I was tying to use perf
on Renesas target and I configured the yocto "local.conf" as showed in this link.
#avoid stripping binaries
INHIBIT_PACKAGE_STRIP = "1"
#add the debug information
EXTRA_IMAGE_FEATURES= "debug-tweaks tools-debug dbg-pkgs tools-profile"
#format the debug info into a readable format for PERF
PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'
perf
is working but I need to monitor the context switches which require to use perf timechart
and other commands that depends on perf-events, but the commands can't find this path "/sys/kernel/debug/tracing/events" .
What should I do in order to get this folder and its files compiled with my kernel?
