The user mentioned an assertion failure when hot-unplugging a virtio iommu enabled device. Let me break down the details. - -The error happens during device removal, specifically when using the 'device_del' command via QMP. The crash occurs in memory.c at line 2818, where the assertion `QTAILQ_EMPTY(&as->listeners)` fails. This suggests that there are listeners still attached to an address space after it's being destroyed. - -Looking into the commit mentioned, "use RCU for list of children of a bus", I recall that RCU (Read-Copy-Update) is used for managing concurrent access to data structures. Maybe the issue is related to how device removal interacts with these structures. - -The failing assertion is about listeners not being properly removed when a device is deleted. This likely ties into how devices are managed in QEMU, especially when hot-unplugging. Since it's a virtio-net-pci device using iommu_platform=on and ats=on, the problem might be specific to how these features handle device removal. - -The categories provided include 'device' as one of them. Given that the issue arises from removing a device and relates to listeners in memory management, which is part of device handling, I think the appropriate category here is 'device'. It's not about translation, assembly lowering, or something else like graphics or network specifically (though it does involve networking via virtio-net). The core problem seems to be with device management. -</think> - -The bug report involves an assertion failure when removing a device, particularly related to listeners in memory management during hot-unplugging. This points to an issue within the device management code, making 'device' the appropriate category. - -**Answer:** device \ No newline at end of file |
