I am trying to use the PERF tools and when I use the commands that depend on the PERF events I got the following error message :

"Error: File /sys/kernel/debug/tracing/events/sched/sched_wakeup not found.
Hint: Perhaps this kernel misses some CONFIG
setting to enable this feature?. "

Also both of those option are activated
-CONFIG_HAVE_PERF_EVENTS=y
-CONFIG_PERF_EVENTS=y
And
I Added to the yocto "local.conf" :
-INHIBIT_PACKAGE_STRIP = "1"
-EXTRA_IMAGE_FEATURES= "debug-tweaks tools-debug dbg-pkgs tools-profile"
-PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'

Are the PERF events supported or what I did wrong ?
