Sure , I can share with you /proc/iomem , I opened it using vi and copied the
contents into a .txt file (my Tera term cannot emulate the USB for now) , I
have attached the file with this email.

Subject: RE: DMAR region size cannot be identified on Intel architecture
Hi,
I already found out the error which was that I did not enable intel_iommu on
the target linux which is why I could not proceed, hence I edited
/boot/EFI/BOOT/grub.cnf and everything is ok(sorry I did not update earlier) .
However I have an additional problem, I see some of the steps that
GRUB_CMDLINE_LINUX="memmap=XXX" needs to be configured in /etc/default/grub
however my target machine does not have that so can I just append
memmap="0x4200000\\\$0x3b000000" in /boot/EFI/BOOT/grub.cnf and then update the
grub and finally reboot?
Regards,
Swaraj Dube.

If you are on the same machine, you can go for config create directly (just
leave out "-r path/to/untarred/data").

For collecting informations about the IOMMU, we currently need Linux using it,
therefore intel_iommu=on (or, statically, CONFIG_INTEL_IOMMU_DEFAULT_ON). Could
you share your /proc/iomem and dmesg output in that case?
(Technically, we could remove that dependency as well -
jailhouse-hardware-check now demonstrated how we can obtain information also
from registers, in this case the region size. Cleanup for the todo
list...)
