.SH "DESCRIPTION"
.PP
A PCI bus may host multiple slots, each slot may support a reset mechanism independent of other slots\&. For instance, some slots may support slot power control\&. In the case of a 1:1 bus to slot architecture, this function may wrap the bus reset to avoid spurious slot related events such as hotplug\&. Generally a slot reset should be attempted before a bus reset\&. All of the function of the slot and any subordinate buses behind the slot are reset through this function\&. PCI config space of all devices in the slot and behind the slot is saved before and restored after reset\&.
.PP
Return 0 on success, non\-zero on error\&.
