- stop using the evil 'struct trapframe' argument for mi_startup() (formerly main()). There are much better ways of doing it. - do not use prepare_usermode() - setregs() in execve() will do it all for us as long as the p_md.md_regs pointer is set. (which is now done in machdep.c rather than init_main.c. The Alpha port did it this way all along and is much cleaner). - collect all the magic %cr0 etc register settings into one place and have the AP's call that instead of using magic numbers (!!) that keep changing over and over again. - Make it safe to call kthread_create() earlier, including during the device probe sequence. It doesn't need the callback mechanism that NetBSD's version uses. - kthreads created this way are root-less as they exist before the root filesystem is mounted. init(1) is set up so that it aquires the root pointers prior to running. If other kthreads want filesystem acccess we can make this code more generic. - set all threads start times once we have decided what time it is. - init uses a trampoline rather than the evil prepare_usermode() hack. - kern_descrip.c has a couple of tweaks to deal with forking when there is no rootdir or cwd etc. - adjust the early SYSINIT() sequence so that a few prereqisites are in place. eg: make sure the run queue is initialized before doing forks. With this, the USB code can easily create a kthread to do the device tree discovery. (I have tested it, it works nicely). There are still some open issues before this is truely useful. - tsleep() does not like working before the clock is running. It sort-of tries to spin wait, but it can do more useful things now. - stopping a kthread in kld code at unload time is "interesting" but we have a solution for that. The Alpha code needs no changes for this. It already uses pretty much the same strategies, but a little cleaner. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
