For this we need to know which bugs are still valid and which co= uld be closed already. Thus we are setting older bugs to "Incomplete" now. If you still think this bug report here is valid, then please switch the st= ate back to "New" within the next 60 days, otherwise this report will be ma= rked as "Expired". Or mark it as "Fix Released" if the problem has been sol= ved with a newer version of QEMU already. Thank you and sorry for the incon= venience. ** Changed in: qemu Status: New =3D> 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/1747393 Title: nvme is missing support for NVME_ADM_CMD_ASYNC_EV_REQ Status in QEMU: Incomplete Bug description: NVME_ADM_CMD_ASYNC_EV_REQ is required by specification but apparently we will be responded by error when this command is used. The Asynchronous Event Request is a mandatory opcode required by specification (Figure 40, Section 5 in NVMe 1.2; Figure 41, Section 5 in NVMe 1.3). A simple way to deal with this in an emulator that doesn't really want to use async events is to queue up the requests and not do anything with them, and only complete them when the driver aborts the command.
