# nvme traces for successful events
hw/block/nvme: support multiple namespaces This adds support for multiple namespaces by introducing a new 'nvme-ns' device model. The nvme device creates a bus named from the device name ('id'). The nvme-ns devices then connect to this and registers themselves with the nvme device. This changes how an nvme device is created. Example with two namespaces: -drive file=nvme0n1.img,if=none,id=disk1 -drive file=nvme0n2.img,if=none,id=disk2 -device nvme,serial=deadbeef,id=nvme0 -device nvme-ns,drive=disk1,bus=nvme0,nsid=1 -device nvme-ns,drive=disk2,bus=nvme0,nsid=2 The drive property is kept on the nvme device to keep the change backward compatible, but the property is now optional. Specifying a drive for the nvme device will always create the namespace with nsid 1.

hw/block/nvme: add metadata support Add support for metadata in the form of extended logical blocks as well as a separate buffer of data. The new `ms` nvme-ns device parameter specifies the size of metadata per logical block in bytes. The `mset` nvme-ns device parameter controls whether metadata is transfered as part of an extended lba (set to '1') or in a separate buffer (set to '0', the default). Regardsless of the scheme chosen with `mset`, metadata is stored at the end of the namespace backing block device. This requires the user provided PRP/SGLs to be walked and "split" into data and metadata scatter/gather lists if the extended logical block scheme is used, but has the advantage of not breaking the deallocated blocks support.

hw/block/nvme: end-to-end data protection Add support for namespaces formatted with protection information. The type of end-to-end data protection (i.e. Type 1, Type 2 or Type 3) is selected with the `pi` nvme-ns device parameter. If the number of metadata bytes is larger than 8, the `pil` nvme-ns device parameter may be used to control the location of the 8-byte DIF tuple. The default `pil` value of '0', causes the DIF tuple to be transferred as the last 8 bytes of the metadata. Set to 1 to store this in the first eight bytes instead.

The `mset` nvme-ns device parameter controls whether metadata is transfered as part of an extended lba (set to '1') or in a separate buffer (set to '0', the default). Regardsless of the scheme chosen with `mset`, metadata is stored at the end of the namespace backing block device. This requires the user provided PRP/SGLs to be walked and "split" into data and metadata scatter/gather lists if the extended logical block scheme is used, but has the advantage of not breaking the deallocated blocks support.

A qcow2 image, uses a cluster size of 64KiB by default and blocks will only be marked deallocated if a full cluster is zeroed or discarded. However, this *is* consistent with the spec since Write Zeroes "should" deallocate the block if the Deallocate attribute is set and "may" deallocate if the Deallocate attribute is not set.

hw/block/nvme: support namespace attachment command This patch supports Namespace Attachment command for the pre-defined nvme-ns device nodes. Of course, attach/detach namespace should only be supported in case 'subsys' is given. This is because if we detach a namespace from a controller, somebody needs to manage the detached, but allocated namespace in the NVMe subsystem. As command effect for the namespace attachment command is registered, the host will be notified that namespace inventory is changed so that host will rescan the namespace inventory after this command. For example, kernel driver manages this command effect via passthru IOCTL.

hw/block/nvme: Support Zoned Namespace Command Set The emulation code has been changed to advertise NVM Command Set when "zoned" device property is not set (default) and Zoned Namespace Command Set otherwise. Define values and structures that are needed to support Zoned Namespace Command Set (NVMe TP 4053) in PCI NVMe controller emulator. Define trace events where needed in newly introduced code. In order to improve scalability, all open, closed and full zones are organized in separate linked lists. Consequently, almost all zone operations don't require scanning of the entire zone array (which potentially can be quite large) - it is only necessary to enumerate one or more zone lists. Handlers for three new NVMe commands introduced in Zoned Namespace Command Set specification are added, namely for Zone Management Receive, Zone Management Send and Zone Append. Device initialization code has been extended to create a proper configuration for zoned operation using device properties. Read/Write command handler is modified to only allow writes at the write pointer if the namespace is zoned. For Zone Append command, writes implicitly happen at the write pointer and the starting write pointer value is returned as the result of the command. Write Zeroes handler is modified to add zoned checks that are identical to those done as a part of Write flow. Subsequent commits in this series add ZDE support and checks for active and open zone limits.

hw/block/nvme: align zoned.zasl with mdts ZASL (Zone Append Size Limit) is defined exactly like MDTS (Maximum Data Transfer Size), that is, it is a value in units of the minimum memory page size (CAP.MPSMIN) and is reported as a power of two. The 'mdts' nvme device parameter is specified as in the spec, but the 'zoned.append_size_limit' parameter is specified in bytes. This is suboptimal for a number of reasons: 1. It is just plain confusing wrt. the definition of mdts. 2. There is a lot of complexity involved in validating the value; it must be a power of two, it should be larger than 4k, if it is zero we set it internally to mdts, but still report it as zero. 3. While "hw/block/nvme: improve invalid zasl value reporting" slightly improved the handling of the parameter, the validation is still wrong; it does not depend on CC.MPS, it depends on CAP.MPSMIN. And we are not even checking that it is actually less than or equal to MDTS, which is kinda the *one* condition it must satisfy. Fix this by defining zasl exactly like mdts and checking the one thing that it must satisfy (that it is less than or equal to mdts). Also, change the default value from 128KiB to 0 (aka, whatever mdts is). Signed-off-by: Klaus Jensen <k.jensen@samsung.com> Reviewed-by: Keith Busch <kbusch@kernel.org>

hw/block/nvme: refactor the logic for zone write checks Refactor the zone write check logic such that the most "meaningful" error is returned first. That is, first, if the zone is not writable, return an appropriate status code for that. Then, make sure we are actually writing at the write pointer and finally check that we do not cross the zone write boundary. This aligns with the "priority" of status codes for zone read checks. Also add a couple of additional descriptive trace events and remove an always true assert.

hw/block/nvme: Support Zoned Namespace Command Set The emulation code has been changed to advertise NVM Command Set when "zoned" device property is not set (default) and Zoned Namespace Command Set otherwise. Define values and structures that are needed to support Zoned Namespace Command Set (NVMe TP 4053) in PCI NVMe controller emulator. Define trace events where needed in newly introduced code. In order to improve scalability, all open, closed and full zones are organized in separate linked lists. Consequently, almost all zone operations don't require scanning of the entire zone array (which potentially can be quite large) - it is only necessary to enumerate one or more zone lists. Handlers for three new NVMe commands introduced in Zoned Namespace Command Set specification are added, namely for Zone Management Receive, Zone Management Send and Zone Append. Device initialization code has been extended to create a proper configuration for zoned operation using device properties. Read/Write command handler is modified to only allow writes at the write pointer if the namespace is zoned. For Zone Append command, writes implicitly happen at the write pointer and the starting write pointer value is returned as the result of the command. Write Zeroes handler is modified to add zoned checks that are identical to those done as a part of Write flow.

hw/block/nvme: Support Zone Descriptor Extensions Zone Descriptor Extension is a label that can be assigned to a zone. It can be set to an Empty zone and it stays assigned until the zone is reset. This commit adds a new optional module property, "zoned.descr_ext_size". Its value must be a multiple of 64 bytes. If this value is non-zero, it becomes possible to assign extensions of that size to any Empty zones. The default value for this property is 0, therefore setting extensions is disabled by default.

Note that the LPA field in the Identify Controller data structure intentionally has bit 0 cleared because there is no namespace specific information in the SMART / Health information log page.

# xen-block.c
xen: introduce 'xen-block', 'xen-disk' and 'xen-cdrom' This patch adds new XenDevice-s: 'xen-disk' and 'xen-cdrom', both derived from a common 'xen-block' parent type. These will eventually replace the 'xen_disk' (note the underscore rather than hyphen) legacy PV backend but it is illustrative to build up the implementation incrementally, along with the XenBus/XenDevice framework. Subsequent patches will therefore add to these devices' implementation as new features are added to the framework. After this patch has been applied it is possible to instantiate new 'xen-disk' or 'xen-cdrom' devices with a single 'vdev' parameter, which accepts values adhering to the Xen VBD naming scheme [1]. For example, a command-line instantiation of a xen-disk can be done with an argument similar to the following: -device xen-disk,vdev=hda The implementation of the vdev parameter formulates the appropriate VBD number for use in the PV protocol.

xen: add xenstore watcher infrastructure A Xen PV frontend communicates its state to the PV backend by writing to the 'state' key in the frontend area in xenstore. It is therefore necessary for a XenDevice implementation to be notified whenever the value of this key changes. This patch adds code to do this as follows: - an 'fd handler' is registered on the libxenstore handle which will be triggered whenever a 'watch' event occurs - primitives are added to xen-bus-helper to add or remove watch events - a list of Notifier objects is added to XenBus to provide a mechanism to call the appropriate 'watch handler' when its associated event occurs The xen-block implementation is extended with a 'frontend_changed' method, which calls as-yet stub 'connect' and 'disconnect' functions when the relevant frontend state transitions occur. A subsequent patch will supply a full implementation for these functions.

xen: automatically create XenBlockDevice-s This patch adds create and destroy function for XenBlockDevice-s so that they can be created automatically when the Xen toolstack instantiates a new PV backend via xenstore. When the XenBlockDevice is created this way it is also necessary to create a 'drive' which matches the configuration that the Xen toolstack has written into xenstore. This is done by formulating the parameters necessary for each 'blockdev' layer of the drive and then using qmp_blockdev_add() to create the layers. Also, for compatibility with the legacy 'xen_disk' implementation, an iothread is automatically created for the new XenBlockDevice. This, like the driver layers, will be destroyed after the XenBlockDevice is unrealized. The legacy backend scan for 'qdisk' is removed by this patch, which makes the 'xen_disk' code is redundant. The code will be removed by a subsequent patch.
