[questions] Dom0/DomU on ARM under Xen

[Alexey Klimov]

[-- Attachment #1: Type: text/plain, Size: 1959 bytes --]

Hello Stefano and Ian,

I'm trying to run DomU and Dom0 on ARM under Xen and have some
problems (may be question of configuration).

I'm using:
- unstable Xen mercurial repository with your "grant table" patches
and few patches from Ian Campbell (xcbuild,
xen_remap_domain_mfn_range, XENMAPSPACE_gmfn_foreign,  ARM support to
xc_dom).
- your (Stefano's) linux kernel git repository
git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git with head
3.5-rc7-arm-1. I hope all patches to Linux kernel from Stefano letters
are there.
- Fast Models with few models created as described in wiki page
http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions/FastModels
- device trees dts files (vexpress-v2p-ca15-tc1.dts and
vexpress-virt.dts) from Stefano letter on 26 July. v2p-ca15-tc1 is
attached to Xen using CONFIG_DTB_FILE and vexpress-virt.dtb is
attached to DomU zImage.

Well, kernel hangs after message (Calibrating delay loop...) when
running on models RTSM_VE/Build_Cortex-A15x4 and
RTSM_VE/Build_Cortex-A15x2. I attached logs (Dom0-A15x2 and A15x4).
Logs also shows problems with device trees (HBI and arch timer).

I can boot Dom0 on Cortex-A15x1 model (log file Dom0-A15x1 with
warning/problems about DT and HBI) and when i'm tryng to boot zImage
using xcbuild utility then it also hangs with message from Xen "Guest
data abort: Translation fault at level 3". Log file is also attached.

Could you please take a look and help?

May be i miss important config option in Linux kernel or in Xen.

Is it okay that vexpress-virt descibes V2P-AEMv7A platform and not
V2P-CA15? It looks that vexpress-v2p-ca15-tc1.dts includes
vexpress-v2m-rs1-rtsm.dtsi. Could you please also share this file if
it has specific options? And what can be reason of errors about
HBI/arch_timers when running Xen+Linux
kernel+vexpress-v2p-ca15-tc1.dts on Cortex-A15x2 model?

I can provide/send other info if you want. Thanks in advance.
Best regards,
Alexey Klimov.

That's the state of my local dev tree too. I'm not fully up to date with
all Stefano's patches so I presume we are both missing something or
other.

It is great to see interest in our project!

You also need "libxc/arm: allocate xenstore and console pages".

Unfortunately with the 4.2 tree frozen we still have few missing pieces
here and there in the Xen hypervisor and tools.
I think that Ian intended to setup a Xen tree to be used for development
with all the currently unapplied patches that are actually needed on top
of xen-unstable.

Also the xcbuild patch posted by Ian is quite limited, I am attaching
the xcbuild.c that I am currently using for my tests with PV disk and
network support.

You might also need:

"xen/events: fix unmask_evtchn for PV on HVM guests"

this is the last version that I posted:

That's correct.

I have been testing on the Cortex-A15x1 model exclusively so far, so I
am not surprised if there are any errors on the other models.
Also I know that there are still few warnings on boot, but I haven't got
around to fixing them yet.

That's should be OK.

I am attaching it. I think you might be missing an important change there.

I am not sure yet, but I'll take a look. I'll try to fix them in one of
the following version of my series.

Let me know if the missing patches and the new
vexpress-v2m-rs1-rtsm.dtsi fix the issue!

Do you normally use an SMP model? Mine is currently configured for UP,
I've been meaning to build a new one.

I found patch and applied.

Thank you very much, i renamed Ian early version of xcbuild to
xcbuild-old, added your file and fixed Makefile to have two xcbuilds.
I found your patch on June 22 and looks like i missed it, my bad.

Thanks, i checked it and used to build final dtb-file but it looks no
changes were there with file that i used.

Thank you very much for help.

Well, i still have problems after two additional patches (for Xen and
kernel). Logs are attached: add_to_physmap failed with -22 in both
xcbuild versions and bad p2m lookups and translation fault at level 2
in Xen..

As i understand from email it's better to use Cortex-A15x1 model, so i
will use this model for tests.

And i saw that Ian set up git repository for xen with latest patches
for ARM. So i'll try to use this repository.

Best regards,
Alexey Klimov.

Re: [questions] Dom0/DomU on ARM under Xen

2012/8/1 Alexey Klimov <trashsee@gmail.com>:
> And i saw that Ian set up git repository for xen with latest patches

Hello Stefano and Ian,

I used new Ian xen-unstable git repository
(git://xenbits.xen.org/people/ianc/xen-unstable.git arm-for-4.) and
Stefano linux kernel git repository (
git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git
3.5-rc7-arm-2) with additional patches:

- for linux kernel "xen/events: fix unmask_evtchn for PV on HVM guests",
- ARM hypercall ABI: 64 bit ready patch series for xen and attached
few versions of xcbuild (early version of Ian and latest version).
After applying 64-bit ready patches i observed such errors when
building xen and tools:

1)

public/version.h:61:5: error: unknown type name 'xen_ulong_t'
make[3]: *** [headers.chk] Error 1
make[3]: Leaving directory `/src/xen/xen/include'

Fixed by inserting #include "arch-arm.h" in xen/include/public/version.h

2)

Just commented snprintf(str, sizeof(str), "virt_start=0x%lx",
p_parms.virt_start); in xc.c

Then it compiled and i tried to run DomU. It looks like allocation
console_pfn and xenstore_pfn in alloc_magic_pages() in xc_dom_arm.c
creates real pain for me. With this allocation/patch xen prints "bad
p2m lookup" messages before booting DomU
(XEN) bad p2m lookup

and then everything  hangs with translation fault:

Detailed log is attached.
Ok, i moved allocation for console and xenstore pages back in
arch_setup_meminit() like in
http://lists.xen.org/archives/html/xen-devel/2012-06/msg01340.html and
then added kernel parameter keep_bootcon in DomU  device tree file and
everything booted up to "unable to open an initial console" and unable
to mount rootfs. I still didn't learn how to deal with xenstore, hvc0,
xvda and how to boot from initramfs on ARM using xcbuild but i'll try
to understand and learn this :) So may be it's good thing to
investigate or take deep look why add_to_physmap failed in xcbuild and
why there is bad p2m lookup in xen. Log is attached.

Do you have any difference between Dom0 .config and DomU .config? Did
you just attach initrd using xc_dom_ramdisk_file() call in xcbuild?
Any special configuration of xen console/xen store?

Well, i dont mean that i'm doing everything correctly but i tried to
run it fixing/commenting as much as i can. Could you please help if
you have time? I can test new changes, sent other useful info/logs.

Alexey.

I think that this is a legitimate error, I wasn't seeing it because I am
cross-compiling.

That is also another legitimate error, I'll fix it in the next version
of the patch series. Thanks for testing!

You are probably missing Ian's fix to alloc_magic_pages:

I am just using one config, attached.

Looking at the guest data abort that you are getting, I think that you
didn't update the dts and dtsi to the latest version. They are attached
to the 00/23 email "Introduce Xen support on ARM" for the linux kernel.
