How to enable kernel crash dump on ECI 3.0(Debian Distribution)

Hi all,

 

I'm using Intel ECI 3.0(Debian Distribution, LTS PREEMPT_RT kernel 5.10.115-rt67-intel-ese-standard-lts-rt+, Installed by using ECI deb packages),
and I would like to enable kernel crash dump to dump whatever is in RAM (memory) to disk when the execution of the Linux kernel is halted or crashed.

 

I checked the kernel config parameters and It seem that the LTS PREEMPT_RT kernel doesn't suport kernel crash dump:
          # CONFIG_KEXEC is not set
          # CONFIG_KEXEC_FILE is not set
          # CONFIG_CRASH_DUMP is not set


So, I was wondering if you could give me some advice on how to active kernel crash dump on Intel ECI 3.0 ?
And in case I have to change the kernel config parameters for support kernel crash dump, please advise me how to change these parameters.

 

Best regards

BUI

Hi,

 

Please refer 

https://eci.intel.com/docs/3.0.1/development/eci_build_engine.html

Step 4: Start a bitbake Environment

 

Please try the following

./setup.sh

KAS_CONTAINER_IMAGE=jammy-kas-isar:3.0.2 ./kas-container --git-credential-store ${HOME}/.git-credentials shell targets/kas/eci-packages-bullseye.yml

#add your kernel config

vi /work/targets/layers/meta-tgr/meta-eci-isar/recipes-kernel/linux/files/amd64_5.10_intel_defconfig

bitbake linux-intel-rt -c cleansstate && bitbake linux-intel-rt
exit

 

#obtain the deb package and install

build/eci-packages-bullseye/tmp/work/eci-bullseye-amd64/linux-intel-xenomai/5.10.140-4/linux-headers-intel-xenomai_5.10.140-bullseye-4_amd64.deb
build/eci-packages-bullseye/tmp/work/eci-bullseye-amd64/linux-intel-xenomai/5.10.140-4/linux-image-intel-xenomai_5.10.140-bullseye-4_amd64.deb
build/eci-packages-bullseye/tmp/work/eci-bullseye-amd64/linux-intel-xenomai/5.10.140-4/linux-intel-xenomai_5.10.140-bullseye-4_amd64.deb

Best Regards,

Lay

Hi BUI,


I've been looking through the ECI documentation and I'm not seeing anything related to enabling kdump. Let me reach out to the development team for additional assistance. I will let you know what I find out.


Regards,

Jesus
