Hi,
We use camera acquisition PCI cards and I initialise these cards with
:
- pci_find_device(VENDORID,DEVICEID,struct pci_dev *dev)
- pci_read|write_config_xxx(struct pci_dev *dev,PCI_OFFSET_CONFIG,&data)
- remap_address = ioremap_nocache(PCI_IO|MEM,SIZE)
then
- rt_request_global_irq(dev->irq,Irq_handler)
- rt_enable_irq(dev->irq)
and then use IO remap to drive your PCI card.
( you can use pci_read|write_config_xxx(struct pci_dev
*dev,PCI_OFFSET_CONFIG,&data)
to configure bus-masters without problem in rt_tasks )
rt_functions are for RTAI but should have equivalent with RTlinux.
Chris.
