Linux NI-VXI lockup on unload_vxi

This error is almost certainly related to a 3rd party system (Mercury Computers VantageRT DSP board), but I'd like to know if it is possible to avoid the reboot necessary to fix the problem.

Background: I've been working with Mercury to be able to access VXI addresses via PCI-MXI-2 mappings. The Mercury board occupies a PCI slot alongside the PCI-MXI-2 in a Linux PC. We have NI-VXI 2.0 for Linux. I have already had Discussion Board support for accessing PCI->VXI mapping registers of PCI-MXI-2 card, and with that info wrote a learning/test program the scans for LA slots and decodes the configuration registers. This works fine and I have confidence in being able to access various VXI hardware. My problem comes about when I load and configure the Mercury driver(s). There is some horrible interaction between their code and the ni-vxi and/or pci-mxi-2. If their driver is ever loaded, I cannot make any ni-vxi stuff (resman, vxiedit, my program) work, and if I dare to try to unload the vxi driver in hopes of resetting everything, my Linux PC locks up and must be rebooted.

What follows is a copy of support request email sent to Mercury.

-----------------
More info on my crashes with NI-VXI software & Mercury interaction.

Here's the output of a session I just ran from a freshly rebooted machine. You can see that I loaded the NI-VXI device driver, successfully ran my program (and I can run it many times with exact same results, right up until I run configmc), then ran configmc, then tried my code again with the resulting bus error. Since I have been doing VXI stuff for some weeks now and ni-vxi has supported Linux since redhat 5.0, and it all works fine until configmc is done, I must initially suspect a Mercury-related problem. I just don't think Mercury stuff is playing well with others.

At this point, I will generally have to reboot the PC to recover NI-VXI functionality.

Mike,

Did Mercury give you any information about it's interaction with the NI-VXI driver?

I just got off the phone with a long conference call with two Mercury support engineers. Short answer is I am in the same boat I was in before. Long answer is that many things were tried, and they all boiled down to nothing but locking up my machine. We have found that in a surprising turn of events this sequence causes bad things too:

(On a freshly rebooted system, and ./vxi is a simple program I wrote that uses LPeek to get the translation windows, opens A16 space and looks for LAs and configuration registers to decode -- source code attached, but your web page thinks it's binary!).

The crictical point here is that the code ran once fine, but a second time kills the system (well, if I ever want VXI access again). I note that lspci tells me that the PCI-MXI-2 card memory is disabled now! I can run my vxi program multiple times without problem if I have never done configmc. If I load the vxi driver first, then run configmc, my vxi program will not work even once.

Does the NIVXI driver module make any assumptions about state of PCI bus configuration that might be invalidated by Mercury's drivers? Does my code (source attached) violate any PCI-MXI-2 interface requirements? Why might my program work fine for many runs, but never more than once if Mercury configuration is run? Are there any debugging flags I could put on the driver?

Since this is obviously and interaction issue, everyone will want to blame everyone else. Meanwhile, I'm stuck. So if there's any insight into what the NIVXI driver is doing and/or assumptions it might make, I can relay them to Mercury to see if they are violating anything.

I became concerned that it could be my program causing the problems, so I decided to use an example program provided by National Instruments that my code was ultimately based on. On a fresh rebooted system , I ran the commands below

lspci -v
cd /usr/local/nivxi/sys/
sudo ./load_vxi
lspci -v
/usr/local/nivxi/examples/vxilow
lspci -v
cd ~
configmc -cf vantagert_ppc.cfg init
lspci -v
/usr/local/nivxi/examples/vxilow

The full output follows and is fairly long due to the multiple lspci outputs, so read carefully. The thing I note is that after configmc is run, the PCI-MXI-2 card is listed by lspci as being disabled (and immediately after configmc, no intervening vxi programs). So it's not just some issue with the vxi driver, unless something configmc does causes the vxi driver to disable the card.
