Hi all,
I've already reported this in bugzilla (bug# 3386). If I should have
reported this problem in this forum first, I apologise. I am happy to
debug this myself, if someone could please give me some pointers on how
to debug an active kernel module, and what I should look for first.
I am an experienced (though a little rusty) C/C++ developer, and have
installed all the development tools and debuggers I could find on the
distro.
The problem in summary: I have some java programs that use JOGL to drive
OpenGL but which cause a SIGSEGV in the r200 radeon driver. It is not at
all clear to me whether the problem is in the original java code, the
JOGL library, mesa, or the r200 driver. I have reported this to the JOGL
folk, and they have responded that I should report this to the DRI
forums. The problem currently makes ArtOfIllusion unusable for me with
OpenGL acceleration.
My 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)
My hardware:
DELL latitude D600 notebook with an ATI Mobility 9000 (M9) graphics card
I can reliably reproduce the crash by running the TestContextDestruction
demo from the JOGL website. (I can also produce a similar SIGSEGV with
the open source 3D modelling app "ArtOfIllusion" v2.1).
I have provided details on reproducing the JOGL demo error in bug report
#3386).
If someone could provide me with a few pointers on how to proceed, I am
happy to debug this further, and hopefully at least isolate the actual
problem location, even if I may not have the skills or knowledge to fix
that problem.
Cheers!
Nik.
