From 6c0288655368f0decdf309ca4a90fc60cbc29378 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Fri, 19 Sep 2014 01:24:32 +0200 Subject: New GLRendererQuirks.BuggyColorRenderbuffer: On Mesa 7.2 software, FBO color renderbuffer may cause a crash Workaround crash caused by Mesa 7.2 software rendering using color renderbuffer target in FBO. If Mesa < 8.0 and software - or - property 'jogl.fbo.force.nocolorrenderbuffer' is set, set quirks: - GLRendererQuirks.BuggyColorRenderbuffer - GLRendererQuirks.NoFullFBOSupport (to disable MSAA) GLFBODrawable always uses FBOMODE_USE_TEXTURE if GLRendererQuirks.BuggyColorRenderbuffer is set. +++ Crash Report: GNU C Library : 2.13 stable OpenGL : software Operating System : Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 Processor ID : x86 Family 6 Model 44 Stepping 2, GenuineIntel Abnormal termination: Segmentation violation Register State (from fault): RAX = 00000000ff1818f0 RBX = 00000000beaf8afc RCX = 0000000000000004 RDX = 00007f85ed9c9010 RSP = 00007f8252d24fd0 RBP = 00007f8252d25020 RSI = 0000000017b9b330 RDI = 0000000015bca400 R8 = 0000000000000000 R9 = 00007f81edcd3014 R10 = 00007f823565f6ce R11 = 00007f827bee49aa R12 = 0000000000001406 R13 = 0000000000000001 R14 = 00000000154d5458 R15 = 00000000154d4f10 RIP = 00007f823565f7bc EFL = 0000000000010206 CS = 0033 FS = 0000 GS = 0000 Stack Trace (from fault): [ 0] 0x00007f823565f7bc put_row_ubyte4 at /mesa/main/renderbuffer.c:665 (in /lib/libGL.so.1) [ 1] 0x00007f8235727239 _swrast_write_rgba_span at /mesa/swrast/s_span.c:1450 (in /lib/libGL.so.1) [ 2] 0x00007f823574b071 smooth_rgba_triangle at /mesa/swrast/s_tritemp.h:862 (in /lib/libGL.so.1) [ 3] 0x00007f82357155f0 _swrast_Triangle at /mesa/swrast/s_context.c:692 (in /lib/libGL.so.1) [ 4] 0x00007f8235771780 triangle_offset_twoside_rgba at /mesa/swrast_setup/ss_tritmp.h:188 (in /lib/libGL.so.1) [ 5] 0x00007f82356d2cea _tnl_render_poly_elts at /mesa/tnl/t_vb_rendertmp.h:313 (in /lib/libGL.so.1) [ 6] 0x00007f82356d335e _tnl_RenderClippedPolygon at /mesa/tnl/t_vb_render.c:244 (in /lib/libGL.so.1) [ 7] 0x00007f82356c9313 clip_tri_4 at /mesa/tnl/t_vb_cliptmp.h:230 (in /lib/libGL.so.1) [ 8] 0x00007f82356cd026 clip_render_triangles_verts at /mesa/tnl/t_vb_rendertmp.h:163 (in /lib/libGL.so.1) [ 9] 0x00007f82356d37d9 run_render at /mesa/tnl/t_vb_render.c:320 (in /lib/libGL.so.1) [ 10] 0x00007f82356c2436 _tnl_run_pipeline at /mesa/tnl/t_pipeline.c:158 (in /lib/libGL.so.1) [ 11] 0x00007f82356c37da _tnl_draw_prims at /mesa/tnl/t_draw.c:402 (in /lib/libGL.so.1) [ 12] 0x00007f82356b673a vbo_exec_DrawArrays at /mesa/vbo/vbo_exec_array.c:263 (in /lib/libGL.so.1) [ 13] 0x00007f823583e5b0 glDrawArrays at /mesa/glapi/glapitemp.h:1645 (in /lib/libGL.so.1) +++ --- src/jogl/classes/jogamp/opengl/GLFBODrawableImpl.java | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'src/jogl/classes/jogamp/opengl/GLFBODrawableImpl.java') diff --git a/src/jogl/classes/jogamp/opengl/GLFBODrawableImpl.java b/src/jogl/classes/jogamp/opengl/GLFBODrawableImpl.java index 0d871017e..f3954b7b6 100644 --- a/src/jogl/classes/jogamp/opengl/GLFBODrawableImpl.java +++ b/src/jogl/classes/jogamp/opengl/GLFBODrawableImpl.java @@ -15,6 +15,7 @@ import com.jogamp.common.util.PropertyAccess; import com.jogamp.common.util.VersionUtil; import com.jogamp.nativewindow.MutableGraphicsConfiguration; import com.jogamp.opengl.FBObject; +import com.jogamp.opengl.GLRendererQuirks; import com.jogamp.opengl.FBObject.Attachment; import com.jogamp.opengl.FBObject.Colorbuffer; import com.jogamp.opengl.FBObject.TextureAttachment; @@ -44,7 +45,7 @@ public class GLFBODrawableImpl extends GLDrawableImpl implements GLFBODrawable { static { Debug.initSingleton(); DEBUG = GLDrawableImpl.DEBUG || Debug.debug("FBObject"); - DEBUG_SWAP = DEBUG || PropertyAccess.isPropertyDefined("jogl.debug.FBObject.Swap", true); + DEBUG_SWAP = PropertyAccess.isPropertyDefined("jogl.debug.FBObject.Swap", true); } private final GLDrawableImpl parent; @@ -198,6 +199,12 @@ public class GLFBODrawableImpl extends GLDrawableImpl implements GLFBODrawable { fboIBack = 0; // head fboIFront = fbos.length - 1; // tail + if( 0 == ( FBOMODE_USE_TEXTURE & fboModeBits ) && + gl.getContext().hasRendererQuirk(GLRendererQuirks.BuggyColorRenderbuffer) ) { + // GLRendererQuirks.BuggyColorRenderbuffer also disables MSAA, i.e. full FBO support + fboModeBits |= FBOMODE_USE_TEXTURE; + } + final boolean useTexture = 0 != ( FBOMODE_USE_TEXTURE & fboModeBits ); final boolean useDepth = 0 != ( FBOMODE_USE_DEPTH & fboModeBits ); final boolean useStencil = chosenFBOCaps.getStencilBits() > 0; -- cgit v1.2.3
