Introduction - - This document describes the revision 1.06 and 1.07 of SiS 900/7016 - Fast Ethernet device driver under Linux. The driver is developed by - Silicon Integrated System Corp. and distributed freely under the GNU - General Public License (GPL). The driver can be compiled as a loadable - module and used under Linux kernel version 2.2.x. (rev. 1.06) With - minimal changes, the driver can also be used under 2.3.x and 2.4.x - kernel (rev. 1.07), please see Chapter 5. If you are intended to use - the driver for earlier kernels, you are on your own. - - The driver is tested with usual TCP/IP applications including FTP, - Telnet, Netscape etc. and is used constantly by the developers. - - Please send all comments/fixes/questions to Lei-Chun Chang. - _________________________________________________________________ - -Chapter 2. Changes - - Changes made in Revision 1.07 - - 1. Separation of sis900.c and sis900.h in order to move most constant - definition to sis900.h (many of those constants were corrected) - 2. Clean up PCI detection, the pci-scan from Donald Becker were not - used, just simple pci_find_*. - 3. MII detection is modified to support multiple mii transceiver. - 4. Bugs in read_eeprom, mdio_* were removed. - 5. Lot of sis900 irrelevant comments were removed/changed and more - comments were added to reflect the real situation. - 6. Clean up of physical/virtual address space mess in buffer - descriptors. - 7. Better transmit/receive error handling. - 8. The driver now uses zero-copy single buffer management scheme to - improve performance. - 9. Names of variables were changed to be more consistent. - 10. Clean up of auo-negotiation and timer code. - 11. Automatic detection and change of PHY on the fly. - 12. Bug in mac probing fixed. - 13. Fix 630E equalier problem by modifying the equalizer workaround - rule. - 14. Support for ICS1893 10/100 Interated PHYceiver. - 15. Support for media select by ifconfig. - 16. Added kernel-doc extratable documentation. - _________________________________________________________________ - -Chapter 3. Tested Environment - - This driver is developed on the following hardware - - * Intel Celeron 500 with SiS 630 (rev 02) chipset - * SiS 900 (rev 01) and SiS 7016/7014 Fast Ethernet Card - - and tested with these software environments - - * Red Hat Linux version 6.2 - * Linux kernel version 2.4.0 - * Netscape version 4.6 - * NcFTP 3.0.0 beta 18 - * Samba version 2.0.3 - _________________________________________________________________ - -Chapter 4. Files in This Package - - In the package you can find these files: - - sis900.c - Driver source file in C - - sis900.h - Header file for sis900.c - - sis900.sgml - DocBook SGML source of the document - - sis900.txt - Driver document in plain text - _________________________________________________________________ - -Chapter 5. Installation - - Silicon Integrated System Corp. is cooperating closely with core Linux - Kernel developers. The revisions of SiS 900 driver are distributed by - the usuall channels for kernel tar files and patches. Those kernel tar - files for official kernel and patches for kernel pre-release can be - download at official kernel ftp site and its mirrors. The 1.06 - revision can be found in kernel version later than 2.3.15 and - pre-2.2.14, and 1.07 revision can be found in kernel version 2.4.0. If - you have no prior experience in networking under Linux, please read - Ethernet HOWTO and Networking HOWTO available from Linux Documentation - Project (LDP). - - The driver is bundled in release later than 2.2.11 and 2.3.15 so this - is the most easy case. Be sure you have the appropriate packages for - compiling kernel source. Those packages are listed in Document/Changes - in kernel source distribution. If you have to install the driver other - than those bundled in kernel release, you should have your driver file - sis900.c and sis900.h copied into /usr/src/linux/drivers/net/ first. - There are two alternative ways to install the driver - _________________________________________________________________ - -Building the driver as loadable module - - To build the driver as a loadable kernel module you have to - reconfigure the kernel to activate network support by - -make menuconfig - - Choose "Loadable module support --->", then select "Enable loadable - module support". - - Choose "Network Device Support --->", select "Ethernet (10 or - 100Mbit)". Then select "EISA, VLB, PCI and on board controllers", and - choose "SiS 900/7016 PCI Fast Ethernet Adapter support" to "M". - - After reconfiguring the kernel, you can make the driver module by - -make modules - - The driver should be compiled with no errors. After compiling the - driver, the driver can be installed to proper place by - -make modules_install - - Load the driver into kernel by - -insmod sis900 - - When loading the driver into memory, some information message can be - view by - -dmesg - - or -cat /var/log/message - - If the driver is loaded properly you will have messages similar to - this: - -sis900.c: v1.07.06 11/07/2000 -eth0: SiS 900 PCI Fast Ethernet at 0xd000, IRQ 10, 00:00:e8:83:7f:a4. -eth0: SiS 900 Internal MII PHY transceiver found at address 1. -eth0: Using SiS 900 Internal MII PHY as default - - showing the version of the driver and the results of probing routine. - - Once the driver is loaded, network can be brought up by - -/sbin/ifconfig eth0 IPADDR broadcast BROADCAST netmask NETMASK media TYPE - - where IPADDR, BROADCAST, NETMASK are your IP address, broadcast - address and netmask respectively. TYPE is used to set medium type used - by the device. Typical values are "10baseT"(twisted-pair 10Mbps - Ethernet) or "100baseT" (twisted-pair 100Mbps Ethernet). For more - information on how to configure network interface, please refer to - Networking HOWTO. - - The link status is also shown by kernel messages. For example, after - the network interface is activated, you may have the message: - -eth0: Media Link On 100mbps full-duplex - - If you try to unplug the twist pair (TP) cable you will get - -eth0: Media Link Off - - indicating that the link is failed. - _________________________________________________________________ - -Building the driver into kernel - - If you want to make the driver into kernel, choose "Y" rather than "M" - on "SiS 900/7016 PCI Fast Ethernet Adapter support" when configuring - the kernel. Build the kernel image in the usual way - -make clean - -make bzlilo - - Next time the system reboot, you have the driver in memory. - _________________________________________________________________ - -Chapter 6. Known Problems and Bugs - - There are some known problems and bugs. If you find any other bugs - please mail to lcchang@sis.com.tw - - 1. AM79C901 HomePNA PHY is not thoroughly tested, there may be some - bugs in the "on the fly" change of transceiver. - 2. A bug is hidden somewhere in the receive buffer management code, - the bug causes NULL pointer reference in the kernel. This fault is - caught before bad things happen and reported with the message: - eth0: NULL pointer encountered in Rx ring, skipping which can be - viewed with dmesg or cat /var/log/message. - 3. The media type change from 10Mbps to 100Mbps twisted-pair ethernet - by ifconfig causes the media link down. - _________________________________________________________________ - -Chapter 7. Revision History - - * November 13, 2000, Revision 1.07, seventh release, 630E problem - fixed and further clean up. - * November 4, 1999, Revision 1.06, Second release, lots of clean up - and optimization. - * August 8, 1999, Revision 1.05, Initial Public Release - _________________________________________________________________ - -Chapter 8.

Overview and features +======================== +This driver supports the video interface of the devices mounting the ZC0301 +Image Processor and Control Chip. + +The driver relies on the Video4Linux2 and USB core modules. It has been +designed to run properly on SMP systems as well. + +The latest version of the ZC0301 driver can be found at the following URL: +http://www.linux-projects.org/ + +Some of the features of the driver are: + +- full compliance with the Video4Linux2 API (see also "Notes for V4L2 + application developers" paragraph); +- available mmap or read/poll methods for video streaming through isochronous + data transfers; +- automatic detection of image sensor; +- video format is standard JPEG; +- dynamic driver control thanks to various module parameters (see "Module + parameters" paragraph); +- up to 64 cameras can be handled at the same time; they can be connected and + disconnected from the host many times without turning off the computer, if + the system supports hotplugging; + + +5. Module dependencies +====================== +For it to work properly, the driver needs kernel support for Video4Linux and +USB. + +The following options of the kernel configuration file must be enabled and +corresponding modules must be compiled: + + # Multimedia devices + # + CONFIG_VIDEO_DEV=m + + # USB support + # + CONFIG_USB=m + +In addition, depending on the hardware being used, the modules below are +necessary: + + # USB Host Controller Drivers + # + CONFIG_USB_EHCI_HCD=m + CONFIG_USB_UHCI_HCD=m + CONFIG_USB_OHCI_HCD=m + +The ZC0301 controller also provides a built-in microphone interface.

Introduction + + This is a driver for STMicroelectronics's CPiA2 (second generation +Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG +stream at up to vga size. It implements the Video4Linux interface as much as +possible. Since the V4L interface does not support compressed formats, only +an mjpeg enabled application can be used with the camera. We have modified the +gqcam application to view this stream. + + The driver is implemented as two kernel modules. The cpia2 module +contains the camera functions and the V4L interface. The cpia2_usb module +contains usb specific functions. The main reason for this was the size of the +module was getting out of hand, so I separted them. It is not likely that +there will be a parallel port version. + +FEATURES: + - Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos + sensors. I only have the vga sensor, so can't test the other. + - Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between. + VGA and QVGA are the native image sizes for the VGA camera. CIF is done + in the coprocessor by scaling QVGA. All other sizes are done by clipping. + - Palette: YCrCb, compressed with MJPEG. + - Some compression parameters are settable. + - Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA). + - Adjust brightness, color, contrast while streaming. + - Flicker control settable for 50 or 60 Hz mains frequency. + +2. Making and installing the stv672 driver modules: + + Requirements: + ------------- + This should work with 2.4 (2.4.23 and later) and 2.6 kernels, but has +only been tested on 2.6. Video4Linux must be either compiled into the kernel or +available as a module. Video4Linux2 is automatically detected and made +available at compile time. + + Compiling: + ---------- + As root, do a make install. This will compile and install the modules +into the media/video directory in the module tree. For 2.4 kernels, use +Makefile_2.4 (aka do make -f Makefile_2.4 install). + + Setup: + ------ + Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This +may be done automatically by your distribution. + +3.

If the compression engine is able to +keep up with the frame rate, the maximum image size is given by the table +below. + The compression engine starts out at maximum compression, and will +increase image quality until it is close to the size in the table. As long +as the compression engine can keep up with the frame rate, after a short time +the images will all be about the size in the table, regardless of resolution. + At low alternate settings, the compression engine may not be able to +compress the image enough and will reduce the frame rate by producing larger +images. + The default of 68k should be good for most users. This will handle +any alternate at frame rates down to 15fps.

With only 2, +it is possible for the camera to finish sending one image just after a +program has started reading the other. If this happens, the driver must drop +a frame. The exception to this is if you have a heavily loaded machine. In +this case use 2 buffers. You are probably not reading at the full frame rate. +If the camera can send multiple images before a read finishes, it could +overwrite the third buffer before the read finishes, leading to a corrupt +image. Single and double buffering have extra checks to avoid overwriting. + +4. Using the camera + + We are providing a modified gqcam application to view the output.

There are two versions. The first is the +STV0672, which is capable of up to 30 frames per second (fps) in frame sizes +up to CIF, and 15 fps for VGA frames. The STV0676 is an improved version, +which can handle up to 30 fps VGA. Both coprocessors can be attached to two +CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor. These will +be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors. + +The two chipsets operate almost identically. The core is an 8051 processor, +running two different versions of firmware. The 672 runs the VP4 video +processor code, the 676 runs VP5. There are a few differences in register +mappings for the two chips. In these cases, the symbols defined in the +header files are marked with VP4 or VP5 as part of the symbol name. + +The cameras appear externally as three sets of registers. Setting register +values is the only way to control the camera. Some settings are +interdependant, such as the sequence required to power up the camera. I will +try to make note of all of these cases. + +The register sets are called blocks. Block 0 is the system block. This +section is always powered on when the camera is plugged in.

The last +block is the video compressor (VC). The video stream sent from the camera is +compressed as Motion JPEG (JPEGA). The VC controls all of the compression +parameters. Looking at the file cpia2_registers.h, you can get a full view +of these registers and the possible values for most of them. + +One or more registers can be set or read by sending a usb control message to +the camera. There are three modes for this. Block mode requests a number +of contiguous registers. Random mode reads or writes random registers with +a tuple structure containing address/value pairs.

The + * BR/~D line on the chip is brought high to signal 'command mode', + * where a command byte is sent to select the baudrate of the RS232 + * interface and the pulse length of the IRDA output. When BR/~D + * is brought low, the dongle then changes to the selected baudrate, + * and the RS232 interface is used for data until BR/~D is brought + * high again. The initial speed for the TOIMx323 after RESET is + * 9600 baud. The baudrate for command-mode is the last selected + * baud-rate, or 9600 after a RESET. + * + * The dongle I have (below) adds some extra hardware on the front end, + * but this is mostly directed towards pariasitic power from the RS232 + * line rather than changing very much about how to communicate with + * the TOIM3232. + * + * The protocol to talk to the TOIM4232 chipset seems to be almost + * identical to the TOIM3232 (and the 4232 datasheet is more detailed) + * so this code will probably work on that as well, although I haven't + * tested it on that hardware. + * + * Target dongle variations that might be common: + * + * DTR and RTS function: + * The data sheet for the 4232 has a sample implementation that hooks the + * DTR and RTS lines to the RESET and BaudRate/~Data lines of the + * chip (through line-converters). Given both DTR and RTS would have to + * be held low in normal operation, and the TOIMx232 requires +5V to + * signal ground, most dongle designers would almost certainly choose + * an implementation that kept at least one of DTR or RTS high in + * normal operation to provide power to the dongle, but will likely + * vary between designs. + * + * User specified command bits: + * There are two user-controllable output lines from the TOIMx232 that + * can be set low or high by setting the appropriate bits in the + * high-nibble of the command byte (when setting speed and pulse length). + * These might be used to switch on and off added hardware or extra + * dongle features. + * + * + * Target hardware: IRWave IR320ST-2 + * + * The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic + * TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transciever. + * It uses a hex inverter and some discrete components to buffer and + * line convert the RS232 down to 5V. + * + * The dongle is powered through a voltage regulator, fed by a large + * capacitor. To switch the dongle on, DTR is brought high to charge + * the capacitor and drive the voltage regulator. DTR isn't associated + * with any control lines on the TOIM3232. Parisitic power is also taken + * from the RTS, TD and RD lines when brought high, but through resistors. + * When DTR is low, the circuit might lose power even with RTS high. + * + * RTS is inverted and attached to the BR/~D input pin. When RTS + * is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode. + * RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command + * mode'. + * + * For some unknown reason, the RESET line isn't actually connected + * to anything. This means to reset the dongle to get it to a known + * state (9600 baud) you must drop DTR and RTS low, wait for the power + * capacitor to discharge, and then bring DTR (and RTS for data mode) + * high again, and wait for the capacitor to charge, the power supply + * to stabilise, and the oscillator clock to stabilise. + * + * Fortunately, if the current baudrate is known, the chipset can + * easily change speed by entering command mode without having to + * reset the dongle first. + * + * Major Components: + * + * - Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings + * to IRDA pulse timings + * - 3.6864MHz crystal to drive TOIM3232 clock oscillator + * - DM74lS04M Inverting Hex line buffer for RS232 input buffering + * and level conversion + * - PJ2951AC 150mA voltage regulator + * - Vishay/Temic TFDS4500 SIR IRDA front-end transceiver + * + */ + +#include +#include +#include + +#include + +#include "sir-dev.h" + +static int toim3232delay = 150; /* default is 150 ms */ +module_param(toim3232delay, int, 0); +MODULE_PARM_DESC(toim3232delay, "toim3232 dongle write complete delay"); + +#if 0 +static int toim3232flipdtr = 0; /* default is DTR high to reset */ +module_param(toim3232flipdtr, int, 0); +MODULE_PARM_DESC(toim3232flipdtr, "toim3232 dongle invert DTR (Reset)"); + +static int toim3232fliprts = 0; /* default is RTS high for baud change */ +module_param(toim3232fliptrs, int, 0); +MODULE_PARM_DESC(toim3232fliprts, "toim3232 dongle invert RTS (BR/D)"); +#endif + +static int toim3232_open(struct sir_dev *); +static int toim3232_close(struct sir_dev *); +static int toim3232_change_speed(struct sir_dev *, unsigned); +static int toim3232_reset(struct sir_dev *); + +#define TOIM3232_115200 0x00 +#define TOIM3232_57600 0x01 +#define TOIM3232_38400 0x02 +#define TOIM3232_19200 0x03 +#define TOIM3232_9600 0x06 +#define TOIM3232_2400 0x0A + +#define TOIM3232_PW 0x10 /* Pulse select bit */ + +static struct dongle_driver toim3232 = { + .owner = THIS_MODULE, + .driver_name = "Vishay TOIM3232", + .type = IRDA_TOIM3232_DONGLE, + .open = toim3232_open, + .close = toim3232_close, + .reset = toim3232_reset, + .set_speed = toim3232_change_speed, +}; + +static int __init toim3232_sir_init(void) +{ + if (toim3232delay < 1 || toim3232delay > 500) + toim3232delay = 200; + IRDA_DEBUG(1, "%s - using %d ms delay\n", + toim3232.driver_name, toim3232delay); + return irda_register_dongle(&toim3232); +} + +static void __exit toim3232_sir_cleanup(void) +{ + irda_unregister_dongle(&toim3232); +} + +static int toim3232_open(struct sir_dev *dev) +{ + struct qos_info *qos = &dev->qos; + + IRDA_DEBUG(2, "%s()\n", __FUNCTION__); + + /* Pull the lines high to start with. + * + * For the IR320ST-2, we need to charge the main supply capacitor to + * switch the device on.

First, all interfaces are searched - * for an AudioControl class interface. If found, the config descriptor - * that belongs to the current configuration is searched and - * the HEADER descriptor is found. It contains a list of - * all AudioStreaming and MIDIStreaming devices. This list is then walked, - * and all AudioStreaming interfaces are classified into input and output - * interfaces (according to the endpoint0 direction in altsetting1) (MIDIStreaming - * is currently not supported). The input & output list is then used - * to group inputs and outputs together and issued pairwise to the - * AudioStreaming class parser. Finally, all OUTPUT_TERMINAL descriptors - * are walked and issued to the mixer construction routine. - * - * The AudioStreaming parser simply enumerates all altsettings belonging - * to the specified interface. It looks for AS_GENERAL and FORMAT_TYPE - * class specific descriptors to extract the sample format/sample rate - * data. Only sample format types PCM and PCM8 are supported right now, and - * only FORMAT_TYPE_I is handled. The isochronous data endpoint needs to - * be the first endpoint of the interface, and the optional synchronisation - * isochronous endpoint the second one. - * - * Mixer construction works as follows: The various TERMINAL and UNIT - * descriptors span a tree from the root (OUTPUT_TERMINAL) through the - * intermediate nodes (UNITs) to the leaves (INPUT_TERMINAL). We walk - * that tree in a depth first manner. FEATURE_UNITs may contribute volume, - * bass and treble sliders to the mixer, MIXER_UNITs volume sliders. - * The terminal type encoded in the INPUT_TERMINALs feeds a heuristic - * to determine "meaningful" OSS slider numbers, however we will see - * how well this works in practice. Other features are not used at the - * moment, they seem less often used. Also, it seems difficult at least - * to construct recording source switches from SELECTOR_UNITs, but - * since there are not many USB ADC's available, we leave that for later. - */ - -/*****************************************************************************/ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include "audio.h" - -/* - * Version Information - */ -#define DRIVER_VERSION "v1.0.0" -#define DRIVER_AUTHOR "Alan Cox , Thomas Sailer (sailer@ife.ee.ethz.ch)" -#define DRIVER_DESC "USB Audio Class driver" - -#define AUDIO_DEBUG 1 - -#define SND_DEV_DSP16 5 - -#define dprintk(x) - -/* --------------------------------------------------------------------- */ - -/* - * Linked list of all audio devices... - */ -static struct list_head audiodevs = LIST_HEAD_INIT(audiodevs);
