Subject: [Intel-gfx] [PATCH v11 11/12] drm/i915: Add bigjoiner aware plane clipping checks
Date: Wed, 21 Oct 2020 22:42:22 -0700	[thread overview]
Message-ID: <20201022054223.25071-12-manasi.d.navare@intel.com> (raw)
In-Reply-To: <20201022054223.25071-1-manasi.d.navare@intel.com>

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

We need to look at hw.fb for the framebuffer, and add the translation
for the slave_plane_state. With these changes we set the correct
rectangle on the bigjoiner slave, and don't set incorrect
src/dst/visibility on the slave plane.

v2:
* Manual rebase (Manasi)

v3:
* hw.rotation instead of uapi.rotation (Ville)
