X-Git-Tag: v5.15~289^2~37
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1d8365a553a7caeb75246682b0901ce24a335602;p=platform%2Fkernel%2Flinux-starfive.git

tools/bootconfig: Support per-group/all event enabling option

Add group or all event enabling syntax support to bconf2ftrace.sh.
User can pass a bootconfig file which includes

ftrace[.instance.INSTANCE].event.enable

    and

ftrace[.instance.INSTANCE].event.GROUP.enable

correctly.
