LTTng-UST for Zynq

Gidday there,

 

I have just watched an interesting talk about hardware assisted tracing and profiling at Embedded Linux Conference. I need to do some profiling of user-space code and was hoping to make use of these facilities on a Zynq-7020. However, it appears this may be problematic as described at the following wiki entry.

 

http://www.wiki.xilinx.com/LTTng+for+Xilinx+Zynq+Linux

 

"Userspace tracing(UST) is disabled from LTTng tools due to its dependencies to other libraries"

 

What are these dependencies? Is this simply a human resource issue or are there fundamental elements of the Zynq PS implementation that prevent UST?

 

Thanks in advance

 

Joshua
