From 1dd7a3e7af70ebdd0cdd937b180726d15a4f0948 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 9 Aug 2017 13:07:02 -0700 Subject: [PATCH] drm/i915/cnl: Add slice and subslice information to debugfs. A missing part to EU slice power gating is the debugfs interface. This patch actually should have been squashed to the initial EU slice power gating one. v2: Initial patch was merged without this part. Fixes: c7ae7e9ab207 ("drm/i915/cnl: Configure EU slice power gating.")
