PCAN-miniPCIe FD - IMX6 - kernel 4.9.124

[M.Maidhof]

Hi,

please see info in the linux driver manual on page 11. This parameter defines how the interrupt is used on that PCAN-miniPCIe FD card (MSI or INTA).

Looks like your IMX6 board has some problems with INTA on PCIe.

Hi,

This parameter requests the driver to run in the (so-called) MSI mode rather than in INTA (legacy) mode. In MSI, interrupts are no more wired interrupts but are messages sent on the bus. Depending on the hardware on the mobo, MSI mode is the preferred mode to run with interrupts and PCIe devices. Modern drivers should first try to run in MSI mode but, for historical reasons, the pcan driver default behavior is to run in INTA mode.

This parameter, as well as all other parameters, is described in the documentation provided in the driver package.

Regards,
