Subject: [dpdk-dev] [PATCH v2 1/3] eal: move CACHE and IOVA related definitions
Date: Fri, 27 Sep 2019 14:50:52 +0100
Message-ID: <20190927135054.20845-2-konstantin.ananyev@intel.com> (raw)
In-Reply-To: <20190927135054.20845-1-konstantin.ananyev@intel.com>

Right now RTE_CACHE_ and IOVA definitions are located inside rte_memory.h
That might cause an unwanted inclusions of arch/os specific header files.
See [1] for particular problem example.
Probably the simplest way to deal with such problems -
move these definitions into rte_commmon.h

Note that this move doesn't introduce any change in functionality.
