[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 3/6] pci: switch pci_conf_read32 to use pci_sbdf_t
This reduces the number of parameters of the function to two, and
simplifies some of the calling sites.
While there convert {IGD/IOH}_DEV to be a pci_sbdf_t itself instead of
a device number.
