From 37fcd58ba6980222a5b51ea21ee266e5d34c04a2 Mon Sep 17 00:00:00 2001 From: Stefan Tauner Date: Tue, 10 May 2016 23:16:33 +0200 Subject: inteltool: handle unsafe dumping of graphics registers The current implementation from Vladimir simply dumps 1 MB of memory contents starting at the base address of the second PCI device (which most likely is the VGA controller on Intel systems). This locks up a number of different systems, e.g. my Ibex Peak-based T410s. This patch documents the issue and stops dumping the graphics registers for the -a/--all parameter.
