From 0db18b17c8bca02638dcdc55dd458e04e18947b1 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 8 Dec 2017 01:23:00 +0000 Subject: [PATCH] drm/i915: Make engine state pretty-printer header configurable Pass in a format string (and args) to specify the header to be emitted along with the engine state when pretty-printing. This allows the header to be emitted inside the drm_printer stream, so sharing the same prefix and output characteristics (e.g. debug level and filtering).
