Re: Regarding PCIe peek/poke in NetBSD

Hi Greg,

Thanks for the link, there i can found some useful information.

As we know that the 'pcictl' command will list all the pci devices
present in the system with corresponding device/vendor id.
The same way, is that possible to get/map the IO/Mem/prefetchable
region of any PCI device by using bus_space_map for Peek/Poke?

If so, please give guidance.

Thanks,
Gnana
