28074bb90dSTom Pothier *
29074bb90dSTom Pothier * hostbridge/pciexrc/pcibus topo nodes are created per SMBIOS type 138
30074bb90dSTom Pothier * (SUN_OEM_PCIEXRC) records. Each type 138 record can either represent
31074bb90dSTom Pothier * a hostbridge or a pciexrc/pcibus determined by whether it points to
32074bb90dSTom Pothier * a baseboard record or another type 138 record.
33074bb90dSTom Pothier *
34074bb90dSTom Pothier * x86pi_gen_hbr() is called when a new hostbridge node needs to be created..
35074bb90dSTom Pothier * It then searches all the type 138 records that connected to it. For each
36074bb90dSTom Pothier * of the records, bdf is compared to find a matching di_node. If the
37074bb90dSTom Pothier * di_node is a pciex root port, a pciexrc (bad name!) node will be created.
38074bb90dSTom Pothier * When pciexrc creation is done, or the di_node is a pcibus, in either
39074bb90dSTom Pothier * case the pcibus module will loaded to enumerate pciexbus/pcibus etc.
40074bb90dSTom Pothier *
41074bb90dSTom Pothier * The enumeration uses did routines heavily, which requires a did hash
42074bb90dSTom Pothier * pointer stored in x86pi's module-specific area.
