    space of the PCI bus
     
    

    SYNOPSIS

    #include <linux/bios32.h>

    int pcibios_read_config_dword (unsigned char bus, unsigned char device_fn,unsigned char where, unsigned int * value);  

    DESCRIPTION

    The pcibios_read_config_dword function reads a double word from the configuration space of the PCI bus. The bus can be specified with the bus parameters. The device_fn paramter determines which ? to use. where is set to the ?. After the call is made, value points to the value that was read.

    The return value is taken from the PCI controller in a way that I'm not quite sure of.

    If the PCI system is unavailable, PCIBIOS_FUNC_NOT_SUPPORTED is returned.
