+Currently the ALPS touchpad driver supports five protocol versions in use by
+ALPS touchpads, called versions 1, 2, 3, 4 and 5.
+
+Since roughly mid-2010 several new ALPS touchpads have been released and
+integrated into a variety of laptops and netbooks.  These new touchpads
+have enough behavior differences that the alps_model_data definition
+table, describing the properties of the different versions, is no longer
+adequate.  The design choices were to re-define the alps_model_data
+table, with the risk of regression testing existing devices, or isolate
+the new devices outside of the alps_model_data table.  The latter design
+choice was made.  The new touchpad signatures are named: "Rushmore",
+"Pinnacle", and "Dolphin", which you will see in the alps.c code.
+For the purposes of this document, this group of ALPS touchpads will
+generically be called "new ALPS touchpads".
+
+We experimented with probing the ACPI interface _HID (Hardware ID)/_CID
+(Compatibility ID) definition as a way to uniquely identify the
+different ALPS variants but there did not appear to be a 1:1 mapping.
+In fact, it appeared to be an m:n mapping between the _HID and actual
+hardware type.

+
+  From version 3.8, Linux supports multiqueue tuntap which can uses multiple
+  file descriptors (queues) to parallelize packets sending or receiving. The
+  device allocation is the same as before, and if user wants to create multiple
+  queues, TUNSETIFF with the same device name must be called many times with
+  IFF_MULTI_QUEUE flag.
+
+  char *dev should be the name of the device, queues is the number of queues to
+  be created, fds is used to store and return the file descriptors (queues)
+  created to the caller. Each file descriptor were served as the interface of a
+  queue which could be accessed by userspace.

+          This option will modify all the calls to function tracing
+          dynamically (will patch them out of the binary image and
+          replace them with a No-Op instruction) on boot up. During
+          compile time, a table is made of all the locations that ftrace
+          can function trace, and this table is linked into the kernel
+          image. When this is enabled, functions can be individually
+          enabled, and the functions not enabled will not affect
+          performance of the system.
+

+            set_ftrace_filter

           This way a CONFIG_FUNCTION_TRACER kernel is slightly larger, but
           otherwise has native performance as long as no tracing is active.
 
-          The changes to the code are done by a kernel thread that
-          wakes up once a second and checks to see if any ftrace calls
-          were made. If so, it runs stop_machine (stops all CPUS)
-          and modifies the code to jump over the call to ftrace.
