Subject: [dpdk-dev] [PATCH] doc: announce ethdev port freeing on close operation
Date: Tue,  4 Aug 2020 11:20:14 +0200
Message-ID: <20200804092014.3335076-1-thomas@monjalon.net> (raw)

Since DPDK 18.11, some drivers are migrating to a new behaviour,
releasing port resources on close.
The temporary flag RTE_ETH_DEV_CLOSE_REMOVE triggers this new mode
in the migrated drivers.
After 2 years, the flag and the old behaviour will be removed.
Last drivers not migrated will have to complete the switch.

+* ethdev: The temporary flag RTE_ETH_DEV_CLOSE_REMOVE will be removed in 20.11.
+  As a consequence, the new behaviour introduced in 18.11 will be effective
+  for all drivers: generic port resources are freed on close operation.
+  Private resources are expected to be released in the ``dev_close`` callback.
+  More details in http://inbox.dpdk.org/dev/5248162.j6AOsuQRmx@thomas/
+
 * ethdev: New offload flags ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 19.11.
   This will allow application to enable or disable PMDs from updating
   ``rte_mbuf::hash::fdir``.
