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

`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.
