||||
bdev_io primary buffer. 'spdk_bdev_io_put_aux_buf' frees the allocated auxiliary

buffer.

||||
### blobfs
|
||||
|
||||
Added boolean return value for function spdk_fs_set_cache_size to indicate its operation result.
|
||||
|
||||
Added `blobfs_set_cache_size` RPC method to set cache size for blobstore filesystem.
|
||||
|
||||
### dpdk
|
||||
|
||||
Updated DPDK submodule to DPDK 19.11.
|
||||
|
||||
### env_dpdk
|
||||
|
||||
`spdk_env_dpdk_post_init` now takes a boolean, `legacy_mem`, as an argument.
|
||||
|
||||
A new function, `spdk_env_dpdk_dump_mem_stats`, prints information about the memory consumed by DPDK to a file specified by
|
||||
the user. A new utility, `scripts/dpdk_mem_info.py`, wraps this function and prints the output in an easy to read way.
|
||||
|

### event
|
||||
|
||||
The functions `spdk_reactor_enable_framework_monitor_context_switch()` and
|
||||
`spdk_reactor_framework_monitor_context_switch_enabled()` have been changed to
|
||||
`spdk_framework_enable_context_switch_monitor()` and
|
||||
`spdk_framework_context_switch_monitor_enabled()`, respectively.
|

All NVMe dependencies were removed from ftl library.

`spdk_ftl_punit_range` and `ftl_module_init_opts` structures were removed.

### scsi
|
||||
|
||||
`spdk_scsi_lun_get_dif_ctx` now takes an additional argument of type `spdk_scsi_task`.
|
||||
|
||||
### sock
|
||||
|
||||
Added spdk_sock_writev_async for performing asynchronous writes to sockets. This call will
|
||||
never return EAGAIN, instead queueing internally until the data has all been sent. This can
|
||||
simplify many code flows that create pollers to continue attempting to flush writes
|
||||
on sockets.
|
||||
|
||||
Added `impl_name` parameter in spdk_sock_listen and spdk_sock_connect functions. Users may now
|
||||
specify the sock layer implementation they'd prefer to use. Valid implementations are currently
|
||||
"vpp" and "posix" and NULL, where NULL results in the previous behavior of the functions.
|
||||

### isa-l

### thread

||||
### nvme
|
||||
|
||||
`spdk_thread_send_msg` now returns int indicating if the message was successfully sent.
|
||||
`delayed_pcie_doorbell` parameter in `spdk_nvme_io_qpair_opts` was renamed to `delay_cmd_submit`
|
||||
to allow reuse in other transports.
|
||||
|
||||
A new function `spdk_thread_send_critical_msg`, has been added to support sending a single message from
|
||||
a context that may be interrupted, e.g. a signal handler.
|
||||
Added RDMA WR batching to NVMf RDMA initiator. Send and receive WRs are chained together
|
||||
and posted with a single call to ibv_post_send(receive) in the next call to qpair completion
|
||||
processing function. Batching is controlled by 'delay_cmd_submit' qpair option.
|
||||
|
||||
Two new functions, `spdk_poller_pause`, and `spdk_poller_resume`, have been added to give greater control
|
||||
of pollers to the application owner.
|
||||
The NVMe-oF initiator now supports plugging out of tree NVMe-oF transports. In order
|
||||
to facilitate this feature, several small API changes have been made:

||||

||||
### blobfs
|
||||
The `spdk_nvme_transport_id` struct now contains a trstring member used to identify the transport.
|
||||
A new function, `spdk_nvme_transport_available_by_name`, has been added.
|
||||
A function table, `spdk_nvme_transport_ops`, and macro, `SPDK_NVME_TRANSPORT_REGISTER`, have been added which
|
||||
enable registering out of tree transports.
|
||||
|
||||
Added boolean return value for function spdk_fs_set_cache_size to indicate its operation result.
|
||||
A new function, `spdk_nvme_ns_supports_compare`, allows a user to check whether a given namespace supports the compare
|
||||
operation.
|
||||
|
||||
Added `blobfs_set_cache_size` RPC method to set cache size for blobstore filesystem.
|
||||
A new family of functions, `spdk_nvme_ns_compare*`, give the user access to submitting compare commands to NVMe namespaces.
|
||||
|
||||
A new function, `spdk_nvme_ctrlr_cmd_get_log_page_ext`, gives users more granular control over the command dwords sent in
|
||||
log page requests.
|
||||
|
||||
### nvmf
