[PATCH v2 0/2] hw/nvme: add monitor commands for inspecting state

[Mateusz Nowicki <mateusz.nowicki@posteo.net>]

Add two HMP commands for inspecting emulated NVMe controllers from
the QEMU monitor without attaching gdb to the QEMU process:

  - 'info nvme'        - per-controller summary (PCI, identify
                         fields, CC/CSTS/AQA, queue counts)
  - 'info nvme-queues' - per-queue listing of admin and I/O SQ/CQ
                         (size, head/tail, PRP1, doorbell offset,
                         phase tag)

Useful for verifying queue setup, doorbell rings, AERs held in the
admin SQ and similar driver/controller interaction details from a
running QEMU monitor.

Changes in v2:
  - hw/nvme/meson.build: add the missing trailing newline (Markus).
  - Pick up Acked-by tags from Dr. David Alan Gilbert and Markus
    Armbruster on both patches.
