Hi Daniel,
I checked AFTR on v3.14 (
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/?id=refs/tags/v3.14)
on exynos5250 based chromebook (exynos5250-snow.dtb)
I am able to hotplug CPU1 (echo 0 >
/sys/devices/system/cpu/cpu1/online).
I can see, it enters exynos4_enter_core0_aftr() when I hotplug CPU1.
Hi,
thanks a lot for your help.
I reproduced it on my arndale board with linux-samsung/for-next and on
v3.14.
Used the exynos_defconfig, enabled cpuidle and used
exynos5250-arndale.dtb.
You should compare your bootloader versions as this is one of the
aspects that can break AFTR support as it relies on kind of ABI between
bootloader and kernel.
U-Boot 2013.01.-rc1 (Jul 10 2013 - 15:16:09) for ARNDALE5250
