In my opinion it is not a good setting from following reasons:
on one side you decreased core 1,2 and 3 max frequencies
Code:
scaling_max_freq_cpu0=1890000
scaling_max_freq_cpu1=1458000
scaling_max_freq_cpu2=1134000
scaling_max_freq_cpu3=1134000
but you left the scaling to higher frequencies in hotplug settings:
Code:
hotplug_freq_1_1=1242000
hotplug_freq_2_0=810000
hotplug_freq_2_1=1566000
hotplug_freq_3_0=918000
hotplug_freq_3_1=1674000
hotplug_freq_4_0=918000
So at least your hotplug will not be working correctly. ... if you want I can do you similar profile but with these problems fixed ... I see your settings are very conservative and aiming to be power saving to be used mostly as mp3 (not sure about more demanding games - I am sure you must have problems with the AA titles).
