[Qemu-devel] [PULL v2 2/9] linux-user: add pseudo /proc/hardware for m68

From: Laurent Vivier
Subject: [Qemu-devel] [PULL v2 2/9] linux-user: add pseudo /proc/hardware for m68k
Date: Fri, 24 May 2019 13:25:13 +0200

Debian console-setup uses /proc/hardware to guess the keyboard layout.
If the file /proc/hardware cannot be opened, the installation fails.

This patch adds a pseudo /proc/hardware file to report the model of
the machine. Instead of reporting a known and fake model, it
reports "qemu-m68k", which is true, and avoids to set the configuration
for an Amiga/Apple/Atari and let the user to chose the good one.
