From 87bc7e64dab51e2627fa8b2536d9c3218b8f75e7 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 17 May 2013 13:48:19 -0600 Subject: [PATCH] lspci: Fully decode ASPM support from Link Capabilities The ASPM Support field in Link Capabilities is two bits, and all four possible encodings are defined as of PCIe spec r3.0. Previously, lspci only decoded values 1, 2, and 3. This adds 0, so lspci will show "ASPM not supported" instead of "ASPM unknown".
