Deprecation Notices ------------------- -* eal: DPDK runtime configuration file (located at - ``/var/run/.<prefix>_config``) will be moved. The new path will be as follows: - - - if DPDK is running as root, path will be set to - ``/var/run/dpdk/<prefix>/config`` - - if DPDK is not running as root and $XDG_RUNTIME_DIR is set, path will be set - to ``$XDG_RUNTIME_DIR/dpdk/<prefix>/config`` - - if DPDK is not running as root and $XDG_RUNTIME_DIR is not set, path will be - set to ``/tmp/dpdk/<prefix>/config`` - * eal: both declaring and identifying devices will be streamlined in v18.08. New functions will appear to query a specific port from buses, classes of device and device drivers. Device declaration will be made coherent with the diff --git a/doc/guides/rel_notes/release_18_08.rst b/doc/guides/rel_notes/release_18_08.rst index d41546c27..ebe7e6bd6 100644 --- a/doc/guides/rel_notes/release_18_08.rst +++ b/doc/guides/rel_notes/release_18_08.rst @@ -129,6 +129,13 @@ API Changes - ``RTE_COMP_FF_OOP_SGL_IN_LB_OUT`` - ``RTE_COMP_FF_OOP_LB_IN_SGL_OUT`` +* Path to runtime config file has changed.
