AM335x interrupt latency performance

Dear sirs,

Could you explain what's the meaning of number of samples in interrupt latency measurement in Processor_SDK_Linux_Kernel_Performance_Guide?

Hi,

It's not very clear at first sight, but this shows how many of the total samples (1001, resp. 501) fall into the given time interval. For example the first row shows that 25 out of 1001 interrupts (respectively 0 out of 501) have 10us latency.
