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.

012b233426 ut/reactor: implement stub for _spdk_get_app_thread()
Functions that set reactor interrupt mode were not tested
since _spdk_get_app_thread() always returned NULL and
implementation did not verify the RC.

This patch will return a thread from scheduling reactor
as the app thread. Which is not exact, but otherwise
a new app thread would have to be added to each UT.

spdk_reactor_set_interrupt_mode() requires the completion to
be executed on app_thread. Added the poll of that thread
to make sure it gets drained.

Since now the UT actually executes the code path,
additional 4 events will be processed.

66a5b406cb scheduler_dynamic: lower the idle thread limit
Limit of 50% to mark thread as active or idle
didn't allow for multiple active threads to be placed
on single core.

Lowering the limit to 20% will allow that and force
more threads to be actively balanced.

Removing the limit was considered, but that would
cause too much thread moves when a thread with load
in single digits increased briefly. Either
due to actually doing any operation or placement
of other threads on the same core.

68063cd8b6 lib/blob: force md update during decouple parent
Fixes #1933

When decoupling parent the updated parent_id was
not persisted to the blob if it was a snapshot.
Due to having md_ro set to true, blob_set_xattr()
failed.

Later on the incorrect parent_id could cause troubles
like in the github issue, when deleting that snapshot.

This patch adds return code check for blob_set_xattr
and forces md_ro to false during blob md sync.

Since some of code paths are shared between decouple,
inflate and clone operations, the final callback for them
is doing revert of the original md_ro.

After this patch, nbd will no longer receive any requests if
NBD_CMD_DISC is received. But it will handle the  requests
already received.

Previously we called spdk_bdev_abort() for NBD_CMD_DISC and
it will reply to the rest requests in the channel of this bdev.

But there should be no reply to NBD_CMD_DISC. Hence we silently
discards requests after NBD_CMD_DISC.

814cd25882 nvmf: optimize log level for unsupported feature IDs and invalid property offset

PCIe SSD only, such as set/get features with interrupt coalescing
and Interrupt Mask Set/Interrupt Mask Clear registers.  Even the
NVMf library doesn't support that, it is not a fatal error to Host
NVMe driver, so here we use the info log instead of error log for
this case so that to avoid noise logs.

Fix #2036.

e45450d28f thread: spdk_get_io_channel() use i->dev as the search key
In current implementation, io_channel list will be accessed by
spdk_for_each_channel() and spdk_get_io_channel(). We will try to
accelerate spdk_get_io_channel() in the following change "thread: speed
up io_channel lookup by using rbtree" by changing io_channel from list
into RB tree.

To make it cleaner, we prefer to use ch->dev as the key for the
io_channel RB tree instead of ch->dev->io_device. This patch makes
spdk_for_each_channel() use the i->dev to find the expected io_channel.
And the io_device in structure spdk_io_channel_iter is not needed in
spdk_for_each_channel_continue() but we keep it for the compatibility of
spdk_io_channel_iter_get_io_device().

After this patch, spdk_for_each_channel() has to access both io_device
list and io_channel list, and spdk_for_each_channel_continue() still has
to access only io_channel list.

Both io_device list and io_channel list will become RB tree. Hence
performance degradation will be negligible. spdk_for_each_channel() is
not so performance critical than spdk_get_io_channel().

f95bd3b6c7 lib/idxd: change how we complete batch desc
Previously we used a counter of our own to make sure all batch
elements plus the batch itself were done before we freed the batch.
This was due to some observations early on that the batch desc
could complete before the individual elements and a lack of clarity
as to whether this was due to the simulator or the fact that
we poll on completions and could therefore "see" completions in
a different order at that time (we were using bit arrays to poll).

Now we use an ordered (in time) list to poll locations so if we
instead put the elements on the list first and then the batch desc
itself we are assured to always "see" them in order provided the
underlying device meets spec which there's no reason to assume it
does not.

This simplifies things a bit at the same time and still assures
that we call list calbacks in order and then the batch callback
without "special" handling.

a738acd505 examples/accel_perf: use local task element for CRC destination
For all CRC related functions.  Does not need to be DMA'able memory
as DSA returns the CRC to it's completion record and the lib
copies it to this address.  Done for consistency as this element
was added as part of adding the copy+CRC API.

320ab72fb5 util: Add macro SPDK_SIZEOF_MEMBER to get size of a member of a struct
We find a few files to get the size of a member of a struct. How to
do it is a little complex. So add a macro to do it will be helpful
to read the current code and develop new features.

lib/dif had used member_size() internally but Linux use sizeof_member()
as the macro. Besides, SPDK have used upper case letters for similar
macros, SPDK_CONTAINEROF() and SPDK_COUNTOF(). Hence spdk_member_size()
may be good but propose SPDK_SIZEOF_MEMBER() as the macro.

a066f0c3fb nvme: Fix the bug that assumed ANA group descriptor is 8-bytes aligned
This fix is as same as for NVMe bdev module.

If a ANA log page has two or more ANA group descriptors, the second
or later of ANA group descriptors will not be 8-bytes aligned.
Then runtime error would occur as follows:

runtime error: member access within misaligned address 0x612000000074
for type 'const struct spdk_nvme_ana_group_descriptor', which requires
8 byte alignment

nvmf_get_ana_log_page() in lib/nvmf/ctrlr.c creates a ANA log page
data and processes 8 bytes alignment correctly because we got the
same runtime error before. However, lib/nvme had been missed at that
time.

2ed914f8ea idxd: Add the kernel idxd support
This patch is used to add the kernel idxd support.

Without this patch, we can use userspace idxd driver
under accel_engine library (module/accel/idxd/accel_engine).
With this patch, we can also kernel idxd driver under the
accel_engine library.

Our approach is implementing a wrapper library to use IDXD
device by leveraging the kernel DSA driver in SPDK idxd library
(lib/idxd).

Then users can leverage the RPC later to configure how to
use the DSA device by user space driver or kernel driver.

In this patch, our approach is to use the idxd-config library
to export the WQs (Working Queues) exported by the kernel.

870a606960 nvme: map PRP and SGL lists RO

read-only memory, so attempting to map it RW can break things.
