[PATCH 0/5] Fix Q35 ACPI PCI Hot-plug I/O issues |

Attempt [1] to fix I/O allocation with the 'reserve-io' hint on each
pcie-root-port resulted in regression [2-3]. This patchset aims to fix
it by addressing the root cause of the problem - the disabled PCIe
Slot HPC bit.

[2] https://gitlab.com/qemu-project/qemu/-/issues/641
[3] https://bugzilla.redhat.com/show_bug.cgi?id=2006409
Julia Suvorova (5):
hw/pci/pcie_port: Rename 'native-hotplug' to 'native-hpc-bit'
hw/acpi/ich9: Add compatibility option for 'native-hpc-bit'
bios-tables-test: Allow changes in DSDT ACPI tables
hw/i386/acpi-build: Deny control on PCIe Native Hot-plug in _OSC
bios-tables-test: Update golden binaries
