Subject: [PATCH v2 00/17] hw/block/nvme: multiple namespaces support
Date: Fri, 18 Sep 2020 22:36:04 +0200	[thread overview]
Message-ID: <20200918203621.602915-1-its@irrelevant.dk> (raw)

From: Klaus Jensen <k.jensen@samsung.com>

This is the next round of my patches for the nvme device.

This includes a bit of cleanup and two new features:

  * support for scatter/gather lists

  * multiple namespaces support through a new nvme-ns device

Finally, the series wraps up with changing the PCI vendor and device ID to get
rid of the internal Intel id and as a side-effect get rid of some Linux kernel
quirks that no longer applies.

"pci: pass along the return value of dma_memory_rw" has already been posted by
Philippe in another series, but since it is not applied yet, I am including it
here.

Changes for v2
~~~~~~~~~~~~~~

  * Added a new patch ("hw/block/nvme: fix typo in trace event") that does what
    it says on the tin.

  * Dropped the "hw/block/nvme: support multiple parallel aios per request"
    patch (Keith).

  * hw/block/nvme: add symbolic command name to trace events
    Changed to single quote (Philippe)

  * hw/block/nvme: default request status to success
    Commit message typo fixed (Philippe)

  * hw/block/nvme: change controller pci id
    Do NOT bump the device id for the legacy Intel id (David)
