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

[Toomas Soome]

** Description changed:

  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.
