[PATCH v2] hw/nvme: move nvme emulation out of hw/block |
|
Date: |
Mon, 1 Mar 2021 12:35:09 +0100 |
From: Klaus Jensen <k.jensen@samsung.com>
With the introduction of the nvme-subsystem device we are really
cluttering up the hw/block directory.
As suggested by Philippe previously, move the nvme emulation to
hw/nvme.
Suggested-by: Philippe Mathieu-Daudé <philmd@redhat.com>
Signed-off-by: Klaus Jensen <k.jensen@samsung.com>
---
v2:
* rebased on nvme-next
* got rid of the second patch (Minwoo)
