@ -3,10 +3,26 @@ ALPS Touchpad Protocol
Introduction
------------
Currently the ALPS touchpad driver supports five protocol versions in use by
ALPS touchpads, called versions 1, 2, 3, 4 and 5.
Currently the ALPS touchpad driver supports four protocol versions in use by
ALPS touchpads, called versions 1, 2, 3, and 4. Information about the various
protocol versions is contained in the following sections.
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.

report" sequence: E8-E7-E7-E7-E9. The response is the model signature and is
matched against known models in the alps_model_data_array.
With protocol versions 3 and 4, the E7 report model signature is always
73-02-64. To differentiate between these versions, the response from the
"Enter Command Mode" sequence must be inspected as described below.
For older touchpads supporting protocol versions 3 and 4, the E7 report
model signature is always 73-02-64. To differentiate between these
versions, the response from the "Enter Command Mode" sequence must be
inspected as described below.
The new ALPS touchpads have an E7 signature of 73-03-50 or 73-03-0A but
seem to be better differentiated by the EC Command Mode response.

register. Registers are written by writing the value one nibble at a time
using the same encoding used for addresses.
For the new ALPS touchpads, the EC command is used to enter command
mode. The response in the new ALPS touchpads is significantly different,
and more important in determining the behavior. This code has been
separated from the original alps_model_data table and put in the
alps_identify function. For example, there seem to be two hardware init
sequences for the "Dolphin" touchpads as determined by the second byte
of the EC response.
Packet Format

well.
So far no v4 devices with tracksticks have been encountered.
ALPS Absolute Mode - Protocol Version 5
---------------------------------------
This is basically Protocol Version 3 but with different logic for packet
decode. It uses the same alps_process_touchpad_packet_v3 call with a
specialized decode_fields function pointer to correctly interpret the
packets. This appears to only be used by the Dolphin devices.
For single-touch, the 6-byte packet format is:
byte 0: 1 1 0 0 1 0 0 0
byte 1: 0 x6 x5 x4 x3 x2 x1 x0
byte 2: 0 y6 y5 y4 y3 y2 y1 y0
byte 3: 0 M R L 1 m r l
byte 4: y10 y9 y8 y7 x10 x9 x8 x7
byte 5: 0 z6 z5 z4 z3 z2 z1 z0
For mt, the format is:
byte 0: 1 1 1 n3 1 n2 n1 x24
byte 1: 1 y7 y6 y5 y4 y3 y2 y1
byte 2: ? x2 x1 y12 y11 y10 y9 y8

3.3 Multiqueue tuntap interface:
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.
#include <linux/if.h>
#include <linux/if_tun.h>
int tun_alloc_mq(char *dev, int queues, int *fds)
{
struct ifreq ifr;
int fd, err, i;
if (!dev)
return -1;
memset(&ifr, 0, sizeof(ifr));
/* Flags: IFF_TUN - TUN device (no Ethernet headers)
* IFF_TAP - TAP device
*
* IFF_NO_PI - Do not provide packet information
* IFF_MULTI_QUEUE - Create a queue of multiqueue device
*/
ifr.ifr_flags = IFF_TAP | IFF_NO_PI | IFF_MULTI_QUEUE;
strcpy(ifr.ifr_name, dev);
for (i = 0; i < queues; i++) {
if ((fd = open("/dev/net/tun", O_RDWR)) < 0)
goto err;
err = ioctl(fd, TUNSETIFF, (void *)&ifr);
if (err) {
close(fd);
goto err;
}
fds[i] = fd;
}
return 0;
err:
for (--i; i >= 0; i--)
close(fds[i]);
return err;
}
A new ioctl(TUNSETQUEUE) were introduced to enable or disable a queue. When
calling it with IFF_DETACH_QUEUE flag, the queue were disabled. And when
calling it with IFF_ATTACH_QUEUE flag, the queue were enabled. The queue were
enabled by default after it was created through TUNSETIFF.
fd is the file descriptor (queue) that we want to enable or disable, when
enable is true we enable it, otherwise we disable it
#include <linux/if.h>
#include <linux/if_tun.h>
int tun_set_queue(int fd, int enable)
{
struct ifreq ifr;
memset(&ifr, 0, sizeof(ifr));
if (enable)
ifr.ifr_flags = IFF_ATTACH_QUEUE;
else
ifr.ifr_flags = IFF_DETACH_QUEUE;
return ioctl(fd, TUNSETQUEUE, (void *)&ifr);
