In nvhost_pod_estimate_freq(), we return GET_TARGET_FREQ_DONTSCALE if new frequency is same as current frequency And based on this return value, update_devfreq() will just return without actually calling target() function But it is possible that target() function has freq clipping of its own, and skipping target() itself will break this Hence in case we find new frequency same as current frequency, do not return GET_TARGET_FREQ_DONTSCALE Instead just return 0 Note that we still return GET_TARGET_FREQ_DONTSCALE if governor itself is disabled, and this is required in perf measurement cases Bug 200245796 Change-Id: I55a3a344982c5b5441ba011cd0dd254947e89e5c Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1251841 (cherry picked from linux-4.9 commit c6417ac88eb43501b8bf6d5351059ac2dadaf2c0) Reviewed-on: https://git-master.nvidia.com/r/1770145 Reviewed-by: Mikko Perttunen <mperttunen@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Timo Alho <talho@nvidia.com> Tested-by: Timo Alho <talho@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
