Hi,

Can someone provide any pointers on how to export kernel specific headers to userspace?

I am getting below error while building our one of the component which requires kernel uapi headers.

Error Received:
 /hdmi-capture/main.c:16:10: fatal error: linux/hdmi_info.h: No such file or directory
> |  #include <linux/hdmi_info.h>
> |           ^~~~~~~~~~~~~~~~~~~
> | compilation terminated.

In yocto 2.5, userspace is boot strapped with linux-libc-headers package which uses a set of uapi headers from Linux kernel 4.15. Can someone suggest for custom kernels, how to expose uapi headers to userspace? Thus create a separate linux-apl-headers package with those files.

Thanks,
Ankit
