2160 kexec problem

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
[ 93.742151] kexec_core: Starting new kernel

[ 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!

Do you use LSDK 21.08?

In previous LSDK, The second kernel with kexec cannot boot up on LX2160A, this issue is fixed in LSDK 21.08.

You need to install kexec-tools 2.0.21 in Ubuntu 20.04.

Please refer to section "7.3 kdump/kexec User Manual" in LSDKUG_Rev21.08.pdf for details.
