Need help for arm64

[He Zhe]

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=***@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

Maxim.

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