Perf not working properly on Tegra

[brian103]

Perf compiling but giving me mangled function names.

Followed instructions here to build tegra: Installing Linux performance monitoring tools on Jetson TX2

Also installed basically every library used to enable function mangling including libiberty and binutils. As recommended here: c++ - Perf shows mangled function names - Stack Overflow

Not even truly clear what that is. Is this a feature that’s just not available on the jetson?

Hi brian103,

Please download Driver Package Sources from: Jetson Linux R32.7.1 Release Page | NVIDIA Developer
Steps:
Copy “kernel_src.tbz2” to TX2
$ cd kernel/kernel-4.9/tools/perf
$ make
$ ./perf --version
perf version 4.9.253
