Subject: [dpdk-dev] [PATCH v3 0/8] introduce DMA memory barriers
Date: Thu, 18 Jan 2018 16:44:22 -0800 [thread overview]
Message-ID: <20180119004430.15305-1-yskoh@mellanox.com> (raw)
In-Reply-To: <20180116011050.18866-1-yskoh@mellanox.com>
This patchset is to introduce DMA memory barriers, which could be more
efficient for coherent memory between I/O device and CPU, especially for
ARMv8.
v3:
* add more detailed comments about the new memory barriers.
v2:
* introduce DMA memory barriers.
Yongseok Koh (8):
eal: introduce DMA memory barriers
eal/x86: define DMA memory barriers
eal/ppc64: define DMA memory barriers
eal/armv7: define DMA memory barriers
eal/arm64: define DMA memory barriers
net/mlx5: remove unnecessary memory barrier
net/mlx5: replace IO memory barrier with DMA memory barrier
net/mlx5: fix synchonization on polling Rx completions
