defined stubs in this header.

Several constant are also defined in the process.

The amdgpu DRM driver started to use them in Linux 6.12.x.

linuxkpi: Replicate Linux #includes between headers 2026-01-05T19:32:49+00:00 Jean-Sébastien Pédron dumbbell@FreeBSD.org 2025-08-17T11:17:49+00:00 b5f7a0b0fd8953c00b154d96b79ba0208c2e1aca The DRM drivers (and probably other parts of the Linux kernel) had a significant cleanup w.r.t. which source file includes what in Linux 6.10. Nonetheless, the DRM drivers still depend on implicit namespace pollution because some source files do not include all the headers they should. This cleanup broke the build with FreeBSD because we do not replicate the same `#include` directives everywhere. This commit adds the same `#include` directives in several headers in order to get the same namespace pollution. This fixes the build of the DRM drivers from Linux 6.10. An example is `drm_dp_tunnel.c` which needed `str_yes_no()` defined by <linux/string_helpers.h> (technically <linux/string_choices.h> in Linux). It gets it through: <linux/i2c.h> -> <linux/regulator/consumer.h> -> <linux/suspend.h> -> <linux/swap.h> -> <linux/memcontrol.h> -> <linux/cgroup.h> -> <linux/seq_file.h> -> <linux/string_helpers.h> Reviewed by: emaste Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D54496
