From 7085c11e493e5a7bbe56a602a3252f4e28c2f974 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Wed, 22 Feb 2012 17:30:56 +0100 Subject: EGL Display Lifecycle Robustness Patch (impl. workaround) Added EGLDisplayUtil helper class managing the lifecycle of the EGL display handle recursively. This class is required, due to implementation bugs within EGL where EGL.eglTerminate(long) does not mark the resource for deletion when still in use, bug releases them immediatly. This fixes unit test com.jogamp.opengl.test.junit.jogl.acore.TestInitConcurrentNEWT on Linux ARM w/ Omap4 and Tegra2. --- src/jogl/classes/jogamp/opengl/egl/EGLContext.java | 1 + .../classes/jogamp/opengl/egl/EGLDisplayUtil.java | 107 +++++++++++++++++++++ .../classes/jogamp/opengl/egl/EGLDrawable.java | 8 +- .../jogamp/opengl/egl/EGLDrawableFactory.java | 6 +- .../jogamp/newt/driver/android/AndroidDisplay.java | 6 +- .../classes/jogamp/newt/driver/kd/KDDisplay.java | 6 +- 6 files changed, 121 insertions(+), 13 deletions(-) create mode 100644 src/jogl/classes/jogamp/opengl/egl/EGLDisplayUtil.java (limited to 'src') diff --git a/src/jogl/classes/jogamp/opengl/egl/EGLContext.java b/src/jogl/classes/jogamp/opengl/egl/EGLContext.java index 308757416..9028f4377 100644 --- a/src/jogl/classes/jogamp/opengl/egl/EGLContext.java +++ b/src/jogl/classes/jogamp/opengl/egl/EGLContext.java @@ -1,5 +1,6 @@ /* * Copyright (c) 2008 Sun Microsystems, Inc.
