Hello,
Is it possible to address PCI directly without running PCI card driver.
My baxsic requirement is,
I am presently using ISA card for communication & am directly addressing the
I/O ports & have written ISR ( in Qnx 4.25 using watcom C)
Now i want to use similarly for PCI card . Is it possible to do in QX
6.1/6.2 ?(without running PCcard driver)
Can any body give some info, reference in this regard
Yes you can access IO mapped memory in QNX 6 - look at:
ThreadCtl()
(http://www.qnx.com/developer/docs/momentics_nc_docs/neutrino/lib_ref/t/thre
adctl.html)
and in8(), in16(), in32(), out8()…

PCCard driver is for PCMCIA card. PCI Server is for PCI card.
In general yes you need the pci server running because though the program
that you can obtain which address and IRQ the card was assigned by the BIOS.
