My kernel crashes Kernel Analyzer badly.

I have a kernel that completely crashes the Kernel Analizer ...

Re: My kernel crashes Kernel Analyzer badly.

Hi Bubu,

By kernel analyzer -- Do you mean the one from CodeXL?

(or)
Are you talking about the legacy kernel analyzer, which is no more supported?

Best Regards,

Sarnath

Re: My kernel crashes Kernel Analyzer badly.

The Kernel analyzer 2.1.880, which I use to precompile the kernels in order to load faster the kernels and to hide a bit my source code.

Re: My kernel crashes Kernel Analyzer badly.

Sorry, kernelAnalyzer software is not supported. I dont even know what dependencies it has with the driver versions...

If you can reproduce the problem with CodeXL and the Latest drivers, I can lodge a bug report - provided you give me a repro-case.

Try stripping down the code to a bare minimal until it does not crash... As you iterate through this process -- you can probably find that code fragment which is doing it down... So, then -- you can build a very minimal repro-case for us to handle this problem.

Best Regards,

Bruhaspati

Re: My kernel crashes Kernel Analyzer badly.

Can CodeXL precompile kernels? The idea was to use the KA2 to precompile my kernels because I don't want to redist my source code ...

Re: My kernel crashes Kernel Analyzer badly.

I dont know if CodeXL can... But you can use clGetProgramInfo() to get binaries and store them in a file.

At run-time, you can use clCreateProgramWithBinary() which you already are doing I believe....

But yes, this would require the device in place...

Can KA2 compile kernels for any device (without the device being physically insalled?)
