  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,

Alex

  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 (7)

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

  Question about isolation of DMA masters between domains
Posted by: jwolff - 09-20-2016, 12:11 AM - Forum: Public Support - Replies (4)

Hello, we have been using the DornerWorks MPSoC Xen distribution for a few weeks now and have had a very good experience so far.  I do have one question about isolation of DMA masters between domains as follows.  We have been able to configure a pass-through serial port using an analogous procedure to what you describe in the "Xen Zynq Distribution (XZD) UART Pass Through How To Guide":
http://xzdforums.dornerworks.com/showthread.php?tid=577
 
What I haven't seen any reference to in your documentation is how to restrict the physical memory to which a DMA-capable peripheral has access.  I would expect Xen to use the SMMU to prohibit a DMA-capable peripheral from being able to access any memory except what is assigned to the domU VM that is controlling the peripheral.  Or perhaps a better system would configure the SMMU whenever a driver allocates a DMA buffer, such that the peripheral can only access specific buffers that are allocated by the guest OS.  However, I haven't been able to find any documentation online describing how to do this.  Is this possible, and if so how?
 
Thanks very much in advance for your help with this question!

  uboot getting hang after "tftpb 0x80000 Image"
Posted by: sunitksharma - 09-07-2016, 04:55 PM - Forum: Public Support - Replies (5)

Hello,

I am using Xen Zynq Distribution, following user Manual (Xilinx-XenZynq-DOC-0001 v0.7 July 1, 2016). I am seeing a random issue of uboot getting stuck. Previously I was running uboot script "xen" as specified in 4.2.1.6 as "run xen". Later i started running each command from the xen script on uboot console. I found that after image is loaded, the uboot console hangs.

Following are the logs. I am loading u-boot.elf from JTAG. Is there an issue/bug in u-boot.elf. Please advice.

Thanks,
Sunit
