Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+ tristate "IrDA (infrared) subsystem support"
+ select CRC_CCITT
+ ---help---
+ Say Y here if you want to build support for the IrDA (TM) protocols.
+ The Infrared Data Associations (tm) specifies standards for wireless
+ infrared communication and is supported by most laptops and PDA's.
+
+ To use Linux support for the IrDA (tm) protocols, you will also need
+ some user-space utilities like irattach. For more information, see
+ the file <file:Documentation/networking/irda.txt>. You also want to
+ read the IR-HOWTO, available at
+ <http://www.tldp.org/docs.html#howto>.
+
+ If you want to exchange bits of data (vCal, vCard) with a PDA, you
+ will need to install some OBEX application, such as OpenObex :
+ <http://sourceforge.net/projects/openobex/>
+
+ To compile this support as a module, choose M here: the module will
+ be called irda.

+ bool "Ultra (connectionless) protocol"
+ depends on IRDA
+ help
+ Say Y here to support the connectionless Ultra IRDA protocol.
+ Ultra allows to exchange data over IrDA with really simple devices
+ (watch, beacon) without the overhead of the IrDA protocol (no handshaking,
+ no management frames, simple fixed header).
+ Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

+config IRDA_CACHE_LAST_LSAP
+ bool "Cache last LSAP"
+ depends on IRDA
+ help
+ Say Y here if you want IrLMP to cache the last LSAP used. This
+ makes sense since most frames will be sent/received on the same
+ connection. Enabling this option will save a hash-lookup per frame.
+
+ If unsure, say Y.
+
+config IRDA_FAST_RR
+ bool "Fast RRs (low latency)"
+ depends on IRDA
+ ---help---
+ Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
+ when acting as a primary station.
+ Disabling this option will make latency over IrDA very bad. Enabling
+ this option will make the IrDA stack send more packet than strictly
+ necessary, thus reduce your battery life (but not that much).
+
+ Fast RR will make IrLAP send out a RR frame immediately when
+ receiving a frame if its own transmit queue is currently empty. This
+ will give a lot of speed improvement when receiving much data since
+ the secondary station will not have to wait the max. turn around
+ time (usually 500ms) before it is allowed to transmit the next time.
+ If the transmit queue of the secondary is also empty, the primary will
+ start backing-off before sending another RR frame, waiting longer
+ each time until the back-off reaches the max. turn around time.
+ This back-off increase in controlled via
+ /proc/sys/net/irda/fast_poll_increase
+
+ If unsure, say Y.
+
+config IRDA_DEBUG
+ bool "Debug information"
+ depends on IRDA
+ help
+ Say Y here if you want the IrDA subsystem to write debug information
+ to your syslog. You can change the debug level in
+ /proc/sys/net/irda/debug .
+ When this option is enabled, the IrDA also perform many extra internal
+ verifications which will usually prevent the kernel to crash in case of
+ bugs.
+
+ If unsure, say Y (since it makes it easier to find the bugs).
