Hi, I wanted to try out the ipxe networking (I'm not entirely sure if my NIC is even supported) and I ran the run/noux_net_openssh_interactive configuration on my device and got an error.
I got a lot of these messages: [init -> nic_drv] --- get MAC address 00:22:68:14:68:b2 [ 0] DMAR:0xffffffff810210e8 FRR:0 FR:0x2 BDF:0:19:0 FI:0x02c00000 [ 1] Killed EC:0xffffffff83387280 SC:0x0 V:0xe CS:0x8 EIP:0xffffffff81008918 CR2:0x7400061a8 ERR:0x0 (#PF (kernel)) [ 0] Killed EC:0xffffffff83387040 SC:0x0 V:0xe CS:0x8 EIP:0xffffffff81008918 CR2:0x7400061a8 ERR:0x0 (#PF (kernel)) [ 1] Killed EC:0xffffffff83387280 SC:0x0 V:0xe CS:0x8 EIP:0xffffffff81008918 CR2:0x7400061a8 ERR:0x0 (#PF (kernel))

The NIC itself is: Ethernet controller [0200]: Intel Corporation 82567LM Gigabit Network Connection [8086:10f5] (rev 03)
Is this due to hardware incompatibility or something else?

A DMA operation to the physical address 0x2c00000 is stopped by a IOMMU and the kernel reports that. On Genode/Nova this typically means that one forgot to load/use the device_pd [0]. Looking at the run script there indeed the acpi driver and the device_pd application is missing.
The attached patch adds the missing pieces to the run script. Probably there are some more run scripts out there missing the acpi driver and device_pd for Genode/Nova.

This looks not good. I can't reproduce it here. Do you use the 14.11 Genode release with the nova kernel revision 2b4f2803218cf92e2982b47a370d60b18bb78a15 (r7) in repos/base-nova/ports/nova.port ?
Cheers,
Alex.

I am using 14.11 with its version of nova REV(nova) := 2b4f2803218cf92e2982b47a370d60b18bb78a15
applying your patch fixes the boot time problems. Now it boots to bash. When I tried to run an ssh command "ssh -p 1234 1.2.3.4 uptime" though, I got a fault:

The noux-pkg/openssh/install/bin/ssh binary doesnt have any segments in the 0x10f36b1 range.

Our new ldso does not provides the '__progname' symbol that is used by OpenSSH implicitly. There is a fix [1] but it is not yet on staging because I want to update OpenSSH anyway. For now you can cherry-pick the commit and rebuild the noux-pkg.
Cheers Josef
