doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9) expect to be called with interrupts disabled, but shutdown hooks registered with pmf_device_register1(9) expect to be called with interrupts enabled. So I have made two changes: 1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead, change every call to doshutdownhooks() to a call to doshutdownhooks() followed by a call to pmf_system_shutdown(). No functional change is intended by this change. 2 Make i386 re-enable interrupts briefly while it calls pmf_system_shutdown(). I leave it to others either to fix the other ports, or to factor out some MI shutdown code, as joerg@ suggests, and fix that. Note that a functional change *is* intended by this change. I hope that this patch will stop us from flip-flopping between calling doshutdownhooks() and pmf_system_shutdown() sometimes with and sometimes without interrupts enabled. |

$NetBSD: README,v 1.3 2005/12/11 12:17:04 christos 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).
