[LITMUS^RT] Feather Trace tools

[Chandrasekaran Sivakumar]

Hi,

I couldnt find ft_trace device in /dev/litmus. These options were not
available when I did 'make menuconfig'

LITMUS^RT > Tracing > Feather-Trace Infrastructure (CONFIG_FEATHER_TRACE)
LITMUS^RT > Tracing > Record timestamps for overhead measurements
(CONFIG_SCHED_OVERHEAD_TRACE)
LITMUS^RT > Tracing > Buffer size for Feather-Trace overhead data
(CONFIG_SCHED_OVERHEAD_TRACE_SHIFT)

So I checked litmus/litmusrt/Kconfig..
It had only this,

#
# For a description of the syntax of this configuration file,
# see Documentation/kbuild/kconfig-language.txt.
#
mainmenu "Linux/$ARCH $KERNELVERSION Kernel Configuration"

config SRCARCH
string
option env="SRCARCH"

source "arch/$SRCARCH/Kconfig"

Am I looking at the wrong file ?

Regards,
chandru
