API for condition wait

[psk1801]

Hi,

can any one suggest me which api I used for waiting for an condition wait instead of vmk_worldWait() , because system is crashed while using this api in Interrupt handler.

Error :

You cannot wait inside a BH or interrupt handler. Can you describe what problem you are trying to solve?

Thanks,

Hi chrklee.

I found the solution for the same.

the problem is while handling the interrupt , we are waiting to complete a task . But according  to document we can't wait while handling the interrupt. So we used vmk_HelperCreate api to avoid this problem.

I have another doubt , I implemented task management command for storage adapter , but I don't  know how to test. can you please help me for the same.

Thanks in advanced.
