Hello,
I was testing kexec/kdump on ls2085ardb using kexec-tools from:
https://git.linaro.org/people/takahiro.akashi/kexec-tools.git/log/?h=arm64/kdump
and kernel from:
https://git.linaro.org/people/takahiro.akashi/linux-aarch64.git/log/?h=arm64/kdump
------------------------------------------------------------------------------------
Kernel required configs:
CONFIG_KEXEC=y
CONFIG_SYSFS=y
CONFIG_DEBUG_INFO=y
CONFIG_CRASH_DUMP=y
CONFIG_PROC_VMCORE=y

Since kexec_load failed, so no meaning of trying `kexec -e`. However,
not sure whats going here.
Can you also share dmesg (kernel console log)?
Are you using spin-table cpu enable method? If yes, do you have
cpu_die() implemented?

Having worked on LS0285A-RDB before and seeing your boot logs, seems
you are using the u-boot bootloader to boot the Linux. If this is the
case, please make sure that you are using the proper PPA (EL3 firmware
responsible for managing PSCI specifications) on the board (if in
doubt contact the NXP support team).

Try removing the hugepage allocation from the command line for initial
tests - in case you are not using the networking applications (like
packet forwarding) to see if that improves the results.

Can you please share the complete logs (may be post them on pastebin)
from when the primary boots up, so that we can help you better with
the same.
Also I remember LS2085A-RDB had issues with kexec earlier as well
(http://www.spinics.net/lists/arm-kernel/msg504353.html). Please check
with NXP support if this has been resolved/root-caused at their end.

Having worked on LS0285A-RDB before and seeing your boot logs, seems
you are using the u-boot bootloader to boot the Linux. If this is the
case, please make sure that you are using the proper PPA (EL3 firmware
responsible for managing PSCI specifications) on the board (if in
doubt contact the NXP support team).

Try removing the hugepage allocation from the command line for initial
tests - in case you are not using the networking applications (like
packet forwarding) to see if that improves the results.

Hello, Pratyush
Thanks for your reply.
Could you describe how i can find out wich enable method used. One more
things, i made this tests on qemu, and it works. Logs attached.
Best Regards,
Denys

Hello, Pratyush
Thanks for your reply.
Could you describe how i can find out wich enable method used. One more
things, i made this tests on qemu, and it works. Logs attached.
Best Regards,

From your board log (log_for_com ):
PSCI: PSCI does not exist
and then
[ 60.561877] Can't kexec: CPUs are stuck in the kernel.
Above message is coming from machine_kexec_prepare() when
cpus_are_stuck_in_kernel() returns true. See, its implementation. It
will return true if number of possible cpus is > 1 and cpu_die() is not
implemented.
You can boot your first kernel with nr_cpus=1 in kernel cmdline and
then you should be able to kexec to the second kernel from there.
However, it can not be a solution. You should update your firmware with
psci implementation.
For the time being you can have spin-table work aroudn like this [1],
but please note that spin-table is discouraged upstream [2].

[ 0.000000] psci: Trusted OS migration not required

Hi Pratyush
Both solutions works. Thanks. It's temporary solution,
i will contact with NXP support team
