Subject: [PATCH] drm/i915/display: Disable casf with joiner
Date: Mon, 5 Jan 2026 14:42:02 +0530 [thread overview]
Message-ID: <20260105091202.203926-1-nemesa.garg@intel.com> (raw)
Currently pipe scaling is not supported with the
joiner. As casf requires pipe scaling, fail the
atomic commit whenever joiner comes into picture.
