RE: Unable to schedue bottom halve

Hi Srinivas,

 

Spinlocks aren’t a problem even in interrupt context.

 

I am not sure why you are getting in_interrupt to non-zero for work queues? In process context we should have in_interrupt returning 0.

 

Thanks,

Vishwas

However are you taking some semaphore/scheduling, while in_interrupt is true?

 

i checked this in_interrupt() in the handler i.e my work that is queued (bottom half) which ideally should not be any positive value since it is not running in interrupt context. however i see it returns a positive value.

 

ya i do take spinlock. it should not be a problem right since we have the context now !!! with work queues.

Srinivas
