Subject: [dpdk-stable] [PATCH v2] net/qede: support IOVA VA mode
Date: Fri, 8 Mar 2019 09:28:55 +0000 [thread overview]
Message-ID: <20190308092855.10942-1-ktraynor@redhat.com> (raw)
In-Reply-To: <20190307183903.10779-1-ktraynor@redhat.com>
Set RTE_PCI_DRV_IOVA_AS_VA in drv_flags. This allows initializing qede
PMD as non-root also on Linux v4.x, where /proc/self/pagemap can't be
acccessed without CAP_SYS_ADMIN privileges.
The flag was introduced generically but not in pmds in commit:
815c7deaed2d ("pci: get IOMMU class on Linux")
