Subject: [Intel-gfx] [PATCH v4 04/18] drm/i915: Extract intel_mode_vblank_start()
Date: Wed, 13 Jan 2021 14:09:21 -0800 [thread overview]
Message-ID: <20210113220935.4151-5-manasi.d.navare@intel.com> (raw)
In-Reply-To: <20210113220935.4151-1-manasi.d.navare@intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
We want to calculate the vblank_start for vblank evasion
differently for vrr. To make that nicer lets first extract
the current non-vrr case to a helper.
