29c0e0dc3e thread: add spdk_poller_get_id
Issue: spdk_top tracked pollers by the poller name string and the
thread_id they are running on. This shows incorrect stats when
multiple pollers exist on the same thread with the same name.
Solution: Added a unique poller id for each poller on a thread and
to allow spdk_top to track pollers by thread_id and poller_id.

9072c4ad0d accel: create SW Engine Channel if HW Engine not supports
Currently either HW Engine Channel or SW Engine Channel will be used.

In the case that HW Engine Channel is used while does not support related
operations like IOAT for CRC, it will shift back to the SW Engine's handle.

So that this is an issue that it still refers to the HW Engine Channel
while needs SW Eninge Channel to handle.

This patch introduces the SW Eninge Channel and always initializes there
in case that HW Engine does not support some operations.

Related UT also added to simulate the case the IOAT does not support CRC
and then SW Eninge needs to properly handle it.

1cfdbd429f include/mock.h: prevent expension of syscall name
If a platform defines a syscall using a macro (e.g. #define open _open)
then wrapping it fails because DEFINE_RETURN_MOCK and MOCK_GET
will use the definition to name the ut_ variables, but DEFINE_WRAPPER
will use the original name. This result in an undefined reference when
linking.

Prevent macro expansion of the syscall name by avoiding nested macro
calls in DEFINE_WRAPPER. Include the contents of DEFINE_RETURN_MOCK
and MOCK_GET directly in DEFINE_WRAPPER.

a86e40f320 scheduler: create public API and subsystem for scheduler/governor
This patch moves schedueler and governor related API from
the internal event.h to public scheduler.h.

With this it is possible to create subsystem responsible
for handling the schedulers.
Three schedulers and a governor were moved to scheduler modules
from event framework.

This will allow next patch to add JSON RPC configuration
to the whole subsystem.
Along with easier addition of other schedulers.

Removed debug logs from gscheduler, as they serve little purpose.

df42f3582b lib/accel: eliminate need for caller to schedule completions
Previously the accel_perf tool would look at whether it had HW
or SW commands to know whether to execute the callback right away
or schdule to avoid blowing the stack (SW calls are sync).

Moved this to the SW module (part of the accel engine) so the
caller doesn't have to worry about.  Allowed for a few simplifcations
in the tool as well.

Also, instead of using send_msg to call the completion we add it to
a list in the sw module that a new poller uses to perform the
completions as this is more efficient the sending a message to the
same thread.

d6c4f8cf6b lib/event: refactor _spdk_scheduler_set()
By default g_scheduler is now NULL. It can be set
either by event framework or RPC.
To keep RPC consistent, the 'static' scheduler was kept.

All access to the g_scheduler is done via _spdk_scheduler_get().
Access to its members is done to balance, get name for RPC and
through _spdk_scheduler_set(). All of them happen on scheduling
reactor and don't pose race condition when changing scheduler.
There is no need to delay init/deinit of scheduler via g_new_scheduler.
This variable was removed and all that happens in _spdk_scheduler_set().

To unset and deinitialize current scheduler,
_spdk_scheduler_set(NULL) has to be called.
This results in moving scheduler deinitalization to that
call too.

Every spdk_scheduler callback is now mandatory.

cff96883fc lib/event: remove is_scheduling flag from reactor
There is only one g_scheduling_reactor (main core), the is_scheduling
flag for it is used to block starting new gather_metrics before
previous one is finished.

Meanwhile is_scheduling flag on other reactors was used to block
destroying lw_threads while scheduling happens. It was only needed
because scheduler interacted with the same lw_thread pointers as
each reactor. Previous patch removed this dependency, instead
spdk_thread ids is used. If an spdk_thread is destroyed,
while scheduling _threads_reschedule_thread() handles it.

It is no longer required to block destruction of lw_threads
based on this flag.

Instead of using the main core reactor flag, a g_scheduling_in_progress
is introduced.

Removed _spdk_get_scheduling_reactor() and instead shared the value
of g_scheduling_in_progress between reactor.c and app.c.

b74b6133fa lib/event: remove scheduler dependency on lw_thread
Removing dependency on schedulers to directly modify
lw_thread field structures will help making schedulers
truly plugable.

Instead of using lw_thread, new structure is created
that holds copy of stats and refer to the thread by
spdk_thread id.

As an added benefit of not changing lw_thread directly,
we won't run into issue of balancing function changing it
while other reactor removes and frees it.

In the future an API will be added for scheduler to call
in order to move the thread directly. Rather than for
event framework to rely on modified core_info/thread_info
structure.

e0d448e7f6 lib/event: remove snapshot_stats
spdk_thread keeps track of tsc from its whole lifetime,
those can be requested with spdk_thread_get_stats() at any time.

spdk_lw_thread uses stats from above and keeps track of two points in time:
- current_stats reflecting stats at the time of gather_metrics stage
- last_stats reflecting stats from previous gather_metrics stage

1)
Before this patch current_stats were duplicated in snapshot_stats.
There is no need for that so now they are removed.

2)
Removed _spdk_lw_thread_get_current_stats() since it would be copying
current_stats to current_stats, thus not perform any action.

5a1c74bfa4 usdt: add User Space DTrace support to SPDK
For now, we will keep this disabled by default,
enable with --with-usdt option to the configure
script.  Long-term we will want to enable this by
default, and only disable via configure.

Modules can include spdk_internal/usdt.h and add
probes such as:

SPDK_DTRACE_PROBE2(probe_name, ptr, val);

When USDT is enabled, these will translate to
DTRACE_PROBE2(spdk, probe_name, ptr, val).  When
USDT is disabled, these will translate to nothing.

Later patches will add some probe points to the
nvmf target, some bpftrace scripts, and instructions
for how to successfully capture data with these
probe points and scripts.

1aec9334d9 thread: Change direct accesses to poller outside lib/thread to helper functions
Most accesses to the struct spdk_poller outside lib/thread have been
done via functions but a few direct accesses remain.

Change these to indirect accesses by addinng a few helper functions
as SPDK internal APIs.

Add spdk_poller_get_name() to get the name of the poller.

Remove spdk_poller_state_str() and add spdk_poller_get_state_str().
Exposing enum spdk_poller_state outside lib/thread is not really
necessary.

This removal requires us to update major SO version.

Add spdk_poller_get_period_ticks() to get the period ticks of the
poller.

Add struct spdk_poller_stats and spdk_poller_get_stats() to get
the stats of the poller.

The next patch will move the definition of struct spdk_poller and
enum spdk_poller_state from include/spdk_internal/thread.h to
lib/thread/thread.c.

cd83ea4a6d thread: Add SPDK internal APIs spdk_thread_get_first/next_active/timed/paused_poller()
The following patches will introduce red black tree to manage
timed pollers efficiently but it will be based on macros available only
in lib/thread/thread.c. Hence then it will be difficult to expose the
internal of timed pollers tree outside the file. On the other hand,
we do not want to include JSON into the file.

Hence add a few SPDK internal APIs to iterate pollers list transparently.

For spdk_thread_get_next_active/timed/pause_poller(), we omit the parameter
thread and get it internally from poller->thread even if the names include
the term "thread". This will be slightly cleaner.

To route all connections of poll group through single queue a unique
placement id is chosen as group_placement_id and each socket of poll
group is marked with group_placment_id using getsockopt(SO_MARK) option.

The driver could use so_mark value of skb to determine the queue to use.

53429c7f44 thread: distinguish intr enabled and set
As a start of combining interrupt ability into poller,
it aims to get spdk_thread & spdk_poller runnable between
poll mode and interrupt mode with dynamic switching.

spdk_interrupt_mode_is_enabled() indicate whether interrupt
mode is enabled and dynamic switching is permitted. So
spdk_interrupt_mode_is_enabled==true leads to set up
interrupt mode related resources;
in_interrupt flag indicates whether one spdk_thread now
is running in intr mode.
It is possible that spdk_interrupt_mode_is_enabled==true
but in_interrupt==false. this means spdk_thread & spdk_poller
switched to poll mode from interrupt mode due to heavy
workload coming.

To align with spdk_reactor, use "in_interrupt" to
indicate whether one spdk_thread now runs in intr.

1eae58ff6d rdma: Add statistics per qpair

for mlx5_dv per each ibv_wr_complete call.

Recv: the doorbell updates statistics for both
providers are updated when either ibv_post_recv
or ibv_post_srq_recv functions are called.

Each qpair on initialization accepts an optional
pointer to shared statistics (nvmf/nvme poll groups).
If the pointer to statistics is not provided then
qpair allocates its own structure. That is done
to support cases when NVME RDMA initiator doesn't
use poll groups, so we can avoid checks that qpair
has statistics in IO path

d5cd0b13b6 sock: Fix the "sock remove assert bug" in spdk_sock_group_remove_sock
The statement causes this issue is:

assert(group_impl->num_removed_socks < MAX_EVENTS_PER_POLL);

The call trace is:

The previous solution is:
commitid with: e71e81b631

But with this solution, it will always add the sock
into the removed_socks list even if it is not under polling
context by sock_group_impl_poll_count. So it will exceed the size of
removed_socks array if sock_group_impl_poll_count function will not be
called. And we should not use a large array, because it is just a workaround,
it just hides the bug.

So our current solution is:

1 Remove the code in sock layer, i.e., rollback the commit
 e71e81b631. This patch is
not the right fix. The sock->cb_fn's NULL pointer case is
caused by the cb_fn of write operation (if the
spdk_sock_group_remove_sock is inside the cb_fn). And it is not
caused by the epoll related cache issue described in commit
"e7181.." commit, but caused by the following situation:

(1)The socket's cb_fn is set to NULL which is caused by
spdk_sock_group_remove_sock by the socket itself
inside a call back function from a write operation.

(2) And the socket is already in the pending_recv list. It is
not caused by the epoll event issue, e.g., socket A changes Socket B's
cb_fn. By the way, A socket A should never remove a socket B from a polling group.
If it really does it, it should use spdk_thread_sendmsg to make sure
it happens in the next round.

2 Add the code check in each posix, uring implementation module.
If sock->cb_fn is NULL, we will not return the socket to the active socks list.
And this is enough to address the issue.

e7f6ff2db6 Fix incorrect implementation of HPDA/CPDA in NVMe/TCP target code.

incorrect. The HPDA/CPDA actually specify where the payload data
should start such that the starting location is a multiple of HPDA
(for C2H PDU) or CPDA (for H2C PDU or CapsuleCmd PDU).

The other issue fixed is that the current implementation calculates
padding only when header digest is enabled. This is also incorrect.

6fdc71ec18 lib/thread: Defer exiting thread if thread is unregistering io_device
Current SPDK thread library has a issue which occurs if there is
a race between exiting thread and unregistering io_device.

For example, there are two threads. Thread 1 registers a device
and thread 2 gets a channel of the device. Then if thread 1 starts
exiting and unregisters the device, and then thread 2 puts the channel,
thread 2 sends a message to thread 1 to complete releasing the device,
thread 1 already moved exited. Hence thread 2 failed to send the
message.

This patch fixes the race issue. The code is verified by adding
a unit test case.

In detail, add a count, unregistering_dev, to struct spdk_thread,
increment it if a callback is specified to spdk_io_device_unregister(),
and then decrement it in _finish_unregister(), and thread_exit()
checks if it is zero.

The contents of struct spdk_thread is changed but it is not public
data structure, and hence suppress it for ABI testing.

parameter in_capsule_data_size is applied to all qpair types -
admin and IO. Also we allocate resources when we get a connection
request, so we don't know qpair type at this moment.
Create a list of buffer in TCP poll group to support ICD up
to 8192 bytes when configuration ICD is less than this value.
The number of elements in this pool is hardcoded, it is planned
to add a new configuration parameter later.

17bb748a60 accel: Move non-engine specific batch to the accel_fw layer
The new design:

* Supports a generic batching capability in the accel_fw layer
that keeps track of hw accelerated vs sw commands based on
the capabilities of the engine and processes sw commands in the
generic layer while sending a list of commands (not a batch)
to the engines for processing.

* Batch completions are managed via the generic layer, when using
the accel_fw the engines only process commands. With DSA however,
if a list of commands is sent down it will use the DSA public
API to create and send batches but will rely on the generic layer
to complete the batch task itself. When using DSA directly, batching
works as usual (DSA handles batch completion).

* The engine function tables were greatly simplified by replacing
all of the individual entries (copy, fill, crc32c, etc) with one
`submit_tasks` function that is used to both send lists of tasks
for batches or just one task for single shot API.

* Internally batching is now used to re-submit tasks that were queued
for flow control reasons.
