Pci Question
Hi Im trying to write a userland program that writes to the IOPORT BAR's of a pci card. I can find the card and all that fine. But im a bit lost on exactly what address the IOPORT BAR's would be then? Im using the /dev/pci and pci(4) functions to find the card. Ive seen in the linux version of those code, that they take the base_address's and then ~0x03 them, and use that value for reading and writing with inb_l and outb_l. Ive tried using that on FreeBSD, but with outl and inl, as well as writel and readl, but I keep getting Bus error. Is there perhaps something that I am missing or forgetting, also im running the program as root. If anyone has any suggestions, they would be most welcome.

Re: Pci Question
Err, sorry. I meant the linux version of this is using outl_p to communicate with the device, and write the values. /Cole - Original Message - From: Cole [EMAIL PROTECTED] To: freebsd-hackers@freebsd.org Sent: Thursday, May 05, 2005 12:04 PM Subject: Pci Question Hi Im trying to write a userland program that writes to the IOPORT BAR's of a pci card.
