From bf9cc891d32b1c784bcd4d181321bb279254bdf8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 22 Jan 2020 12:41:54 +0000 Subject: [PATCH] drm/i915/gt: Include a tell-tale for engine parking We have two trace messages that rely on the function name for distinction. However, if gcc inlines the function, the two traces end up with the same function name and are indistinguishable. Add a different message to each to clarify which one we hit, i.e. which phase of engine parking we are processing.
