1.20 niklas 21: The alpha port was derived from the NetBSD/alpha port written by Chris
1.41 espie 22: Demetriou <cgd@netbsd.org>. Unfortunately we cannot track it closely
23: anymore as some copyright issues prevent us, check our
24: <a href=policy.html>policy</a> page for details.
25: There have been a few efforts to keep this port modern,
1.22 deraadt 26: which also includes many userland 64 bit problems which we have tracked down
1.29 deraadt 27: and made fixes to. Many of the improvements mentioned below are not found
28: in NetBSD, but you should do your own research to decide which those are.
1.14 niklas 29: <p>
30: Initially the reason for existence of this port was to provide the OpenBSD
31: operating system to alpha users, i.e. no special effort was put in to develop
32: the port in the machine dependent parts. The main thing that got done was to
1.17 niklas 33: ensure that all the tools needed to build a full system was included in the
34: tree, as well as updated with the changes Chris distributed in a separate
35: alpha toolchain package.
1.13 niklas 36: <p>
1.41 espie 37: Today, more developers have alpha machines, and we are seeing interest in
38: a more active port, but there still is very little active development going
39: on. This fact has so far led to:
1.24 niklas 40: <ul>
1.29 deraadt 41: <li>A large-scale attack at fixing remaining 64-bit 'long' vs 'int'
42: problems in the entire userland source tree. Most of these
43: have been fixed, and new 64-bit problems are only rarely found.
1.38 johns 44: <li>Adaptation of the if_ed ethernet driver.
1.41 espie 45: <li>Parsing of i386 MBR & disklabels.
1.27 deraadt 46: <li>DDB (kernel debugger) (disassembler, tracebacks, single stepping).
1.41 espie 47: <li>IDE & ATAPI support.
1.24 niklas 48: <li>Easy installation via floppy.
1.30 kstailey 49: <li>Fixed VGA workstation console driver. Added "stand-out" (highlight) to it too.
1.24 niklas 50: </ul>
1.35 deraadt 51: <h3><font color=#0000e0><strong>Projects (in no particular order):</strong></font></h3>
1.24 niklas 52: <ul>
53: <li>ISA DMA (enables many common PC peripherals to be used)
54: <li>floppy support (requires ISA DMA).
55: <li>ELF object file format (gives shared libs)
1.41 espie 56: <li>egcs fixes for the Ramdisk
1.24 niklas 57: </ul>

1.12 niklas 59: So far <a href="http://www.appli.se/niklas/">Niklas Hallqvist</a>
60: <a href=mailto:niklas@openbsd.org><niklas@openbsd.org></a> has been
1.41 espie 61: trying to keep the port alive, but despite more people having alpha,
62: the port is barely alive and not too actively maintained.
