Subject: [PATCH 12/13] PCI: Only treat non-pref mmio64 as pref if host bridge has mmio64
Date: Thu, 20 Apr 2017 22:04:59 -0700 [thread overview]
Message-ID: <20170421050500.13957-13-yinghai@kernel.org> (raw)
In-Reply-To: <20170421050500.13957-1-yinghai@kernel.org>
If host bridge does not have mmio64 above 4G, We don't need to
treat device non-pref mmio64 as as pref mmio64.
