For our > situation that's a showstopper, unfortunately. It needs to be implemented the right way. Essentially this is a variation on the isolcpu kernel boot option. We probably need some syscall to move a user space process to a bare metal cpu since the cpu cannot be considered online in the regular sense. An isolated cpu can then only execute one process at a time. A process would do all initialization and lock itsresources in memory before going to the isolated processor. Any attempt to use OS facilities need to cause the process to be moved back to a cpu with OS services. -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
