- Introduction
+
+ Thanks
- libATA is a library used inside the Linux kernel to support ATA host
- controllers and devices. libATA provides an ATA driver API, class
- transports for ATA and ATAPI devices, and SCSI<->ATA translation
- for ATA devices according to the T10 SAT specification.
+ The bulk of the ATA knowledge comes thanks to long conversations with
+ Andre Hedrick (www.linux-ide.org).
- This Guide documents the libATA driver API, library functions, library
- internals, and a couple sample ATA low-level drivers.
+ Thanks to Alan Cox for pointing out similarities
+ between SATA and SCSI, and in general for motivation to hack on
+ libata.
+
+
+ libata's device detection
+ method, ata_pio_devchk, and in general all the early probing was
+ based on extensive study of Hale Landis's probe/reset code in his
+ ATADRVR driver (www.ata-atapi.com).
libata Driver API
-
- struct ata_port_operations is defined for every low-level libata
- hardware driver, and it controls how the low-level driver
- interfaces with the ATA and SCSI layers.
-
-
- FIS-based drivers will hook into the system with ->qc_prep() and
- ->qc_issue() high-level hooks. Hardware which behaves in a manner
- similar to PCI IDE hardware may utilize several generic helpers,
- defining at a bare minimum the bus I/O addresses of the ATA shadow
- register blocks.

+
+
+8.12
+
+* Implement motorized pan/tilt feature for Logitech QuickCam Orbit/Spere.
+
+8.11.1
+
+* Fix for PCVC720/40, would not be able to set videomode
+* Fix for Samsung MPC models, appearantly they are based on a newer chipset
+
+8.11
+
+* 20 dev_hints (per request)
+* Hot unplugging should be better, no more dangling pointers or memory leaks
+* Added reserved Logitech webcam IDs
+* Device now remembers size & fps between close()/open()
+* Removed palette stuff altogether
+
+8.10.1
+
+* Added IDs for PCVC720K/40 and Creative Labs Webcam Pro
+
+8.10
+
+* Fixed ID for QuickCam Notebook pro
+* Added GREALSIZE ioctl() call
+* Fixed bug in case PWCX was not loaded and invalid size was set
+
+8.9
+
+* Merging with kernel 2.5.49
+* Adding IDs for QuickCam Zoom & QuickCam Notebook
+
+8.8
+
+* Fixing 'leds' parameter
+* Adding IDs for Logitech QuickCam Pro 4000
+* Making URB init/cleanup a little nicer
+
+8.7
+
+* Incorporating changes in ioctl() parameter passing
+* Also changes to URB mechanism
+
+8.6
+
+* Added ID's for Visionite VCS UM100 and UC300
+* Removed YUV420-interlaced palette altogether (was confusing)
+* Removed MIRROR stuff as it didn't work anyway
+* Fixed a problem with the 'leds' parameter (wouldn't blink)
+* Added ioctl()s for advanced features: 'extended' whitebalance ioctl()s,
+ CONTOUR, BACKLIGHT, FLICKER, DYNNOISE.
+* VIDIOCGCAP.name now contains real camera model name instead of
+ 'Philips xxx webcam'
+* Added PROBE ioctl (see previous point & API doc)
+
+8.5
+
+* Adding IDs for Creative Labs Webcam 5
+* Adding IDs for SOTEC CMS-001 webcam
+* Solving possible hang in VIDIOCSYNC when unplugging the cam
+* Forgot to return structure in VIDIOCPWCGAWB, oops
+* Time interval for the LEDs are now in milliseconds
+
+8.4
+
+* Fixing power_save option for Vesta range
+* Handling new error codes in ISOC callback
+* Adding dev_hint module parameter, to specify /dev/videoX device nodes
+
+8.3
+
+* Adding Samsung C10 and C30 cameras
+* Removing palette module parameter
+* Fixed typo in ID of QuickCam 3000 Pro
+* Adding LED settings (blinking while in use) for ToUCam cameras.
+* Turns LED off when camera is not in use.
+
+8.2
+
+* Making module more silent when trace = 0
+* Adding QuickCam 3000 Pro IDs
+* Chrominance control for the Vesta cameras
+* Hopefully fixed problems on machines with BIGMEM and > 1GB of RAM
+* Included Oliver Neukem's lock_kernel() patch
+* Allocates less memory for image buffers
+* Adds ioctl()s for the whitebalancing
+
+8.1
+
+* Adding support for 750
+* Adding V4L GAUDIO/SAUDIO/UNIT ioctl() calls
+
+8.0
+* 'damage control' after inclusion in 2.4.5.
+* Changed wait-queue mechanism in read/mmap/poll according to the book.
+* Included YUV420P palette.
+* Changed interface to decompressor module.
+* Cleaned up pwc structure a bit.
+
+7.0
+
+* Fixed bug in vcvt_420i_yuyv; extra variables on stack were misaligned.
+* There is now a clear error message when an image size is selected that
+ is only supported using the decompressor, and the decompressor isn't
+ loaded.
+* When the decompressor wasn't loaded, selecting large image size
+ would create skewed or double images.
+
+6.3
+
+* Introduced spinlocks for the buffer pointer manipulation; a number of
+ reports seem to suggest the down()/up() semaphores were the cause of
+ lockups, since they are not suitable for interrupt/user locking.
+* Separated decompressor and core code into 2 modules.
+
+6.2
+
+* Non-integral image sizes are now padded with gray or black.
+* Added SHUTTERSPEED ioctl().
+* Fixed buglet in VIDIOCPWCSAGC; the function would always return an error,
+ even though the call succeeded.
+* Added hotplug support for 2.4.*.
+* Memory: the 645/646 uses less memory now.
+
+6.1
+
+* VIDIOCSPICT returns -EINVAL with invalid palettes.
+* Added saturation control.
+* Split decompressors from rest.
+* Fixed bug that would reset the framerate to the default framerate if
+ the rate field was set to 0 (which is not what I intended, nl. do not
+ change the framerate!).
+* VIDIOCPWCSCQUAL (setting compression quality) now takes effect immediately.
+* Workaround for a bug in the 730 sensor.
