Build network drivers from sources

olivierlambert

@stormi and @r1 could assist I think

stormi

I can already point at https://github.com/xcp-ng/xcp-ng-build-env though it doesn't support XCP-ng < 7.5

The kernel being more or less the same in 7.4.1 and 7.5, built drivers in that environment might work, though.

I was able to build .iso but when i try to install it on xcp-ng i get error:

xe-install-supplemental-pack tn40xx.iso

The update precheck stage failed: the server is of an incorrect version.
update: tn40xx
installed_version: product-version = %{PRODUCT_VERSION}
required_version : product-version = 7.3.0

stormi

Can you point me at the process you followed?

tom

I followed this: https://developer-docs.citrix.com/projects/xenserver-ddk/en/latest/

XCP-ng doesn't use supplemental packs (ISO) for drivers, please use your RPMs directly.

tom

Installed from RPM and everything works flawlessy. Thanks for help.

olivierlambert

Feel free to provide your RPMs, this way we could add them in a repo in the future for people who want additional drivers.

Hi Tom,

How did you build the new package based on RPM, as I want to build my own for asus wifi adapter drivers (asus PCE-AC51).

Built iso from this guide and extracted rpm from iso.

hi! I have this EN-9320TX-E network card.
Any simple way to add the driver to the xpg-ng kernel ?
I dont have any knowledge about docker..

Import the .xva and there build the module. When you get the .ko file, copy that to your host server. Then do a

install -d /lib/modules/<KERNEL_VERSION>/kernel/drivers/net
install -m 644 tn40xx.ko /lib/modules/<KERNEL_VERSION>/kernel/drivers/net
depmod <KERNEL_VERSION>

Reboot the host and then check if it was loaded with:

lsmod | grep tn40xx

Hey there,

I'm not sure this is the recommended way. @r1 can you check this?

The "correct" process is the one we use in XCP-ng, it would be great to stick (and improve) the "common" way

Also, if you add some drivers, please provide them so we could add them to the XCP-ng repo. This way, your work will be useful for everyone

r1

Yeah - the XVA approach is old and long. Easier way is to build rpm and let it install the driver. (better via yum)

I'll take a look at it to build it XCP-NG way.

Hello

I'm using xcp-ng 7.4.1

I have EN-9320TX-E network card.
I tried to build network drivers from sources for xcp-ng but its very complicated process for me.
If somebody could do it for me i would be very gratefull.
Here is link with source drivers: https://www.edimax.pl/edimax/mw/cufiles/files/download/DriverUtility/NIC/EN-9320TX-E/EN-9320TX_E_Linux_Driver.zip

Here you have https://github.com/rushikeshjadhav/EN-9320TX

It would be great if you can let us know if RPM from it works for you.

@tom So - did it work?

Hello

I have XCP 8.1 installed und need the driver EN-9320SFP+
Cannot get it working. The drivers for Linux can be found here
http://www.tehutinetworks.net/?t=drivers&L1=8&L2=12&L3=26&L4=0&L5=0&L6=0&L7=0&f=tn40xx-0.3.6.17.3.tgz

Would be great if someone could help me with that.

Thanks.
