79745b8c8b blobstore: do not allow for spdk_bs_unload if blobs are still open
It is possible that a user will call spdk_bs_unload() with blobs
list not-empty. Instead of just asserting that, now the call fails
with appropriate error.

3f9cbe513b blob: add write_zeroes support
Unmap does not guarantee that erased blocks will return all zeroes.
using write_zeroes when unmapping metadata gives the
desired behavior for a blob.

Only metadata pages will be cleared with write_zeroes in this patch;
blob data clusters will still call unmap.  This behavior may be made
configurable in a later patch (to allow the user to request zeroing of
clusters rather than just unmapping).

2df9f03c47 blobstore: New API call to destroy blobstore [1/3]
Currently exposed API allows to load/unload and to
initialize blobstore on a device.

A spdk_bs_destroy() call is added in order to reach
functional parity with spdk_bs_init(). It was not
possible to remove blobstore from device from within
SPDK previously.

spdk_bs_destroy() takes blobstore pointer as argument
(instead of bs_dev), because blobstore has to be already
loaded to destroy it.

f97c8b3142 lvol: add spdk_lvs_opts_init()
Some future patches will require specifying an lvol_store
name when calling spdk_lvs_init().  This means that passing
NULL for spdk_lvs_opts will no longer be an option.  So
add an spdk_lvs_opts_init() (similar to spdk_bs_opts_init)
which will initialize a default value for the cluster size.

While here, prepend an underscore to spdk_setup_lvs_opts, since
this function is not part of the public SPDK API.

Always start bdev pollers on the calling core.

This removes the lcore concept from the bdev poller abstraction and
simplifies the job of spdk_bdev_initialize() callers providing their own
poller and event implementations.

All callers except the NVMe bdev hotplug poller already used the current
core as the parameter.  The NVMe HotplugPollCore option was undocumented
and unused in any of the tests or example configuration files, so it
should be safe to remove.

8b0a4a3c53 bdev_virtio: implement multiqueue
Virtqueues now have to be "acquired"
by a logical CPU core in order to
perform any traffic on them. The
acquire mechanism is thread-safe to
prevent two reactors accessing the
same virtqueue at the same time.

For now a single virtqueue
may be used by only one io_channel.
Support for shared virtqueues will
be implemented in future.

Added new param "Queues" to the
virtio config file for VirtioUser
bdevs. VirtioPci will use the
max available queues num -
negotiated during QEMU startup.

9f12ec9d32 lvol: remove lvol from lvol_store->lvols list once in lvol destroy
spdk_lvol_destroy() and spdk_lvol_close() behave very similar to
each other. With exception that spdk_lvol_destroy() deletes blob,
after closing the blob.

The order of calls in spdk_lvol_destroy() case:
- spdk_lvo_destroy() calls spdk_bs_md_close_blob()
- _spdk_lvol_delete_blob_cb is callback from closing the blob,
which calls spdk_bs_md_delete_blob()
- _spdk_lvol_close_blob_cb is callback from deleting the blob

The order of calls in spdk_lvol_close() case:
- spdk_lvo_close() calls spdk_bs_md_close_blob()
- _spdk_lvol_close_blob_cb is callback from closing the blob

Lvol was removed from lvol store lvol list in two cases,
spdk_lvol_destroy() and _spdk_lvol_close_blob_cb().
This caused lvol to be removed twice from the list in
lvol destroy case.

This change makes it so it is more clear, that lvol is removed
from lvol store lvol list in both cases and just once.

Every descriptor may now contain

This increases the maximum number
of concurrent IO in a virtqueue
from about (vq->size / 3) to
(vq->size * SPDK_VHOST_IOVS_MAX).

Knowing that SPDK_VHOST_IOVS_MAX
is 128, and assuming that vq->size
is 128 (current hardcoded limit
for QEMU), this gives us over 16k
concurrent possible iovectors
on the fly

6368d6c0f5 nvme: add new spdk_nvme_connect() API to directly attach the ctrlr
With this new API, callers can attach one specific ctrlr identified by
the transport ID directly along with optional ctrlr opts. If connecting
to multiple controllers, it is still suggested to use spdk_nvme_probe()
and filter the requested controllers with the probe callback.

Two primary use cases:
1) connecting to the NVMe-oF discovery controller
2) more straightforward way to connect a specific controller (avoiding
the probe callback)

A typical usage of this API with specific ctrlr_opts:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
   user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))

dc2fb2ed39 nvme: add a public API to rename spdk_nvme_ctrlr_opts_set_defaults
This change is relating to add a new public API spdk_nvme_connect() under
include/spdk/nvme.h. This new spdk_nvme_connect() API will connect the user
specified trid and have a user optional ctlr opts. Rename this API and make
it as public.

A typical usage of this API as following:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
   user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))

356a9bc7d3 bdev_virtio: support UNMAP requests > 4GB
With current SPDK_BDEV_LARGE_BUF_MAX_SIZE
set to 65536, we can allocate at most
4095 16-byte SCSI UNMAP block descriptors.
A single descriptor can UNMAP up to 4GB.
That gives us a hard limit of ~16 terabytes
of data that can be unmmapped by a single
request.

The same limit is also enforced by the
SCSI standard, as the entire UNMAP request
length must be smaller than 65536.

ae19c072e8 vhost: don't abort on event timeout
A single timeout error message is printed on the
screen already, so the user knows about the
timeout. Instead of aborting the app here, wait
endlessly for the event to complete. User
can kill the app any time if he wants to.
