Subject: [PATCH 1/1] sched: Add update_rq_clock() in sched_rt_rq_enqueue()
Date: Fri, 24 Dec 2021 09:22:39 +0800 [thread overview]
Message-ID: <20211224012239.4694-1-yt.chang@mediatek.com> (raw)
Add update_rq_clock() in sched_rt_rq_enqueue() to
prevent the warning "rq->clock_update_flags < RQCF_ACT_SKIP"
when call rq_clock() in cpufreq_update_util().
sched_rt_rq_enqueue ->
enqueue_top_rt_rq ->
cpufreq_update_util ->
rq_clock ->
assert_clock_updated
