I believe you need to do it in the .c file:

Can you try something like this?

diff --git a/drivers/gpu/drm/i915/i915_trace_points.c b/drivers/gpu/drm/i915/i915_trace_points.c

-#ifndef __CHECKER__
+#if !DEFINED(__CHECKER__) && !DEFINED(CONFIG_PREEMPT_RT)
 #define CREATE_TRACE_POINTS
 #include "i915_trace.h"
 #endif


Or is it just that one set of trace events that is an issue?

Could you just do:

#if defined(CONFIG_DRM_I915_LOW_LEVEL_TRACEPOINTS) && !defined(CONFIG_PREEMPT_RT)

 ?
