Subject: [dpdk-stable] [PATCH v10 1/5] bus/fslmc: fix the conflicting dmb function
Date: Fri, 25 Oct 2019 23:39:07 +0800	[thread overview]
Message-ID: <1572017951-41253-2-git-send-email-gavin.hu@arm.com> (raw)
In-Reply-To: <1572017951-41253-1-git-send-email-gavin.hu@arm.com>
In-Reply-To: <1561911676-37718-1-git-send-email-gavin.hu@arm.com>

There are two definitions conflicting each other, for more
details, refer to [1].

include/rte_atomic_64.h:19: error: "dmb" redefined [-Werror]
drivers/bus/fslmc/mc/fsl_mc_sys.h:36: note: this is the location of the
previous definition
 #define dmb() {__asm__ __volatile__("" : : : "memory"); }

The fix is to reuse the EAL definition to avoid conflicts.
