From c6d4a099a240a8742173f8e02db0ba08ffd37ef1 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 19 Dec 2019 17:56:52 +0200 Subject: [PATCH] drm/i915: reimplement header test feature 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 Cc: Chris Wilson Cc: Masahiro Yamada Signed-off-by: Masahiro Yamada Reviewed-by: Chris Wilson Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20191219155652.2666-3-jani.nikula@intel.com --- drivers/gpu/drm/i915/.gitignore | 1 + drivers/gpu/drm/i915/Makefile | 38 +++++++++++++++++++++++++++-------- drivers/gpu/drm/i915/display/Makefile | 6 ------ drivers/gpu/drm/i915/gem/Makefile | 5 ----- drivers/gpu/drm/i915/gt/Makefile | 5 ----- drivers/gpu/drm/i915/gt/uc/Makefile | 5 ----- drivers/gpu/drm/i915/oa/Makefile | 7 ------- 7 files changed, 31 insertions(+), 36 deletions(-) create mode 100644 drivers/gpu/drm/i915/.gitignore delete mode 100644 drivers/gpu/drm/i915/display/Makefile delete mode 100644 drivers/gpu/drm/i915/gem/Makefile delete mode 100644 drivers/gpu/drm/i915/gt/Makefile delete mode 100644 drivers/gpu/drm/i915/gt/uc/Makefile delete mode 100644 drivers/gpu/drm/i915/oa/Makefile diff --git a/drivers/gpu/drm/i915/.gitignore b/drivers/gpu/drm/i915/.gitignore new file mode 100644 index 000000000000..d9a77f3b59b2 --- /dev/null +++ b/drivers/gpu/drm/i915/.gitignore @@ -0,0 +1 @@ +*.hdrtest diff --git a/drivers/gpu/drm/i915/Makefile b/drivers/gpu/drm/i915/Makefile index b0c53661f62b..1a2fad832a4d 100644 --- a/drivers/gpu/drm/i915/Makefile +++ b/drivers/gpu/drm/i915/Makefile @@ -31,9 +31,6 @@ CFLAGS_display/intel_fbdev.o = $(call cc-disable-warning, override-init) subdir-ccflags-y += \ $(call as-instr,movntdqa (%eax)$(comma)%xmm0,-DCONFIG_AS_MOVNTDQA) -# Extra header tests -header-test-pattern-$(CONFIG_DRM_I915_WERROR) := *.h - subdir-ccflags-y += -I$(srctree)/$(src) # Please keep these build lists sorted!
