Linux 4.20 Scheduler To Better Deal With "Misfit" Tasks On ARM big.LITTLE Systems

2018-Oct-26 | Tags: COMSoCcompatibilitykernel

Linux on ARMThe next Linux kernel has scheduler improvements that will benefit some tasks when running on ARM big.LITTLE type systems where select CPU cores are more much more powerful than the other cores.

With the scheduler updates for the Linux 4.20~5.0 kernel, the kernel will now better migrate CPU-intense tasks on asymmetric CPU capacity systems. In particular, for most modern/high-end ARM SoCs with a "big.LITTLE" design where some of the ARM cores are much faster but consume more power and are complemented by lower-power cores like the ARM Cortex-A53.
