eef6af95d1 vhost_blk: separate out generic virtio_blk request processing
This patch adds process_virtio_blk_request() that will be called
by virtio_blk transports to process incoming requests.

Meanwhile vhost_user_blk_request_finish() will be replaced with
a callback to the virtio_blk transport to notify of the result.

blk_request_finish() should only be called as direct result of
process_virtio_blk_request(), usually from it.
Some error paths now call vhost_user_blk_request_finish() directly,
if vhost_user_process_blk_request() was not called yet.

8c609f29bc lib/vhost_blk: split up vhost_blk task
struct spdk_vhost_blk_task shall contain only fields
that are relevant to the generic virtio blk layer.
Moved to vhost_internal.h header to allow for broader

In contrast to spdk_vhost_user_blk_task that is

57e6a387c2 lib/vhost: remove vhost_user fields from I/O processing logs
Later in the series, the spdk_vhost_blk_task will not contain
vhost_user specific fields. As such the generic part of processing
I/O will not be able to refer to those.

References to req_idx are replaced with pointer to the task,
meanwhile bvsession reference when queueing I/O is removed.

Note that vhost_user fields are accessible in the final callback
for the I/O, and will be printed. See blk_request_finish().

a8757f6081 lib/vhost: cache vdev and io channel for bdev io wait
Previously the blk_request_queue_io() and blk_request_resubmit()
relied on vdev and channel contained in task or bvsession structures.

In an effor to make the I/O processing for virtio blk not reliant
on vhost_user, this patch caches the vbdev and io channel submited
in process_blk_request().

Later in the series, vhost_user structures will be separated out from
the spdk_vhost_blk_task.

c29112b1d7 lib/vhost: accept generic vhost arugments in process_blk_request()
process_blk_request() accepted spdk_vhost_blk_session argument
which is specific for vhost_user. In preparation to making
this function usable outside of vhost_user, replace this field
with struct spdk_io_channel and spdk_vhost_dev.

For this purpose vhost_user_process_blk_request() was created to
translate from spdk_vhost_blk_task to the generic arguments.

to_blk_dev() was moved further up so it can be more commonly used
throughout the file.

eb15d158d4 vhost: Add VIRTIO_F_ANY_LAYOUT feature for vhost
In the qemu virtualization environment, when the virtio driver of the
windows image is upgraded to virtio-win 0.1.185, and virtio uses
legacy mode. In the negotiation stage of vhost, qemu's host_features
will enable VIRTIO_F_ANY_LAYOUT, and guest_features will also enable
this feature, because qemu's feature is a superset, so the feature
will be passed to the spdk side through the set feature process,
which leads to "VHOST_CONFIG: Processing VHOST_USER_SET_FEATURES
failed. VHOST_CONFIG: vhost message handling failed.", so we enable
this bit for spdk vhost.

pending_async_op_num is specific to vhost_user.
To prepare for virtio_blk transport abstraction,
checking for the pending operations is moved to vhost_user

Ideally the vhost_user_dev_unregister() should be the only
function that checks this field, but due to
order of calls in vhost_scsi it needs to remain there separetly.
This should not pose any issue, as vhost_scsi is still dependent
directly on vhost_user.

047c067c05 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 22.05
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

between vhost.c and virtio abstraction.

Otherwise multiple callbacks would be needed during vhost fini.
Ex. spdk_vhost_fini -> vhost_user_fini to stop the sessions ->
-> back to spdk_vhost_fini to remove vhost devices ->
-> vhost_user_fini to destroy the g_dpdk_sem

g_dpdk_sem will only be used from rte_vhost_user.c.
Until all references are moved, it is placed in vhost_internal.

26dfb9a9fa lib/vhost: remove zeroing g_vhost_core_mask on vhost_fini
There is no need to zero out the g_vhost_core_mask on vhost_fini.

Removing it will help later in the series when splitting vhost fini
between vhost.c and virtio abstraction.

g_vhost_core_mask will only be used in vhost.c and any cpu_mask
shall be passed to virtio abstraction after going through
vhost_parse_core_mask. There is no need to make the
g_vhost_core_mask accessible for virtio transports.

Renamed with vhost_user_* prefix to match the file.

Since the rte_vhost functions are still called directly from

7b847784d2 lib/vhost: rename rte_vhost_compat to rte_vhost_user
For some time already the DPDK rte_vhost interface was
accomodating for other types of devices than virtio-net.
rte_vhost_compat.c file contained the use of DPDK rte_vhost,
rather than workarounds. To make that clear it is now renamed
to rte_vhost_user.c.

This patch is first in series that reworks vhost library
with two goals in mind:

1) Refactor vhost and vhost-blk to no longer depend on rte_vhost.
All references to that API will be moved to rte_vhost_user.c.

2) Add a transport abstraction for virtio-blk devices.
vhost-blk will now be able to expose virtio-blk using multiple
implementations of the interface.
First one will be vhost_user that depends on DPDK rte_vhost library.

Caller could match a vhost controller by controller name (socket filename)
or by full path to the socket.
This function is used by vhost RPC too.

The functionality of matching by full path was not documented,
nor matches what is presented in spdk_vhost_dev_get_name()

This patch removes this functionality as part of series

1f9c7a74bc vhost: stop started session in session_shutdown
DPDK vhost will call `new_device` when the VRINGs are
queue paired(virtio-net) or all the VRINGs are started.
However, for virtio-blk/scsi, SeaBIOS will only use one
VRING queue, DPDK added a workaround patch to add
`pre_msg_handle` and `post_msg_handle` callbacks to let
devices other than virtio-net to process such scenarios.

In SPDK, we will start the device when there is one valid
VRING, so there is a case that SPDK and DPDK have different
state for one device.  For a virtio-scsi device, SeaBIOS will
only start the request queue, and in the BIOS stage, SPDK will
start the device but DPDK doesn't think so.  If users killed
SPDK vhost target at the moment, in `session_shutdown`, SPDK
will expect DPDK to call `destroy_device` to do the cleanup,
but DPDK won't do that as it thinks the device isn't started.

Here in `session_shutdown`, SPDK will do this first, it's OK
that DPDK will call another `destroy_device` for devices that
have the same state both in SPDK and DPDK.

Fix issue #2228.

e4070ee0e0 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

ce9efeda3a lib/vhost: set g_vhost_core_mask to all cores rather than threads
spdk_vhost_init() relies on having a thread on each reactor.
Every vhost controller could be created on the same core and
even passing --cpumask when creating would not affect it.

This has happened before, see patch (7cc83b62).

This patch modifies the g_vhost_core_mask to match the actual
cores in use.

b74363bcdf lib/vhost: force cpumask to be subset of application's CPU mask
Documentation for vhost target states that CPU mask must be a subset
of application CPU mask. This wasn't enforced right now and allowed
the cpumask on controller creation so long as at least single
CPU core overlapped with application's CPU mask.

This might have been misleading and covered up user configuration errors.

the github issue link: https://github.com/spdk/spdk/issues/1738
After investigation, we found as below:
The qemu set to VHOST_USER_SET_MEM_TABLE then call vhost_user_set_mem_table(dpdk version spdk-20.11)->mmap(without MAP_POPULATE)
the mmap will only return the virtual address not map the virtual address to the physical address actually.
after call vtophys_notify->vtophys_get_paddr_pagemap, we will get a wrong physical(the virtual address we not access)

So this patch is to set MAP_POPULATE during we use SPDK + UIO.

so the backend may choose to ignore this flag, because WRITE ZEROES
with this flag isn't mandatory.

The spdk api entry is `spdk_bdev_notify_blockcnt_change`.
Any bdev if used as vhost-blk backend may need to implement
a rpc that calls this function.

2187424ab2 lib/vhost: remove dependency on lib/event
In current implementation, lib/vhost assumes that it always runs
together with lib/event, and would call lib/event's functions in
vhost.c. This is not necessary and make program unable to
create/destroy vhost module without init/fini the whole spdk env. It
would cause problems when program runs with vhost and other spdk
components together.

In this patch, we remove the dependency of lib/vhost on lib/event by
adding a global vairable g_vhost_core_mask so that it could handle
core mask by itself.

bcc28e05d1 vhost_blk: speed up the vhost device boot
When starting qemu with vhost-user-blk multiqueue(set num-queues to
more than 1), the vhost device will be started/stopped many times
(related to the queue num), as the vhost-user backend doesn't know the
exact number of queues used for this device.
The target have to stop and start the device once got a valid IO queue.

When stoping and starting the vhost device, the backend bdev io device
will be deleted and created repeatly.

If the backend bdev is a distribution system, the cost is large as the
network RTT.

In this patch, add a dummy_io_channel to hold a reference to the io
device, so that the io device will not be deleted.

e9aec6746a lib/thread: thread_poll() polls until the exiting thread is exited
Extract _spdk_thread_exit() from spdk_thread_exit() and
_spdk_thread_poll() calls _spdk_thread_exit() if the thread is in
the exiting state. spdk_thread_exit() changes to move the state to
the exiting state. The spdk_thread_poll() loop will end after the
thread moves to the exited state because the caller of
spdk_thread_poll() will check if the thread is in the exited state,
and break the loop if true.

If the user does not call spdk_thread_exit() explicitly, the reactor
has to terminate all existing threads at its shutdown. In this case,
multiple threads may have some dependency to release I/O channels or
unregister pollers. So the reactor has the large two loops, the first
loop calls spdk_thread_exit() on all threads, the second loop calls
spdk_thread_destroy() if exited or spdk_thread_poll() otherwise for
each thread until all threads are destroyed.

Besides, change the return value of spdk_thread_exit() to return
always 0. Keep it for ABI compatibility. Change ERRLOG to INFOLOG
for _spdk_thread_exit() because it is called repeatedly now. Remove
the check of I/O reference count from _spdk_thread_exit() because
_free_thread() cannot free I/O channel. Refine the unit test
accordingly.

Fixes issue #1288.
