Summary: sigsegv in r200 when glXCreateContext called by JOGL
(Java for OpenGL)
Product: DRI
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I am encountering segsegv application crashes when I run the JOGL (Java for
OpenGL) demo TestContextDestruction.
Software:
updated (with YUM) Fedora Core 3 (kernel 2.6.11-1.14_FC3)
Xorg 6.8.2 (release date 9 February 2005)
radeon 4.0.1, ati 6.5.6,
drm 1.0.0 20040925.
Java: build 1.5.0_01-b08 (www.java.sun.com)
JOGL: binary build, 1.1b11 (May 11, 2005)
(https://jogl.dev.java.net/servlets/ProjectDocumentList?folderID=3336&expandFolder=3336&folderID=0)
Hardware:
DELL latitude D600 notebook with an ATI Mobility 9000 (M9) graphics card
I have a 100% reproducable testcase:
If I run the JOGL demo program TestContextDestruction, a sigsegv is thrown,
ironically in xGLCreateContext(). The TestContextDestruction demo can be
downloaded in the jogl-demos.jar download on the same page as the jogl
installation, or can be individually downloaded (single java file) from the jogl
project CVS.
I have also submitted a bug report to the JOGL project, but their belief is that
this is most likely a DRI r200 problem. Their response included: "JOGL stresses
the multithreading support of the driver more than most C applications."
To reproduce the crash, a java VM needs to be installed (I have 1.5) and the
JOGL libraries (1 java - jogl.jar, and 2 native libjogl.so, libjogl_cg.so) must
be installed as well (usually in <path-to-java>/jre/lib/ext (for jogl.jar) and
<path-to-java>/jre/lib/i386 (for jogl*.so)).
1a. If the demos are downloaded in binary form extract the jogl-demos.jar file
using "jar xvf jogl-demos.jar".
1b. If the source file was downloaded (say from CVS) then compile it using:
"javac -classpath .:<path-to->/jogl.jar -d . TestContextDestruction.java
2. run the program: "java demos.testContextDestruction.TestContextDestruction"
3. click on the "swap frame 1's and frame2's components" button twice.
The screen shows a summary of the crash, and names the log file (created in the
current directory) containing further information.
I am happy to provide any further information required.
The initial lines of the Java JVM-generated stack trace are included here, and I
will attach the entire file to this report.
