  Mapping physical peripherals through to guests without any dom0 interaction
Posted by: paresh.chaudhary - 02-02-2017, 08:20 PM - Forum: Public Support - Replies (5)

Hi,

I want to isolate dedicated hardware or memory range from a Guest os to the processor peripheral without going through DOM0 on ZYNQ MPSOC.



How it's possible in Xen hypervisor ?

  "make dist-tools" from inside a VM with controlled Internet access
Posted by: BraetonTaylor - 01-26-2017, 08:47 PM - Forum: Public Support - Replies (3)

When doing the command:

cd $PROJ_DIR/$PROJ_NAME/components/apps/xen/xen-src
make dist-tools CROSS_COMPILE=aarch64-buildroot-linux-gnu- XEN_TARGET_ARCH=arm64 CONFIG_EARLY_PRINTK=ronaldo

I get the following error:
   Cloning into 'qemu-xen-dir-remote.tmp'...
   fatal: unable to connect to xenbits.xen.org:
   xenbits.xen.org: Name or service not known
when it is running "/disk2/XZD/XenDOM0/components/apps/xen/xen-src/tools/../scripts/git-checkout.sh git://xenbits.xen.org/qemu-xen.git qemu-xen-4.7.0-rc4 qemu-xen-dir"



To make the system use http instead of git, I can update file "components/apps/xen/xen-src/Config.mk" and add line "export GIT_HTTP=y" just before line with "ifeq ($(GIT_HTTP),y)".

Then I get this:
   Cloning into 'qemu-xen-dir-remote.tmp'...
   fatal: unable to access 'http://xenbits.xen.org/git-http/qemu-xen.git/': Could not resolve host: xenbits.xen.org
when it is running "/disk2/XZD/XenDOM0/components/apps/xen/xen-src/tools/../scripts/git-checkout.sh http://xenbits.xen.org/git-http/qemu-xen.git/ qemu-xen-4.7.0-rc4 qemu-xen-dir"

Note the use of http: and git-http now.

To fix this error, I can define these:
  export http_proxy=<Company Proxy Server with my User Name and Password>
  export https_proxy=<Company Proxy Server with my User Name and Password>

Then I get this, this is how it should look:
  Cloning into 'qemu-xen-dir-remote.tmp'...
  remote: Counting objects: 302654, done.
  remote: Compressing objects: 100% (72963/72963), done.
  remote: Total 302654 (delta 245259), reused 284315 (delta 228934)
  Receiving objects: 100% (302654/302654), 96.06 MiB | 2.33 MiB/s, done.
  Resolving deltas: 100% (245259/245259), done.
  Checking connectivity... done.

However, I cannot use this as final solution, as putting my user name and password into a script or even environment variables is not allowed.  Any suggestions on how to fix this?  Ideally, I would like to download all the components that I need ahead of time, put them into a Zip files and just unzip them instead of downloading them.

  Xilinx PetaLinux 2016.3 and XZD
Posted by: BraetonTaylor - 12-21-2016, 03:53 PM - Forum: Knowledge Base - Replies (1)

Are there any updates to XZD required to use it with Xilinx PetaLinux 2016.3?  The latest version I see of XZD is 20160930, which is before PetaLinux 2016.3.

  ARINC 653 Scheduling Utility

To make using the ARINC 653 scheduler with XZD easier, we have posted the source code to a Xen ARINC653 command line scheduling utility to github.  Instructions for building it with the XZD distribution and for using it can be found in the README.

  How do you start Guests automatically?
Posted by: BraetonTaylor - 11-30-2016, 01:43 PM - Forum: Public Support - Replies (5)

How do you start Guests automatically?  I tried this on the target, but it did not work. 
 
    cd /etc/xen/auto
    ln -s /root/Dom1_Linux.cfg .
 
I tried adding these to the .cfg file as well:
 
    on_xend_stop = ‘shutdown’
    on_xend_start = ‘start’

  Xen distribution for Zynq-7000
Posted by: lar_fer - 11-19-2016, 09:24 AM - Forum: Public Support - Replies (2)

Hello,

I was wandering if there is a Xen Distribution for the Zynq-7000 device family.

If anyone one knows about a project for Zynq-7000, please let me know.

regards,

  Building XZD without an Internet connection
Posted by: BraetonTaylor - 11-02-2016, 07:42 PM - Forum: Public Support - Replies (7)

The XZD BSP petalinux-build (Section 5.2  step 5 of the Xen Zynq Distribution User’s Manual 
(Xilinx-XenZynq-DOC-0001 v0.7 July 1, 2016)) produces an error if you do not have an Internet connection.

I tracked this down to the petalinux-config, it has u-boot config set as "remote", with remote set to "https://github.com/dornerworks/u-boot-xlnx.git".
This will not work unless connected to the network.  What is the alternative?  Can I downloaded it separately and put it some place and point to that?
If so, where do I put it and how do I point to it?  It does build if I change this to "u-boot-plnx", but I am guessing that I will be missing some 
capability in the U-BOOT application.  Do all I lose is the "run xen" command?

See log of build attempt:

  FIT Image file handling
Posted by: john_dino_dinatale - 11-01-2016, 01:18 PM - Forum: Public Support - Replies (5)

Hi,

I went through this document:
http://events.linuxfoundation.org/sites/events/files/slides/U-Boot%20FIT%20for%20Xen.pdf
And I have a uImage.its, which was able to create a uImage.itb. When I use the “bootm” command, I get the following:
U-Boot-E6Kn>bootm 0x6000000:xen@1
Wrong Image Format for bootm command
ERROR: can't get kernel image!
 
I’m using “xen.ub”, for the node image. Is this the correct file?

I tried to attach my ".its" file, but couldn't, because of a file format problem. I'll attach it when I figure out how to? Huh

 
Thanks,
Dino
