I never tried to boot Xen on Jetson-TK1 myself.

Could you provide the command line you use to compile Xen (with 
earlyprintk enabled) and the U-boot runes?

I am running a ubuntu trusty schroot and I am using the Ubuntu/Linaro
arm-linux-gnueabihf-gcc 4.7.3
as the cross compiler to compile everything. The tree which I pointed
towards (in my previous mail)
contains the earlyprintk configurations for Jetson-TK1, so I am using this
command to compile Xen with earlyprintk -

make dist-xen debug=y CONFIG_EARLY_PRINTK=jetson XEN_TARGET_ARCH=arm32

I want to update my current stage with Xen, after using this toolchain I am
able to get Xen to print output
on the Jetson-TK1's serial console and Xen is able to boot correctly with
all 4 cores in HYP mode.

But the problem is when Xen tries to boot the dom0 kernel and transfer
control, I receive no output on the serial port.
I am using Linux 4.1.0 as the dom0 kernel and the kernel is compiled with
Xen specific options enabled.
Also the same linux kernel is able to boot on the board without Xen.

I am passing the dom0 kernel argument to Xen in the /chosen node in the
device tree using these commands  -

fdt mknod /chosen module
fdt set /chosen/module compatible "xen,linux-zimage" "xen,multiboot-module"
fdt set /chosen/module reg <0x0 $kernel_addr_r 0x0 0x$filesize>
fdt set /chosen/module bootargs "$bootargs"

I am loading Xen at top of the ram and linux and device tree at their
default locations (near starting of ram).

This is the Xen BootLog which I receive through the earlyprintk serial port

After this last line the system just hangs with no output on the serial

Is this some problem with the way I'm passing the dom0 to Xen or the
bootargs to the kernel?
Or could it be some problem in my kernel configuration used at the time of
compiling linux?
If you want I can post my kernel .config also.

Thanks in advance.

I haven't run Xen on ARM yet. But just a random thought:
Is it possible that you need to provide the console=hvc0 for the boot
cmdline of dom0?

dom0 needs share the serial port with Xen.

But is dom0 booted up?
If you have network, can you connect to it?
If dom0 did boot up, then at least we know it's some configuration issue.
Again, I haven't tried on ARM yet, but I'd love to... :-)

I have added the serial port in the bootargs passed to the kernel. The
bootargs
passed to the dom0 when executing with Xen are the same bootargs which I
pass
when I run the kernel standalone without Xen and at that time I am able to
see the
kernel bootlog and a tty console on the serial port.

Yes, I have network on the board and I have configured the board to get
fixed ip from my local
network but even after waiting sometime I am not able to see any network
response from the board.
So I guessed maybe the dom0 is not booting correctly.

Ahha, that's the problem!

when Linux runs in native env., it will use serial port, say com1, you
can use console=com1 or console ttyS0 for the boot cmd.
However, when you run linux in dom0, linux won't see the hardware
ttyS0 directly. It must go through Xen to see it. So the linux's
cmdline in dom0 must be console=hvc0, instead of ttyS0 or com1.

Can you try this and see if it fix the problem?

Hmm, probably... If Linux in dom0 have network on bare metal, it
should have network in dom0 after you boot Xen 4.5+.
Probably you can try the above suggestion and see if you can see some
interesting log?

Thanks for pointing this out, I changed the console name when booting linux
as dom0.

After changing the console name to hvc0 the only thing which I noticed
differently is
that after the last line where Xen frees some init memory, I am able to see
the linux
kernel decompression message -

"(XEN) DOM0: Uncompressing Linux... done, booting the kernel.

But after that the system just hangs the same way without any response on
the network either.

Thanks,
Dushyant

Has Linux been compiled with the appropiate CONFIG_ parameters? That is you
have Xen enabled on it?

The list of options looks good to me. I guess Linux is crashing before setting
up the console. Can you apply the below to Linux and post the log here?

I applied your patch to Linux but still there is no output from the kernel.

But I have found location of the problem, I have a debugger attached
to the Jetson board
and using that I was able to find out that Linux is failing while
initializing the Tegra timer.

The call stack at the time of failing is  -

-   prefetchw (inline)
    arch_spin_lock (inline)
    do_raw_spin_lock_flags (inline)
    __raw_spin_lock_irqssave (inline)
    raw_spin_lock_irq_save (lock = 0xC0B746F0)
-   of_get_parent (node = 0xA00001D3)
-   of_get_address (dev = 0xDBBABC30, index = 0, size = 0xC0A83F30)
-   of_address_to_resource(dev = 0xDBBABC30, index = 0, r = 0xC0A83F50)
-   of_iomap (np = 0xDBBABC30, index = 0)
-   tegra20_init_timer (np = 0xDBBABC30)
-   clocksource_of_init()
-   start_kernel()

After this Linux jumps to floating point exception handler and then to
undefined instruction and fails.

Thanks,
Dushyant

I don't know why Linux is receiving a floating point exception. However, 
DOM0 must not use the tegra timer as it doesn't support virtualization.

You need to ensure that DOM0 will use the arch timer instead. Xen 
provides some facilities to blacklist a device tree node (see blacklist 
dev in arm/platforms/tegra.c).

I have blacklisted the tegra20_timer and now dom0 is able to pass that
step but now the dom0 kernel gets stuck in an infinite loop in the
function calibrate_delay_converge.

This is the call stack -
 -  calibrate_delay_converge
 -  calibrate_delay
 -  start_kernel

Right now I'm not sure about the exact point where it is going into
the infinite loop.

I was not receiving the dom0 logs because of a mistake in my dom0
bootargs. In the bootargs the option
for earlyprintk was not marked as Xen. Now that I've enabled it I'm
able to see some bootlog from dom0 linux.

At least now I'm able to figure out the reason of Linux running into
infinite loop.

It seems like Linux is not receiving any interrupts from the arch
timer and when it tries
to calibrate the timer delay then there's a loop where linux waits to
receive ticks to calculate
loops_per_jiffies and that's the point where dom0 is running into the
infinite loop.
(exact point is http://osxr.org:8080/linux/source/init/calibrate.c#0196)

This is the dom0 bootlog which I received after correcting the
earlyprintk argument -

Can anyone explain why Linux is not able to get any interrupts from
the arch timer?
Is this some problem with Xen's interrupt mappings or some issue with
the dom0 kernel?

Thanks,

Can you provide the full log? So we can see if there is anything which 
could give us a hint about your problem.

 From the log: "arch_timer: No interrupt available, giving up". So the 
kernel is not able to get the interrupt from device tree.
Which device-tree are you using for the board?

I am using the device tree which is built with the Linux kernel
version 4.1.0 (tegra124-jetson-tk1.dtb),
I have also attached the device tree source with this mail, If you
want to have a look.

It looks like to me that Xen is not recreating the device-tree 
correctly. I would look into the kernel to find what is expected.

This looks like a possible bug (or some missing feature) in Xen's
device tree creation which could
take some time to handle, so if I could be of any more help to you
with this issue please let me know.

[I've cc'ed Ian Campbell in this mail (Sorry for cc'ing you explicitly)]

Ian,

Actually, I want to run Xen on the Tegra Jetson board for some project
of mine but currently Linux-4.1 is
failing as dom0 because its not able to receive interrupts from the arch_timer.
This link contains the dom0 failure boot log -
http://lists.xenproject.org/archives/html/xen-devel/2016-03/msg03715.html

In your patch for *Hacky* support for Jetsok-TK1 you said that you
were able to run guests on
Jetson-tk1 board with Xen. Can I know which kernel version you used as
dom0 (and possibly domU guests)?

Thanks and Regards,
Dushyant Behl

There was a conversation on #xen-arm few days ago about this problem.
Xen doesn't correctly recreate the GIC node which result in a loop 
between the interrupt controller. Can you try the below patch?

I'm afraid I don't remember. It would probably either have been some
current-ish upstream kernel from the time, or possibly a Debian kernel
from around the time. So maybe something 3.16-ish?

@Ian Thanks for the Reply.

@Julien, Thanks a lot, your patch for GIC dtb node worked and the
linux kernel is now able to enable the arch timer.
(Although I needed to modify the code manually as the tree I'm using
is older Xen-4.6, and maybe the patch was against the latest version
of xen).

The kernel is able to initialize itself but it fails while initializing some
nvidia devices in the boot process. I've posted the log here,
Could this also be an issue with the device tree or this is something
related to the kernel?

Thanks to Dyshyant's help, I see the similar log as Dushyant attached
in his email.

No, I was not able to boot the dom0 kernel successfully hence I was
not able to login into the dom0 linux.

It seems this link is invalid now...
Has this patch been upstreamed?

Hi Dushyant,
Could you help repost this patch in this email if it's not that large?
(Since we used the same repo, which is IanC's, it may be even better
if you could kindly share the patch based on the tegra-tk1-jetson-v1
branch of Ian's repo.?)


Hi Julien,
Do you have some suggestions on how we can debug and fix the issue
related to the device tree?

I saw that there may still be some issues with the NVIDIA devices as
Dushyant described after he applied the patch.
Right now, I have the exact same board as Dushyant has. I think I may
encounter the exact same issue as he did. So I'm wondering if there is
some documentation/tutorial/notes that we can learn about how to debug
the issues.

Thank you both very much for your help and time!

Best Regards,

Meng

Thank you so much for your help! I applied the patch and the kernel
can have further progress in booting.

I'm replying to your last email about the issue I'm facing to, which
seems not same with what you saw.

I guess you blocked the "tegra20-timer" (which uses "-" instead of
"_") right as shown in the following patch? Am I right?

That was a typo in the email but I had blocked the correct timer, without
blacklisting the tegra timer the linux only boots to a few steps and
fails, in my next
bootlog linux booted a lot further and then failed due to some other reason.

I just got the Jetson TK1 board and I'm trying to run Xen on it.

May I know which u-boot repo and which branch you used to enable the
non-secure mode? If you could also share your u-boot config file, that
will be awesome!

The u-boot from NVIDEA didn't turn on the HYP mode. I tried the
git://git.denx.de/u-boot.git, tag v2016.03, but the board won't boot
after I flashed the uboot. No message at all... :-(
If I use NVIDEA's uboot, I can boot into the linux kernel without problem.

Thank you very much for your help and time!

Best Regards,

Meng

I'm using the u-boot from mainline git://git.denx.de/u-boot.git on my
Jetson board, I'm using the tegra-uboot-flasher-scripts from Nvidia
(https://github.com/NVIDIA/tegra-uboot-flasher-scripts)
to flash u-boot and they use the denx mainline branch with default
Jetson-TK1 configuration.

The default configuration of u-boot doesn't enables HYP mode when you boot
the kernel. You can change that in the configuration by disabling

CONFIG_ARMV7_BOOT_SEC_DEFAULT in the config file.

But you can also achieve the same thing by setting the environment
variable in u-boot

"bootm_boot_mode=nonsec"

now booting the linux kernel through bootm command will boot it in HYP mode.
I'm also using the bootm_boot_mode variable set to nonsec without
changing the default
configuration of u-boot.

I had some problems booting the L4T kernel in HYP mode on Jetson, so I was using
the linux kernel from Jan Kiszka's development tree -
http://git.kiszka.org/linux.git/,  branch queues/assorted
which has some of the PSCI patches required to boot linux. Although If
you do get the
mainline linux or l4t kernel to boot in nonsec mode or on Xen, please
do let me know.

Thanks,
Dushyant
