The QEMU project is currently moving its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting the bug state to "Incomplete" now.
If the bug has already been fixed in the latest upstream version of QEMU, then please close this ticket as "Fix released". If it is not fixed yet and you think that this bug report here is still valid, then you have two options: 1) If you already have an account on gitlab.com, please open a new ticket for this problem in our new tracker here: https://gitlab.com/qemu-project/qemu/-/issues and then close this ticket here on Launchpad (or let it expire auto- matically after 60 days). Please mention the URL of this bug ticket on Launchpad in the new ticket on GitLab. 2) If you don't have an account on gitlab.com and don't intend to get one, but still would like to keep this ticket opened, then please switch the state back to "New" or "Confirmed" within the next 60 days (other- wise it will get closed as "Expired"). We will then eventually migrate the ticket automatically to the new system (but you won't be the reporter of the bug in the new system and thus you won't get notified on changes anymore). Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1900919 Title: PXB selected as root bus incorrectly Status in QEMU: Incomplete Bug description: release: 4c41341af76cfc85b5a6c0f87de4838672ab9f89 qdev_device_add() will search for the "closest" bus possible, and bail out early if that bus is a root bus. pxb devices are considered root buses and so if you either 1. Add a PCI device on the QEMU command line *after* a pxb device, or 2. Add an integrated PCI device (like a watchdog) #1: -device pxb-pcie,id=cxl.0,bus=pcie.0,bus_nr=52 -device ahci,id=sata0,addr=0x8 #2: -watchdog i6300esb -device pxb-pcie,id=cxl.0,bus=pcie.0,bus_nr=52 The PXB will get selected as the bus (instead of the real root bus) and this will cause an assertion failure with the message like "qemu- system-x86_64: -device ahci,id=sata0,addr=0x8: PCI: Only PCI/PCIe bridges can be plugged into pxb-pcie" I think this is relatively solvable in the code base by determining if a bus is an expander, and skipping it if so. However, I wonder if it makes more sense to just allow expanders to have endpoint devices. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1900919/+subscriptions
