exceptions from both kernel and user mode. * Fix context switching so that we can switch back to a proc which we switched away from (we were saving the state in the wrong place). * Implement lazy switching of the high-fp state. This needs to be looked at again for SMP to cope with the case of a process migrating from one processor to another while it has the high-fp state. * Make setregs() work properly. I still think this should be called cpu_exec() or something. * Various other minor fixes. With this lot, we can execve() /sbin/init and we get all the way up to its first syscall. At that point, we stop because syscall handling is not done yet. |
