Hi Simon,<br>
<br>
It didn't work... I even /break/ the initialization part of SR-IOV<span class=""><br>
directly for all devices like you did to e1000 NIC, still I got this<br>
panic...<br>
<br>
How does e10k driver check the existence of SR-IOV capability actually?<br>

Hi Tom,<br>
<br>
You might want to try disabling SR-IOV support, which you can do by<br>
passing numvfs=0 to the PCI domain.<br>

Hi,<br>
<br>
I tried to work on bare-metal then, but still I came across some<br>
problems.<br>
<br>
I started Barrelfish as your README guided and then modified the<br>
GRUB<br>
entries to start e10ktest. The system started with a mess (maybe<br>
result<br>
from ANSI colors), but worked well without fish and angler.<br>
However, if<br>
I started the e10ktest by writing this line into grub:<br>
<br></span>
legacy_initrd '/barrelfish/x86_64/sbin/__<u></u>e10ktest'<br>
'/barrelfish/x86_64/sbin/__<u></u>e10ktest' 'core=1' 'queue=0'<span class=""><br>
<br>
then I got a panic:<br>
<br>
RSC not supported in SR-IOV mode!<br>
<br>
<br>
I tried to add a parameter /rsc=0 /as driver code guided,<br>
however, it<br>
didn't work at all.<br>
<br>
So, what should I do to solve this?<br>
<br>
Looking forward to your kind reply, thanks.<br>
<br>
