This commit was manufactured to restore the state of the 3.3-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. $Id$ -> $FreeBSD$ 1999-08-29T15:57:45Z Peter Wemm peter@FreeBSD.org 1999-08-29T15:57:45Z urn:sha1:a92bee191d618605d749ddc8e410d0ae66d03752 Various changes to support OSF1 emulation: 1998-12-30T10:38:59Z Doug Rabson dfr@FreeBSD.org 1998-12-30T10:38:59Z urn:sha1:9c0fed3dcfd71bdd6c09a79a70b629db56c36e71 * Move the user stack from VM_MAXUSER_ADDRESS to a place below the 32bit boundary (needed to support 32bit OSF programs). This should also save one pagetable per process. * Add cvtqlsv to the set of instructions handled by the floating point software completion code. * Disable all floating point exceptions by default. * A minor change to execve to allow the OSF1 image activator to support dynamic loading. Major changes to the generic device framework for FreeBSD/alpha: 1998-06-14T13:46:10Z Doug Rabson dfr@FreeBSD.org 1998-06-14T13:46:10Z urn:sha1:99d11cde56ea2fb7b02c14ee57917b6b07f7ce35 * Eliminate bus_t and make it possible for all devices to have attached children. * Support dynamically extendable interfaces for drivers to replace both the function pointers in driver_t and bus_ops_t (which has been removed entirely. Two system defined interfaces have been defined, 'device' which is mandatory for all devices and 'bus' which is recommended for all devices which support attached children. * In addition, the alpha port defines two simple interfaces 'clock' for attaching various real time clocks to the system and 'mcclock' for the many different variations of mc146818 clocks which can be attached to different alpha platforms. This eliminates two more function pointer tables in favour of the generic method dispatch system provided by the device framework. Future device interfaces may include: * cdev and bdev interfaces for devfs to use in replacement for specfs and the fixed interfaces bdevsw and cdevsw. * scsi interface to replace struct scsi_adapter (not sure how this works in CAM but I imagine there is something similar there). * various tailored interfaces for different bus types such as pci, isa, pccard etc. Add initial support for the FreeBSD/alpha kernel.

Initial development and testing was done using SimOS (see http://simos.stanford.edu for details). On the SimOS simulator, this port successfully reaches single-user mode and has been tested with loads as high as one copy of /bin/ls :-).

These files don't necessarily make sense for a FreeBSD/Alpha kernel build. That will come later and these files will be changed accordingly.
