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.

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.

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.

This is only effective if the camera + uses a stv0672 coprocessor. + + Setting the options: + -------------------- + If you are using modules, edit /etc/modules.conf and add an options +line like this: + options cpia2 num_buffers=3 buffer_size=65535 + + If the driver is compiled into the kernel, at boot time specify them +like this: + cpia2.num_buffers=3 cpia2.buffer_size=65535 + + What buffer size should I use? + ------------------------------ + The maximum image size depends on the alternate you choose, and the +frame rate achieved by the camera. 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. In +order to avoid confusion, here it is called mview. There is also the qx5view +program which can also control the lights on the qx5 microscope. MJPEG Tools +(http://mjpeg.sourceforge.net) can also be used to record from the camera. + +5.

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. It contains +registers that control housekeeping functions such as powering up the video +processor. The video processor is the VP block. These registers control +how the video from the sensor is processed. Examples are timing registers, +user mode (vga, qvga), scaling, cropping, framerates, and so on. 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 repeat mode is only +used by VP4 to load a firmware patch. It contains a starting address and +a sequence of bytes to be written into a gpio port.
