From: Manu Abraham To: Linux Kernel Mailing List , linux-pci@atrey.karlin.mff.cuni.cz, Grant Grundler Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi All, I have one of these PCIe switches on one of the PCIe cards that I have: http://www.plxtech.com/products/expresslane/pex8604 I was wondering how to handle this thing, ie; I have to PCIe devices behind this switch, which looks thus: 06:00.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba) 07:01.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba) 07:04.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba) 07:05.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba) 09:00.0 Multimedia controller: Philips Semiconductors Device 7231 (rev aa) 0a:00.0 Multimedia controller: Philips Semiconductors Device 7231 (rev aa) I am wondering if i need to access or address the switch specifically to forward data specifically to one of the bridges behind the switch. At present I can access one of the Multimedia controllers (09:00.0) , but it seems I can't access the other one and hence my question as to determine whether it is something else. Any pointer would be appreciated. Thanks, Manu
