From 9b81d556b11fe58827dcd87bc5deaf8da2f716ae Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 28 Oct 2016 13:58:50 +0100 Subject: [PATCH] drm/i915: Rename ->emit_request to ->emit_breadcrumb Now that the emission of the request tail and its submission to hardware are two separate steps, engine->emit_request() is confusing. engine->emit_request() is called to emit the breadcrumb commands for the request into the ring, name it such (engine->emit_breadcrumb).
