Determining HWI/SWI/kernel stack usage on the runtime

Adam Turowski

Hi all,

I am using DSP/BIOS 5.41.03.17 on OMAPL-138 and would like to find out how much HWI/SWI/kernel stack is being used. I've managed to do that for tasks' stacks by using TSK_checkstacks function from DSP/BIOS TSK module, but didn't found similar mechanism for HWI/SWI/kernel stack. Is there such a method available?

Best regards,

Adam

Hi Adam,

There are no runtime APIs in DSP/BIOS to determine system stack usage. You can use ROV to determine system stack usage.

For determining task stack usage you can use TSK_stat() runtime API.

Hi Ashish,

Thank you for coming back to me. Unfortunately in my application I can't use KOV and have to stick to implementing checks in DSP runtime code. I could replicate system stack usage checking KOV functionality in my runtime code, but need some details regarding how KOV does that. Can you provide me with these details please?

Best regards,

Adam

Hi Adam,

Look at getStackPeak() function implementation in the attached file:
