Subject: Is PCI express Gen 2 supported by Linux?
To: linux-kernel@vger.kernel.org
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

I've scanned the PCI information under Documentation/PCI in the source tree, but could not find this information. I am not sure if PCIe gen 2 requires special software support in the PCI layer, or if the hardware hides any PCIe version differences from the Linux PCI driver.

Thanks,
Andrei
