Hello, I’m a student studying embedded systems.
Recently I tried to check memory bandwidth on jetson tx2 and figured out that I can use PMU counters by reading/writing some system registers.
However i can’t tell that if the values that counters gave me include memory accesses from GPU, ethernet, etc.
I’m not that good at hardwares, so understanding datasheet was a very hard work for me…
this is the reference manual I used.
used pmu event : BUS_ACCESS
