<pre>The last version just moved the check earlier. I doubt it made a difference to
your testing (though there is a very, very small chance it could cause a hang
of its own.)
Next I would test:
diff --git a/src/sna/sna_display.c b/src/sna/sna_display.c
index be02a78..20c67c9 100644
--- a/src/sna/sna_display.c
+++ b/src/sna/sna_display.c
@@ -3411,6 +3411,7 @@ static bool sna_emit_wait_for_scanline_hsw(struct sna

}
b[4] = MI_WAIT_FOR_EVENT | event;
+ sna->kgem.batch_flags |= I915_EXEC_SECURE;
return true;
}
