How to get the interrupts(include SEIs, SGIs and so on) when an application running on TDA4VM?

Are there some APIs that can get the begin/end of the interrupt?

And are there some APIs that can distinguish the type of the interrupt?

Hi,

Can you please add more details here?

In general the number of interrupts can be counted by adding a global variable in the Interrupt Service Routines.

How to get the start/stop of the interrupts? Are there some API or some example?

I did not get the question, what do you mean by start/stop of interrupts? Do you want to know when the interrupt has hit? There are VIM status registers for that.

Regards,

For example, Thread A runs on the core1, a higher priority thread B is scheduled on core1, an interrupt is generated. I want to collect the timestamp or clock to start to handle interrupt, the timestamp or clock to complete processing interrupt, and the handle was generated if possible.

Which function indicates interrupt start processing and Which function indicates that interrupt processing has completed?
Is HwiP_enableInterrupt means start and HwiP_disableInterrupt means stop? or other APIs?
