File 0029-linux-user-Fake-proc-cpuinfo.patch.patch of Package qemu
From e67665b1e48f881de79a8ce8811c4acc732e5e92 Mon Sep 17 00:00:00 2001 From: Alexander Graf <agraf@suse.de> Date: Mon, 23 Jul 2012 10:24:14 +0200 Subject: [PATCH] linux-user: Fake /proc/cpuinfo Fedora 17 for ARM reads /proc/cpuinfo and fails if it doesn't contain ARM related contents. This patch implements a quick hack to expose real /proc/cpuinfo data taken from a real world machine. The real fix would be to generate at least the flags automatically based on the selected CPU. Please do not submit this patch upstream until this has happened.
