"pci_hp_register failed with error -16" was found in Guest when launching VM with pci-bridge and "-machine q35"
Description of problem:
Host and guest config file configuration:
CONFIG_HOTPLUG_PCI_CPCI=y
CONFIG_HOTPLUG_PCI_CPCI_ZT5550=m
CONFIG_HOTPLUG_PCI_CPCI_GENERIC=m
CONFIG_HOTPLUG_PCI_SHPC=y
Use this configuration kernel to boot QEMU, with the QEMU parameter "-machine q35 -device pci-bridge,id=bridge0,chassis_nr=1". After the guest boot, dmesg will display "shpchp 0000:00:04.0: pci_hp_register failed with error -16".
Steps to reproduce:
1.Boot QEMU
2.Check dmesg in VM
Additional information:
Error log:
[root@localhost ~]# dmesg | grep pci_hp_register
