From 58b77d4069823b44c5fa916fa8ddfc9c4cd51e02 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Wed, 24 Feb 2021 22:59:59 +0100 Subject: [PATCH] commands/setpci: Restrict setpci command when locked down This command can set PCI devices register values, which makes it dangerous in a locked down configuration. Restrict it so can't be used on this setup.
