Subject: [Intel-gfx] [PATCH v2 09/11] drm/i915: Implement async flip for ivb/hsw
Date: Mon, 11 Jan 2021 18:37:09 +0200 [thread overview]
Message-ID: <20210111163711.12913-10-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20210111163711.12913-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Add support for async flips on ivb/hsw. Unlike bdw+ we don't need
any workarounds to disable async flips. Apart from that the only
real difference from the bdw implementation is the location of the
flip_done interrupt bits.
