Subject: [dpdk-dev] [PATCH v3 0/3] force IOVA to a particular mode
Date: Wed, 3 Oct 2018 16:53:11 -0400 [thread overview]
Message-ID: <1538599994-23331-1-git-send-email-eric.zhang@windriver.com> (raw)
This patchset introduces an EAL command line option "--iova-mode"
to give the user a facility to force IOVA mode to a special value.
Auto detection of the IOVA mode, based on probing the bus and IOMMU
configuration, may not report the desired addressing mode when virtual
devices that are not directly attached to the bus are present.
The EAL command line option "--iova-mode" can be used to select either
physical addressing('pa') or virtual addressing('va').
------
v3:
* document --iova-mode EAL option
* change default iova mode to RTE_IOVA_DC
v2:
* use eal option instead of compilation option to configure IOVA
* apply http://patchwork.dpdk.org/patch/25192/
