ARM soc's not so powerfull to ignore compile optimizations , but binary distributions like ubuntu designed to work on all hardware. So if you use ubuntu - you lose some power from you current device . In Gentoo you can set compile flags for whole system : A10 - CFLAGS="-mcpu=cortex-a8 -mfloat-abi=hard -mfpu=neon -mthumb" A20 - CFLAGS="-mcpu=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4 -mthumb" -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
