Help with linux task schuduler at 4.18, please

[dukla2000]

on 4.4 when turning off CONFIG_ARM_ROCKCHIP_CPUFREQ and
setting CONFIG_ARM_BIG_LITTLE_CPUFREQ

I get the same cpu-core preference for  cpu4 and cpu5 (A72)

Is this set on your 4.19?

That is really interesting, thanks.

On both 4.18 and 4.18 I have tried both BIG_LITTLE_CPUFREQ and BL_CPUFREQ 

Code:

#
# CPU frequency scaling drivers
#
CONFIG_CPUFREQ_DT=y
CONFIG_CPUFREQ_DT_PLATDEV=y
# CONFIG_ACPI_CPPC_CPUFREQ is not set
CONFIG_ARM_BIG_LITTLE_CPUFREQ=y
CONFIG_ARM_DT_BL_CPUFREQ=y
# CONFIG_ARM_SCPI_CPUFREQ is not set
# CONFIG_QORIQ_CPUFREQ is not set
CONFIG_NET=y
CONFIG_NET_INGRESS=y

with no success. My thinking is that by now big.LITTLE is old enough that mainline support should be there. But I still cannot discover what I have "wrong".
