Good morning,

Hi,

I am focusing on OpenCSD library and looking for information about the difference between OpenCSD and CSAL library. As I noticed, CSAL is for interacting directly with CoreSight trace devices on target and programing the tracers while OpenCSD is for collecting the trace and decode it. Is there any other information you can provide me ?

Have you ever accessed to OpenCSD github [1]? Probably you can get more information about OpenCSD from there.

I'm not familiar with CSAL though, I can forward an Mike's email in which he introduced a lot about that library.

I suggest you to cc coresight mail list when you have some question about CoreSight. There is a lot of knowledgeable people on there.

Good morning,

Hi,

I am doing an internship at STMicroelectronics and I am new to decoding traces. I just red your article entitled "System Trace Module (STM) and its usage" and the article "HOWTO-using the library with perf" and started working on System Trace Module. Unfortunately, I can't find stm_source directory. Is it only available on certain Kernel versions ?

Yes, those patches got merged in v4.10-rc1, and you have to ensure 'STM_SOURCE_FTRACE' is selected when compiling the kernel code.
