[Barrelfish-users] ARM Build

Tue Jan 20 22:55:27 CET 2015

Hi,

Also note that we are currently testing our arm_gem5 build using a gem5 
version from November 2012 (revision 0fea324c832c from 
repo.gem5.org/gem5 to be exact). See tools/arm_gem5/README in the 
Barrelfish source tree for details on how we compile and use gem5 for armv7.

Best Regards,
-- Simon
