Notes about the NetBSD integration
|
|
|
|
|
----------------------------------

|
Preface and Acknowledgements:
|
|
|
|
|
|
|
|
|
|
A first try at integrating the M68060 Software Package was done by
|
|
|
|
|
Yasushi Yamasaki of the NetBSD/x68k group, but only available as a
|
|
|
|
|
patch file to their source tree (which wasn't integrated into the
|
|
|
|
|
NetBSD master tree at that time).
|
|
|
|
|
|
|
|
|
|
I started with their glue code version from the patch file, and
|
|
|
|
|
changed the following things up to now:
|
|
|
|
|
|
|
|
|
|
- collapse a few identical glue routines (fetch code/data words/longs
|
|
|
|
|
from user space) into a multi-labeled one
|
|
|
|
|
|
|
|
|
|
- make the gas syntax files of the glue code the Master files
|
|
|
|
|
|
1999-02-23 01:07:37 +03:00
|
|
|
- translate the gas syntax files of the Motorola code once, to avoid
|
|
|
|
|
the translation time.
|
|
|
|
|
|
1996-05-16 01:06:18 +04:00
|
|
|
- I call the access error handler (label _buserr) directly, instead of
|
|
|
|
|
through an RTE as in the example file
|
|
|
|
|
|
|
|
|
|
Other changes are only in the method this was integrated into the
|
|
|
|
|
Amiga vs. X68k port, which is machine dependend anyway.
|
|
|
|
|
|
|
|
|
|
Thanks for the initial effort!

I. File suffix convention
|
|
|
|
|
|
|
|
|
|
I cvs imported all of the Motorola files (with lowercase names).
|
2000-04-15 00:24:29 +04:00
|
|
|
These have been moved to the dist subdirectory as of today --- 2000-04-14
|
1996-05-16 01:06:18 +04:00
|
|
|
|
|
|
|
|
These are:
|
|
|
|
|
|
|
|
|
|
*.s: Assembler files "unsupported by Motorola, provided as a reference only"
|
|
|
|
|
*.sa: Pseudo assembler hex dump files, which is Motorolas supported version.
|
|
|
|
|
*.doc: docs by Motorola
|
|
|
|
|
|
|
|
|
|
errata, changes, files, readme: by Motorola.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
I choose .S as the file suffix which is feeded to our assembler
|
|
|
|
|
directly or indirectly.
|
|
|
|
|
|
|
|
|
|
We use: To create:
|
|
|
|
|
|
|
|
|
|
isp.sa isp.S
|
|
|
|
|
fpsp.sa fpsp.S
|
|
|
|
|
|
2000-04-15 00:24:29 +04:00
|
|
|
Type "make" in this directory to create them, then check in.
|
|
|
|
|
|
1996-05-16 01:06:18 +04:00
|
|
|
In addition, inetbsd.S and fnetbsd.S are our part specific glue files,
|
|
|
|
|
netbsd.S is our general glue file, and copyright.S ensures we have a
|
|
|
|
|
copy of the copyright notice in the kernel if using the 060SP.
|
|
|
|
|
|
|
|
|
|
To enforce the right relative positions of isp/its glue code inetbsd.S
|
|
|
|
|
includes isp.S at the end, and fnetbsd.S includes fpsp.S.
|
|
|
|
|
|
|
|
|
|
Ia: Don't Change Files
|
|
|
|
|
|
|
|
|
|
- all Motorola doc files, all .sa (hex) files.
|
|
|
|
|
|
|
|
|
|
Ib: Nearly Don't Change Files
|
|
|
|
|
|
|
|
|
|
- for now, the .s files by Motorola. We might use the fpsp.s file
|
|
|
|
|
later to create an optimized version, once we a) verified its
|
|
|
|
|
identical to the supported .s and b) write a conversion (to .S format)
|
|
|
|
|
script.
|
|
|
|
|
|
|
|
|
|
II. Interface to the arch/$machine/$machine files:
