Hi all,

I am unable to start xen in hikey successfully but getting to this prompt
message:


>* Xen 4.7.0 (c/s Mon Jun 20 11:38:15 2016 +0100 git:9a6cc4f) EFI loader*
>* Using configuration file 'xen.cfg'*
>
* Image: 0x0000000079fd0000-0x000000007acb8c00*

*> Unable to create new FDT*


*Shell*
I am following this wiki (http://wiki.xen.org/wiki/HiKey) to setup xen in
hikey. I am not sure what could cause this issue here. Appreciate all of
you input and advice here.

Thanks,
Kamenee

you have to pass hi6220-key.dtb to xen.

I have already pass hi6220-key.dtb in my xen.cfg:

options=console=dtuart dom0_mem=512M dom0_max_vcpus=4 conswitch=x
dtuart=/smb/uart@f7113000
kernel=Image console=hvc0 root=/dev/mmcblk1p4 rootwait rw
dtb=hi6220-hikey.dtb

I download the hi6220-hikey.dtb from this site:
https://android.googlesource.com/device/linaro/hikey-kernel/+/f117fa12746b59aa0a1a4d6335145e58935c422b/hi6220-hikey.dtb


Firstly, I build kernel using the command below:

make -j24 Image hi6220-hikey.dtb

I placed hikey6220-hikey.dtb in linux directory level. I also copied the
dtb into sd before booting up. Please correct me if my steps are wrong.

Re: unable start xen in hikey

The xen.cfg file seems fine to me. I suggest you try to use the dtb file 
compiled from the kernel source and update UEFI bootloader on hikey 
board to the latest version.

hope this could help.

Hi Chen,

I have tried to flash UEFI in my board with latest one but still facing the
same issue. Regarding to use dtb file from kernel source, I couldnt find
hi6220-hikey.dtb in my source kernel. i am downloading my kernel source
from here: https://github.com/96boards/linux/tree/android-hikey-linaro-4.1

I only could find hi6220-hikey.dts file in the kernel source. Therefore
download from other github but which is correct one that i need to use? In
case, I am using incorrect kernel source, pls point to me to correct one if
you aware of?

Thanks,
Kamenee

Then did you compile the device tree using "make dtbs"?

You should compile kernel first. Please follow the "Getting Started"

Hi Chen,

My previous issue was resolved when i used hi6220-hikey.dtb from this
source: https://github.com/kuscsik/device-linaro-hikey-kernel. When I
download linux kernel, there doesn't seems to contain hi6220-hikey.dtb.

But now it got stuck while loading Dom0 and below are log traces:

It just hang there after the last line above.
I have looked into those messages " d0v3: vGICD: unhandled word write
0xffffffff to ICACTIVER0"  and linux kernel already taking care to ignore
it. Therefore, I believe this is not contributing to there hang here. Any
idea on this issue?

Thanks,

Re: unable start xen in hikey

[-- Attachment #1.1: Type: text/plain, Size: 6570 bytes --]

It seems that you are using a dtb file that is not compatible with XEN
hypervisor on hikey. I strongly suggest you compile the kernel from source
in 96boards's repository. When you compile the kernel it will compile the
dtb from dts as well.

It would be good to have the wiki page [1] updated in this case.

It looks like you did not let the kernel use the console so nothing
was printed.

Make sure you have 'console=hvc0' on your Linux line.

Re: unable start xen in hikey

[Kamenee Arumugam]

[-- Attachment #1.1: Type: text/plain, Size: 3231 bytes --]

Hi Konrad,

I have already specified that in my xen.cfg :

options=console=dtuart dom0_mem=512M dom0_max_vcpus=4 conswitch=x
dtuart=/smb/uart@f7113000
kernel=Image console=hvc0 root=/dev/mmcblk1p4 rootwait rw
dtb=hi6220-hikey.dtb

Chen,

I am using linux kernel from 96 boards repo:  https://github.com/96boards/
linux.git <https://github.com/96boards/linux.git> and I compile using this
command as below:

make Image -j24 arch/arm64/boot/dts/hisilicon/hi6220-hikey.dts

There was no dtb file produced after the compilation finished. But i saw a
trace log mentioning , make: Nothing to be done for
`arch/arm64/boot/dts/hisilicon/hi6220-hikey.dts'.

 Correct me if the make command above is wrong?


Thanks,
Kamenee

Then did you compile the device tree using command "make dtbs" as I
mentioned in previous email?

Yes, I did try "make dtbs" too, but no difference and it doesn't generate
.dtb file. here is the cmd I used:

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image  dtbs

The hikey device tree will only built if you have CONFIG_ARCH_HISI 
enabled in your .config. Can you check if it is the case?

What is your .config? Have you enabled the related option for XEN?

Below a list of Xen specific options I have enabled in my kernel:

CONFIG_XEN_DOM0=y
CONFIG_XEN=y
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_BLKDEV_BACKEND=y
CONFIG_XEN_NETDEV_FRONTEND=y

CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XEN_BACKEND=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y

Hi Julien/Chen,

Thanks, it is working for me after setting CONFIG_ARCH_HISI = y in config
file. So, when i tried to boot linux thru startup.sh, it seems to hangs and
below are the traces of log:

Press ESC in 1 seconds to skip startup.nsh or any other key to continue.
Shell> FS0:
FS0:\> Image console=ttyAMA3,115200 root=/dev/mmcblk1p4 rootwait rw
efi=noruntime
EFI stub: Booting Linux Kernel...
EFI stub: Generating empty DTB
EFI stub: Exiting boot services and installing virtual address map...

Am I missing some configuration in my kernel or patches to handle virtual
address map?


Thanks,
Kamenee

I am not sure to follow. Did you ever try to boot Linux on hikey without 
Xen?

I would recommend you to get Linux working natively (i.e without Xen) 
first and then add Xen specific options in your config.
