Subject: [RFC PATCH v2 0/4] Use ACPI PCI hot-plug for q35
Date: Tue, 18 Aug 2020 23:52:23 +0200	[thread overview]
Message-ID: <20200818215227.181654-1-jusual@redhat.com> (raw)

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.

v2:
    * new ioport range for acpiphp [Gerd]
    * drop find_pci_host() [Igor]
    * explain magic numbers in _OSC [Igor]
    * drop build_q35_pci_hotplug() wrapper [Igor]

Julia Suvorova (4):
  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
