driver installation Sensoray 626 card

[Guest]

Hi,
I do not know if I am at the right place but I have a problem with the driver installation for the DAQ card.

root@ED209:/home/manikantan/Documents/s626_mar07# make

Want to know what the parts passing argument 2 of 'request_irq' from incompatible pointer type and implicit declaration of function 'pci_module_init' mean....

I am trying to compile and install drivers.

From the look of:

/home/manikantan/Documents/s626_mar07/s626drv.c:64:26: error: linux/config.h: No such file or directory

I'd say you have one of more dependent development library files missing or can't be found, does it come with a ./configure script? and if so have you run it to check system sanity?

Failing that can you point to a web site where the driver came from.

Re: driver installation Sensoray 626 card

Ok, just found and downloaded a copy...
The config.h file is because the name change in kernel 2.6.21 (I think) it's now called autoconf.h;
that isn't the only problem...a number of the API's used by this driver changed at the same time...

Re: driver installation Sensoray 626 card

Got it building...

In s626drv.c add/change just after all the ifdef DEBUG stuff

~~
#define DBGI(x...)
#endif

//Added for post-2.6.21 kernel
#ifndef SA_SHIRQ
#define SA_SHIRQ IRQF_SHARED
#endif

#ifndef pci_module_init
#define pci_module_init pci_register_driver
#endif

// The necessary header files
#include <linux/version.h>
#include <linux/autoconf.h>

~~
~~

I can't test if it works, but at least it now builds.

I quite enjoyed that little bit of exercise... got any more?

Re: driver installation Sensoray 626 card

Thanks a lot Windy...
It got it running and installed modules and other stuff
Now I am trying the make install function... Will tell you if I have any more problems

Windy...

I used your pointers and it helped me as well, thank you. but i am getting another warning; now i know its a warning but it seems like it might be kind of important. I have not hacked any C for a loooong time and certainly no kernel hacking; what do you make of this:

/sensoray/s626drv.c:964: warning: passing argument 2 of ‘request_irq’ from incompatible pointer type

969: request = request_irq (irq, handleallinterrupts, flags, board->name, dev_id)

handleallinterupts: static void handleallinterrupts( int irq, void *dev_id, struct pt_regs *regs)

the definition for request_irq is as follows:
int request_irq (unsigned int irq, void (*handler) (int, void *, struct pt_regs *), unsigned long irqflags, const char *devname, void *dev_id);

It looks like the second argument is expecting a pointer, but i cant seem to get a cast to respond properly; i may be asking a noobish question so please be nice

thanks in advance.

Re: driver installation Sensoray 626 card

From what I can see it just needs a cast on the interrupt handler (handleallinterrupts), something like this:

request = request_irq (irq, (void *)handleallinterrupts, flags, board->name, dev_id);

As before, I can't test it, so I'm not 100% certain...

Let me know if it works, these problems and changes need to be fed back to the suppliers; then they can fix things properly .
