Subject: [PATCH v1 07/25] PCI: xgene: Request host bridge window resources
Date: Mon, 06 Jun 2016 18:05:37 -0500 [thread overview]
Message-ID: <20160606230537.20936.2892.stgit@bhelgaas-glaptop2.roam.corp.google.com> (raw)
In-Reply-To: <20160606225630.20936.77349.stgit@bhelgaas-glaptop2.roam.corp.google.com>
Request host bridge window resources so they appear in ioport_resource and
iomem_resource and are reflected in /proc/ioports and /proc/iomem.
For example, the following entries did not previously appear in /proc/iomem:
e180000000-e1ffffffff : /soc/pcie@1f2b0000
e180000000-e182ffffff : PCI Bus 0000:01
e180000000-e181ffffff : 0000:01:00.0
e182000000-e1820fffff : 0000:01:00.0
e182100000-e1821fffff : 0000:01:00.0
f000000000-ffffffffff : /soc/pcie@1f2b0000
