From 4b77eee35fd243fff8df79dc80b905e91fd0fa42 Mon Sep 17 00:00:00 2001 From: Minsung Kim Date: Sat, 29 Nov 2014 21:43:53 +0900 Subject: [PATCH] cpufreq: interactive: don't skip waking up speedchange_task if target_freq > policy->cur When __cpufreq_driver_target() in speedchange_task failed for some reason, the policy->cur could be lower than the target_freq. The governor misses to change the target_freq if the target_freq is equal to the next_freq at the next sample time. Added a check to prevent the CPU to stay at the speed that is lower than the target_freq for long duration.
