## v25.05



### accel_mlx5



Added mlx5 platform driver capable of executing sequences of RDMA + crypto operations in one go.  It

utilizes UMR (User Memory Region) registration, which allows changing properties of memory keys,

which are then used by the NIC to perform the offload (e.g. encrypt/decrypt) while doing

RDMA_READ/RDMA_WRITE operations.



### python



Renamed python binaries with "-" instead of "_"

spdk-rpc, spdk-sma and spdk-cli to be more platform

independent for linux/windows according to pypi and hatch suggestions



### bdev



Added capability to insert/strip DIF from IOs in the bdev layer.  This allows users to to rely on

the bdev layer to generate and verify the integrity of the data.



Added support for inserting or overwriting metadata buffers depending on the NVMe PRACT bits set in

`spdk_bdev_ext_io_opts`.



Added `spdk_bdev_open_ext_v2()` API allowing for more flexible additions of per-open options.



Added APIs to retrieve metadata configuration depending on the `hide_metadata` option.



Added option to reset stats in `bdev_get_iostat` RPC.



Added option to specify the granularity and min/max values when enabling histogram for a bdev.  It

allows users to reduce the size of the histogram.



### bdev_compress



Added support for UNMAP.

Added public API `spdk_bdev_nvme_delete` to delete the specified NVMe controller or one of its paths.



### blobstore



Added support for variable metadata page size.



### env



Added 3 APIs to handle multiple interrupts for PCI device `spdk_pci_device_enable_interrupts()`,

`spdk_pci_device_disable_interrupts()`, and `spdk_pci_device_get_interrupt_efd_by_index()`.



Added `spdk_mem_get_numa_id()` API returning the NUMA node ID for the specified memory buffer.



### fsdev



Added `spdk_fsdev_mount()` and `spdk_fsdev_umount()` APIs, fsdev's equivalent of `FUSE_INIT` and

`FUSE_DESTROY`.  Removed `open_opts` parameter from `spdk_fsdev_open()`, as these options are part

of `spdk_fsdev_mount_opts`.



### fsdev_aio



Added option to skip read/write operations.  When enabled, `fsdev_aio` works similarly to

`bdev_null` and immediately completes IOs without actually executing them.  This option only changes

the behavior of READ and WRITE operations.



### log



Added `spdk_log_open_ext` API allowing users to set custom open and close callbacks.

Added `enable_interrupts` option to `spdk_nvme_ctrlr_opts`. If set to true then interrupts may be

Added `spdk_nvme_poll_group_get_fd_group()` API returning `fd_group` associated with an NVMe poll

group.



Added `spdk_nvme_poll_group_set_interrupt_callback()` API allowing users to register a callback to

Added `spdk_thread_register_post_poller_handler()` API to register a post poller handler.  It aims

at improving doorbell management by ensuring that a doorbell is rang after submitting all requests,

without waiting for the next poll cycle.



Added support for `fd_group`-based interrupts.  `spdk_interrupt_register_fd_group()` can be used to

register an interrupt listening on events from an `fd_group`.
