Conceptually, one replicates pieces that represent unshared hardware (CPU, memory, whatever) to give them all distinct names/types/connections. One challenge is configuring the non-hardware modules: those parts that relate to debugging, program loading, host I/O, scheduling. This can get complicated because of the number of degrees of freedom. It is simpler for a homogenous SMP system, where almost everything is shared. The public sid/bsp/configrun-sid script doesn't know how to construct such configurations automatically, but we have a newer C++-based configuration generator written by Graydon Hoare that does know how. If there is interest, we can try pushing it out to sourceware sooner rather than later. - FChE --/9DWx/yDrRhgMJTb Content-Type: application/pgp-signature Content-Disposition: inline Content-length: 232 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9idEtVZbdDOm/ZT0RAmSmAJ92K6Vu5GkRCxvrarqShz6u26a1WQCfa0Ap ngxXrc+A0Iemx6qHwfYG3ec= =WDtp -----END PGP SIGNATURE----- --/9DWx/yDrRhgMJTb--
