Re: exynos5422-odroid-xu3: MCPM: only 6 of 8 CPUs coming online

by Abhilash Kesavan

Hi Kevin, I had noticed a similar issue where only 6 cores would come up during development on 5420. This was because there was a check in our u-boot secondary boot-up path which would put a core into WFI if a flag was not present and hence fail to boot. I wonder if it is the same situation in your case too. Is the u-boot for odroid-xu3 publically available or can you check if there is any such code present in your secondary bring-up path. Regards, Abhilash ------- Original Message ------- Sender : Kevin Hilman<khilman(a)linaro.org> Date : Oct 09, 2014 00:28 (GMT+05:30) Title : exynos5422-odroid-xu3: MCPM: only 6 of 8 CPUs coming online Hi Chander, Abhilash, I'm using the exynos5422 odroid-xu3 and only 6 of 8 cores are coming online when using MCPM[1]. All the A15s are booting but only 2 of the A7s, one of which is the primary CPU. After booting, if I try to manually bring one of the CPUs online via /sys/devices/.../cpuX/online, I hit the BUG() in mcpm-exynos.c:exynos_power_up(). Any ideas why 2 of the A7s aren't booting up?
