Subject: [Intel-gfx] [PATCH 17/23] drm/i915: Get the uapi state from the correct plane when bigjoiner is used
Date: Sat, 14 Nov 2020 00:03:52 +0200	[thread overview]
Message-ID: <20201113220358.24794-18-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20201113220358.24794-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

When using bigjoiner userspace is only controlling the "master"
plane, so use its uapi state for the "slave" plane as well.

hw.crtc needs a bit of magic since we don't want to copy that from
the uapi state (as it points to the wrong pipe for the "slave
" plane). Instead we pass the right crtc in explicitly but only
assign it when the uapi state indicates the plane to be logically
enabled (ie. uapi.crtc != NULL).
