sys/arch/amiga tree. This is the machdep part required to get the kernel
up on an A3000. There are still (very) few changes required outside the arch/amiga tree, so you can't recompile the kernel yet. Support for third party SCSI controllers for the A2000 is on its way. The kernel is fully functional (except for a missing ethernet-driver ...). This tree is based on my version #390.

The HP300 version uses a kernel which is loaded into the range 0xfffxxx... but
|
||||
is linked for range 0x000.. This causes the problem that with switching the
|
||||
MMU to the mapped kernel, the PC becomes invalid. The HP version solves the
|
||||
problem by mapping 1:1 the last page of physical memory into virtual memory.
|
||||
|
||||
On the Amiga, there *is* memory at PA 0x0, so we might as well use it, causes
|
||||
much less grief and weirdness in locore.s. However, since memory down there
|
||||
is CHIPMEM, inherently slower than FASTMEM, and badly needed for framebuffer
|
||||
storage space, we'll copy the kernel over to the first bank of FASTRAM, and
|
||||
when enabling the MMU, the kernel will execute in FASTRAM, although the PC
|
||||
stays the same.
|
||||
|
||||
This strategy has the big advantage (compared to the solution in Amiga MACH)
|
||||
that we can link the kernel absolutely to VA 0, for all memory models, since
|
||||
we'll never execute the kernel in the FASTMEM space while the MMU is turned
|
||||
off.
|
||||
|
||||
This strategy also means, that we don't have to relocate any addresses while
|
||||
bootstrapping the mmu!!
|
||||
|
||||
Initialization of the MMU happens in amiga_init.c. This file is quite a mess,
|
||||
I have generated it trying to understand what's happening in the hp300 locore.s
|
||||
file. I think, it should be able to handle MMU initialization much cleaner
|
||||
now that we don't have to think about relocation until the MMU is enabled.
|
||||
If you need your daily bit of horror, take a look at amiga_init.c...

Current list as of 93-7-5:

|

Those I'm aware of:
|

- nfsd and mountd crash regularly when going to multiuser mode...
|

- the console seems to have some problems displaying text when parity is
|
||||
enabled. This shows in a distorted login-prompt (multiuser mode).
|

- the vt200 emulator is really far from perfect, and needs a lot more work
|
||||
to be honestly called a vt200 (or vt320 even) emulator.
|
||||
- the console chops the rightmost character, I guess this is a problem of
|

the display-window, not of the bitmap drawing itself.
|
||||
- 8bit characters are all displayed as ^@. Problems could lie in wrong tty
|

settings or the ite driver.
|

- although autoconfig information is passed into the kernel and the hardware
|

table is generated, no I/O-space is currently allocated in kernel VM for
|
||||
boards. This will probably be one of the first things to fix or nobody is
|
||||
able to access their boards under BSD ...
|
||||
- sun-style disklabels are not yet supported.
|
||||
- disklabels can't be written back to disk. You'll have to configure your
|
||||
drives under amigados (with hdtoolbox), and just format the partitions
|
||||
under BSD. I think this is a tolerable limitation.
|
||||
- there's currently no provision for reading the realtime-clock, so time

is always set using the last modification date of the mounted root

- severe crash after dumping to disk...

How to install BSD on your Amiga:
|
||||
--------------------------------
|
||||
|
||||
*Please* (re)read the README.amiga file, and make sure your system is
|
||||
supported by the current kernel.
|
||||
|
||||
Since BSD doesn't yet have a floppy driver, and you'll need a root fs
|
||||
to start using commands (chicken and egg problem..) to make your own
|
||||
fs, installation of the root fs is a bit hacky...
|
||||
|
||||
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
|
||||
> We copy a binary image (8M) of the root fs directly to the place on <
|
||||
> your harddisk. This is an extremely dangerous thing to do, since if <
|
||||
> you get the offsets wrong, you'll destroy data on other partitions of <
|
||||
> the drive! <
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
If you don't feel like risking the life of innocent data on your disk,
|
||||
better stop installing now, and wait until installation gets safer in
|
||||
the future!!!
|
||||
|
||||
|
||||
Ok.. if you're reading on, start up hdtoolbox, and create some partitions
|
||||
for use by BSD. You'll have to at least create two partitions:
|
||||
|
||||
o a root partition:
|
||||
Must have FileSystem: Custom File System
|
||||
Identifier: 0x42534452 (`BSDR')
|
||||
Reserved begin: 0
|
||||
end: 0
|
||||
Use custom boot code: NO (ie. no checkmark)
|
||||
FS block size: 512
|
||||
You don't have to check Automount, the partition could only
|
||||
confuse AmigaDOS.
|
||||
|
||||
o a swap partition:
|
||||
Must have FileSystem: Custom File System
|
||||
Identifier: 0x42534453 (`BSDS')
|
||||
Reserved begin: 0
|
||||
end: 0
|
||||
Use custom boot code: NO (ie. no checkmark)
|
||||
FS block size: 512
|
||||
You don't have to check Automount, the partition could only
|
||||
confuse AmigaDOS.
|
||||
|
||||
|
||||
You might also add a /usr partition, for example on BSDD:
|
||||
Must have FileSystem: Custom File System
|
||||
Identifier: 0x42534444 (`BSDD')
|
||||
Reserved begin: 0
|
||||
end: 0
|
||||
Use custom boot code: NO (ie. no checkmark)
|
||||
FS block size: 512
|
||||
You don't have to check Automount, the partition might only
|
||||
confuse AmigaDOS.
|
||||
|
||||
|
||||
Other settings (like MaxTransfer and Mask) are ignored.
|
||||
|
||||
Now, you'll have to find out about the exact block start address and length
|
||||
in blocks of the BSDR fs (BSD will find out about the data of the other
|
||||
partitions once it's started up). Go into "Change Drive Type" menu, and
|
||||
write down the "Blocks per Cylinder" value it shows you for this drive. Then
|
||||
go into the "Partition Drive" menu, select your BSDR partition, enable
|
||||
"Advanced Options", and write down the "Start Cyl" and "End Cyl" values.
|
||||
|
||||
Doing "Blocks per Cylinder" * "Start Cyl" gives you the block start number
|
||||
of the BSDR partition, doing "Blocks per Cylinder" * ("End Cyl" - "Start Cyl")
|
||||
results in the length of the partition in blocks. You'll need these values
|
||||
to install the root fs onto the drive, so please write them down, and PLEASE
|
||||
make sure you calculated them right, since if not, you'll scribble anywhere
|
||||
on the drive, and that just might be.. (insert worst imaginations..).
|
||||
|
||||
**************************************************************************
|
||||
The rootfs has a length of ~8M, 16448 blocks. Your root fs must have at
|
||||
least (!) the same amount of blocks. You don't have to make it exactly
|
||||
16448 blocks though, a task that could even be impossible if the number of
|
||||
blocks per cylinder on your drive is not a divisor of 16448.
|
||||
**************************************************************************
|
||||
|
||||
Now you're almost ready to do the installation. Unzip the distributed rootfs.gz
|
||||
file (you'll need 8M of free space on your amigados partition for this!), and
|
||||
then do:
|
||||
|
||||
filetodev {START_NUMBER} 16448 rootfs scsi.device {UNIT} 1000
|
||||
|
||||
with:
|
||||
{START_NUMBER}: above calculated block start number
|
||||
{UNIT}: the scsi unit you're installing on, 0-6
|
||||
|
||||
|
||||
The filetodev program is included in the bffs11.lzh archive, and was written
|
||||
by Chris Hooper (cdh@mtu.edu).
|
||||
|
||||
|
||||
|
||||
How to start BSD
|
||||
----------------
|
||||
|
||||
You start BSD with a loader program from AmigaDOS. This loader is called
|
||||
`loadbsd', and it takes as parameter the kernel file, normally vmunix.
|
||||
|
||||
So,
|
||||
|
||||
loadbsd vmunix
|
||||
|
||||
will (try to...) boot BSD. The kernel as distributed prefers to boot from
|
||||
SCSI unit 6. It will probably boot from other units as well (can't test
|
||||
this at the moment, since I don't want to repartition my other drives). If
|
||||
you run into problems (ie. BSD says it can't mount the root filesystem),
|
||||
you'll have to recompile the kernel. Please see the RECOMPILE file for
|
||||
how to do this.
|
||||
|
||||
|
||||
What about /usr ?
|
||||
-----------------
|
||||
For the first distribution of the kernel, I decided not to distribute
|
||||
binaries for the /usr filesystem. Simply, because /usr is huge compared
|
||||
to root, and a.out headers are likely to change in the future, rendering
|
||||
a distributed /usr filesystem almost useless.

Here's the initial version of NetBSD for the Amiga. This version is strictly

for the kernel hackers among you, there's no sense in `normal' users trying
|

to install it, possibly killing their other partitions, facing kernel panics and
|

not knowing what to do. Please keep that in mind, if you feel like going on...

Currently supported equipment:
|
||||
-----------------------------
|
||||
|
||||
o any Amiga with either 68020/68851 or 68030, 6888[12] is currently required
|
||||
(because fpu code is conditionally compilable in the kernel, and this
|
||||
version contains fpu code).
|
||||
o A3000 internal SCSI controller. Note that you cannot boot BSD currently
|
||||
with any other SCSI controller (not to mention weird IDE interfaces..).
|
||||
o internal RS232 port. This is not by default used as the system console.
|
||||
you have to recompile if you want the console on the RS232.
|
||||
o some `sort of' VT200 emulator for the custom chips display, which is
|
||||
an NTSC laced, 640x400 monochrome display. This is the default console.
|
||||
o disk and tape drivers using the mentioned A3000 scsi controller.
|
||||
Disks I tried it on include: Wren7, IBM-OEM 0663E12, Quantum LP105S.
|
||||
Only tape tested is my Wangtek 5150ES.
|
||||
|
||||
|
||||
Some comments on these:
|
||||
----------------------
|
||||
68020&68851/68030 support:
|
||||
These cpu's should be fully supported. Note that you cannot run
|
||||
BSD with a '30EC, the MMU is absolutely required. The '40 is
|
||||
currently *NOT* supported, don't try! The reason for this is
|
||||
the braindamaged, mind boggingly stupid '40 MMU, which only
|
||||
implements a very limited subset of the 68851/68030 MMUs. In
|
||||
particular, it doesn't deal with the current 2-level MMU
|
||||
setup. See the extra doc about AMIGA-MMU for details.
|
||||
Exception handling for the '40 is also different to its predecessors,
|
||||
however this should be easier to implement than revamping
|
||||
the MMU code to work on the '40.
|
||||
|
||||
A3000 internal SCSI controller:
|
||||
This is a driver tested on an AMD33C93A chip, I just hope I
|
||||
didn't do anything that won't run on the dreadful WD33C93A-PROTO
|
||||
still in use in thousands of A3000. It is a *VERY* rough
|
||||
driver, it's really a hack, and should be replaced by a chip-
|
||||
specific low-level driver for use with the generic scsi/*
|
||||
code for the PC. Might even use Mach-drivers as well. The
|
||||
driver would support DMA, if only DMA would work... That is,
|
||||
DMA trashed my memory, so I disabled it for a while, and the
|
||||
driver was degraded to a PIO in the meanwhile.. Hope to get
|
||||
DMA up again RSN ...
|
||||
Note that (contrary to Amiga Unix..) this driver should handle
|
||||
drives ok that send sync-requests (it just rejects those..).
|
||||
|
||||
Internal RS232 port:
|
||||
Well, that's not exactly a terribly complicated thing.. It should
|
||||
perform reasonably well, but I didn't really test it with file
|
||||
transfers, just with my old VT100. It should do hardware flow-
|
||||
control, but that's not tested either. The driver supports being
|
||||
a console.
|
||||
|
||||
Custom chips display, console:
|
||||
I implemented the console in a two-layer approach stolen from
|
||||
the hp300 implementation. There is a low-level layer (grf*)
|
||||
responsible for creating a display (`view' in AmigaOS parlance),
|
||||
and a hi-level layer (ite*) dealing with display of characters,
|
||||
scrolling regions, handling keyboard, etc. This approach should
|
||||
it make trivial to support consoles on custom graphics boards.
|
||||
Grf currently opens an interlaced NTSC screen, with a resolution
|
||||
of 1024x1024 pixels, and a visible display size of 640x400. It
|
||||
provides for smooth scrolling of this display window inside the
|
||||
larger bitmap (once the ioctl's are implemented..), and it can
|
||||
handle overscan (by changing the visible display size and moving
|
||||
the display offset). These ioctl's aren't implemented yet either.
|
||||
Oh: don't try to convince me to offer a PAL display, I won't.
|
||||
The console tries to be some sort of VT200 compatible terminal,
|
||||
however, I only implemented a small subset of features. Essentially,
|
||||
I took the existing HP-ite driver, a VT320 manual, and started
|
||||
to replace the control sequences with the ones I found in the
|
||||
manual. Don't expect the driver to do downloadable fonts or other
|
||||
weird features, I think even scrolling regions might be broken
|
||||
at the moment. It should however work reasonably well for most
|
||||
editing purposes.
|
||||
|
||||
|
||||
Keyboard:
|
||||
Default keymap is US-ASCII. However, I reasoned quite a bit about
|
||||
how to do the mapping of keys into characters and character
|
||||
sequences to easily change the keymap to international layouts.
|
||||
Dead-keys are supported, as well as having a second set of keys
|
||||
reachable with the Alt keys (same usage as AmigaOS). Thus, you
|
||||
should be able to generate an ö (oe) by typing Alt-k o.
|
||||
However, currently any 8bit characters just appear as ^@ on the
|
||||
screen, and I don't know whether the tty is responsible for this
|
||||
misfeature, or whether I have a bug in my alt-key handling...
|
||||
All keys sending <CSI> sequences send <CSI> as <ESC>[ instead of
|
||||
\x9b, as under AmigaOS. This should make use with Emacs, Bash, etc.
|
||||
*much* easier.
|
||||
For information about how keymaps work, look at dev/kbdmap.h and
|
||||
dev/kbdmap.c.
|
||||
|
||||
Disks:
|
||||
See the special section on how RDBs map into BSD partitions.
|
||||
|
||||
Tapes:
|
||||
The tape driver seems to support a variety of different tape
|
||||
drives. Chances are, your tape will work too. Just give it a try,
|
||||
worst thing that can happen is a kernel panic ;-)
|
||||
|
||||
|
||||
|
||||
RDB's and how BSD finds its partitions on disk drives
|
||||
-----------------------------------------------------
|
||||
BSD partition tables usually look like this:
|
||||
A: boot partition, ~8M
|
||||
B: swap partition, twice the (Fast)RAM size you have
|
||||
C: the entire disk
|
||||
D: /usr
|
||||
E, F, G, H: additional partitions
|
||||
|
||||
Since Amiga partitions are managed thru a RigidDiskBlock (RDB) stored
|
||||
in the first cylinder(s) of a drive, I took the following approach to
|
||||
map Amiga partitions to BSD A-H partitions:
|
||||
|
||||
C: still is the entire disk. Take extreme care!!
|
||||
A: has identifier: BSDR (Root fs)
|
||||
B: has identifier: BSDS (Swap fs)
|
||||
DEFGH: have identifiers: BSDD, BSDE, BSDF, BSDG, BSDH.
|
||||
|
||||
BSD recognizes at most one partition of each type per drive, but you can
|
||||
have multiple BSDD partitions on different drives, for example.
|
||||
|
||||
There is no restriction on the volume name for those partitions, and
|
||||
there's no restriction on the order of the partitions on the disk, you can
|
||||
have BSDD before BSDR, for example.
|
||||
|
||||
-> IMPORTANT NOTE: BSD will boot off the last BSDR partition it finds,
|
||||
ie. if you have a BSDR partition on drives 0 and 6,
|
||||
it will boot from the one in drive 6 !!
|
||||
|
||||
I'm running BSD on my Amiga with BSDR, BSDS, BSDE on drive 6, and a
|
||||
BSDD on drive 1. BSDD on drive 6 is a backup root filesystem, I can just
|
||||
change its type to BSDR, change the BSDR type to BSDD (ie. swap them), and
|
||||
boot off the other partition, without BSD noticing anything.
|
||||
|
||||
|
||||
Using UFS partitions formatted under Amiga Unix System V Release 4
|
||||
------------------------------------------------------------------
|
||||
You can use such partitions under NetBSD-Amiga, however, you cannot use
|
||||
partitions formatted (newfs/mkfs) under NetBSD-Amiga under Amix. Amix
|
||||
uses the old BSD-4.2 ffs, and doesn't understand the new BSD-4.3 ffs.
|
||||
|
||||
|
||||
Other documents
|
||||
---------------
|
||||
The BSD distribution contains a huge doc directory, so if you want to
|
||||
know everything about XYZ, chances are you'll find a manual for it there.
|
||||
The other short docs in this distribution cover:
|
||||
|
||||
AMIGA-MMU: short description of what's going on when initializing
|
||||
the system.
|
||||
|
||||
BUGS: you might guess what this contains :-)
|
||||
|
||||
INSTALL: quick guide on how to install the included dump of the
|
||||
root filesystem on your harddisk. This is quite risky,
|
||||
please read the warnings, and only try the installation
|
||||
if you feel totally confident that you understood the
|
||||
process!
|
||||
|
||||
README.first: this file.
|
||||
|
||||
RECOMPILE: short notes about how to change the default configuration
|
||||
(throw out unneeded drivers, add drivers for other
|
||||
SCSI units, etc). Recompiling probably requires a lot
|
||||
of experience in this sort of things (possibly from already
|
||||
hacking around with the Mach kernel...), I'd imagine
|
||||
make'ing the kernel requires a lot of unix'ish tools
|
||||
not commonly found on `normal' amigas, however you
|
||||
should find most of them in the Mach distribution.
|
||||
|
||||
|
||||
Distribution of NetBSD-Amiga
|
||||
----------------------------
|
||||
I'll try to put my updates on ftp.eunet.ch, given that I don't run out
|
||||
of diskspace there. After integrating the Amiga changes into the official
|
||||
NetBSD sources, you'll also be able to get the (entire) distribution
|
||||
from sun-lamp.cs.berkeley.edu, or any of its mirrors. I'm using the
|
||||
NetBSD-current sources, and am updating my source tree regularly, however I
|
||||
didn't incorporate the most recent changes before the first release, since
|
||||
I've worked with this version for some time now, and found it to be
|
||||
fairly stable (so no loadable kernel modules yet in this release).
|
||||
|
||||
There is going to be a mailing-list for NetBSD-Amiga, I'll post the
|
||||
information to comp.unix.amiga when I know its definite name and location.
|
||||
|
||||
You can reach me at mw@eunet.ch, please mention `BSD' in your Subject:
|
||||
line, this makes it easier for me to automatically sort incoming mail
|
||||
according to topic, thanks!

How to recompile (under AmigaDOS)
|
||||
---------------------------------
|
||||
|
||||
You need a fairly complete unix programming environment. You also need
|
||||
gcc, I don't think any of the commercial compilers could recompile the
|
||||
kernel. The central configuration directory is sys/arch/amiga/conf. CD
|
||||
there, and take a look at the file AMIGA. Things you might change in
|
||||
this file are:
|
||||
|
||||
timezone: change to your timezone.
|
||||
|
||||
options: comment out modules you don't need, to make the kernel
|
||||
smaller. Good candidates for exclusion are probably
|
||||
the ISOFS (CD filesystem), ISO and TPIP (implement OSI
|
||||
sockets). PCFS is entirely untested, so you might
|
||||
get rid of it as well.
|
||||
|
||||
config: this is a vital line, it tells BSD where to find the
|
||||
root filesystem and the swap partition. The device
|
||||
name is composed of `sd', which is the disk driver,
|
||||
the unit number (6 in the distributed file), and the
|
||||
partition (A==root).
|
||||
|
||||
disk: make sure there's an entry for your SCSI unit, the
|
||||
kernel as distributed supports drives at units 0, 1 and
|
||||
6.
|
||||
|
||||
tape: if you don't have a tape drive, you can remove those
|
||||
entries, and save some space in the kernel.
|
||||
|
||||
pseudo-device: you can safely remove `sl' and `bpfilter', please don't
|
||||
remove `ite', or you'll end up without a console...
|
||||
|
||||
|
||||
When you're happy with the config file, you have to run it thru the
|
||||
config program. config is included in the bin directory of this
|
||||
distribution, together with the loader. In sys/arch/amiga/conf, do
|
||||
|
||||
config AMIGA
|
||||
|
||||
After a moment, config reminds you to do a make depend, well, you can't,
|
||||
there's no mkdep at the moment;-) Just make sure all object files of
|
||||
previous runs are removed, then `make', and cross fingers. The make
|
||||
process will need some binaries found in the bin directory of this
|
||||
distribution, so add bin to your PATH before starting the compilation.
|
||||
|
||||
The distributed console bitmap font is *UGLY*. I'd strongly suggest
|
||||
you CD to sys/arch/amiga/stand/dumpfont, and generate a new font source
|
||||
file containing the topaz.font of AmigaOS. This looks *much* nicer
|
||||
than the free Mach font, but since it is part of AmigaOS, it is
|
||||
owned by Commodore, and may not be redistributed, you'll have to regenerate
|
||||
it, sorry. Dumpfont will output a new source file to stdout. Redirect
|
||||
this output to a file, and then copy it to sys/arch/amiga/dev/kernel_font.c.
|
||||
If you can't get dumpfont working on your system (or if you're
|
||||
crosscompiling from a non-amiga system), copy the ugly
|
||||
sys/arch/amiga/dev/kernel_font.c.distrib to sys/arch/amiga/dev/kernel_font.c
|
||||
instead.
|
||||
|
||||
If you run into problems recompiling, configuring, etc. first try to
|
||||
find a solution yourself. I would prefer to work on BSD than to answer
|
||||
tons of email, but if you're really stuck, you can reach me at mw@eunet.ch.
