Subject: [dpdk-dev] [PATCH v5 10/11] virtio: pci: add dummy func definition for in/outb for non-x86 arch
Date: Tue, 19 Jan 2016 17:16:11 +0530 [thread overview]
Message-ID: <1453203972-24855-11-git-send-email-sshukla@mvista.com> (raw)
In-Reply-To: <1453203972-24855-1-git-send-email-sshukla@mvista.com>
For non-x86 arch, Compiler will throw build error for in/out apis. Including
dummy api function so to pass build.
Note that: For virtio to work for non-x86 arch - RTE_EAL_VFIO is the only
supported method. RTE_EAL_IGB_UIO is not supported for non-x86 arch.
So, Virtio support for arch and supported interface by that arch:
ARCH IGB_UIO VFIO
x86 Y Y
ARM64 N/A Y
PPC_64 N/A Y (Not tested but likely should work, as vfio is
arch independent)
Note: Applicable for virtio spec 0.95
