[Question] ETM data loss due to limited buffer size of sink device

by liuqi (BA)

Hi Mathieu & Suzuki, Here is a question about the amount of data traced by ETM device. In high-CPU-utilization scene, volume of ETM trace data may be very large, but limited buffer in sink device which is used to store trace data can not hold all of these data. It seems that data loss in sink device is inevitable. So how could we ensure the data we are interested in isn't lost, or what we can do to reduce this kind of data loss? Any response will be highly appreciated. Thanks, Qi

Missing cs-trace-disasm.py

by Szymanski, Pawel

Hello, I am trying to run trace capturing from Coresight on N1 SDP using perf as described here: https://github.com/Linaro/OpenCSD/blob/master/HOWTO.md I was able to gather the traces, but when I wanted to get the python script to get more human readable output as described in section https://github.com/Linaro/OpenCSD/blob/master/HOWTO.md#trace-decoding-with-…, I found that the cs-trace-disasm.py Is missing in my system. Do you know where I can find the file? Regards Pawel Intel Technology Poland sp. z o.o. ul.
