I have been an active
more than 15 years.
Most of the work I've done has ended up being commited to the master repository.
However, incomplete or unpolished works may sometimes be found here until they are ready to hit the tree. You'll find also some tips and other random bits, and sometimes experimental kernels for some platforms.
For the curious people out there, here is a short (and incomplete) list of my OpenBSD achievements:
- Added Alpha DS15/DS25/ES45 (Titan) system family support, as well as
environmental exception handling (chassis alarms) to the
Files: mainly sys/arch/alpha/alpha/dec_6600.c, sys/arch/alpha/include/logout.h
- Ported to AViiON systems.
a driver for HP Audio1 device, found on HP 9000/425e (only
audio-capable hp300 system) and
various early PA-RISC systems.
Files: sys/dev/ic/arcofi.c, sys/dev/ic/arcofivar.h, and the attachments interfaces sys/arch/hp300/dev/arcofi_dio.c for hp300 and sys/arch/hppa/gsc/arcofi_gsc.c for hppa.
bus support to the hp300 port.

a driver for the Tigershark PersonalVRX
hp300 frame buffer.
a driver for the Apollo keyboard and mouse, used by the

- Rewrote the
subsystem for the
port. This subsystem is also used by the
Files: sys/arch/hp300/dev/hil_intio.c, sys/arch/hppa/gsc/hil_gsc.c, everything in sys/dev/hil/
a driver for the PS/2 keyboard and mouse port found on most
Files: sys/arch/hppa/gsc/gsckbc.c, sys/arch/hppa/gsc/gsckbcreg.h
to be able to switch console path in the hppa port bootloader
(allowing models 712 to be configured for serial console despite the PROM
not allowing this).
- Ported to the Lemote Fuloong, Lynloong and Yeelong systems, as well as the
Dexxon Gdium Liberty
Files: about everything in sys/arch/loongson/

a driver for the MVME327 SCSI controller for the
Files: sys/arch/mvme68k/dev/vsbic.c, sys/arch/mvme88k/dev/vsbic.c (they are almost identical and were supposed to eventually merge)
- Added multiprocessor support (SMP) to the mvme88k port.
- Fixed the mvme88k port codebase to run reliably on 88110-based systems.
- Ported to the Octane and Origin/Onyx families of Silicon Graphics
workstations and servers (including Fuel and Tezro) (part of the
This required writing several specific device drivers

- Designed and implemented a low-overhead workaround for R4000 infamous
end-of-page errata, allowing SGI Indigo (and some early Indy) to run
Files: mainly sys/arch/mips64/mips64/r4000_errata.c, which comments detail the design and implementation.
- Wrote drivers for many SPARC SBus frame buffers, such as Fujitsu AG-10e
Southland Media Systems MGX/MGX+
Parallax XVideo and PowerVideo
used by the
