I've been trying to get systemsim-gpul working with the latest Xen-PPC. The last changeset that worked was 7ad4645e7a54 (11/22/06). Changeset ce8c1e26b2ae (Early boot memory avoidance improvemnts) broke the simulator with the 'Could not allocate RTAS tree' / HANG error. With changeset

2007-01-04 Thread Michal Ostrowski
Could be that midway through a Linux boot all code is sequential, but at a later point Linux tries to initialize its timing facilities. This involves linux spinning on the timebase register which forces systemsim to simulate many, many useless cycles. Beyond that Linux initialization sees a lot
