Subject: [PATCH v2 0/2] xen/arm: GICv3: Only initialize ITS when LPIs are available
Date: Wed, 24 Jan 2018 18:26:14 +0000 [thread overview]
Message-ID: <20180124182616.3384-1-julien.grall@linaro.org> (raw)
Hi all,
This small patch series fix an issue I discovered when using the Foundation
model and the DT provided by Linux upstream.
Indeed the Device-Tree is exposing an ITS but LPIs are not available.
Resulting to an early crash on Xen.
Whilst this looks a DT issue, Linux is able to cope with it. So I think Xen
should also cope with such DT.
Cheers,
