* egl: Add debug messages to config validation and matching.Chia-I Wu2010-02-051-2/+23
| | | | It might be desirable find out which attribute went wrong.
* egl: Clean up eglconfig.h.Chia-I Wu2010-02-051-14/+7
| | | | | Update the comments to macros/functions. Remove unused _eglSetConfigAttrib.
* egl: Update the comments to typecast macros.Chia-I Wu2010-02-051-0/+6
| | | | | Put a note that the macros define functions and should not be ended with a semicolon when used.
* egl: Clarify IsLinked and IsBound.Chia-I Wu2010-02-052-0/+12
| | | | | | 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.
* egl: Add macros to define typecast functions.Chia-I Wu2010-02-041-0/+21
| | | | | | | | | | 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.
* egl: fix wrong argument. Use loader_data instead of loaderIgor Oliveira2010-02-041-1/+1
|
* egl: Rename _eglPreloadForEach callbacks.Chia-I Wu2010-02-031-12/+12
| | | | | | | 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: Fix a potential segfault in driver suffix matching.Chia-I Wu2010-02-031-3/+5
| | | | | The driver suffix might be NULL on some platforms. Perform the matching only when there is a suffix.
* egl: Remove unnecessary #ifdef's.Chia-I Wu2010-02-031-8/+0
| | | | | There were some refactorings with the addition of EGL_DRIVERS_PATH. They made some platform #ifdef's unnecessary.
* egl: Ignore certain environment variables when setuid/setgid.Chia-I Wu2010-02-031-2/+16
| | | | | Specifically, ignore EGL_DRIVERS_PATH when an application is setuid/setgid. And ignore EGL_DRIVER when there is a slash in it.
* egl: Add EGL_DRIVERS_PATH environment variable.Chia-I Wu2010-02-031-99/+191
| | | | | | | | | 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.
* egl: Remove unnecessary headers.Vinson Lee2010-01-313-3/+0
|
* egl: Clean up surface attributes.Chia-I Wu2010-01-313-57/+127
| | | | | | 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.
* egl: Add support for more EGLImage extensions to EGL core.Chia-I Wu2010-01-314-11/+60
| | | | | | 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: Surface type validaction should depend on extensions supported.Chia-I Wu2010-01-311-1/+2
| | | | | EGL_SCREEN_BIT_MESA is a valid bit only when EGL_MESA_screen_surface is supported.
* egl: Initialize display configs with the display.Chia-I Wu2010-01-312-3/+5
| | | | This changes _eglInitConfig to take the display as its argument.
* egl: Initialize display resources with their display.Chia-I Wu2010-01-316-7/+10
| | | | | | | 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.
* egl: Refactor _eglInitImage.Chia-I Wu2010-01-311-10/+40
| | | | Refactor attribute list parsing code to _eglParseImageAttribList.
* egl: Refactor _eglInitContext.Chia-I Wu2010-01-311-19/+95
| | | | | Refactor attribute list parsing code to _eglParseContextAttribList. Add a check to make sure the config supports the client API.
* egl: Refactor _eglInitSurface.Chia-I Wu2010-01-311-141/+146
| | | | Refactor attribute list parsing code to _eglParseSurfaceAttribList.
* egl: Remove code blocks that are commented out.Chia-I Wu2010-01-314-113/+4
| | | | | | 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.
* egl: Remove my_strdup.Chia-I Wu2010-01-301-17/+2
| | | | There is already _eglstrdup for the main library's use.
* egl: Remove unused VisibleRefCount.Chia-I Wu2010-01-301-3/+0
|
* egl: Rename Binding to CurrentContext in _EGLSurface.Chia-I Wu2010-01-302-15/+15
| | | | | A context can be bound to a surface just like it can be bound to a thread. CurrentContext is a more consistent name.
* egl: Clean up header inclusions.Chia-I Wu2010-01-3022-19/+26
| | | | Mainly to remove eglcurrent.h and egldisplay.h from eglglobals.h.
* egl: Remove unnecessary headers.Vinson Lee2010-01-285-5/+0
|
* egl: Migrate drivers to use _eglBindContext.Chia-I Wu2010-01-282-22/+3
| | | | | _eglMakeCurrent is a big hammer that is not easy to use. Migrate drivers to use _eglBindContext and un-export _eglMakeCurrent.
* egl: Correctly unbind contexts in eglReleaseThread.Chia-I Wu2010-01-281-0/+4
| | | | | MakeCurrent unbinds the current context of the current API. Modify the current API to make sure all contexts are correctly unbound.
* egl: eglMakeCurrent should accept an uninitialized display.Chia-I Wu2010-01-283-15/+27
| | | | | | 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.
* egl: Add _eglBindContext.Chia-I Wu2010-01-282-53/+74
| | | | | | It works similar to _eglMakeCurrent, except that the old context and surfaces are returned instead of destroyed. _eglMakeCurrent is now calling the new _eglBindContext.
* egl: Use a boolean to indicate whether a display is initialized.Chia-I Wu2010-01-282-16/+20
| | | | | | 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.
* egl: Remove _eglOpenDriver and _eglCloseDriver.Chia-I Wu2010-01-263-32/+4
| | | | | _eglCloseDriver is no-op and _eglOpenDriver does nothing but call _eglMatchDriver. Export _eglMatchDriver directly.
* egl: Fix a segfault when a display is initialized again.Chia-I Wu2010-01-261-0/+1
| | | | Reset dpy->MaxConfigs so that dpy->Configs is re-allocated.
* egl: Remove _eglGetCurrentSurface and _eglGetCurrentDisplay.Chia-I Wu2010-01-263-47/+2
| | | | | They have little use in drivers since drivers need to work for multiple current contexts.
* egl: Fix leaks in eglReleaseThread.Chia-I Wu2010-01-261-6/+13
| | | | There may be multiple bound contexts that should be unbound.
* egl: Refactor _eglMakeCurrent.Chia-I Wu2010-01-261-78/+158
| | | | | Refactor _eglMakeCurrent into _eglCheckMakeCurrent, _eglBindContextToSurface, and _eglBindContextToThread.
* egl: Add _eglGetAPIContext.Chia-I Wu2010-01-262-1/+16
| | | | It will return the currently bound context of the given API.
* egl: Use a boolean to indicate whether a resource is linked.Chia-I Wu2010-01-262-2/+10
| | | | | | 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.
* egl: Mark _eglCheckResource as PUBLIC.Chia-I Wu2010-01-261-1/+1
| | | | | To support extensions such as GL_OES_EGL_image, the drivers need a way to check if a given EGLImageKHR is valid.
* egl: Native types are renamed in EGL 1.3.Chia-I Wu2010-01-256-17/+17
| | | | Rename Native*Type to EGLNative*Type.
* egl: Make resource void pointer in _eglCheckResource.Chia-I Wu2010-01-255-11/+11
| | | | | This emphasizes the fact that the resource to be checked could really be invalid and have an unknown type.
* egl: Install EGL headers.Chia-I Wu2010-01-251-1/+9
| | | | Install EGL (and KHR) headers along with the library.
* egl: Add support for EGL_KHR_image.Chia-I Wu2010-01-259-1/+233
| | | | Individual drivers still need to implement the API hooks.
* egl: Update headers.Chia-I Wu2010-01-252-3/+5
| | | | | | Update to the current versions found at http://www.khronos.org/registry/egl/. There is one modification in khrplatform.h for GCC visibility.
* egl: Add and use make_library_path.Chia-I Wu2010-01-241-27/+49
| | | | | | 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.
* egl: Remove _eglFindAPIs.Chia-I Wu2010-01-242-56/+0
| | | | | This function is not used and should have been removed by last commit. My mistake.
* egl: Remove unused helper functions.Chia-I Wu2010-01-242-217/+0
| | | | | _eglFillInConfigs and _eglFindAPIs have no user in Mesa and are unlikely to find one soon. It should be fine to remove them.
* egl: Remove unused casting functions.Chia-I Wu2010-01-241-21/+0
| | | | _eglUIntToPointer and _eglPointerToUInt are no longer used.
* egl: Make surfaces and contexts resources.Chia-I Wu2010-01-248-220/+78
| | | | | Turn _EGLSurface and _EGLContext into _EGLResource so that they can be managed uniformly.
* egl: Add _EGLResource and _EGLResourceType.Chia-I Wu2010-01-243-0/+113
| | | | | | Resources are objects managed by a display. They can be linked to or unlinked from a display. It is also possible to check if a resource is valid.
