Re: Interrupt duration and WiFi
Does anyone have an idea? Without insight into the NIC and its driver it is very hard to find an answer to this question. Is there any possibility of checking weather the expected number of interrupts even occurs?

That is not the case, I get the same result wehen running everything on the same core.

Interrupt duration and WiFi
I am doing some tests to measure the maximum timing impact on my real-time application through wifi-packets. For this I wrote a monitoring task that regularly prints out the lateness of my task (that is the time it takes longer than it should to run). When I prioritize my observed task lower than th...

What ISR is called upon packet receive over WiFi?
Hey everyone, I was wandering if it is possible to see the code that is executed when a network packet is received by a NIC. I want to reconstruct the "way" a packet takes through the kernel until its payload is used by a user task. In the reference manuals I was only able to find programming models...

Re: Specification of ESP32 NIC
Hi, thanks for the responses so far. Yes, it has to do with interrupts that are generated by the NIC. I want to estimate the maximum "load" of interrupts the NIC produces under a very large number of incoming packets per second. It would be interesting to know if in fact a ring buffer is used and ho...

Specification of ESP32 NIC
Hi everyone, I am currently looking into NIC-generated interrupts at the ESP32. Unfortunately, I can't find any specific information about the wifi chip or its firmware. I am interested in information about the throwing of interrupts when packages arrive at the NIC. Are there interrupt moderation te...
