Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

9 or anything else that uses the gameport, say Y or M here and also to
10 at least one of the hardware specific drivers.

13 S3 SonicVibes, Trident 4DWave, SiS7018, and ALi 5451 gameport
14 support is provided by the sound drivers, so you won't need any
15 from the below listed modules. You still need to say Y here.

76# Some sound drivers call gameport functions. If GAMEPORT is
77# not selected, empty stubs are provided for the functions and all is
78# well.
79# If GAMEPORT is built in, everything is fine.
80# If GAMEPORT is a module, however, it would need to be loaded for the
81# sound driver to be able to link properly. Therefore, the sound
82# driver must be a module as well in that case. Since there's no way
83# to express that directly in Kconfig, we use SOUND_GAMEPORT to
84# express it. SOUND_GAMEPORT boils down to "if GAMEPORT is 'm',

14 * Driver to use Handykey's Twiddler (the first edition, i.e. the one with
15 * the RS232 interface) as a joystick under Linux
16 *
17 * The Twiddler is a one-handed chording keyboard featuring twelve buttons on
18 * the front, six buttons on the top, and a built-in tilt sensor. The buttons
19 * on the front, which are grouped as four rows of three buttons, are pressed
20 * by the four fingers (this implies only one button per row can be held down
21 * at the same time) and the buttons on the top are for the thumb. The tilt
22 * sensor delivers X and Y axis data depending on how the Twiddler is held.
23 * Additional information can be found at http://www.handykey.com.
24 *
25 * This driver does not use the Twiddler for its intended purpose, i.e. as
26 * a chording keyboard, but as a joystick: pressing and releasing a button
27 * immediately sends a corresponding button event, and tilting it generates
28 * corresponding ABS_X and ABS_Y events. This turns the Twiddler into a game
29 * controller with amazing 18 buttons :-)
30 *
31 * Note: The Twiddler2 (the successor of the Twiddler that connects directly
32 * to the PS/2 keyboard and mouse ports) is NOT supported by this driver!
33 *
34 * For questions or feedback regarding this driver module please contact:
35 * Arndt Schoenewald <arndt@quelltext.com>

10 * DEC LK201 and LK401 keyboard driver for Linux (primary for DECstations
11 * and VAXstations, but can also be used on any standard RS232 with an
12 * adaptor).
13 *
14 * DISCLAIMER: This works for _me_. If you break anything by using the
15 * information given below, I will _not_ be liable!
16 *
17 * RJ10 pinout: To DE9: Or DB25:
18 * 1 - RxD <----> Pin 3 (TxD) <-> Pin 2 (TxD)
19 * 2 - GND <----> Pin 5 (GND) <-> Pin 7 (GND)
20 * 4 - TxD <----> Pin 2 (RxD) <-> Pin 3 (RxD)
21 * 3 - +12V (from HDD drive connector), DON'T connect to DE9 or DB25!!!
22 *
23 * Pin numbers for DE9 and DB25 are noted on the plug (quite small:). For
24 * RJ10, it's like this:
25 *
26 * __=__ Hold the plug in front of you, cable downwards,
27 * /___/| nose is hidden behind the plug. Now, pin 1 is at
28 * |1234|| the left side, pin 4 at the right and 2 and 3 are
29 * |IIII|| in between, of course:)
30 * | ||
31 * |____|/
32 * || So the adaptor consists of three connected cables
33 * || for data transmission (RxD and TxD) and signal ground.
34 * Additionally, you have to get +12V from somewhere.
35 * Most easily, you'll get that from a floppy or HDD power connector.
36 * It's the yellow cable there (black is ground and red is +5V).
37 *
38 * The keyboard and all the commands it understands are documented in

31 * Building an adaptor to DE9 / DB25 RS232
32 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
33 *
34 * DISCLAIMER: Use this description AT YOUR OWN RISK! I'll not pay for
35 * anything if you break your mouse, your computer or whatever!
36 *
37 * In theory, this mouse is a simple RS232 device. In practice, it has got
38 * a quite uncommon plug and the requirement to additionally get a power
39 * supply at +5V and -12V.
40 *
41 * If you look at the socket/jack (_not_ at the plug), we use this pin
42 * numbering:
43 * _______
44 * / 7 6 5 \
45 * | 4 --- 3 |
46 * \ 2 1 /
47 * -------
48 *
49 * DEC socket DE9 DB25 Note
50 * 1 (GND) 5 7 -
51 * 2 (RxD) 2 3 -
52 * 3 (TxD) 3 2 -
53 * 4 (-12V) - - Somewhere from the PSU. At ATX, it's
54 * the thin blue wire at pin 12 of the
55 * ATX power connector. Only required for
56 * VSXXX-AA/-GA mice.
57 * 5 (+5V) - - PSU (red wires of ATX power connector
58 * on pin 4, 6, 19 or 20) or HDD power
59 * connector (also red wire).
60 * 6 (+12V) - - HDD power connector, yellow wire. Only
61 * required for VSXXX-AB digitizer.
62 * 7 (dev. avail.) - - The mouse shorts this one to pin 1.
63 * This way, the host computer can detect
64 * the mouse. To use it with the adaptor,
65 * simply don't connect this pin.
66 *
67 * So to get a working adaptor, you need to connect the mouse with three
68 * wires to a RS232 port and two or three additional wires for +5V, +12V and
69 * -12V to the PSU.
70 *
71 * Flow specification for the link is 4800, 8o1.
72 *
73 * The mice and tablet are described in "VCB02 Video Subsystem - Technical
74 * Manual", DEC EK-104AA-TM-001. You'll find it at MANX, a search engine
75 * specific for DEC documentation. Try
76 * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1

33 * Driver theory of operation:
34 *
35 * Some access methods and an ISR is defined by the sub-driver
36 * (e.g. hp_sdc_mlc.c). These methods are expected to provide a
37 * few bits of logic in addition to raw access to the HIL MLC,
38 * specifically, the ISR, which is entirely registered by the
39 * sub-driver and invoked directly, must check for record
40 * termination or packet match, at which point a semaphore must
41 * be cleared and then the hil_mlcs_tasklet must be scheduled.
42 *
43 * The hil_mlcs_tasklet processes the state machine for all MLCs
44 * each time it runs, checking each MLC's progress at the current
45 * node in the state machine, and moving the MLC to subsequent nodes
46 * in the state machine when appropriate. It will reschedule
47 * itself if output is pending. (This rescheduling should be replaced
48 * at some point with a sub-driver-specific mechanism.)
49 *
50 * A timer task prods the tasklet once per second to prevent
51 * hangups when attached devices do not return expected data
52 * and to initiate probes of the loop for new devices.

33 *
34 *
35 * Driver theory of operation:
36 *
37 * hp_sdc_put does all writing to the SDC. ISR can run on a different
38 * CPU than hp_sdc_put, but only one CPU runs hp_sdc_put at a time
39 * (it cannot really benefit from SMP anyway.) A tasket fit this perfectly.
40 *
41 * All data coming back from the SDC is sent via interrupt and can be read
42 * fully in the ISR, so there are no latency/throughput problems there.
43 * The problem is with output, due to the slow clock speed of the SDC
44 * compared to the CPU. This should not be too horrible most of the time,
45 * but if used with HIL devices that support the multibyte transfer command,
46 * keeping outbound throughput flowing at the 6500KBps that the HIL is
47 * capable of is more than can be done at HZ=100.
48 *
49 * Busy polling for IBF clear wastes CPU cycles and bus cycles. hp_sdc.ibf
50 * is set to 0 when the IBF flag in the status register has cleared. ISR
51 * may do this, and may also access the parts of queued transactions related
52 * to reading data back from the SDC, but otherwise will not touch the
53 * hp_sdc state. Whenever a register is written hp_sdc.ibf is set to 1.
54 *
55 * The i8042 write index and the values in the 4-byte input buffer
56 * starting at 0x70 are kept track of in hp_sdc.wi, and .r7[], respectively,
57 * to minimize the amount of IO needed to the SDC. However these values
58 * do not need to be locked since they are only ever accessed by hp_sdc_put.
59 *
60 * A timer task schedules the tasklet once per second just to make
61 * sure it doesn't freeze up and to allow for bad reads to time out.

43 * have a +5V pin, and feeding the keyboard from signal pins is out of question
44 * with 300 mA power reqirement of a typical AT keyboard.

65/* This driver emulates both protocols of the old h3600_ts and h3600_tsraw
66 * devices. The first one must output X/Y data in 'cooked' format, e.g.
67 * filtered, dejittered and calibrated. Second device just outputs raw
68 * data received from the hardware.
69 *
70 * This driver doesn't support filtering and dejittering; it supports only
71 * calibration. Filtering and dejittering must be done in the low-level
72 * driver, if needed, because it may gain additional benefits from knowing
73 * the low-level details, the nature of noise and so on.
74 *
75 * The driver precomputes a calibration matrix given the initial xres and
76 * yres values (quite innacurate for most touchscreens) that will result
77 * in a more or less expected range of output values. The driver supports
78 * the TS_SET_CAL ioctl, which will replace the calibration matrix with a
79 * new one, supposedly generated from the values taken from the raw device.
