I checked i915_trace.h and every tracepoint I added (intel_context class, i915_request_guc_submit) is protected by LOW_LEVEL_TRACEPOINTS. The only thing I changed outside of that protection is adding the guc_id field to existing i915_request class tracepoints. Without the guc_id in those tracepoints these are basically useless with GuC submission. We could revert that if it is a huge deal but as I said then they are useless...
