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.
