## v20.10: (Upcoming Release)



### vhost



SPDK has switched to DPDK's rte_vhost library since 19.07 release, removed the internal

rte_vhost library which is used for DPDK older than 19.05, removed the experimental vhost

nvme target which depends on the internal rte_vhost library.



### thread



`fd_group` is applied to support interrupt mode.

New APIs were added to support an experimental interrupt mode.  This allows modules or

libraries to selectively register file descriptors that the spdk_thread can wait on,

as an alternative to polling. In v20.10, this functionality is enabled in a very small

subset of SPDK libraries and modules.



### util



A new utility named `fd_group` was add. It is now

implemented by epoll on Linux platform. It can be used by

spdk_thread and reactor to implement interrupt mode.

bdevperf enabled using the zcopy API by default which caused a performance impact of

up to 25% on bdevs that don't natively support zcopy because the API emulates zero-copy

by allocating a buffer. The bdevperf `-x` param was renamed to `-Z` and the default

value changed to false. For bdevs that support zcopy, use the -Z flag to enable
