<div dir="ltr">Hi,<div><br></div><div>I am trying to build kernel with v4l2 features enable.</div><div>I added these in my defconfig file (and necessary dependancy , and compile, </div><div><br></div><div><div>CONFIG_VIDEO_DEV=y</div>
</div><div>CONFIG_VIDEO_V4L2=y<br></div><div><br></div><div>I see those are included in the generated .config file, which is what I expected:</div><div><div>#</div><div># Multimedia core support</div><div>#</div><div>CONFIG_MEDIA_CAMERA_SUPPORT=y</div>
<div># CONFIG_MEDIA_ANALOG_TV_SUPPORT is not set</div><div># CONFIG_MEDIA_DIGITAL_TV_SUPPORT is not set</div><div># CONFIG_MEDIA_RADIO_SUPPORT is not set</div><div># CONFIG_MEDIA_RC_SUPPORT is not set</div><div># CONFIG_MEDIA_CONTROLLER is not set</div>
<div>CONFIG_VIDEO_DEV=y</div><div>CONFIG_VIDEO_V4L2=y</div><div>...</div></div><div><br></div><div>My problem is when I add CONFIG_VIDEOBUF2_CORE to my defconf, I don't that include in the generated .config file (the one that I mentioned above). </div>
<div>CONFIG_VIDEOBUF2_CORE=y<br></div><div><br></div><div>I have checked that CONFIG_VIDEOBUF2_CORE has no dependency. </div><div><a href="http://cateee.net/lkddb/web-lkddb/VIDEOBUF2_CORE.html">http://cateee.net/lkddb/web-lkddb/VIDEOBUF2_CORE.html</a><br>
</div><div><br></div><div>Hence , the causes my compilation fails.</div><div><br></div><div>Any one has any idea how to fix my problem?</div><div><br></div><div>Thank you.</div></div>
