Build Socketcan on Ubuntu 22.04.2 LTS / 5.19.0-35-generic

Ixxat Support PCI Cards
#1

Dear Support,

I am getting an error when building the SocketCAN_2_0_378_Modified_PeWu_2022-02-11/ix_active_can_2.0.377-MOD for a IB2x card on mentioned Ubuntu version. Unfortunately we can’t use older versions otherwise our DAQ cards will not work anymore, so I am a bit stuck. I am getting errors with the

pci_alloc_consistent(pdev, intf->dmalen, &intf->dmaadd);
pci_free_consistent(pdev, intf->dmalen, intf->dmavadd, intf->dmaadd);

functions, which seems to have been replaced with dma_ function in the newer kernels. Has there been any work done on this? The LTS versions of Ubuntu that you state on your website are going to be out of support within this year so I was hoping there was something new that is not on the website yet?

Thanks
Tim

Hi Kyle,

However failes with the below error on the latest mainline kernel with message below. Any thoughts?

Thanks
