Deprecation Notices
-------------------
+* The EAL function pci_config_space_set is deprecated in release 16.04
+ and will be removed from 16.07.
+ Macros CONFIG_RTE_PCI_CONFIG, CONFIG_RTE_PCI_EXTENDED_TAG and
+ CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE will be removed.
+ The /sys entries extended_tag and max_read_request_size created by igb_uio
+ will be removed.
+
* The following fields have been deprecated in rte_eth_stats:
ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
-* The ethdev structures rte_eth_link, rte_eth_dev_info and rte_eth_conf
- must be updated to support 100G link and to have a cleaner link speed API.
-
-* ABI changes is planned for the reta field in struct rte_eth_rss_reta_entry64
- which handles at most 256 queues (8 bits) while newer NICs support larger
- tables (512 queues).
- It should be integrated in release 2.3.
-
-* ABI changes are planned for struct rte_eth_fdir_flow in order to support
- extend flow director's input set. The release 2.2 does not contain these ABI
- changes, but release 2.3 will, and no backwards compatibility is planned.
-
-* ABI changes are planned for rte_eth_ipv4_flow and rte_eth_ipv6_flow to
- include more fields to be matched against. The release 2.2 does not
- contain these ABI changes, but release 2.3 will.
-
* ABI changes are planned for adding four new flow types. This impacts
RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
- but release 2.3 will.
-
-* ABI changes are planned for rte_eth_tunnel_filter_conf. Change the fields
- of outer_mac and inner_mac from pointer to struct in order to keep the
- code's readability. The release 2.2 does not contain these ABI changes, but
- release 2.3 will, and no backwards compatibility is planned.
-
-* The scheduler statistics structure will change to allow keeping track of
- RED actions.
-
-* librte_pipeline: The prototype for the pipeline input port, output port
- and table action handlers will be updated:
- the pipeline parameter will be added, the packets mask parameter will be
- either removed (for input port action handler) or made input-only.
-
-* ABI changes are planned in cmdline buffer size to allow the use of long
- commands (such as RETA update in testpmd). This should impact
- CMDLINE_PARSE_RESULT_BUFSIZE, STR_TOKEN_SIZE and RDLINE_BUF_SIZE.
- It should be integrated in release 2.3.
+ but release 2.3 will. [postponed]
+
+* ABI change is planned for the rte_mempool structure to allow mempool
+ cache support to be dynamic depending on the mempool being created
+ needing cache support. Saves about 1.5M of memory per rte_mempool structure
+ by removing the per lcore cache memory. Change will occur in DPDK 16.07
+ release and will skip the define RTE_NEXT_ABI in DPDK 16.04 release. The
+ code affected is app/test/test_mempool.c and librte_mempool/rte_mempool.[ch].
+ The rte_mempool.local_cache will be converted from an array to a pointer to
+ allow for dynamic allocation of the per lcore cache memory.
+
+* The rte_mempool struct will be changed in 16.07 to facilitate the new
+ external mempool manager functionality.
+ The ring element will be replaced with a more generic 'pool' opaque pointer
+ to allow new mempool handlers to use their own user-defined mempool
+ layout. Also newly added to rte_mempool is a handler index.
+ The existing API will be backward compatible, but there will be new API
+ functions added to facilitate the creation of mempools using an external
+ handler. The 16.07 release will contain these changes.
+
+* The rte_mempool allocation will be changed in 16.07:
+ allocation of large mempool in several virtual memory chunks, new API
+ to populate a mempool, new API to free a mempool, allocation in
+ anonymous mapping, drop of specific dom0 code. These changes will
+ induce a modification of the rte_mempool structure, plus a
+ modification of the API of rte_mempool_obj_iter(), implying a breakage
+ of the ABI.
