History

ragge 4e254b7a82 Major rewriting, optimization and simplifying of the pmap code: - Map in all physical memory first in system space. This reduces pmap_copy_page() and pmap_zero_page to 3 resp. 2 instructions. - Have fized position user page tables. Makes the pv_table smaller and all reverse references faster (and simpler). - Remove the wiring code. Nobody doesn't even know what a DR32 is anymore. - Simulate page reference bit by setting page invalid, as suggested by Rich Draves in a paper for 1991 Mach Usenix Symposium. This reduced the time spent in the pmap module to between 70-75% of the previous; and made process startup _much_ faster.		1997-11-02 14:25:26 +00:00

README

	$NetBSD: README,v 1.10 1997/03/15 20:08:34 ragge Exp $

Devices supported in kernel and _known_ to work:
CPU:	VAX11/750, VAX11/78X, VAX86X0.
	MicroVAX II/III (MicroVAX 3200/3300/3400/3500/3600/3800/3900)
	VAXstation 2000/MicroVAX 2000.

Net:	DEUNA/DELUA Unibus ethernet cards.
	DEQNA/DELQA Q22 bus ethernet cards.
	LANCE ethernet.

Disks:	UDA50 Unibus MSCP controller.
	KDA50/RQDX3 Q22 bus MSCP controller.
		RA??-disks on UDA50 or KDA50.
		RD??-disks on RQDX3. (known as RA?? by system).
	RP??/RM?? disks on Massbus.
	RD?? disks on MFM ctlr.
	SCSI disks.

Tapes:	DILOG Q22 bus tape ctlr w/ Exabyte. (TMSCP emulating)
	TSV05 Q22 bus tape ctlr.
	SCSI tapes.
	TK50 (TMSCP) on Q22 bus.
		Other TMSCP ctlrs may also work, but haven't tried.


To install and run NetBSD/vax you need at least 4MB of memory,
and a usable install media. I can provide (on request) a kernel that
will netboot and run fine on standard 2MB VS2000.
Supported install media is TK50 tape and RX33/RX50 floppy, or over
the net. If you do initial installation from floppy then you need a way
to load the rest of the system, like tape or ethernet. 
NOTE! TU58 INSTALLATION IS NOT YET SUPPORTED.

Actually, the system will run fine on only 2MB of memory, but
installation program needs 4MB. If this causes trouble for someone
tell me and I'll fix it.

Differences between the NetBSD/vax port and other ports:
 * No dynamic linked libraries, all binaries is statically linked.
These things will be fixed in the future.


We who have done parts of the VAX port is:
	Joachim Isaksson, first pmap and lots of help with gcc functionality.
	Mattias Gr|nlund, locore assembler and interrupt handling.
	Mattias ]slund, lots of help and ideas everywhere.
	Bertram Barth, bootblocks and boot routines for MicroVAX.
	Rick Macklem, fixed all MicroVAX II, TMSCP and DEQNA support.
	Gunnar Helliesen is maintaining the NetBSD/VAX FAQ.
	Ken Wellsch wrote DHU11 driver and did kernel optimizations.
	Anders Magnusson (ragge), that's me, who put things together
		and wrote the rest.

Have fun with it,
