Subject: [Intel-gfx] [PATCH 16/18] drm/i915/guc: Update GuC debugfs to support new GuC
Date: Wed, 21 Jul 2021 14:50:59 -0700	[thread overview]
Message-ID: <20210721215101.139794-17-matthew.brost@intel.com> (raw)
In-Reply-To: <20210721215101.139794-1-matthew.brost@intel.com>

Update GuC debugfs to support the new GuC structures.

v2:
 (John Harrison)
  - Remove intel_lrc_reg.h include from i915_debugfs.c
 (Michal)
  - Rename GuC debugfs functions
