The 'nvme_map_sgl' method has a 256 element array used for copying
data from the device. Skip the automatic zero-init of this array
to eliminate the performance overhead in the I/O hot path.
The 'segment' array will be fully initialized when reading data from
the device.
The 'nme_changed_nslist' method has a 4k byte array that is manually
initialized with memset(). The compiler ought to be intelligent
enough to turn the memset() into a static initialization operation,
and thus not duplicate the automatic zero-init. Replacing memset()
with '{}' makes it unambiguous that the array is statically initialized.

The nvme_aio_err() does not handle Verify, Compare, Copy and other misc

Device Error. For some of these commands, we know better, so set it
explicitly.
For the commands using the nvme_misc_cb() callback (Copy, Flush, ...),
if no status code has explicitly been set by the lower handlers, default
to Internal Device Error as previously.

The Open Compute Project [1] includes a Datacenter NVMe
SSD Specification [2]. The most recent version of this specification
(as of November 2024) is 2.6.1. This specification layers on top of
the NVM Express specifications [3] to provide additional
functionality. A key part of of this is the 512 Byte OCP SMART / Health
Information Extended log page that is defined in Section 4.8.6 of the
specification.
We add a controller argument (ocp) that toggles on/off the SMART log
extended structure. To accommodate different vendor specific specifications
like OCP, we add a multiplexing function (nvme_vendor_specific_log) which
will route to the different log functions based on arguments and log ids.
We only return the OCP extended SMART log when the command is 0xC0 and ocp
has been turned on in the nvme argumants.
Though we add the whole nvme SMART log extended structure, we only populate
the physical_media_units_{read,written}, log_page_version and
log_page_uuid.
This patch is based on work done by Joel but has been modified enough
that he requested a co-developed-by tag rather than a signed-off-by.

The opaque pointers passed to ObjectProperty callbacks are
the last instances of non-const Property pointers in the tree.

Make sure we grab a reference on the subsystem when a VF is realized.
Otherwise, the subsytem will be unrealized automatically when the VFs

This fixes a latent bug but was not exposed until commit 08f632848008
("pcie: Release references of virtual functions"). This was then fixed
(or rather, hidden) by commit c613ad25125b ("pcie_sriov: Do not manually

b0fdaee5d1ed, exposing the bug yet again.

If a host chooses to use the SQHD "hint" in the CQE to know if there is
room in the submission queue for additional commands, it may result in a
situation where there are not enough internal resources (struct
NvmeRequest) available to process the command. For a lack of a better
term, the host may "over-commit" the device (i.e., it may have more
inflight commands than the queue size).
For example, assume a queue with N entries. The host submits N commands
and all are picked up for processing, advancing the head and emptying
the queue. Regardless of which of these N commands complete first, the
SQHD field of that CQE will indicate to the host that the queue is
empty, which allows the host to issue N commands again. However, if the
device has not posted CQEs for all the previous commands yet, the device
will have less than N resources available to process the commands, so
queue processing is suspended.
And here lies an 11 year latent bug. In the absense of any additional
tail updates on the submission queue, we never schedule the processing
bottom-half again unless we observe a head update on an associated full
completion queue. This has been sufficient to handle N-to-1 SQ/CQ setups
(in the absense of over-commit of course). Incidentially, that "kick all
associated SQs" mechanism can now be killed since we now just schedule
queue processing when we return a processing resource to a non-empty
submission queue, which happens to cover both edge cases. However, we
must retain kicking the CQ if it was previously full.
So, apparently, no previous driver tested with hw/nvme has ever used
SQHD (e.g., neither the Linux NVMe driver or SPDK uses it). But then OSv
shows up with the driver that actually does. I salute you.

Adds support for the controller atomic parameters: AWUN and AWUPF. Atomic
Compare and Write Unit (ACWU) is not currently supported.
Writes that adhere to the ACWU and AWUPF parameters are guaranteed to be atomic.
New NVMe QEMU Parameters (See NVMe Specification for details):
atomic.dn (default off) - Set the value of Disable Normal.
atomic.awun=UINT16 (default: 0)
atomic.awupf=UINT16 (default: 0)
By default (Disable Normal set to zero), the maximum atomic write size is
set to the AWUN value. If Disable Normal is set, the maximum atomic write
size is set to AWUPF.

The allocated memory to hold LBA ranges leaks in the nvme_dsm function. This
happens because the allocated memory for iocb->range is not freed in all
error handling paths.
Fix this by adding a free to ensure that the allocated memory is properly freed.
