Hi Pratyush,
I am using yocto(2.3 version) to build makedumpfile, which fetches v1.6.1
makedumpfile and also applys some patches including arm64 specific
patches.
What are these ARM64 specific patches? I believe, you do not need any topup
in makedumpfile for ARM64 if you use v1.6.1.
Sorry, I got confused with yocto kexec recipe.
There are NO arm64 specific patches in yocto for makedumpfile.
We have VA_BITS set as 48 bits... I will get other information and post
on the
list.
OK.
Kernel config:
ARM64_VA_BITS_48 [=y]
ARM64_PAGE_SHIFT [=12]
RANDOMIZE_BASE [=n]
ARM64_4K_PAGES [=y]
These are the only variable configs on which arm64 makedumpfile depends. I
tested with above configuration and things were working fine.
I used 4.11 based kernel and crash-7.1.9.
BTW, which version of crash utility do you use. If you are not at latest can
you please try with latest.

CCed Dave if he has some input.
