Hi
I am working on 2160 processor to use kexec to jump into a new kenel, but after "kexec -e", the board haltled, like this:
# /usr/kexec -e

[ 94.417654] Bye!
Then the console has no output, After reading kexec code, I got some question:
1. Does 2160 processor support VHE? I got message from 2160 datasheet that the core support all ARMv8 feature, but the value of register id_aa64mmfr1_el1 is 0.
2. Should I configure CONFIG_KVM to reconfigure the interrupt vector table? The function el2_setup has configure the el1_sync.
Thanks!
