Goal

This document explain how to enable PCI hotplug debug at Operating System level.

Solution

Edit the /etc/system file and reboot the domain to enable PCI hotplug debug.

### usually you want the following to be enable but is optional if only ddi you are interested
set obpdebug=1
set snooping=1
set snoop_interval=90000000
set pcie:pcie_debug_flags= 0x1
set pcie:pcie_dbg_print= 0x1
set pcicfg:pcicfg_debug= 0x1
set pcicfg:pcicfg_dump_fcode= 0x1

#
#
#

### the follwoing ddidebug will need to match the following debugging flags in hex
set ddidebug=0x100000
