f5ba8a5ef5 nvme: add NVME_CTRLR_STATE_READ_CAP
Read CAP (Capabilities) register as part of controller
initialization instead of controller construction.

For now, still read CAP in the pcie and vfio-user
controller construction, since they need the
drstd (doorbell stride) to construct the admin
queue.

df01076f70 nvme: add NVME_CTRLR_STATE_READ_VS
Read VS (Version) register as part of controller
initialization instead of controller construction.

This prepares for upcoming changes to make
controller attach fully asynchronous.  Since reading
fabrics registers is an asynchronous operation, it
will be easier to read the VS register as part of
controller initialization which operates as an
asynchronous state machine.

a12cf26cdd nvme: add NVME_CTRLR_STATE_CHECK_EN
We're going to be adding some new states (READ_CAP
and READ_VS) in future patches, that we want to
come before the current "INIT" state.

So we will simply make "INIT" have the same
value as this new NVME_CTRLR_STATE_CHECK_EN state
for now.  That means existing code won't have to
change later once we add new states that come
before CHECK_EN.

aebbce2520 nvme: Refactor active namespace list retrieval
Previous implementation allocated memory just once at the beginning of
active NS list retrieval procedure. It allocated memory for maximum
possible number of active namespaces, i.e. 'cdata.nn'.

This patch changes allocation logic. One page is allocated at the
beginning. If more is needed, reallocation is done with one more
page.

This patch also removes SPDK_MALLOC_DMA flag from allocation since we
don't do RDMA directly into this buffer.

remap VM's NVMe command data buffer to local virtual address,
and for command using PRP, there maybe multiple pages, when
parsing the PRP list to local IOVs, we need a parameter to check
that the maximum number of vectors can't exceed the IOVs, this API
can't meet the requirement, while here, we add a new API `spdk_nvme_map_cmd`
and with a new parameter `max_iovcnt` to fix this case, and it can
also cover the command using SGL in the coming patches.

2910ba6c53 nvme: simplify controller statemachine
For the following nvme controller statemachine states:
NVME_CTRLR_STATE_IDENTIFY_NS
NVME_CTRLR_STATE_IDENTIFY_ID_DESCS
NVME_CTRLR_STATE_IDENTIFY_NS_IOCS_SPECIFIC

The statemachine can either:
- Jump to succeeding state
- If active ns list is empty, jump directly to NVME_CTRLR_STATE_CONFIGURE_AER
- In the unlikely case if NVMe completion error, jump to NVME_CTRLR_STATE_ERROR

Simply this such that we either:
- Jump to succeeding state
- In the unlikely case if NVMe completion error, jump to NVME_CTRLR_STATE_ERROR

This will help to reduce the complexity of the nvme controller statemachine,
especially considering that there are new additional states
(NVME_CTRLR_STATE_IDENTIFY_NS_DIRECTIVE and
NVME_CTRLR_STATE_CONFIGURE_NS_STREAMS) currently on review that would continue
with the bad habit of having three possible jump states instead of just two.

if spdk_nvme_ctrlr_reset() failed, nvme_ctrlr_fail() is called, and
then if spdk_nvme_ctrlr_process_admin_completions() failed,
nvme_ctrlr_fail() is called.

We don't know which one comes first but nvme_ctrlr_fail() should do
nothing if the ctrlr is already failed.

Hence we should avoid setting ctrlr->is_failed and calling
nvme_transport_ctrlr_disconnect_qpair() twice.

However we should set ctrlr->is_removed if the parameter hot_remove is true.

We do these changes in this patch.

3c2190c214 nvme: capture ticks for timeout before checking state
In some extreme use cases, an SPDK process could get
swapped out for a long period of time just after
we checked the state but before we called spdk_get_ticks().
So now we will only timeout if the timer expired before
we checked the state *and* the state did not advance.

It's possible we could just move the timeout check
to before the ctrlr->state switch, but I was
hesitant to change the flow for this case.

Fixes issue #1720.

17afd268df nvme: call correct remove_cb when device is removed
When a device is removed, we should use the remove_cb
that was specified when the device was originally probed
and attached, if one was set.

Also add a new spdk_nvme_ctrlr_set_remove_cb API.  This
can be used for cases where a different remove_ctx is
desired than was specified for the probe call.  This
also enables setting a remove_cb when using connect APIs
which do not have a way currently to provide a remove_cb.

This also requires fixing the bdev nvme module, which
was depending on the previously errant behavior.

Fixes issue #1715.

d7345e08ae nvme: group NVME_CTRLR_STATE_WAIT_FOR_* states together
While I assume that the initial thought of having the
NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it is
waiting for, was to make it clear for the reader in which order the
states will be executed.
However, it feels silly to have the same code copy pasted everywhere.

Someone who needs to add a new state will still need to edit
nvme_ctrlr_state_string() and enum nvme_ctrlr_state, which still defines
the NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it
is waiting for.

In one way, moving the NVME_CTRLR_STATE_WAIT_FOR_* states to the end of
nvme_ctrlr_process_init(), when reading nvme_ctrlr_process_init(), it is
actually easier to see the ordering of the states which actually do
something of significance.

257fcb7352 lib/nvme: Make nvme_ctrlr_shutdown() asynchronous
This patch is the first of the patch series to make spdk_nvme_detach()
asynchronous.

We have lengthy shutdown notification, i.e., we have to wait a long time
until shutdown processing is completed, in some SSDs. If the running system
has many such SSDs, we see large intolerable delay.

SPDK provides a controller option, no_shn_notification as a workaround.
We can use the workaround if the use case of the detach is to switch to
the next application without system reboot. However, we cannot use the
workaround if we want to do system reboot after detach.

To mitigate such lengthy shutdown notification, we need to parallelize
detachment among SSDs.

Hence the patch series will introduce an asynchronous detach API and
will use the API to parallelize detachment.

This patch adds the following changes.

Introduce a context structure and separate nvme_ctrlr_shutdown()
itno nvme_ctrlr_shutdown_async() and nvme_ctrlr_shutdown_poll_async()
using the context structure.

Name the context structure as nvme_ctrlr_detach_ctx because it will be
used only in internal APIs. The upcoming public APIs will support
multiple detachment and will have the contest structure named as
spdk_nvme_detach_ctx.

Use TSC instead of counter because polling interval will be controlled
by the caller.

Use the convenient macro, SPDK_CEIL_DIV(), to round off the time
value in milliseconds.

198a3ad2fd nvme: if no command set is requested, use the most reasonable default
Since namespace types were introduced in NVMe, the CC.CSS register
has a new value (SPDK_NVME_CC_CSS_IOCS) which indicates that all
supported command sets should be selected/enabled. This possibly
includes command sets other than NVM and ADMIN only.

Therefore, if a SPDK application wants enable all the command sets
that the controller supports, it has to explicitly set
opts->command_set to SPDK_NVME_CC_CSS_IOCS.

To avoid possibly a lot of SPDK applications having to set this
parameter, check if the user requested a command set explicitly,
if not, make SPDK automatically use the most reasonable default,
based on the supported bits set by the controller.
The most common case is that you want to enable (all) the command
sets that the controller supports.

A user will still be able to restrict the controller to only use
the NVM command set (or ADMIN only), by setting opts->command_set
to a specific value.

Since the current default command set value specified by
spdk_nvme_ctrlr_get_default_ctrlr_opts() is SPDK_NVME_CC_CSS_NVM,
which is defined as 0, we cannot know if the user specified a
command set explicitly or not.
To solve this, change the default command set value specified by
spdk_nvme_ctrlr_get_default_ctrlr_opts() to CHAR_BIT (0x8), which
is larger than the largest value that can be set in CS.CSS (which
is only 3 bits wide, thus 0x7).

c4d1b7d57a nvme: add new state to get Identify IOCS Specific Namespace data structs
Add a new state in the SPDK NVMe state machine in order to fetch
I/O Command Set Specific Namespace data structures.

Right now there is only support for the Zoned Namespace Command Set
Specific Identify Namespace data structure.

The NVM Command Set Specific Identify Namespace data structure is
all zeroes right now, reserved for future use.
The Key Value Command Set Identify Namespace data structure is not
all zeroes, however, adding support for Key Value is outside the
scope of this patch.

The new NVME_CTRLR_STATE_IDENTIFY_NS_IOCS_SPECIFIC state is added
after the NVME_CTRLR_STATE_IDENTIFY_ID_DESCS state. This is because
we need to have fetched the identifiers in the desc list in order
to know which command set a namespace belongs to.

A slightly nicer design might have been to refactor the NVMe state
machine to first fetch the id desc list, then the identify namespace
struct, and finally the identify IOCS specific namespace struct.
However, since this would have required a lot of changes, it didn't
really seem justified.

When creating a controller, allocate a buffer to the controller
and read ANA log page into the buffer.

When receiving ANA change notice, read ANA log page into the buffer
to keep the contents up to date.

The next patch will provide a public API to get the contents of
ANA log page the controller holds.

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.

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.

4e06de69b8 nvme: expose functions to manage queue identifiers
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.

ae6c40a4a5 lib/nvme: fallback to NVM when then given command_set is not supported
When the user requests a non-default command set configuration, via the
probe_cb() supplied to spdk_nvme_probe(), which is not supported, then
the controller initialization will not proceed.

This patch changes that behavior into falling back to the NVM command
set and continue with the controller initialization. It is done by
assigning the NVM command set to opts.command_set such that the user
knows in attach_cb() with which command_set the controller is
configured/enabled.

The fallback is needed since the user does not have access to the
controller capabilities register. The strategy left for the user is thus
to try. However, this is an issue, as the user only has one attempt, as
subsequent calls to spdk_nvme_probe() will not trigger probe_cb() for
the controllers whose initialization did not proceed.

timer value stored in controller opts structure. This value is already
communicated to target in CONNECT command.

Fixes #1328

will be freed by nvme_completion_poll_cb if it contains a

will work with already freed memory.
Fix - allocate nvme_completion_poll_status object using

bad2c8e86c nvme: detach the controller in STUB and flush the admin active requests at last
In the autotest, when calling kill_stub() function, there is error log
like this: "Device 0000:83:00.0 is still attached at shutdown!", so it's
better to detach the controller when exit the stub process.

But after call spdk_nvme_detach() in the stub process, there is another issue:
1. NVMe stub running as the primary process, and it will send 4 AERs.
2. Using NVMe reset tool as the secondary process.

When doing NVMe reset from the secondary process, it will abort all the
outstanding requests, so for the 4 AERs from the primary process, the 4
requests will be added to the active_proc->active_reqs list.

When calling spdk_nvme_detach() to detach a controller, there is a
assertion in the nvme_ctrlr_free_processes() at last to check the
active requests list of this active process data structure.

We can add a check before destructing the controller to poll the
completion queue, so that the active requests list can be flushed.
