+
+i. New template defined to represent each family of controllers (identified by processor used).
+ The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

+
+i. Code reorganized to remove code duplication in megasas_build_cmd.
+
+ "There's a lot of duplicate code megasas_build_cmd. Move that out of the different codepathes and merge the reminder of megasas_build_cmd into megasas_queue_command"
+
+ - Christoph Hellwig <hch@lst.de>
+
+ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
+
+ "MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"

+
+
+4. Overview and features
+========================
+This driver supports the video interface of the devices mounting the ET61X151
+or ET61X251 PC Camera Controllers.
+
+It's worth to note that Etoms Electronics has never collaborated with the
+author during the development of this project; despite several requests,
+Etoms Electronics also refused to release enough detailed specifications of
+the video compression engine.
+
+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 ET61X[12]51 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;
+- support for any window resolutions and optional panning within the maximum
+ pixel area of image sensor;
+- image downscaling with arbitrary scaling factors from 1 and 2 in both
+ directions (see "Notes for V4L2 application developers" paragraph);
+- two different video formats for uncompressed or compressed data in low or
+ high compression quality (see also "Notes for V4L2 application developers"
+ paragraph);
+- full support for the capabilities of every possible image sensors that can
+ be connected to the ET61X[12]51 bridges, including, for istance, red, green,
+ blue and global gain adjustments and exposure control (see "Supported
+ devices" paragraph for details);
+- use of default color settings for sunlight conditions;
+- dynamic I/O interface for both ET61X[12]51 and image sensor control (see
+ "Optional device control through 'sysfs'" paragraph);
+- 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;
+- no known bugs.
+
+
+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
+
+To enable advanced debugging functionality on the device through /sysfs:
+
+ # Multimedia devices
+ #
+ CONFIG_VIDEO_ADV_DEBUG=y
+
+ # 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
+
+And finally:
+
+ # USB Multimedia devices
+ #
+ CONFIG_USB_ET61X251=m
+
+
+6. Module loading
+=================
+To use the driver, it is necessary to load the "et61x251" module into memory
+after every other module required: "videodev", "usbcore" and, depending on
+the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd".
+
+Loading can be done as shown below:
+
+ [root@localhost home]# modprobe et61x251
+
+At this point the devices should be recognized. You can invoke "dmesg" to
+analyze kernel messages and verify that the loading process has gone well:
+
+ [user@localhost home]$ dmesg
+
+
+7. Module parameters
+====================
+Module parameters are listed below:
+-------------------------------------------------------------------------------
+Name: video_nr
+Type: short array (min = 0, max = 64)
+Syntax: <-1|n[,...]>
+Description: Specify V4L2 minor mode number:
+ -1 = use next available
+ n = use minor number n
+ You can specify up to 64 cameras this way.
+ For example:
+ video_nr=-1,2,-1 would assign minor number 2 to the second
+ registered camera and use auto for the first one and for every
+ other camera.
+Default: -1
+-------------------------------------------------------------------------------
+Name: force_munmap
+Type: bool array (min = 0, max = 64)
+Syntax: <0|1[,...]>
+Description: Force the application to unmap previously mapped buffer memory
+ before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
+ all the applications support this feature. This parameter is
+ specific for each detected camera.
+ 0 = do not force memory unmapping
+ 1 = force memory unmapping (save memory)
+Default: 0
+-------------------------------------------------------------------------------
+Name: debug
+Type: ushort
+Syntax: <n>
+Description: Debugging information level, from 0 to 3:
+ 0 = none (use carefully)
+ 1 = critical errors
+ 2 = significant informations
+ 3 = more verbose messages
+ Level 3 is useful for testing only, when only one device
+ is used at the same time. It also shows some more informations
+ about the hardware being detected. This module parameter can be
+ changed at runtime thanks to the /sys filesystem interface.
+Default: 2
+-------------------------------------------------------------------------------
+
+
+8. Optional device control through "sysfs"
+==========================================
+If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
+it is possible to read and write both the ET61X[12]51 and the image sensor
+registers by using the "sysfs" filesystem interface.
+
+There are four files in the /sys/class/video4linux/videoX directory for each
+registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files
+control the ET61X[12]51 bridge, while the other two control the sensor chip.
+"reg" and "i2c_reg" hold the values of the current register index where the
+following reading/writing operations are addressed at through "val" and
+"i2c_val". Their use is not intended for end-users, unless you know what you
+are doing. Remember that you must be logged in as root before writing to them.
+
+As an example, suppose we were to want to read the value contained in the
+register number 1 of the sensor register table - which is usually the product
+identifier - of the camera registered as "/dev/video0":
+
+ [root@localhost #] cd /sys/class/video4linux/video0
+ [root@localhost #] echo 1 > i2c_reg
+ [root@localhost #] cat i2c_val
+
+Note that if the sensor registers can not be read, "cat" will fail.
+To avoid race conditions, all the I/O accesses to the files are serialized.
+
+
+9. Supported devices
+====================
+None of the names of the companies as well as their products will be mentioned
+here. They have never collaborated with the author, so no advertising.
+
+From the point of view of a driver, what unambiguously identify a device are
+its vendor and product USB identifiers. Below is a list of known identifiers of
+devices mounting the ET61X[12]51 PC camera controllers:

+
+
+10. Notes for V4L2 application developers
+========================================
+This driver follows the V4L2 API specifications. In particular, it enforces two
+rules:
+
+- exactly one I/O method, either "mmap" or "read", is associated with each
+file descriptor. Once it is selected, the application must close and reopen the
+device to switch to the other I/O method;
+
+- although it is not mandatory, previously mapped buffer memory should always
+be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
+The same number of buffers as before will be allocated again to match the size
+of the new video frames, so you have to map the buffers again before any I/O
+attempts on them.
+
+Consistently with the hardware limits, this driver also supports image
+downscaling with arbitrary scaling factors from 1 and 2 in both directions.
+However, the V4L2 API specifications don't correctly define how the scaling
+factor can be chosen arbitrarily by the "negotiation" of the "source" and
+"target" rectangles. To work around this flaw, we have added the convention
+that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the
+scaling factor is restored to 1.
+
+This driver supports two different video formats: the first one is the "8-bit
+Sequential Bayer" format and can be used to obtain uncompressed video data
+from the device through the current I/O method, while the second one provides
+"raw" compressed video data (without frame headers not related to the
+compressed data). The current compression quality may vary from 0 to 1 and can
+be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP
+V4L2 ioctl's.

4. Overview and features
========================
-This driver attempts to support the video and audio streaming capabilities of
-the devices mounting the SONiX SN9C101, SN9C102 and SN9C103 PC Camera
-Controllers.
+This driver attempts to support the video interface of the devices mounting the
+SONiX SN9C101, SN9C102 and SN9C103 PC Camera Controllers.
It's worth to note that SONiX has never collaborated with the author during the
development of this project, despite several requests for enough detailed
- available mmap or read/poll methods for video streaming through isochronous
data transfers;
- automatic detection of image sensor;
+- support for built-in microphone interface;
- support for any window resolutions and optional panning within the maximum
pixel area of image sensor;
- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both
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
- your system supports hotplugging;
+ the system supports hotplugging;
- no known bugs.

8. Optional device control through "sysfs" [1]
==========================================
-It is possible to read and write both the SN9C10x and the image sensor
+If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
+it is possible to read and write both the SN9C10x and the image sensor
registers by using the "sysfs" filesystem interface.
Every time a supported device is recognized, a write-only file named "green" is
The sysfs interface also provides the "frame_header" entry, which exports the
frame header of the most recent requested and captured video frame. The header

controllers. As an example, this additional information can be used by the user
application for implementing auto-exposure features via software.

-10. How to add plug-in's for new image sensors
-==============================================
-It should be easy to write plug-in's for new sensors by using the small API
-that has been created for this purpose, which is present in "sn9c102_sensor.h"
-(documentation is included there). As an example, have a look at the code in
-"sn9c102_pas106b.c", which uses the mentioned interface.
-
-At the moment, possible unsupported image sensors are: CIS-VF10 (VGA),
-OV7620 (VGA), OV7630 (VGA).

The driver is divided into two modules: the basic one, "w9968cf", is needed for
the supported devices to work; the second one, "w9968cf-vpp", is an optional
module, which provides some useful video post-processing functions like video
-decoding, up-scaling and colour conversions. Once the driver is installed,
-every time an application tries to open a recognized device, "w9968cf" checks
-the presence of the "w9968cf-vpp" module and loads it automatically by default.
+decoding, up-scaling and colour conversions.
-Please keep in mind that official kernels do not include the second module for
-performance purposes. However it is always recommended to download and install
-the latest and complete release of the driver, replacing the existing one, if
-present: it will be still even possible not to load the "w9968cf-vpp" module at
-all, if you ever want to. Another important missing feature of the version in
-the official Linux 2.4 kernels is the writeable /proc filesystem interface.
+Note that the official kernels do neither include nor support the second
+module for performance purposes. Therefore, it is always recommended to
+download and install the latest and complete release of the driver,
+replacing the existing one, if present.
The latest and full-featured version of the W996[87]CF driver can be found at:
http://www.linux-projects.org. Please refer to the documentation included in
enabled for the 'ovcamchip' module to be loaded and for
this parameter to be present.
-------------------------------------------------------------------------------
-Name: vppmod_load
-Type: bool
-Syntax: <0|1>
-Description: Automatic 'w9968cf-vpp' module loading: 0 disabled, 1 enabled.
- If enabled, every time an application attempts to open a
- camera, 'insmod' searches for the video post-processing module
- in the system and loads it automatically (if present).
- The optional 'w9968cf-vpp' module adds extra image manipulation
- capabilities to the 'w9968cf' module,like software up-scaling,
- colour conversions and video decompression for very high frame
- rates.
-Default: 1
-Note: The kernel must be compiled with the CONFIG_KMOD option
- enabled for the 'w9968cf-vpp' module to be loaded and for
- this parameter to be present.
