Hi,
for the completeness sake: it's about ivshmem-net. The PCI device shows
up in the root cell and can be discovered via lspci, but the driver
fails while probing with
[17061.414176] ivshmem-net 0000:00:01.0: enabling device (0000 -> 0002)
[17061.420598] ivshmem-net 0000:00:01.0: invalid IVPosition -1
The register read-out failed. Maybe a mismatch between driver and Jailhouse
version: Which revisions are you using on both sides?
Jan
[17061.426193] ivshmem-net: probe of 0000:00:01.0 failed with error -22
AFAICT, the device is correctly set up in the system configuration.
Thanks
Ralf

Hello,
I want to set up a shared PCI device in the root cell but got stuck in
the process.
I did the following:
I reserved a memory region for IVSHMEM and referenced this region in the
pci_devices.
When checking lspci the device shows up but looking at the dmesg the
probing of the driver failed.
I attached the configuration used, lspci of the device and the dmesg.
I hope you can help me what's going wrong here.
Thanks,
Mario
