opengl program crashes radeon driver

hi,

I've written a program for a school presentation which simulates a magnetic pendulum. I use OpenGL for calculating and rendering the basins. To keep it short: I can calculate with different precisions. The more precise the calculation should be, the more time the shader program needs to finish. But when the shader program needs to much time my radeon driver crashes
here is the dmesg output

Re: opengl program crashes radeon driver

Though I am of NO HELP on this issue, I would think posting your code might help troubleshoot things. There are experts here that could at least see if it's an obvious coding problem or maybe even test it on their own machines.

Re: opengl program crashes radeon driver

I don't think you understand what a "tainted kernel" is. Try looking it up with google.

Re: opengl program crashes radeon driver

I had to reread your original post a few times...

when the shader program needs to much time Xorg crashes.

THIS is the real problem, right? Why is your software causing Xorg to crash? Is it eating up all your memory or something?

My program is causing the radeon module to crash, and the radeon module causes Xorg to crash. But a userspace program shouldn't be able to crash a kernel module.

Re: opengl program crashes radeon driver

It might be a bug in the driver and it should be reported upstream. Given that you have a way to reliably trigger the problem, your magnetic pendulum simulation code, it should be relatively easy to get someone to look at the problem assuming you can share your code.
