All of that makes sense and at least the stuff with the entry point should be changed, _if_ there would be a user. Switching operating modes is part of a reset instruction on s390: it resets everything: the whole I/O subsystem and the cpus. So switching processor operating modes makes a lot of sense to me, given all the problems seen with not properly reset devices seen on other architectures. If somebody really wants anything of the above, it could be changed, except for the restriction that the entry point must be below 2GB. _______________________________________________ fastboot mailing list [email protected] https://lists.osdl.org/mailman/listinfo/fastboot
