| H A D | cpupri.h | diff a1bd02e1f28b1939cac8c64072a0e578c3cbc345 Mon Mar 02 07:27:18 CST 2020 Qais Yousef <qais.yousef@arm.com> sched/rt: Optimize cpupri_find() on non-heterogenous systems
By introducing a new cpupri_find_fitness() function that takes the
fitness_fn as an argument and only called when asym_system static key is
enabled.
cpupri_find() is now a wrapper function that calls cpupri_find_fitness()
passing NULL as a fitness_fn, hence disabling the logic that handles
fitness by default.
