The one questino I have is, do we want default y?I also agree that default y is preferable.I'll change at least the x86 one to: default y depends on SMPHuh, so the arm64 SCHED_{SMT,MC} configs are defaultless (I added SCHED_SMT to arm64's defconfig not so long ago), but x86 has them default y, which I'm thinking is a tad better, and would be nice to harmonize. Unfortunately different architectures have their own dependency requirements - arm has ARM_CPU_TOPOLOGY, parisc has PARISC_CPU_TOPOLOGY... Would you hate making SCHED_* a "generic" config, with a common default and help text, and punt the arch specific stuff to an ARCH_SUPPORTS_* knob? Something like: arch/arm/Kconfig: select ARCH_SUPPORTS_SCHED_MC if ARM_CPU_TOPOLOGY init/Kconfig: config SCHED_MC def_bool y depends on ARCH_SUPPORTS_SCHED_MC && SMP
... Which is essentially what Barry suggested somewhere else in the thread (I TL; DR'd). _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
