Subject: [dpdk-dev] [PATCH v4] kni: add IOVA va support for kni
Date: Mon, 22 Apr 2019 10:09:12 +0530 [thread overview]
Message-ID: <20190422043912.18060-1-kirankumark@marvell.com> (raw)
Message-ID: <20190422043912.nToFw0SnmDfbQ19pl71v8xfmyuGI9FJTHKlZQpT0MCQ@z> (raw)
In-Reply-To: <20190416045556.9428-1-kirankumark@marvell.com>
From: Kiran Kumar K <kirankumark@marvell.com>
With current KNI implementation kernel module will work only in
IOVA=PA mode. This patch will add support for kernel module to work
with IOVA=VA mode.
The idea is to get the physical address from iova address using
api iommu_iova_to_phys. Using this API, we will get the physical
address from iova address and later use phys_to_virt API to
convert the physical address to kernel virtual address.
With this approach we have compared the performance with IOVA=PA
and there is no difference observed. Seems like kernel is the
overhead.
This approach will not work with the kernel versions less than 4.4.0
because of API compatibility issues.
Signed-off-by: Kiran Kumar K <kirankumark@marvell.com>

V4 changes:
* Fixed build issues with older kernel versions
* This approach will only work with kernel above 4.4.0
V3 Changes:
* Add new approach to work kni with IOVA=VA mode using
iommu_iova_to_phys API.
