d14a472e3c BIOS manufacturers don't seem to have a unique idea about 2.88 MB
floppy drive types in the CMOS; add 0x50 as an alias for 2.88 MB.

73cb54f1d4 Fix tracing of syscalls. The previous fix required the undocumented
option DDB_NO_LCALLS to stop ddb getting control and broke all ddb
tracing.  Now there is no option and no way for ddb to trace at
address _Xsyscall or to _Xsyscall, but tracing everywhere else
works.  The previous fix did unnecessary things for Linux syscalls.

Don't bother checking that syscall frames are for user mode.

Make debugger traps inside the kernel (except at addresses _Xsyscall
and _Xsyscall+1) fatal if ddb is not configured.  They "can't happen".

Add prototypes.

Remove stupid comments, e.g., /*ARGSUSED*/ for args that are used.

0f62a1bc92 Identify the 2940 *Ultra* SCSI adapter. We treat it as a normal 2940
for now since I don't have any documentation on this card yet and it
is software compatible with the earlier cards.

The 2940 *Ultra* is Adaptec's push to take SCSI to 20MHz bus rates.  Its
based on the aic7880 chip which is the successor to the aic7870.

f89a2d2259 Remove prototype definitions from <sys/systm.h>.
Prototypes are located in <sys/sysproto.h>.

Add appropriate #include <sys/sysproto.h> to files that needed
protos from systm.h.

Add structure definitions to appropriate files that relied on sys/systm.h,
right before system call definition, as in the rest of the kernel source.

In kern_prot.c, instead of using the dummy structure "args", create
individual dummy structures named <syscall>_args.  This makes
life easier for prototype generation.

f6c446557e Remove compat_43 psuedo-argument hack, and replace with a better hack.
Instead of using a fake "compat" argument, pass a real compat int to function
if COMPAT_43 is defined.  Functions involved: wait4, accept, recvfrom,
getsockname.

With the compat psuedo-argument, this introduces an argument structure
that can have two possible sizes depending on compat options.
This makes life difficult for lkm modules like ibcs2, which would
have to guess what size used in kernel when compiled.  Also,
the prototype generator for these structures cannot generate proper sizes.

Now there is only one fixed structure and makes everybody happy.

I recommend these changes be introduced to 2.1 so that ibcs2, linux
lkm's generated for 2.2 can still run on a 2.1 kernel.

11b88f454b Remake generated files to reflect makesyscalls.sh changes 1995-10-07 06:29:30 +00:00
swallace
9c1e10e65e Add new functionality to makesyscalls.sh:
o  optional config-file to set vars: sysnames, sysproto, sysproto_h,
	syshdr, syssw, syshide, syscallprefix, switchname, namesname, sysvec.
  o  change syntax of syscalls.master entry:
	remove argument count.
	add pseudo-prototype field defining function name and arguments.
  o  generates correct structure definitions for all system calls
	in sys/sysproto.h
  o  add type NOARGS:  same as STD except do not create structure in
	sys/sysproto.h
  o  add type NOPROTO:  same as STD except do not create structure or function
	prototype in sys/sysproto.h

New functionality provides complete prototype definitions.
Usefull for generating files for emulated systems like my new ibcs2 code.

Update syscalls.master to reflect new changes.  For example, read()
entry now looks like:

3	STD	POSIX	{ int ibcs2_read(int fd, char *buf, u_int nbytes); }

This is similar to how NetBSD generates these files.

91aa19bcd7 Convert ARP to use queue.h macros rather than insque/remque. While
we're at it, eliminate obsolete exposure of `struct llinfo_arp' to
the world.  (This dates back to when ARP entries were not stored in
the routing table, and there was no other way for the `arp' program
to read the whole table than to grovel around in /dev/kmem.)

f12a489cee Fix pollution of application namespace by declarations of kernel
functions.  The application header <sys/user.h> includes <vm/vm.h>
which includes <vm/lock.h>...

vm.h:
Don't include <machine/cpufunc.h>.  It is already included by
<sys/systm.h> in the kernel and isn't designed to be included by
applications (the 2.1 version causes a syntax error in C++ and the
current version has initializers that are invalid in strict C++).

lock.h:
Only declare kernel functions if KERNEL is defined.

31218d9591 Don't wait for output to drain in pppclose(). Discard output immediately
for the same reasons as in slclose().

Free the cblock in the canonical queue in pppclose().  This is a no-op in
the usual cases where the tty is being closed or the line discipline is
being switched back to the standard discipline, but it saves a cblock if
the line discipline is being switched to one that doesn't use the canonical
queue.

Add prototypes.  I use `extern' in prototypes for functions with bogus
linkage.  This should be fixed someday.

Continue cleaning up new init stuff yet again.

and here is the patch.  Submit it please. Thank you!

BTW, there is a new option "NDGBPORTS". By default it is equal to
NDGB*16 and means the number of ports of all Digiboards for which the
tty structures are reserved. It can be set to the real value in config-file
like:

       options "NDGBPORTS=8"

306caafb86 Make a whole bunch of PCB variables ints rather than shorts. There appear
to be no ill effects, and so far as Iknow none of the variables in
question depend on 16-bit wraparound behavior.  (The sizes are in
many cases relics from when a PCB had to fit inside a 128-byte mbuf.  PCBs
are no longer stored in that way, and the old structure would not have
fit, either.)

368d81d28d find some way of letting a node know where in its parent's directory structure
it was referenced from.. stops a rather annoying panic, but
introduces a rather interesting but "I can live with it" bug
`ln a b ; mv a b; echo ?`
returns a rather than b..

ec8963af8a Make swapgeneric.c compile and (sort of) work again.
This is really just a token gesture at this point. We can't really turn
on swapping here anymore because (I think) we need to do a namei() lookup
in order to get a vnode which we can pass to swaponvp(). But to do a
namei(), we need a properly initialized proc structure, and we don't
have one. (I was hopping to toss it proc0, but that isn't initialized
until later.) We could conceiveably fabricate a dummy proc structure
to make namei() happy, but that's too much work for too little payoff.

For now, swapgeneric's only remaining saving grace is that it lets
you set the root device with -a.
