* egl: Add checks for EGL_MESA_screen_surface.Chia-I Wu2010-07-3110-21/+91
| | | | | This allows Mesa EGL to be compiled with eglext.h that does not define EGL_MESA_screen_surface.
* egl: Fix deref before NULL-checkKristian Høgsberg2010-07-281-1/+2
|
* egl: EGL_KHR_surfaceless_* extensionsKristian Høgsberg2010-07-284-36/+67
| | | | | | | | | 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.
* egl: Return the correct array size in _eglFlattenArray.Chia-I Wu2010-07-151-1/+4
| | | | | | | 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.
* egl: Remove unnecessary headers.Vinson Lee2010-07-062-2/+0

* egl: Rework driver loading.Chia-I Wu2010-07-067-211/+365
| | | | | | | | | | | | | | | 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.
* egl: Always use EGLAPIENTRY in api function prototypesnobled2010-07-031-15/+15
| | | | Fixes the build on Windows.
* egl: Update MaxSize when a dynamic array is grown.Chia-I Wu2010-06-301-0/+1
|
* egl: Make _eglUnloadDrivers no-op on Windows.Chia-I Wu2010-06-301-0/+4
| | | | | Windows unloads DLLs before atexit. Make _eglUnloadDrivers no-op on Windows for now.
* egl: Store screens in a dynamic array.Chia-I Wu2010-06-303-30/+31
|
* egl: Store configs in a dynamic array.Chia-I Wu2010-06-303-53/+26
|
* egl: Add dynamic array.Chia-I Wu2010-06-305-0/+217
| | | | Dynamic arrays will be used to store configs and screens of a display.
* egl: Remove st/egl probe code.Chia-I Wu2010-06-292-56/+0
| | | | It is no longer needed.
* egl: Do not call drv->Initialize with global mutex locked.Chia-I Wu2010-06-291-3/+9
|
* st/egl: Build a single EGL driver.Chia-I Wu2010-06-291-82/+3
| | | | | | | | | | | | 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.
* st/egl: One driver per hardware.Chia-I Wu2010-06-296-45/+66
| | | | | | 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.
* egl: Add support for EGL_MESA_drm_display.Chia-I Wu2010-06-233-0/+16
| | | | | | | 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.
* egl: Introduce platform displays internally.Chia-I Wu2010-06-237-8/+61
| | | | | | | | | | | 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.
* egl: s/EGL_DISPLAY/EGL_PLATFORM/.Chia-I Wu2010-06-172-11/+14
| | | | | A platform is already used to mean a window system in EGL. No need to use a different term.
* egl: s/_EGL_PLATFORM/_EGL_OS/ and s/POSIX/UNIX/.Chia-I Wu2010-06-174-15/+15
| | | | | A platform means a native window system in EGL. Use OS that follows Gallium instead.
* egl: Use SConscript for Windows build.Chia-I Wu2010-05-317-9/+72
| | | | Fix several portability issues and add SConscript for Windows build.
* Define PUBLIC to dllexport on MSVC.Chia-I Wu2010-05-311-4/+8
| | | | Define PUBLIC to __declspec(dllexport) when _MVC_VER is defined.
* Always define int32_t in compiler headers.Chia-I Wu2010-05-311-3/+1
| | | | eglplatform.h no longer defines int32_t.
* egl: Return NULL if we fail to load a default driverKristian Høgsberg2010-05-271-1/+1
|
* egl: Implement EGL_NOK_texture_from_pixmapKristian Høgsberg2010-05-146-11/+48
| | | | | | | 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.
* egl: Only allow valid config attributes in _eglParseConfigAttribList()Kristian Høgsberg2010-05-141-28/+24
| | | | Passing 0x3030, 0 in the chooser list didn't get caught.
* egl: Silence uninitialized variable warnings.Vinson Lee2010-05-141-1/+1
|
* egl: Implement EGL_NOK_swap_regionKristian Høgsberg2010-05-134-0/+41
| | | | | | | | | 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.
* egl: Allow a prioritized list of default driversKristian Høgsberg2010-05-136-26/+45
| | | | | | | | | | | | | | 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.
* egl: Drop broken _EGL_PLATFORM_NO_OS codeKristian Høgsberg2010-05-131-32/+0
| | | | | It would do strlen(library_suffix()) in _eglLoaderFile(), with library_suffix() returning NULL. So obviuosly not used or tested.
* egl: Don't try to load driver basename if the platform needs a suffixKristian Høgsberg2010-05-131-3/+5
| | | | That is, don't dlopen(egl_glx) when we know we need to append .so.
* egl: Add _eglSearchPathForEach.Chia-I Wu2010-05-082-0/+20
| | | | The function can be used by a driver to check each search path of EGL.
* Add egl.pc fileKristian Høgsberg2010-05-042-1/+30

* Merge branch '7.8'Dan Nicholson2010-04-191-1/+1
|\ | | | | | | | | | | | | | | Conflicts: progs/egl/Makefile progs/egl/Makefile is gone on master with the egl demos split into subdirectories. Will require an additional commit.
| * egl: Pass flags to locate Xlib headers and librariesDan Nicholson2010-04-191-1/+1
| | | | | | | | | | | | | | | | eglplatform.h pulls in Xlib.h on X11 platforms. Likewise, the egl glx driver and egl programs needs to link to libX11. Make sure we use the locations the user told us about. Signed-off-by: Dan Nicholson <[email protected]>
* | egl: Unbind the old context in _eglBindContext.Chia-I Wu2010-04-061-10/+9
| | | | | | | | The last commit incorrectly moved the code under an "else".
* | egl: Fix eglMakeCurrent with different surfaces.Chia-I Wu2010-04-061-30/+45
| | | | | | | | | | | | 0a82fadcdd0b6ebbc345c7c302da0e0efce40a98 seems to trigger a bug in _eglBindContext. Rework the logics yet again. It is simpler, and hopefully correct this time.
* | egl: Make _eglBindContextToSurfaces more readable.Chia-I Wu2010-03-281-11/+25
| | | | | | | | | | | | 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.
* | egl: Always return the previously bound context.Chia-I Wu2010-03-281-9/+8
|/ | | | | | 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.
* Remove support for GCC older than 3.3.0Ian Romanick2010-03-031-3/+2
| | | | Signed-off-by: Ian Romanick <[email protected]>
* egl: Remove unused _EGL_SKIP_HANDLE_CHECK.Chia-I Wu2010-02-234-53/+0
| | | | | | 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.
* egl: Silence warnings when compiled with -pedantic.Chia-I Wu2010-02-194-4/+10
| | | | Just follow gcc's advices here.
* egl: Silence warnings in check/return macros.Chia-I Wu2010-02-191-139/+147
| | | | | | 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.
* egl: Revisit global data locking.Chia-I Wu2010-02-174-8/+23
| | | | | Lock the global mutex in _eglPreloadDrivers and _eglAllocScreenHandle. Add comments to why certain pathes do not need locking.
* egl: Always lock a display before using it.Chia-I Wu2010-02-172-45/+81
| | | | | | | 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.
* egl: Make eglGetDisplay atomic.Chia-I Wu2010-02-173-103/+22
| | | | | Merge _eglNewDisplay and _eglLinkDisplay into _eglFindDisplay. Remove unused _eglUnlinkDisplay.
* egl: Add a mutex to _EGLDisplay.Chia-I Wu2010-02-172-0/+4
| | | | | A display may be shared by multiple threads. Add a mutex for access control.
* egl: eglGetError should return the status of the last call.Chia-I Wu2010-02-171-123/+226
| | | | | | 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.
* egl: Always record error code.Chia-I Wu2010-02-171-4/+5
| | | | | The error code denotes the success or failure of the most recent function call. A call to _eglError should always update the error code.
* egl: Use new error checking macros.Chia-I Wu2010-02-171-115/+110
| | | | Replace all uses of _EGL_DECLARE_* and _eglCheck* by _EGL_CHECK_*.
