<title>Introduction</title>
<para>
The bulk of the ATA knowledge comes thanks to long conversations with
Andre Hedrick (www.linux-ide.org).
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&lt;-&gt;ATA translation
for ATA devices according to the T10 SAT specification.
</para>
<para>
Thanks to Alan Cox for pointing out similarities
between SATA and SCSI, and in general for motivation to hack on
libata.
</para>
<para>
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).
This Guide documents the libATA driver API, library functions, library
internals, and a couple sample ATA low-level drivers.

<para>
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.
</para>
<para>
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.

8.4
* 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.
