Oops, I forgot to CC Viresh and Vincent on this, so resending... --- We can't rely on Kconfig options to set the fast and slow CPU lists for HMP scheduling if we want a single kernel binary to support multiple devices with different CPU topology. E.g. ARM's TC2, Fast Models, or even non big.LITTLE

[PATCH] sched: Use device-tree to provide fast/slow CPU list for HMP

2012-07-14 Thread Jon Medhurst (Tixy)
We can't rely on Kconfig options to set the fast and slow CPU lists for HMP scheduling if we want a single kernel binary to support multiple devices with different CPU topology. E.g. ARM's TC2, Fast Models, or even non big.LITTLE devices. This patch adds the function arch_get_fast_and_slow_cpus()
