So I also added the support for handling undefined macros as the IS_ENABLED() counterpart. However the feedback received from Masahiro Yamada was that it is too ugly, not providing much value. And just wrapping in a boolean context is too dumb - we could simply open code it. As detailed in commit babaab2f4738 ("drm/i915: Encapsulate kconfig constant values inside boolean predicates"), the IS_ACTIVE macro was added to workaround a compilation warning. However after checking again our current uses of IS_ACTIVE it turned out there is only 1 case in which it would potentially trigger a warning. All the others can simply use the shorter version, without wrapping it in any macro. And even that single one didn't trigger any warning in gcc 10.3. So here I'm dialing all the way back to simply removing the macro. If it triggers warnings in future we may change the few cases to check for > 0 or != 0. Another possibility would be to use the great "not not operator" for all positive checks, which would allow us to maintain consistency. However let's try first the simplest form though, hopefully we don't hit broken compilers spitting a warning: Signed-off-by: Lucas De Marchi --- drivers/gpu/drm/i915/gem/i915_gem_context.c | 2 +- drivers/gpu/drm/i915/gem/i915_gem_mman.c | 2 +- drivers/gpu/drm/i915/gt/intel_engine.h | 4 ++-- drivers/gpu/drm/i915/gt/intel_engine_heartbeat.c | 2 +- drivers/gpu/drm/i915/gt/intel_engine_types.h | 2 +- .../gpu/drm/i915/gt/intel_execlists_submission.c | 2 +- .../gpu/drm/i915/gt/selftest_engine_heartbeat.c | 4 ++-- drivers/gpu/drm/i915/gt/selftest_execlists.c | 14 +++++++------- drivers/gpu/drm/i915/i915_config.c | 2 +- drivers/gpu/drm/i915/i915_request.c | 2 +- drivers/gpu/drm/i915/i915_utils.h | 13 ------------- 11 files changed, 18 insertions(+), 31 deletions(-) diff --git a/drivers/gpu/drm/i915/gem/i915_gem_context.c b/drivers/gpu/drm/i915/gem/i915_gem_context.c index 8208fd5b72c3..be60bcf8069c 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_context.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_context.c @@ -761,7 +761,7 @@ static int intel_context_set_gem(struct intel_context *ce, intel_engine_has_semaphores(ce->engine)) __set_bit(CONTEXT_USE_SEMAPHORES, &ce->flags);
