Subject: [dpdk-dev] [PATCH v2] mempool/octeontx2: fix possible ABI break with force inline
Date: Thu, 18 Jul 2019 12:21:11 +0530 [thread overview]
Message-ID: <20190718065111.1766-1-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190717184013.1072-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Since direct register access is used in npa_lf_aura_op_alloc_bulk()
use __rte_noinline instead of __rte_always_inline to preserve ABI.
Based on the compiler npa_lf_aura_op_alloc_bulk might be inlined
differently which may lead to undefined behaviour due to handcoded
asm.
Fixes: 29893042c29d ("mempool/octeontx2: fix clang build for arm64")
