60 <para>For driver debugging purposes this ioctl allows test
61applications to query the driver about the chips present on the TV
62card. Regular applications must not use it. When you found a chip
63specific bug, please contact the linux-media mailing list (&v4l-ml;)
64so it can be fixed.</para>
65
66 <para>Additionally the Linux kernel must be compiled with the
67<constant>CONFIG_VIDEO_ADV_DEBUG</constant> option to enable this ioctl.</para>
68
69 <para>To query the driver applications must initialize the
70<structfield>match.type</structfield> and
71<structfield>match.addr</structfield> or <structfield>match.name</structfield>
72fields of a &v4l2-dbg-chip-info;
73and call <constant>VIDIOC_DBG_G_CHIP_INFO</constant> with a pointer to
74this structure. On success the driver stores information about the
75selected chip in the <structfield>name</structfield> and
76<structfield>flags</structfield> fields. On failure the structure
77remains unchanged.</para>
78
79 <para>When <structfield>match.type</structfield> is
80<constant>V4L2_CHIP_MATCH_BRIDGE</constant>,
81<structfield>match.addr</structfield> selects the nth bridge 'chip'
82on the TV card. You can enumerate all chips by starting at zero and
83incrementing <structfield>match.addr</structfield> by one until
84<constant>VIDIOC_DBG_G_CHIP_INFO</constant> fails with an &EINVAL;.
85The number zero always selects the bridge chip itself, &eg; the chip
86connected to the PCI or USB bus. Non-zero numbers identify specific
87parts of the bridge chip such as an AC97 register block.</para>
88
89 <para>When <structfield>match.type</structfield> is
90<constant>V4L2_CHIP_MATCH_SUBDEV</constant>,
91<structfield>match.addr</structfield> selects the nth sub-device. This
92allows you to enumerate over all sub-devices.</para>
93
94 <para>On success, the <structfield>name</structfield> field will
95contain a chip name and the <structfield>flags</structfield> field will
96contain <constant>V4L2_CHIP_FL_READABLE</constant> if the driver supports
97reading registers from the device or <constant>V4L2_CHIP_FL_WRITABLE</constant>
98if the driver supports writing registers to the device.</para>
99
100 <para>We recommended the <application>v4l2-dbg</application>
101utility over calling this ioctl directly. It is available from the
