[Xenomai] Failing to recognize/use PEAK PCAN-miniPCIe card

[Xenomai] Failing to recognize/use PEAK PCAN-miniPCIe card

[Daniel M. Drucker, Ph.D.]

Hello all,

We have a PC/104 computer with a PEAK PC/104-PLUS card which we are
successfully using to talk CAN from within Xenomai. For various reasons, we
want to switch to using a mini-ITX board.

We're trying to use the PEAK PCAN-miniPCIe card on the mini-ITX board, but
we are having no luck - the card doesn't seem to get seen by Xenomai.

We're not sure if this is an IRQ problem or something else. On the PC104
system, we had an IRQ conflict which we were able to solve by changing a
jumper - the new card has no jumpers to change, and our motherboard's BIOS
does not have any settings that allow changing of daughterboard IRQs.

Both systems are running the same OS install with the same kernel. The
'latency' command in the Xenomai testsuite runs correctly on both systems.

I have put together a comparison of command outputs on the old (working)
and new (non-working) systems:  http://goo.gl/GBy8h

Any insight into what's wrong in our new system and how to get it working
would be greatly appreciated!

Thanks,
Daniel

What does lspci say? Is your card listed? If yes, are the IDs of this
card in the list of IDs which the xenomai driver supports?

The PEAK-related part from lspci is in my original message. (See the link I
included:  http://goo.gl/GBy8h )

Is there other information from lspci that would be relevant?

Thanks,
Daniel

The numerical IDs, to compare them with the list of numerical IDs
supported by the drivr.

Ok, I updated the spreadsheet using lspci -nn -vvv. I think the [0280] is
what you're looking for? Where do I find the list you're referring to?

I am not looking for anything. The list is in the driver code.

Re: [Xenomai] Failing to recognize/use PEAK PCAN-miniPCIe card

[Daniel M. Drucker, Ph.D.]

Aha. So since ours is identifying as 001C:0008, it's not picking it up.
Thank you, this is very helpful!

Daniel

Re: [Xenomai] Failing to recognize/use PEAK PCAN-miniPCIe card

[Daniel M. Drucker, Ph.D.]

Success!

All we had to do was add:

#define PEAK_MPCI_DEVICE_ID  0x0008  // Device ID for newer PCIe cards
(IPEH-003027)

and add that to pci_device_id peak_pci_tbl[].

Note that that ID is included in the user-mode driver (
linux-3.5.7/drivers/net/can/sja1000/peak_pci.c ).

Thank you!

Daniel

If the driver is in the kernel sources, chances are that it is not a
user-mode driver at all...

The latest Linux driver (7.8) from PEAK (
http://www.peak-system.com/fileadmin/media/linux/files/peak-linux-driver-7.8.tar.gz)
has the following in its peak_pci_tbl:

#define PEAK_PCI_DEVICE_ID   0x0001  // ID for PCI / PCIe Slot cards
#define PEAK_PCIE_CARD_ID    0x0002  // ID for PCIExpress Card
#define PEAK_PCIE_DEVICE_ID  0x0003  // ID for new PCIe Slot cards
#define PEAK_CPCI_ID         0x0004  // ID for new cPCI
#define PEAK_MINIPCI_ID      0x0005  // ID for miniPCI
#define PEAK_PC104PLUS_ID    0x0006  // ID for new PC-104 Plus
#define PEAK_PC104E_ID       0x0007  // ID for PC-104 Express
#define PEAK_MINIPCIE_ID     0x0008  // ID for miniPCIe Slot cards


Is there any reason why these all shouldn't also be in Xenomai's version?

If those cards are compatible with the ones we already support, you can
go ahead and send a patch to add the IDs to Xenomai's driver. But I
would first cross-check with the kernel commits that added support for
them, if more was changed.

Some of these cards are available with more than two channels. It would
be nice to update the driver to support up to 4 channels. Should not be
a big deal to port the relevant code from the Linux driver, though.

"lspci" list different PCI device IDs for the cards on the old and new
system. The new card with the ID 001c:0008 is not (yet) supported.

As this new card is already supported in the mainline Linux driver [1],
does have just two channels and does not need special handling, simply
adding that vendor:device ID here should work:
