+Subject: [PATCH] vulkan-samples: Fix reproducibility issue
+
+There is code to remove the prefix CMAKE_SOURCE_DIR from __FILENAME__ paths
+used for logging with LOGE() in the code. We need to make this match the value we use
+in the debug source remapping from CFLAGS
+
+We export the right path to use in the recipe with:
+
+EXTRA_OECMAKE = "-DCMAKE_DEBUG_SRCDIR=${TARGET_DBGSRC_DIR}/"
+
+and we then patch this into the code instead of the broken use
+of CMAKE_SOURCE_DIR since __FILENAME__ will match our path prefix
+changes.
+
+This also breaks reproducibility since the path length of the build directory
+will currently change the output!
+
+Upstream-Status: Pending [needs to be discussed upstream]
