- </note>
-
- <para>For driver debugging purposes this ioctl allows test
-applications to query the driver about the chips present on the TV
-card. Regular applications must not use it. When you found a chip
-specific bug, please contact the linux-media mailing list (&v4l-ml;)
-so it can be fixed.</para>
-
- <para>To query the driver applications must initialize the
-<structfield>match.type</structfield> and
-<structfield>match.addr</structfield> or <structfield>match.name</structfield>
-fields of a &v4l2-dbg-chip-ident;
-and call <constant>VIDIOC_DBG_G_CHIP_IDENT</constant> with a pointer to
-this structure. On success the driver stores information about the
-selected chip in the <structfield>ident</structfield> and
-<structfield>revision</structfield> fields. On failure the structure
-remains unchanged.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_HOST</constant>,
-<structfield>match.addr</structfield> selects the nth non-&i2c; chip
-on the TV card. You can enumerate all chips by starting at zero and
-incrementing <structfield>match.addr</structfield> by one until
-<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.
-The number zero always selects the host chip, ⪚ the chip connected
-to the PCI or USB bus.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_I2C_DRIVER</constant>,
-<structfield>match.name</structfield> contains the I2C driver name.
-For instance
-<constant>"saa7127"</constant> will match any chip
-supported by the saa7127 driver, regardless of its &i2c; bus address.
-When multiple chips supported by the same driver are present, the
-ioctl will return <constant>V4L2_IDENT_AMBIGUOUS</constant> in the
-<structfield>ident</structfield> field.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_I2C_ADDR</constant>,
-<structfield>match.addr</structfield> selects a chip by its 7 bit
-&i2c; bus address.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_AC97</constant>,
-<structfield>match.addr</structfield> selects the nth AC97 chip
-on the TV card. You can enumerate all chips by starting at zero and
-incrementing <structfield>match.addr</structfield> by one until
-<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.</para>
-
- <para>On success, the <structfield>ident</structfield> field will
-contain a chip ID from the Linux
-<filename>media/v4l2-chip-ident.h</filename> header file, and the
-<structfield>revision</structfield> field will contain a driver
-specific value, or zero if no particular revision is associated with
-this chip.</para>
-
- <para>When the driver could not identify the selected chip,
-<structfield>ident</structfield> will contain
-<constant>V4L2_IDENT_UNKNOWN</constant>. When no chip matched
-the ioctl will succeed but the
-<structfield>ident</structfield> field will contain
-<constant>V4L2_IDENT_NONE</constant>. If multiple chips matched,
-<structfield>ident</structfield> will contain
-<constant>V4L2_IDENT_AMBIGUOUS</constant>. In all these cases the
-<structfield>revision</structfield> field remains unchanged.</para>
-
- <para>This ioctl is optional, not all drivers may support it. It
-was introduced in Linux 2.6.21, but the API was changed to the
-one described here in 2.6.29.</para>
-
- <para>We recommended the <application>v4l2-dbg</application>
-utility over calling this ioctl directly. It is available from the
-LinuxTV v4l-dvb repository; see <ulink
-url="http://linuxtv.org/repo/";>http://linuxtv.org/repo/</ulink> for
-access instructions.</para>
