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]

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
