kqueue provides a stateful and efficient event notification framework currently supported events include socket, file, directory, fifo, pipe, tty and device changes, and monitoring of processes and signals kqueue is supported by all writable filesystems in NetBSD tree (with exception of Coda) and all device drivers supporting poll(2) based on work done by Jonathan Lemon for FreeBSD initial NetBSD port done by Luke Mewburn and Jason Thorpe |

$NetBSD: README,v 1.1 2001/05/14 18:22:58 drochner Exp $ This is a port of NetBSD to the FIC8234 VME processor board, made by the swiss company CES (Geneve). These boards are (or have been) popular in high energy physics data acquisition (think of CERN!). See http://www.ces.ch/Products/CPUs/FIC8234/FIC8234.html for some technical data. The highlights: - MC68040 processor at 25 MHz (optional dual-processor) - 8 or 32 MByte RAM - 2 serial ports on Z85c30 - 79c900 (ILACC) ethernet - 53c710 SCSI The port is quite rudimentary at the moment. The kernel is started out of a running OS-9 system. SCSI support is not present yet, so it only works diskless with NFS (or ramdisk - not tested) root. It is good enough for multiuser, self-hosting etc. however. To start it: - make OS image by "objcopy --output-target=binary netbsd <imagename>" - load image to physical address 0x20100000 (RAM start + 1M) - jump to 0x20100400 For questions and contributions, contact Matthias Drochner (drochner@netbsd.org).
