[PATCH 0/3] hw/pci: Consider reserved slots mask when checking PCI bus is full

Posted by Philippe Mathieu-Daudé 2 weeks, 5 days ago

Generic fix for the SPARC/Sabre issue reported by Thomas:
https://lore.kernel.org/qemu-devel/20260309181452.83702-1-thuth@redhat.com/
"hw/sparc64/sun4u: Mark unusable PCI busses as full to ease device plugging"

Philippe Mathieu-Daudé (3):
  hw/pci: Have various pci_bus*() methods take a const PCIBus argument
  hw/qdev: Introduce BusClass::is_full() handler
  hw/pci: Consider reserved slots mask when checking PCI bus is full
