Subject: [Qemu-devel] [PATCH v3 10/26] pcie: pass pcie window size to pcie_host_mmcfg_update()
Date: Fri, 19 Oct 2012 16:43:32 -0400	[thread overview]
Message-ID: <24b7d8736b55f284b13990be93dcdfd06d471cfc.1350677361.git.jbaron@redhat.com> (raw)
In-Reply-To: <cover.1350677360.git.jbaron@redhat.com>

From: Jason Baron <jbaron@redhat.com>

This allows q35 to pass/set the size of the pcie window in its update routine.
