Subject: [PATCH] drm/i915: prevent generating unusable gvt build which no mpt module is selected
Date: Wed, 24 May 2017 16:50:39 +0800 [thread overview]
Message-ID: <1495615839-20797-1-git-send-email-changbin.du@intel.com> (raw)
From: Changbin Du <changbin.du@intel.com>
At least we need one MPT module (currently only have one) selected
to get GVTg functional. When GVTg is enabled while no MPT selected,
the build just includes useless GVTg code. This doesn't make sense.
With this patch, a submenut is created under i915 as below:
-*- Enable Intel GVT-g graphics virtualization host support
<M> Enable KVM/VFIO support for Intel GVT-g
If no MPT is selected, GVTg will be disabled automatically.
< > Enable KVM/VFIO support for Intel GVT-g

Choose this option if you want to enable Intel GVT-g graphics
virtualization technology host support with integrated graphics.
With GVT-g, it's possible to have one integrated graphics
