Subject: [Intel-gfx] [PATCH 0/4] iommu/vt-d: Disable igfx iommu superpage on bxt/skl/glk
Date: Fri, 9 Jul 2021 19:47:46 +0300 [thread overview]
Message-ID: <20210709164750.9465-1-ville.syrjala@linux.intel.com> (raw)
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
I ran into some kind of fail with VT-d superpage on Geminlake igfx,
so without any better ideas let's just disable it.
Additionally Skylake/Broxton igfx have known issues with VT-d
superpage as well, so let's disable it there as well. This should
let us re-enable frame buffer compression (FBC) for some extra
power savings when the display is on.
