Subject: [dpdk-dev] [PATCH v4 10/14] virtio: pci: add dummy func definition for in/outb for non-x86 arch
Date: Thu, 14 Jan 2016 18:58:33 +0530	[thread overview]
Message-ID: <1452778117-30178-11-git-send-email-sshukla@mvista.com> (raw)
In-Reply-To: <1452778117-30178-1-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)

Signed-off-by: Santosh Shukla <sshukla@mvista.com>

v4:
- dummy inb/outb function useful for non-x86 archs, Intent to get-rid of build
  error.
