Subject: [PATCH 4/4] drm/i915/tgl: Report valid VDBoxes with SFC capability
Date: Tue, 30 Jul 2019 17:49:02 -0700 [thread overview]
Message-ID: <20190731004902.34672-5-daniele.ceraolospurio@intel.com> (raw)
In-Reply-To: <20190731004902.34672-1-daniele.ceraolospurio@intel.com>
From: Michel Thierry <michel.thierry@intel.com>
In Gen11, only even numbered "logical" VDBoxes are hooked up to a SFC
(Scaler & Format Converter) unit. This is not the case in Tigerlake,
where each VDBox can access a SFC.
We will use this information to decide when the SFC units need to be reset
and also pass it to the GuC.
Bspec: 48077
