Subject: [Intel-gfx] [PATCH 3/3] drm/i915: reimplement header test feature
Date: Thu, 19 Dec 2019 17:56:52 +0200	[thread overview]
Message-ID: <20191219155652.2666-3-jani.nikula@intel.com> (raw)
In-Reply-To: <20191219155652.2666-1-jani.nikula@intel.com>

From: Masahiro Yamada <yamada.masahiro@socionext.com>

I implemented a small build rule in drivers/gpu/drm/i915/Makefile
without relying on the special header-test-y syntax that was removed in
commit fcbb8461fd23 ("kbuild: remove header compile test").

I excluded some headers from the test coverage. I hope somebody
intrested can take a closer look at them.

Dummy subdir Makefiles can be removed altogether as single target build
use case is now covered by commit 394053f4a4b3 ("kbuild: make single
targets work more correctly").

v2 by Jani:
- add selftests/i915_perf_selftests.h to no-header-test
- add .gitignore for *.hdrtest
