Cell Load

[Martinez Garcia Jorge Luis (DGS-EC/ESB2)]

Hello Ralf
Thank you for your reply. I just created a cell like this:
$ jailhouse cell create ~/jailhouse/configs/bannapi-uart-demo.cell
That worked but now I want to load the uart-demo.bin file in a cell.

$ jailhouse cell load ~/jailhouse/inmates/demos/arm/uart-demo.bin doesn t seem to be working
And neither something like
$ jailhouse cell load Demo ~/jailhouse/inmates/demos/arm/uart-demo.bin

What's the correct command?
Regards,
Jorge

Hi Jorge,

[please plain text mails only]

you also need this [1] patch when using a more recent kernel. It will
reexport ioremap_page_range. Easiest thing is to just use Jan's tree for
compiling your kernel.

Hi,

look at the usage of the userspace tool:
cell load { ID | [--name] NAME } { IMAGE | { -s | --string } "STRING" }
[-a | --address ADDRESS] ...

You have to specify the cell, either by its ID or by its name. Use
jailhouse cell list to get names/IDs of cells.

The you probably want sth like
jh cell load 1 inmate.bin

[Martinez Garcia Jorge Luis (DGS-EC/ESB2)]

Hello Ralf,
Thank you. That worked. When I type jailhouse cell list, I can see that "Banana-Pi" and "bananapi-uart-demo" are both running. However, I do not see any output in the from the uart demo in the serial terminal. Is there a way to see/debug if my inmate is working properly?

Are you looking at the right uart? The demo inmates on the BananaPi are
configured to default to uart7 while the hypervisor uses uart0.

Jan

[Martinez Garcia Jorge Luis (DGS-EC/ESB2)]

Hello Jan,
Thank you for your reply. I was indeed monitoring UART7. I am able to run both demos: bananapi-gic-demo and bananapi-uart-demo on the BP but I cannot see a thing in UART7.
I am basically following https://github.com/siemens/jailhouse/blob/master/Documentation/setup-on-banana-pi-arm-board.md. and have the same set-up described there.
Please see below the terminal output (the same applies for the bananapi-uart-demo ):

I am guessing that I am doing something wrong. When I cross-compiled Jailhouse, everything seemed to be okay. However there is one message that worries me and it is the following:

make[1]: warning: Clock skew detected. Your build may be incomplete.

Can that be root of my problem?

There is another thing. In the Readme the following is stated : "Note that, since v2015.10, you need to disable CONFIG_VIDEO in the U-Boot config, or U-Boot will configure the framebuffer at the end of the physical RAM where Jailhouse is located."
I haven't done that. Can that be the problem?
Thank you for your support.

I didn't try the uart-demo in a while but I did try gic-demo with
all-latest git repos this morning on the BananaPi, and it worked for me.

This looks strange. My configs/bananapi-uart-demo.c says it's
"bananapi-uart-demo".

make clean; make ... should resolve that.

More important: hypervisor/include/jailhouse/config.h. It must contain
at least

#define CONFIG_MACH_BANANAPI 1

Are you trying next or master as branch?

You better disable this. I don't recall the exact failure mode, maybe it
was very fatal and directly visible but maybe also rather subtle.

Jan

[Martinez Garcia Jorge Luis (DGS-EC/ESB2)]

Hello Jan,
Thank you again for your support.
I am trying master as branch. My hypervisor/include/jailhouse/config.h file contains:
#define CONFIG_MACH_BANANAPI 1
#define CONFIG_ARM_GIC_V2 1

Since your set up worked, I want to try that one out instead.
Could you please tell me which Kernel version you used yesterday?
In order to patch the above-mentioned kernel, are the following patches enough : ?

Just use the latest queues/jailhouse as-is. That's what I did as well.

[Martinez Garcia Jorge Luis (DGS-EC/ESB2)]

Hello Jan,
Thank you for your reply. I took the kernel version 4.13.5 and patched it by using the following three patches:

http://git.kiszka.org/?p=linux.git;a=patch;h=cfe39555245744bed258594e794420c5d4ccdb72

http://git.kiszka.org/?p=linux.git;a=patch;h=e47a712fda9b265429e69b2f5689f885437088cb

http://git.kiszka.org/?p=linux.git;a=commitdiff;h=734b03f5c7c3d9d5486f5ae26c2efb2853b3584c

I didn't modify Jailhouse except for the hypervisor/include/jailhouse/config.h file which now contains:

#define CONFIG_MACH_BANANAPI 1
#define CONFIG_ARM_GIC_V2 1

Everything compiled and went smoothly without any sort of warnings. In the cell list I see the two cells (Banana-Pi and bananapi-gic-demo) running. However I still cannot see the output of gic-demo.bin.
Did you also take jailhouse/ci/kernel-config-banana-pi as config?

Does that UART interface work under Linux (prior to enabling Jailhouse)?

Hello Jan,
The output of $ dmesg | egrep "serial|uart" is the following

[ 1.425880] 1c28000.serial: ttyS0 at MMIO 0x1c28000 (irq = 45, base_baud = 1500000) is a U6_16550A
[ 2.826821] 1c28c00.serial: ttyS1 at MMIO 0x1c28c00 (irq = 46, base_baud = 1500000) is a U6_16550A
[ 2.860825] 1c29c00.serial: ttyS2 at MMIO 0x1c29c00 (irq = 47, base_baud = 1500000) is a U6_16550A <-- UART 7

Before enabling Jailhouse, when I type $echo "hello" > /dev/ttyS0 I get a respond. However the same is not true fro ttyS1 and ttyS2. Did you have the same issue?

I also checked my script.bin file by converting it to .fex :

[uart_para7]
uart_used = 1
uart_port = 7
uart_type = 2
uart_tx = port:PI20<3><1><default><default>
uart_rx = port:PI21<3><1><default><default>

When I see the bananapi-gic-demo.c file

/* UART 4-7 */ {
.phys_start = 0x01c29000,
.virt_start = 0x01c29000,
.size = 0x1000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |

I noticed that the starting address is 0x01c29000 and the size 0x1000, and since the address of UART7 (ttyS2) is 0x1c29c00, there shouldn t be a problem.

Regards,
Jorge

Nope, but you might be missing the required baudrate setting (stty -F
/dev/ttyS1/2 115200). But as long that this is not working, Jailhouse is
out of the picture. Maybe you have a different board variant than I and
the wiring is different.

Yes, the config is appropriate here, at least as long no one else wants
to use UART4-6 while that the demo is running.

Thank you for your reply. I have a Banana Pi M1 sold by lemaker.org. Do you have the same board?
I also read that other people have similar issues:

Hello Jan, hello Ralf,
I just wanted to let you know that I found out that UART7 on my BP was damaged. That was the last thing I was expecting. I decided to get a new one and now Jailhouse is running on top of it and I can see UART demo printing the following message:
Hello 2699(some number) from cell!
Thank you very much for your support.
