* Implement the long-awaited module->file cache database. A userlandPeter Wemm2001-09-111-3/+2
| | | | | | | | | | tool (kldxref(8)) keeps a cache of what modules and versions are inside what .ko files. I have tested this on both Alpha and i386. Submitted by: bp Notes: svn path=/head/; revision=83321

* Fix autoboot. Now autoboot *always* show the correct kernel name. ItDaniel C. Sobral2000-09-081-17/+36
| | | | | | | | | | | | | | | | | | | | | gets the name from the environment variable kernelname, which is set when a kernel is loaded. For this reason, autoboot will _first_ try to load a kernel, and only proceed with the wait prompt after that succeeds. If it fails, it will abort immediately. While I understand some may think this behavior undesirable, I think it is, overall, the best thing to do, even if we do not consider the aesthetic issue. Notice that anyone using the default loader.rc already has the kernel loaded before autoboot. On unload, unset kernelname. Separate the code that tries to load a kernel from the list of options to the function loadakernel(). It is used by both boot() and autoboot(). Notes: svn path=/head/; revision=65613

* Delay calling the device cleanup routines until the absolute lastPaul Saab2000-06-141-5/+0

* The loader was written so that if /kernel was missing /kernel.old wouldDavid E. O'Brien2000-05-131-0/+2
| | | | | | | | | | | be booted. Due to a bug, this wasn't happening. There is still a lesser bug in that the loader decides which file to boot after the 10sec count down. This means the bootfile listed in the count down in is wrong in the case where the loader will boot /kernel.old. Notes: svn path=/head/; revision=60490
* Update loader logic to distinguish modules vs. files.Boris Popov2000-05-011-8/+8

* - VERBOSE_LS is obsolete, as the heap is much better behaved now.Mike Smith1998-10-071-8/+30
| | | | | | | | | | | | | | | | | | - Don't whine about nodes we can't stat(); these are usually symlinks that lead out of the filesystem. - Autoboot is now controlled by $autoboot_delay, which is a value in seconds or NO to disable autoboot. - Don't autoboot at the end of boot.conf if we have already tried. - Add a 'read' command to complement 'echo'. Both are still hidden. - Improve the 'source' command/function so that it is possible to source scripts off removable media. The entire script is read and saved before beginning execution. Script lines beginning with '@' will not be echoed when being executed. Script execution will normally terminate at the first error, however if the script line begins with '-' this behaviour is overriden for that command. Notes: svn path=/head/; revision=40015

* Bootloader update.Mike Smith1998-08-311-2/+4
| | | | | | | | | | | | | | | - Implement a new copyin/readin interface for loading modules. This allows the module loaders to become MI, reducing code duplication. - Simplify the search for an image activator for the loaded kernel. - Use the common module management code for all module metadata. - Add an 'unload' command that throws everything away. - Move the a.out module loader to MI code, add support for a.out kld modules.

* This is the new unified bootstrap, sometimes known previously as theMike Smith1998-08-211-0/+229
'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
