Talking to PCI board

I want to develop a driver to communicate with a PCI board that will be
connected to a device that provides me with a regular time indicator via
the PCI registers.

So, I checked out all the doc that I could find on the QNX site but nothing
about developing a driver to access the PCI bus to read a PCI register
of an arbitrary PCI device. I found references about Audio, Graphics,
Input, Network and USB, but none about a generic PCI device.

I need a template to using the PCI registers of an arbitrary PCI device.
This certainly exists but I could not find anywhere on the site by searching
it.

The board that I am using is a PCI9030 assembled by
PLX Technology at www.plxtech.com. They provide me with driver
implementations for Windows and Linux (2.2 and 2.4 kernels).


I appreciate any help you give to me,

Thanks,

Andre

Look at the pci_*() functions.

For instance:

First steps:
ThreadCtrl(_NTO_TCTL_IO, 0) - allows the application IO privilige:
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/t/threadctl.html

For PCI plug and play functionality:
pci_attach() - for connecting to the PCI sub-system:
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/p/pci_attach.html

pci_attach_device() - for finding and retrieving PCI device information:
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/p/pci_attach_device.html

pci_detach() - disconnects from PCI sub-system:
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/p/pci_detach.html

Memory mapping:
mmap_device_memory() - for mapping PCI device memory into virtual memory
space:
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/m/mmap_device_memory.html

IO:
in8() - reads 8 bit IO
in16() - 16 bit
in32() - 32 bit
out8() - write 8 bit IO
out16() - 16 bit
out32() - 32 bit
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/i/in8.html

Interrupt:
InterruptAttach() - sets up traditional ISR
http://www.qnx.com/developer/docs/momentics621_docs/neutrino/lib_ref/i/interruptattach.html

InterruptAttachEvent() - sets up an event based ISR, which run in user
space. This is slower than the traditional ISR method.

What can I do if I am using QNX4?

Maybe you were looking for something a little more too specific. Under QNX4
a driver is just like a normal program. Just need to be linked with -T1.
As for getting info about PCI look for CA_PCI_* fonctions.

All the doc you found on are mostly about QNX6, beware.

Thanks, I just found how to access it using CA_PCI_* and using inp() to read
from an address, it is working
so I am getting the values I need.

Now I must install a handler to listen to interrupts, do you know how to do
that?

Thanks,

Andre
