.B auto_reset_crashkernel <yes|no>
.RS
determine whether to reset kernel crashkernel parameter to the default value
or not when kexec-tools is updated or a new kernel is installed. The default
crashkernel values are different for different architectures and also take the
following factors into consideration,
- AMD Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV)
- Mellanox 5th generation network driver
- aarch64 64k kernel
- Firmware-assisted dump (FADump)
Since the kernel crasherkernel parameter will be only reset when kexec-tools is
updated or a new kernel is installed, you need to call "kdumpctl
reset-crashkernel [--kernel=path_to_kernel]" if you want to use the default
value set after having enabled features like SME/SEV for a specific kernel. And
you should also reboot the system for the new crashkernel value to take effect.
Also see kdumpctl(8).
