[Xen-users] Xen ARM passthrough ethernet to Domu

["蔡力刚" <cai_ligang@xxxxxxxxxxxxxxx>]

Hi,

I had bring up dom0 and domu in a arm board.

On my board, there are two ethernet deivces, I try to passthrough a ethernet to domu.

I tried to passthrough ethernet according to the following manuals:

[1] https://events.static.linuxfound.org/sites/events/files/slides/talk_5.pdf
[2] https://wiki.xen.org/images/1/17/Device_passthrough_xen.pdf

But I'm having some trouble trying.

domu.conf as below:

kernel = "/media/sdcard0/domu-Image"
memory = 1024
name = "guest1"
vcpus = 2
serial="pty"
disk = [ 'phy:/dev/mmcblk2p2,xvda,w' ]
device_tree = "/media/sdcard0/domu.dtb"                   
dtdev = [ "/ethernet@fe1b0000" ]                          
irqs = [ 258, 259 ]                                       
iomem = [ "0xfe1b0,1@0x10000" ]
extra = 'console=hvc0 root=/dev/xvda rw clk_ignore_unused'

when bring up domu, failed message below:

libxl: error: libxl_create.c:1109:libxl__domain_config_setdefault: passthrough not supported on this platform

According to [1], I delete the dtdev option, and domu boot up but ethernet failed to bring up.

According to manuals, It seems I need to add clock into domu.dtb, and change the clock reg to virtual reg ?

How can I calcuate the virtual reg?

Can anyone give me some advice how to passthrough the ethernet device to domu?

Best regards

Cailigang
