Hello there, Under linux, PCI stuff is generally done thru set of pci* functions, while under FreeBSD there are ioctls provided by pci driver. I've been doing some code migration from linux to FreeBSD, and got thru most of it, except for things like this one: <code ostype="linux"> . . . pcibios_read_config_dword(bus_id, func_id, PCI_BASE_ADDRESS_0, &addr_0); addr_0 &= PCI_BASE_ADDRESS_IO_MASK; pcibios_read_config_dword(bus_id, func_id, PCI_BASE_ADDRESS_1, &addr_1); addr_1 &= PCI_BASE_ADDRESS_MEM_MASK; . . . </code> I am not quite sure how to code the same thing under FreeBSD, particulary: pi.pi_width = 4; pi.pi_reg = <WHAT DO I PUT HERE?> ioctl(fd, PCIOCREAD, &pi); Could anyone give me an example for both addr_0 and addr_1 (that is, translation of the linux code I cited above?) I will really appreciate any help with regard to this. Thanks in advance. -- Alexey. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
