* Major changes to the generic device framework for FreeBSD/alpha:Doug Rabson1998-06-141-11/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. Notes: svn path=/head/; revision=36972
* Add initial support for the FreeBSD/alpha kernel. This is very much aDoug Rabson1998-06-101-0/+41
work in progress and has never booted a real machine. 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 :-).
