Linux-2.6.12-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!

+ 13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an

+ Gameport support is for the standard 15-pin PC gameport. If you

+ or anything else that uses the gameport, say Y or M here and also to
+ at least one of the hardware specific drivers.
+
+ For Ensoniq AudioPCI (ES1370), AudioPCI 97 (ES1371), ESS Solo1,
+ S3 SonicVibes, Trident 4DWave, SiS7018, and ALi 5451 gameport
+ support is provided by the sound drivers, so you won't need any
+ from the below listed modules. You still need to say Y here.
+
+ If unsure, say Y.
+
+ To compile this driver as a module, choose M here: the
+ module will be called gameport.

+# not selected, empty stubs are provided for the functions and all is
+# well.
+# If GAMEPORT is built in, everything is fine.
+# If GAMEPORT is a module, however, it would need to be loaded for the

+# driver must be a module as well in that case. Since there's no way
+# to express that directly in Kconfig, we use SOUND_GAMEPORT to

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

+ * LK keyboard driver for Linux, based on sunkbd.c (C) by Vojtech Pavlik
+ */
+
+/*
+ * DEC LK201 and LK401 keyboard driver for Linux (primary for DECstations
+ * and VAXstations, but can also be used on any standard RS232 with an
+ * adaptor).
+ *
+ * DISCLAIMER: This works for _me_. If you break anything by using the
+ * information given below, I will _not_ be liable!
+ *
+ * RJ10 pinout: To DE9: Or DB25:
+ * 1 - RxD <----> Pin 3 (TxD) <-> Pin 2 (TxD)
+ * 2 - GND <----> Pin 5 (GND) <-> Pin 7 (GND)
+ * 4 - TxD <----> Pin 2 (RxD) <-> Pin 3 (RxD)
+ * 3 - +12V (from HDD drive connector), DON'T connect to DE9 or DB25!!!
+ *
+ * Pin numbers for DE9 and DB25 are noted on the plug (quite small:). For
+ * RJ10, it's like this:
+ *
+ * __=__ Hold the plug in front of you, cable downwards,
+ * /___/| nose is hidden behind the plug. Now, pin 1 is at
+ * |1234|| the left side, pin 4 at the right and 2 and 3 are
+ * |IIII|| in between, of course:)
+ * | ||
+ * |____|/
+ * || So the adaptor consists of three connected cables
+ * || for data transmission (RxD and TxD) and signal ground.
+ * Additionally, you have to get +12V from somewhere.
+ * Most easily, you'll get that from a floppy or HDD power connector.
+ * It's the yellow cable there (black is ground and red is +5V).
+ *
+ * The keyboard and all the commands it understands are documented in
+ * "VCB02 Video Subsystem - Technical Manual", EK-104AA-TM-001. This
+ * document is LK201 specific, but LK401 is mostly compatible. It comes
+ * up in LK201 mode and doesn't report any of the additional keys it
+ * has. These need to be switched on with the LK_CMD_ENABLE_LK401
+ * command. You'll find this document (scanned .pdf file) on MANX,
+ * a search engine specific to DEC documentation. Try
+ * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1

+ * Building an adaptor to DE9 / DB25 RS232
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * DISCLAIMER: Use this description AT YOUR OWN RISK! I'll not pay for
+ * anything if you break your mouse, your computer or whatever!
+ *
+ * In theory, this mouse is a simple RS232 device. In practice, it has got
+ * a quite uncommon plug and the requirement to additionally get a power
+ * supply at +5V and -12V.
+ *
+ * If you look at the socket/jack (_not_ at the plug), we use this pin
+ * numbering:
+ * _______
+ * / 7 6 5 \
+ * | 4 --- 3 |
+ * \ 2 1 /
+ * -------
+ *
+ * DEC socket DE9 DB25 Note
+ * 1 (GND) 5 7 -
+ * 2 (RxD) 2 3 -
+ * 3 (TxD) 3 2 -
+ * 4 (-12V) - - Somewhere from the PSU. At ATX, it's
+ * the thin blue wire at pin 12 of the
+ * ATX power connector. Only required for
+ * VSXXX-AA/-GA mice.
+ * 5 (+5V) - - PSU (red wires of ATX power connector
+ * on pin 4, 6, 19 or 20) or HDD power
+ * connector (also red wire).
+ * 6 (+12V) - - HDD power connector, yellow wire. Only
+ * required for VSXXX-AB digitizer.
+ * 7 (dev. avail.) - - The mouse shorts this one to pin 1.
+ * This way, the host computer can detect
+ * the mouse. To use it with the adaptor,
+ * simply don't connect this pin.
+ *
+ * So to get a working adaptor, you need to connect the mouse with three
+ * wires to a RS232 port and two or three additional wires for +5V, +12V and
+ * -12V to the PSU.
+ *
+ * Flow specification for the link is 4800, 8o1.
+ *
+ * The mice and tablet are described in "VCB02 Video Subsystem - Technical
+ * Manual", DEC EK-104AA-TM-001. You'll find it at MANX, a search engine
+ * specific for DEC documentation. Try
+ * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1

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

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