I don't have a good idea where these headers are from. I'm only seeing that android's fork of the kernel had tda998x_ioctl.h at some point.
My guess is linux-headers installed it once upon a time and it got dropped.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=002612edc8b404763cfc8913f989fd887fb485d8 commit 002612edc8b404763cfc8913f989fd887fb485d8 Author: Alfred Wingate <parona@protonmail.com> AuthorDate: 2025-04-30 17:58:20 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2025-05-01 01:25:50 +0000 dev-libs/libcec: remove cubox use flag These headers may have never existed in the gentoo tree, older versions just silently compiled causing breakage elsewhere. Now the situation has improved in 7.0.0 where it will fail to configure without the headers present atleast. But this doesn't address the fact that these headers are still elusive. These headers were most likely available in an android fork of the kernel at some time and some other related headers are in an out of tree module beagle-nxp-hdmi which was last updated in 2012 and was never in the gentoo tree.
