[RFC PATCH 0/5] Use ACPI PCI hot-plug for q35

[Julia Suvorova]

PCIe native hot-plug has numerous problems with racing events and unpredictable
guest behaviour (Windows). Switching to ACPI hot-plug for now.

Tested on RHEL 8 and Windows 2019.

pxb-pcie is not yet supported.

Julia Suvorova (5):
  hw/acpi/pcihp: Introduce find_host()
  hw/acpi/ich9: Trace ich9_gpe_readb()/writeb()
  hw/i386/acpi-build: Add ACPI PCI hot-plug methods to q35
  hw/i386/acpi-build: Turn off support of PCIe native hot-plug and SHPC
    in _OSC
  hw/acpi/ich9: Enable ACPI PCI hot-plug
