With this patch, we can see bus address of hotplug slots as follows: $ cat address 0000:0b:01 Signed-off-by: Kenji Kaneshige Signed-off-by: Greg Kroah-Hartman --- drivers/pci/hotplug/shpchp_core.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) --- gregkh-2.6.orig/drivers/pci/hotplug/shpchp_core.c +++ gregkh-2.6/drivers/pci/hotplug/shpchp_core.c @@ -65,6 +65,7 @@ static int get_power_status (struct hotp static int get_attention_status (struct hotplug_slot *slot, u8 *value); static int get_latch_status (struct hotplug_slot *slot, u8 *value); static int get_adapter_status (struct hotplug_slot *slot, u8 *value); +static int get_address (struct hotplug_slot *slot, u32 *value); static int get_max_bus_speed (struct hotplug_slot *slot, enum pci_bus_speed *value); static int get_cur_bus_speed (struct hotplug_slot *slot, enum pci_bus_speed *value); @@ -77,6 +78,7 @@ static struct hotplug_slot_ops shpchp_ho .get_attention_status = get_attention_status, .get_latch_status = get_latch_status, .get_adapter_status = get_adapter_status, + .get_address = get_address, .get_max_bus_speed = get_max_bus_speed, .get_cur_bus_speed = get_cur_bus_speed, }; @@ -314,6 +316,18 @@ static int get_adapter_status (struct ho return 0; } +static int get_address (struct hotplug_slot *hotplug_slot, u32 *value) +{ + struct slot *slot = get_slot (hotplug_slot, __FUNCTION__); + struct pci_bus *bus = slot->ctrl->pci_dev->subordinate; + + dbg("%s - physical_slot = %s\n", __FUNCTION__, hotplug_slot->name); + + *value = (pci_domain_nr(bus) << 16) | (slot->bus << 8) | slot->device; + + return 0; +} + static int get_max_bus_speed (struct hotplug_slot *hotplug_slot, enum pci_bus_speed *value) { struct slot *slot = get_slot (hotplug_slot, __FUNCTION__);
