The DRM subsystem contains additional build-time checks, primarily aimed at DRM developers and CI systems. The checks may be overzealous. They may slow down or fail the build altogether. They may create excessive dependency files in the build tree. They should not be enabled for regular builds, and certainly not forced on unsuspecting developers running an allyesconfig or allmodconfig build. Add config DRM_DISABLE_EXTRA_BUILD_CHECKS, enabled by default as well as by allyesconfig/allmodconfig, hiding the extra checks from anyone but people who intentionally opt-in for the checks. For example, to enable header tests: $ scripts/config --disable CONFIG_DRM_DISABLE_EXTRA_BUILD_CHECKS --enable CONFIG_DRM_HEADER_TEST $ make olddefconfig Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Closes: https://lore.kernel.org/r/CAHk-=wjcdfrDTjzm6J6T-3fxtVyBG7a_0BXc2=mgOuM6KPFnCg@mail.gmail.com Fixes: 62ae45687e43 ("drm: ensure drm headers are self-contained and pass kernel-doc") Cc: Masahiro Yamada <masahiroy@kernel.org> Cc: David Airlie <airlied@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> --- Cc: linux-kbuild@vger.kernel.org Cc: dri-devel@lists.freedesktop.org Cc: intel-xe@lists.freedesktop.org Cc: intel-gfx@lists.freedesktop.org --- drivers/gpu/drm/Kconfig | 21 +++++++++++++++++++-- 1 file changed, 19 insertions(+), 2 deletions(-)
