d1db020954 nvme: add a csi parameter to nvme_ctrlr_cmd_identify()
With the introduction of namespace types, the identify command has
gained an additional parameter: Command Set Identifier (CSI).

This parameter is similar to the existing parameters NSID and CNTID,
and is not used by all CNS values.

Most notably, the CSI parameter is not used for the existing CNS
values 00h (ID NS) and 01h (ID CTRL).
There are new CNS values, e.g. 05h (ID IOCS specific NS), and
06h (ID IOCS specific CTRL), which do take the new CSI parameter.

The new CNS values instead return Command Set Specific data structures,
which is basically an additional data structure. Therefore, the CNS
values 00h and 01h are very much still in use.
(Even the NVM Command Set has a Command Set Specific data structure,
even though all fields in that data structure are currently reserved.)

Since the CSI parameter is unused by all the existing calls to
nvme_ctrlr_cmd_identify() (since none of the calls send in a CNS value
that uses CSI), simply send in 0 for all existing calls.
No functional change intended.

726ac67c55 nvme: use the most appropriate is_active() function
There are two different is_active() functions.
spdk_nvme_ctrlr_is_active_ns() which iterates through the active_ns_list,
and spdk_nvme_ns_is_active(), which simply checks the nsdata.
There is an event callback that refreshes active_ns_list when a relevant
events has occured.

In nvme_ns_construct(), nvme_ctrlr_identify_ns() has just been called,
so we know that nsdata is as fresh as possible.

Hence, there is no reason to iterate through a less fresh active_ns_list.
Since we know that the nvme_ctrlr_identify_ns() call was done through the
same controller, we also know that the active/inactive is from the
perspective of the correct controller, so that is not a reason to use the
less efficient is_active() function.

743271d92d nvme: cache the command set identifier
Since the command set identifier might be accessed at several
different states in the nvme state machine, cache it so that
we don't need to loop through the ns id desc list every time.

This is similar to how other identify fields are cached using
nvme_ns_set_identify_data().

None of the identifiers in the desc list (including the new CSI)
can change over the life time of a namespace, so caching them
should be safe.

a7de7dee23 nvme: remove superfluous else statement
If the nvme completion was an error, the function will return,
so there is no reason for an else statement.

In fact, the else statement in nvme_ctrlr_identify_ns_async_done()
differs from the coding style used in other nvme_ctrlr_identify_*
functions, and arguably makes the code harder to read.

792807a444 nvme: fix infinite loop when aborting queued reqs
When we disconnect a qpair, part of the code path is
calling _nvme_qpair_abort_queued_reqs.  This takes
care of aborting any requests that were queued waiting
for slots to open on the submission queue.
It walks the STAILQ one by one and manually completes
them with ABORT status back to the caller.

But if the callback path submits another request, this
request may also get queued to the end of the queued_req
TAILQ.  This can result in an infinite loop.

The solution is to use an STAILQ_SWAP to a local, empty
STAILQ.  Then we ensure we only abort the requests that
were queued when _nvme_qpair_abort_queued_reqs() started
executing.

Fixes issue #1588.

I used the multipath.sh test to reproduce this on my local
system. If it ever dropped into the STAILQ loop in this
function, we would hit the infinite loop.  With this patch,
I confirmed locally that now we safely avoid the infinite
loop and the test passes.

071d80f37b lib/nvmf: Add an internal API nvmf_subsystem_set_ana_state()
Add an internal API nvmf_subsystem_set_ana_state() to change the
ANA state of the subsystem listener whose trid matches.

ANA optimized state, ANA non-optimized state, and ANA inaccessible
state are supported. ANA change state is not used and ANA persistent
loss state is not supported.

After changing the ANA state of the subsystem listener, on each poll
group, controllers, whose the subsystem listener match, send ANA
change notice.

Initiators query ANA log page anyway if they receive ANA change
notification. False positive notification should be avoided but is
acceptable.

To avoid any concurrency conflict, simply compare ctrlr->listener and
the passed listener.

It may be better to execute nvmf_subsystem_set_ana_state() on the
subsystem thread but currently the RPC thread adds and removes a
listener to and from the subsystem, respectively, and the subsystem
has been suspended while executing nvmf_subsystem_set_ana_state().
Hence we keep this as a future enhancement.

In cases where the SPDK nvme driver is being used as a validation/test
vehicle, users may need to allocate a currently unused qid that can be
used for creating queues using the raw interfaces. One example would be
testing N:1 SQ:CQ mappings which are supported by PCIe controllers but
not through the standard SPDK nvme driver APIs.

These new functions fulfill this purpose, and ensure that the allocated
qid will not be used by the SPDK driver for any future queues allocated
through the spdk_nvme_ctrlr_alloc_io_qpair API.

bd16f57472 blob: switch to bit_pool for tracking used_clusters
We still need to be able to explicitly set specific
bits in the cluster array during initialization and
loading (especially recovery), so we use a bit_array
during load, and then convert it to a bit_pool just
before calling the user's cmopletion callback.

This gives a roughly 300% improvement over baseline
on a benchmark which does continuous resize operations.
The benefit is primarily from saving the lowest free
bit rather than having to always start at bit 0.  We
may be able to further improve this by saving extents
in the bit pool as well, although after this patch,
the benchmark shows other hot spots different from the
bit search.

0d2a5bbe17 util: add spdk_bit_pool
spdk_bit_pool is a wrapper around spdk_bit_array with the
intentions of providing much better performance for allocating
from a fragmented bit array.  The cost of searching a large bit
array for a cleared bit can become expensive so the spdk_bit_pool
will provide an ability to track extents of recently cleared
bits.

This initial commit does not adding the tracking yet - it is strictly
a wrapper around spdk_bit_array with enough functionality to replace
the use of spdk_bit_pool in SPDK blobstore with equivalent performance.
This will allow us to switch blobstore to use this minimal
wrapper first, and then iteratively improve spdk_bit_pool to provide
the better performance.

835fbef712 blob: simplify bs_allocate_cluster
Have it both find and set the lowest available cluster
bit index.

This will temporarily hurt the performance for cluster
allocation, since it will always search starting at
bit index 0.  But upcoming changes in this patch set
will fix that again by using a new spdk_bit_pool object
that will do allocations much more efficiently than the
current implementation here.

ded02d0929 blob: batch used_cluster_mutex operations
Currently if we create a blob of 128 clusters, we
lock/unlock the used_cluster_mutex 128 times - once
for each cluster.  Same when those clusters are released
when the blob is deleted.  Batching these lock/unlock
operations is very easy and gives a noticeable
efficiency improvement.

My local benchmark (1GiB ramdisk, 4KB cluster size,
128 clusters/blob) creates enough blobs to fill the
blobstore and then continuously deletes and recreates
them.  Performance increases 20% on that benchmark
with this patch.

ANA state is per listener and per subsystem, and is stored in

have ANA states.

To change ANA state, we will provide a RPC to change ANA state of

To query ANA state, it will be convenient to get ANA states of all
listeners of one selected subsystem.

c8c73af940 lib/blob: add clearing extents to persist path
This looks like a major omission on persist path.
Especially visible for cases where blobstore was not
reloaded between blob creations/deletion.

Added writing out zeroes to md_pages that contained
truncated extents (resized down).
After zeroes are writen out, md_pages for those extents
are released. In case of blob deletion, extents are
resized down to 0 so all extent pages are released.

903fdb752b nvmf/transport: Use mempool_get_bulk to feel pg cache
When we try to evenly divide transport buffers between poll grouos,
e.g. when we run spdk_tgt on 8 cores, set num_shared_buffers=32768
and pg buf_cache_size=4096, the last pg can't retrieve enough
buffers to fill cache. In my case if only got 4040 buffers out of
4096. Missing 56 buffers were cached by previous poll groups.
That occurred due to mempool has per lcore cache of 512 elements
and when it becomes empty, the cache is refilled. It seems that
each poll group cached extra 8 buffers.
The issue doesn't occur when we use mempool_get_bulk.
