which is linked to <code>libGL.so</code> instead.</li>

+Introduction
+------------
+
+This document describes the implementation of the XFree86 4.0 libGL.so
+library defined by the Linux/OpenGL Base specification found at
+http://reality.sgi.com/opengl/linux/linuxbase.html.
+
+The documentation is divided into two sections:
+ User's Guide
+ Driver Developer's Guide
+
+Author: Brian Paul (brian@precisioninsight.com)
+Date: February 2000
+
+
+
+User's Guide
+------------
+
+Using libGL.so
+
+The libGL.so library defines the gl- and glX-prefixed functions needed to
+run OpenGL programs. OpenGL client applications should link with the
+-lGL option to use it.
+
+libGL.so serves two primary functions: GLX protocol generation for indirect
+rendering and loading/management of hardware drivers for direct rendering.
+
+When libGL.so initializes itself it uses the DRI to determine the
+appropriate hardware driver for each screen on the local X display.
+The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/
+directory. Drivers are named with the convention <name>_dri.so where
+<name> is a driver such as "tdfx", "i810", "gamma", etc.
+
+The LIBGL_DRIVERS_DIR environment variable may be used to specify a
+different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/.
+This environment variable is ignored in setuid programs for security
+reasons.
+
+When libGL.so is unable to locate appropriate hardware drivers it will
+fall back to using indirect GLX rendering.
+
+To aid in solving problems, libGL.so will print diagnostic messages to
+stderr if the LIBGL_DEBUG environment variable is defined.
+
+libGL.so is thread safe. The overhead of thread safety for common,
+single-thread clients is negligible. However, the overhead of thread
+safety for multi-threaded clients is significant. Each GL API call
+requires two calls to pthread_get_specific() which can noticably
+impact performance. Warning: libGL.so is thread safe but individual
+DRI drivers may not be. Please consult the documentation for a driver
+to learn if it is thread safe.
+
+
+
+Indirect Rendering
+
+You can force indirect rendering mode by setting the LIBGL_ALWAYS_INDIRECT
+environment variable. Hardware acceleration will not be used.
+
+
+
+libGL.so Extensibility
+
+libGL.so is designed to be extended without upgrading. That is,
+drivers may install new OpenGL extension functions into libGL.so
+without requiring libGL.so to be replaced. Clients of libGL.so should
+use the glXGetProcAddressEXT() function to obtain the address of
+functions by name. For more details of GLX_ARB_get_proc_address see
+http://oss.sgi.com/projects/ogl-sample/registry/ARB/get_proc_address.spec
+
+libGL.so is also designed with flexibility such that it may be used
+with many generations of hardware drivers to come.
+
+
+
+
+Driver Developer's Guide
+------------------------
+
+This section describes the requirements to make an XFree86 4.0
+libGL.so-compatible hardware driver. It is not intended for end
+users of libGL.so.
+
+
+XFree86 source files
+
+libGL.so is built inside XFree86 with sources found in xc/lib/GL/.
+Specifically, libGL.so is built from:
+
+ xc/lib/GL/glx/*.c
+ xc/lib/dri/XF86dri.c
+ xc/lib/dri/dri_glx.c
+ xc/lib/GL/mesa/src/glapi.c
+ xc/lib/GL/mesa/src/glapitemp.h
+ xc/lib/GL/mesa/src/glapitable.h
+ xc/lib/GL/mesa/src/glapioffsets.h
+ xc/lib/GL/mesa/src/glapinoop.c
+ xc/lib/GL/mesa/src/glheader.h
+ xc/lib/GL/mesa/src/glthread.c
+ xc/lib/GL/mesa/src/glthread.h
+ xc/lib/GL/mesa/src/X86/glapi_x86.S
+ xc/lib/GL/mesa/src/X86/assyntax.h
+
+Understand that the mesa/src/gl*.[ch] files are not tied to Mesa. They
+have no dependencies on the rest of Mesa and are designed to be reusable
+in a number of projects.
+
+The glapi_x86.X and assyntax.h files implement x86-optimized dispatch
+of GL functions. They are not required; C-based dispatch can be used
+instead, with a slight performance penalty.
+
+
+
+Driver loading and binding
+
+When libGL.so initializes itself (via the __glXInitialize function) a
+call is made to driCreateDisplay(). This function uses DRI facilities
+to determine the driver file appropriate for each screen on the local
+display. Each screen's driver is then opened with dlopen() and asked
+for its __driCreateScreen() function. The pointers to the __driCreateScreen()
+functions are kept in an array, indexed by screen number, in the
+__DRIdisplayRec struct.
+
+When a driver's __driCreateScreen() function is called, it must initialize
+a __DRIscreenRec struct. This struct acts as the root of a tree of
+function pointers which are called to create and destroy contexts and
+drawables and perform all the operations needed by the GLX interface.
+See the xc/lib/GL/glx/glxclient.h file for details.
+
+
+
+Dynamic Extension Function Registration
+
+In order to provide forward compatibility with future drivers, libGL.so
+allows drivers to register new OpenGL extension functions which weren't
+known when libGL.so was built.
+
+The register_extensions() function in xc/lib/GL/dri/dri_glx.c is called
+as soon as libGL.so is loaded. This is done with gcc's constructor
+attribute. This mechanism will likely have to be changed for other compilers.
+
+register_extensions() loops over all local displays and screens, determines
+the DRI driver for each, and calls the driver's __driRegisterExtensions()
+function, if present.
+
+The __driRegisterExtensions() function can add new entrypoints to libGL
+by calling:
+
+ GLboolean _glapi_add_entrypoint(const char *funcName, GLuint offset)
+
+The parameters are the name of the function (such as "glFoobarEXT") and the
+offset of the dispatch slot in the API dispatch table. The return value
+indicates success (GL_TRUE) or failure (GL_FALSE).
+
+_glapi_add_entrypoint() will synthesize entrypoint code in assembly
+language. Assembly languages is required since parameter passing
+can't be handled correctly using a C-based solution.
+
+The address of the new entrypoint is obtained by calling the
+glXGetProcAddressARB() function.
+
+The dispatch offset number MUST be a number allocated by SGI in the same
+manner in which new GL_* constants are allocated. Using an arbitrary
+offset number will result in many problems.
+
+
+
+Dispatch Management
+
+When a GL context is made current, the driver must install its dispatch
+table as the current dispatch table. This is done by calling
+
+ void _glapi_set_dispatch(struct _glapi_table *dispatch);
+
+This will install the named dispatch table for the calling thread.
+The current dispatch table for a thread can be obtained by calling
+
+ struct _glapi_table *_glapi_get_dispatch(void);
+
+For higher performance in the common single-thread case, the global
+variable _glapi_Dispatch will point to the current dispatch table.
+This variable will be NULL when in multi-thread mode.
+
+
+
+Context Management
+
+libGL.so uses the XFree86 xthreads package to manage a thread-specific
+current context pointer. See __glXGet/SetCurrentContext() in glext.c
+
+Drivers may use the _glapi_set/get_context() functions to maintain
+a private thread-specific context pointer.

+<pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
+US$10,000 to the Mesa project to support its continuing development.
+Mesa is a free implementation of the OpenGL 3D graphics library and id's
+newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
+
+The donation will go to Keith Whitwell, who has been optimizing Mesa to
+improve performance on 3d hardware. Thanks to Keith's work, many
+applications using Mesa 3.1 will see a dramatic performance increase
+over Mesa 3.0. The donation will allow Keith to continue working on
+Mesa full time for some time to come.
+
+For more information about Mesa see www.mesa3d.org. For more
+information about id Software, Inc. see www.idsoftware.com.
