Hi
I want test and understand xen hypervisor implementation with dom0 and domU
on omap5 board.
I followed
https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/OMAP5432_uEVM
with latest kernel(4.11.7) and xen(4.9.0) and device tree and but unable to
boot dom0.
xen stop on "Turning on pages".
please tell what version on Xen and kernel is tested on omap5 board.
Thanks
Shishir tiwari

Please drop the whole log.

IIRC it was XEN 4.5 and LK 3.18. An old and outdated stuff. The same as
OMAP5, which is discontinued maybe three years ago.
BTW, I'm really surprised you have an OMAP5 based board. Which actually
do you have?

I guess you mean "- Turning on paging -"

This is very early boot in head.S so having the full log will not really
help here...
What is more interesting is where the different modules have been loaded
in memory:
- Device Tree
- Kernel
- Xen
- Initramfs (if any)

Even though OMAP5 is not sold anymore, we should still be able to boot
Xen 4.9 on it. If it is not the case, then there is a bug in the code.

Well, actually I supposed HYP mode is not enabled. It was tricky some
time ago, not sure if it was upstreamed to u-boot.
But yep, mentioned print is after HYP mode check.
IMHO the log starting from the board power on moment will provide more
precise info about the situation.
