2012-03-19Remove EGL context limit for Adreno GPUs.Jack Palevich
This change allows Adreno GPUs to have multiple EGL contexts. We had to limit this in earlier versions of Android due to limitations in the Adreno GPU driver (only 8 EGL contexts allowed system wide.) That brand of GPU has improved its EGL drivers to support multiple EGL contexts in more recent versions of their drivers used on more recent versions of Android.

2012-03-15Ignore EGL_BAD_CURRENT_SURFACE errors from eglSwapBuffersJack Palevich
Certain EGL device drivers are generating this error, so we need to survive it. (It's not clear from the EGL spec whether this is a legitimate error code, but since it's being generated we need to handle it.) Remove logging of expected errors from elSwapBuffers. We expect these errors to happen, and are handeling them by ignoring them. No need to clutter the logs. Bug: 6083241 Change-Id: If17dcfbb68d3009b92cf95a448728ccb47023b51

2011-11-16Add new ManagedEGLContext class to help apps participate in memory trimming.Dianne Hackborn
This class provides an API for an application to know when it is time to destroy its EGL context when memory is being trimmed. By having this in the framework, we can still detect whether it will be useful to destroy any EGL contexts (because we know if doing so will destroy all of them).

2011-11-15Fix potential GLThread / GLSurfaceView memory leak.Jack Palevich
Until now a leak was possible under the following scenario: Create a GLSurfaceView Register a renderer (this automatically starts a GLThread). Discard the GLSurfaceView without installing it in the view system. This scenario can occur when a device is rotated rapidly from orientation A to orientation B to orientation C. In that scenario, orientation B's GLSurfaceView might be discarded without ever being attached to a window. If this issue had been identified before GLSurfaceView had clients, one possible fix would have been to delay the construction of the GLThread until the GLSurfaceView was attached to a window. Unfortunately, it's too late, and so making that change would lead to observable changes in behavior, possibly breaking some clients. Instead, fixed by making GLThread and EGLHelper static classes that hold onto a weak reference to the GLSurfaceView. This allows the GLSurfaceView to be garbage collected when it is no longer used, even if the GLThread is active. GLSurfaceView's finalize method will manually stop the GLThread if it is still running when the GLSurfaceView exits. Part of this change was to remove the Renderer reference from GLThread, because Renderer is a user-supplied class that could contain a reference chain that points back to the GLSurfaceView. Fixes b/5606613 "GLSurfaceView that's never added to a window will leak threads and views, can leak activities" Change-Id: Iafdc329eb6e9e40062358e7c119f5547ffe23d5e

2011-08-01fix an issue where the screen could be stale after a surface size changeMathias Agopian
some GLES drivers dequeue buffers before a frame is started (which is allowed), which can cause a that frame to be rendered into a buffer of the wrong size. Such buffer will be ignored by the compositor. If the application draws only once after a size change, the screen might stay in this stale state. this can be avoided by telling the GL driver to purge all its pending buffers, which is done by making the surface not current and then current again. this solution is specific to android, but acceptable because handled solely in the framework.

2011-04-11Kill the global references in the OpenGL wrappers.Elliott Hughes
Just use jniThrowException instead. Note that it would be trivial to throw seemingly more appropriate exceptions (NullPointerException and OutOfMemoryException in particular), but I'm only attempting to preserve existing behavior here. I also found shadowing bugs in some of the special-case functions, which would previously always have leaked memory. This also moves an accidental change to a generated file (ActivityThread -> AppGlobals) into the generator, so it won't be overwritten in future. Change-Id: Iab570310b568cb406c60dd0e2b8211f8a36ae590

2010-07-13Fix deadlock when switching between two GLSurfaceViewsJack Palevich
Some devices only support a single active EGL context. On those devices, when a second activity that uses a GLSurfaceView is started in the same process, the second activity can potentially hang in GLSurfaceView.onWindowResize waiting for its GLSurfaceView render thread to draw a frame. The second activity's render thread is waiting to acquire an EGL context, but the first activity's render thread doesn't know it should release the EGL context. The fix is to detect the potential hang, and ask the first activity's render thread to release the EGL context. Change-Id: Ibb342c68772297744c973bcf5010581cd132db67

2010-04-19Quietly handle EGL_BAD_NATIVE_WINDOW errorsJack Palevich
We believe these errors happen when the window manager has told surface flinger to close the native window. If this error happens while we are creating the EGL surface we exit the render loop (and therefore exit the render thread.) If the error happens while swapping the surface we ignore it. In either situation, we expect that the application is about to be shut down by the window manager, so it should not be necessary to try and recover from the error.
2010-03-27Turn off logging.Jack Palevich
2010-03-25GLSurfaceView pause and resume now synchronizeJack Palevich
with the GLThread. We used to just set the mPaused state and return, now we wait until the rendering thread signals that it has noticed the change in pause state. This makes Pause/Resume more consistent with other UI-thread-to-GLThread event communication. This change was made in the hope of fixing some race conditions observed in monkey testing.

2010-03-24Improve our EGL management when pausing / resuming.Jack Palevich
We now release the EGL context when pausing. This is required to reduce the chance of running out of contexts on devices which support a limited number of active EGL contexts. Someday we may implement a global EGL context manager that will allow us to let EGL contexts persist until another activity needs an EGL context. But for now, without such a manager, we take the conservative approach. Separately, we now terminate EGL when pausing on Sapphire. This is a requirement of the Sapphire OpenGL driver.
