The test uses QMP introspection to find PCI devices, then tries to
cold-plug each of them. Could be extended to hot-plug and unplug.
The tests' QMP introspection part is patterned after Andreas's
qom-test, which uses QMP to find machine types.
The following devices pass the test:
AC97 ich9-ahci pcnet
ES1370 ich9-intel-hda piix3-ide
VGA ich9-usb-ehci1 piix3-ide-xen
am53c974 ich9-usb-ehci2 piix3-usb-uhci
cirrus-vga ich9-usb-uhci1 piix4-ide
dc390 ich9-usb-uhci2 piix4-usb-uhci
e1000 ich9-usb-uhci3 pvscsi
e1000-82540em ich9-usb-uhci4 qxl-vga
e1000-82544gc ich9-usb-uhci5 rtl8139
e1000-82545em ich9-usb-uhci6 sdhci-pci
edu intel-hda secondary-vga
i6300esb ioh3420 tpci200
i82550 lsi53c810 usb-ehci
i82551 lsi53c895a virtio-balloon-pci
i82557a megasas virtio-blk-pci
i82557b megasas-gen2 virtio-net-pci
i82557c ne2k_pci virtio-rng-pci
i82558a nec-usb-xhci virtio-scsi-pci
i82558b nvme virtio-serial-pci
i82559a pci-bridge vmware-svga
i82559b pci-ohci vmxnet3
i82559c pci-serial vt82c686b-usb-uhci
i82559er pci-serial-2x x3130-upstream
i82562 pci-serial-4x xen-pvdevice
i82801 pci-testdev xio3130-downstream
i82801b11-bridge
Many of them are not currently tested at all.
This test does everything a number of existing tests currently do:
ac97-test.c e1000-test.c es1370-test.c eepro100-test.c
ne2000-test.c nvme-test.c pcnet-test.c rtl8139-test.c
tpci200-test.c virtio-balloon-test.c virtio-rng-test.c
vmxnet3-test.c
They are all marked "TODO: Replace with functional tests". Options
* Delete them now, undelete when we add functional tests
* Keep them, blacklist the devices in pci-devs-test.c
* Live with the duplicated testing
Andreas, I guess you got an opinion here.
There's overlap with a few others:
i82801b11-test.c usb-hcd-ehci-test.c usb-hcd-ohci-test.c
usb-hcd-xhci-test.c virtio-blk-test.c virtio-net-test.c
virtio-scsi-test.c virtio-serial-test.c
Options:
* Blacklist the devices in pci-devs-test.c
* Live with the duplicated testing
Andreas?
I manually blacklisted devices unavailable with -device, because QMP
introspection can't tell (pity).
I further blacklisted devices that require a suitable host device to
pass through:
kvm-pci-assign vhost-scsi-pci xen-pci-passthrough
vfio-pci
I blacklisted virtio-9p-pci and ivshmem for now, because they require
funky backends.
I blacklisted qxl and xen-platform, because they fail the test.
The test runs only for the x86 targets, just like all of
$(check-qtest-pci-y). It could run on other targets, as long as we
can find a machine type with a PCI bus.
