[Bug 1747393] Re: nvme is missing support for NVME_ADM_CMD_ASYNC_EV_REQ

[Thomas Huth]

The QEMU project is currently considering to move 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 older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

** Changed in: qemu
       Status: New => Incomplete

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.
