[Qemu-devel] When is PCIUnregisterFunc called?

[Huaicheng Li]

Hi QEMU developers,

I'm trying to inject some operations during the emulated device teardown
phase.

For an emulated PCIe device, such as NVMe or IVSHMEM, I notice that QEMU
registers PCIDeviceClass pc->init and pc->exit functions for that device.
->init() (e.g. nvme_init(), or ivshmem_init()) are marked as constructors
and called before QEMU main() runs. However, I failed to find when the
->exit() function is called. When I add some printf() into the ->exit()
func, it's not even printed. Could anyone give any pointers on this?

Thanks.

Best,
Huaicheng
