1.1 deraadt 20:
1.4 fn 21: <p>
1.1 deraadt 22: The early history is not very clear. Apparently the first work was
23: done by CMU as part of their Mach project. The initial hardware was
24: the DEC R2000/R3000-based Decstations. This code was later used by
25: both the Sprite and BSD groups. The 4.4BSD code, known as the `pmax'
26: port, was made freely available in mid '93. It was merged into the
27: NetBSD tree by a variety of people, but has never been very stable,
28: reliable, or complete. Compiler toolkit problems have plagued the
29: port because the standard a.out executable format is an imperfect
30: match to the MIPS architecture.

1.1 deraadt 34: Per Fogelstrom became familiar with the code after porting it to a
35: home-built IDT R3081 based board. Subsequently he added R4400 support
36: when porting it to the MIPS R4400 Acer PICA board. Willowglen
37: Singapore purchased a second PICA board for Theo de Raadt so that he
38: could improve the port for use as a development system for an internal
1.4 fn 39: project. Since then Theo and Per have had ethernet and a few other
1.1 deraadt 40: small projects working.
1.4 fn 41: </p>
1.1 deraadt 42:
43: <p>
44: The Acer PICA is a dead platform. Acer no longer makes the machine,
45: but even worse the machines are very rare. The main reason to work on
46: this port is because there are a multitude of other MIPS-based
1.5 ! deraadt 47: machines -- eventually (very soon) this code will be useful on another
! 48: machine.

52: The people working the most on OpenBSD/pica currently consists of
1.4 fn 53: Per Fogelstrom, and Theo de Raadt. Of course, others are very welcome!

! 57: Recent developments:
! 58: <ul>
! 59: <li>ELF shared libraries throughout
! 60: <li>ELF executables that page in, unlike NetBSD where they are
! 61: read into memory.
! 62: <li>Almost native build. Very soon all the utilities needed will be in the
! 63: source tree.
! 64: <li>nlist() function that understands a.out, ELF, or ecoff binaries.
! 65: <li>The kvm utilities work.
