Hi,
I notice the function below in kexec/arch/arm64/crashdump-arm64.c. It looks it always causes "kexec -p" to return:
"Memory for crashkernel is not reserved
Please reserve memory by passing"crashkernel=X@Y" parameter to kernel
Then try to loading kdump kernel"
int is_crashkernel_mem_reserved(void)
{
return 0;
}
Do we have plan to implement this?
Do we have workaround for arm64?
Thanks,
Zhe

which kexec-tools and which kernel are you using?
Maxim.

kexec does not yet support kdump. Patches for it are in
review. Check the kexec ML.
