Does anyone know how to enable systraces on the 12.2? I get "error opening /sys/kernel/debug/tracing/options/print-tgid: Permission denied (13)
" everytime I run systrace. Seems like systrace is not activated in the kernel. I need systrace to improve performance for an app that I'm writing for the Note series of tablets.
