PCAN-PC/104-Plus Quad MSI support

[sumantra94]

Hi,
I am trying to use the PCAN-PC/104-Plus Quad (https://www.peak-system.com/PCAN-PC-104 ... .html?&L=1) with the Linux Chardev driver. Does this card support MSI interrupts?

When I run the driver with the option usemsi=1 I get a kernel error msg (pci_find_capabillity failed). So does that mean that MSI interrupts are not supported on this device?

Thanks
Sumantra

Hello,

The PC/104 device does not support MSI interrrupts.

This is only available on PCI/PCIe devices,
this is hinted at in the manual:
