9529803fe0 lib:vhost Add version check when use RTE_VHOST_USER_ASYNC_COPY in 21.01
In dpdk 19.11 version, RTE_VHOST_USER_ASYNC_COPY is not define.
After dpdk 20.08, we can use RTE_VHOST_USER_ASYNC_COPY.
Use version check to avoid this problem.

7741de6b7d vhost/compat: add RTE_VHOST_USER_ASYNC_COPY flag when used IOVA_PA mode
Recently, we discovered that under the SPDK + UIO mode, it is possible that vm may be wrong when doing io.
such as:
[root@VM_6_151_centos ~]# mkfs.xfs /dev/vdc

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.

6bd7bd0da2 vhost: deprecate internal vhost library support
The internal vhost library is used when DPDK's version
is older than 19.05 and the experiemntal vhost nvme
target.

For the CONFIG_INTERNAL_VHOST_LIB option, SPDK doesn't
enable this option by default over one year and CI
doesn't cover it either, so we may remove it with
this release.

As for the vhost-nvme target, since we are developing
a new vfio-user target solution, it's OK for us to remove
it now.

f29d20a21e vhost: add a protocol_features parameter in vdev
Add the protocol_features in vdev. There are two features
would be used in vhost device one is the virtio_features
the other is the vhost-user protocol_features. For different
vhost device, the supported features are different so we can
separate them.
Another reason is that I tested the VHOST_USER_PROTOCOL_F_
INFLIGHT_SHMFD in vhost-scsi with QEMU(version:4.0) and found
that Qemu can not boot up. After investigating found that inflight
flag is negotiated but the Qemu doesn't support this feature
and in DPDK function it is handled as an error and disconnect
with Qemu. It's a bug in DPDK and will fix it.

1dae563373 vhost: move rte_vhost socket creation to rte_vhost_compat.c
rte_vhost_compat.c will now not only handle vhost-user
messages over the unix domain socket, but also setup
that unix domain socket with rte_vhost's APIs.

What was previously called vhost_dev_install_rte_compat_hooks()
is now called vhost_register_unix_socket() and is responsible
for creating the entire unix domain socket.

This enables us to write more advanced unit tests for vhost.
Instead of mocking low-level rte_vhost APIs, we could
now potentially mock vhost_register_unix_socket() and
create vhost devices and sessions without any actual
unix domain sockets involved.

376d893a20 vhost: introduce vsession->started
We used to rely on lcore >= 0 for sessions that are
started (have their pollers running) and in order to
prevent data races, that lcore field had to be set from
the same thread that runs the pollers, directly after
registering/unregistering them. The lcore was always
set to spdk_env_get_current_core(), but we won't be able
to use an equivalent get_current_poll_group() function
after we switch to poll groups. We will have a poll group
object only inside spdk_vhost_session_send_event() that's
called from the DPDK rte_vhost thread.

In order to change the lcore field (or a poll group one)
from spdk_vhost_session_send_event(), we'll need a separate
field to maintain the started/stopped status that's only
going to be modified from the session's thread.

1ecbb6a8da vhost/compat: start polling queues prematurely
rte_vhost requires all queues to be fully initialized
in order to start I/O processing. This behavior is not
compliant with the vhost-user specification and doesn't
work with QEMU 2.12+, which will only initialize 1 I/O
queue for the SeaBIOS boot. Theoretically, we should
start polling each virtqueue individually after
receiving its SET_VRING_KICK message, but rte_vhost is
not designed to poll individual queues. So we use
a workaround to detect when a vhost session could be
potentially at that SeaBIOS stage and we mark it to
start polling as soon as its first virtqueue gets
initialized. This doesn't hurt any non-QEMU vhost slaves
and allows QEMU 2.12+ to boot correctly. SET_FEATURES
could be sent at any time, but QEMU will send it at
least once on SeaBIOS initialization - whenever
powered-up or rebooted.

Vhost sessions are still mostly started/stopped from
within rte_vhost callbacks, but now there's additional
concept of "forced" polling, in which SPDK starts
sessions manually, while rte_vhost still thinks the
sessions are stopped. This can potentially lead to cases
where a session is "started" twice, or gets destroyed
while it's still being polled (by force). Those cases
also need to be handled within this patch.

626ceb20fe vhost/compat: stop session at each SET_VRING_CALL msg
VHOST_USER_SET_VRING_CALL invalidates the previous
file descriptor that SPDK may be using on a different
thread. The new descriptor is stored inside rte_vhost
internals and is queryable with rte_vhost APIs, but
those APIs are too expensive to be called every tick
or every time we need to use that fd. Hence, we will
now stop the entire vhost session before processing
SET_VRING_CALL msg and restart it right after. SPDK
will query the most recent call descriptor on session
start.

We do not necessarily have to stop the device - just
letting the session know that its callfd has changed
would be enough. That's an area for future optimization.

0a6ad9b02e vhost: install external msg handling hooks to rte_vhost
DPDK 19.05+ gives us an ability to pre or post-process
any single vhost-user message. The user can either perform
additional actions upon some generic events, or can
implement handling for brand new message types that
rte_vhost doesn't even know about.

In order to smoothly switch to the upstream rte_vhost
and drop our internal copy, we introduce an SPDK wrapper
function to register SPDK-specific message handlers. For
DPDK 19.05+ this will use the new rte_vhost API to
register those message handlers, and for older DPDKs
this function simply won't do anything - as w assume the
internal rte_copy already contains all the necessary
changes and does not need any "external" hooks.

For now we use the message handlers to stop the vhost
device and wait for any pending DMA ops before letting
rte_vhost to process the SET_MEM_TABLE message and unmap
the current shared memory.
