Back out the changes in the previous revision. Function-like macros
were replaced by compound statements that work in less contexts.
Unoformize idempotency #ifdef.
Restore the simple leap year calculation as a macro and document it so
that it doesn't become complicated again. The simple version works
for all leap years covered by 32-bit time_t's. The complicated version
doesn't work for all leap years covered by 64-bit time_t's since among
other reasons, the solar system is not stable for long enough.
Fix declarations.
Nuke spinwait().
"gcc -Wstrict-prototypes" doesn't emit warnings about them.
Write each min/max functions on a single line so that the similarity and
triviality of the functions is more obvious.
Put the quad min/max functions in the correct place (aphabetical order).
The u_quad min/max functions are missing. Only 3 or 4 of the min/max
functions are actually used. sys/socketvar.h ``should use "lmin" but
it doesn't exist now''. lmin does exist now, but isn't used. Since we
depend on gcc for `inline', perhaps we should depend on it for __typeof
and function-expressions and use only macros min() and max() that work
for any types (I'm not sure how to handle mixed types).
actually used.
Remove "#ifdef __GNUC__" around some __dead* declarations. __dead* is
harmless if __GNUC__ is not defined.
Uniformize idempotency #ifdef.
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example). A few significant differences:
1) ntp_gettime() is now a MIB variable rather than a system call. A few
fiddles are done in libc to make it behave the same.
2) mono_time does not participate in the PLL adjustments.
3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime(). Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.
is used instead of /usr/lib
io.c: add #include <machine/cpufunc.h> as instructed by David Greenman to
avoid inb/outb linking errors.
NOTE: I just discovered that if GNUC is not used the inline functions will not be expanded from the include file and real inb/outb functions would
be needed.
when the drive had been left on a cylinder > 67 after kernel boot. The
most common case for this is booting a kernel that is located on
the inner cylinders of a floppy.
Also removed all occurences of spinwait(), replaced by DELAY.

First round of floppy changes. Try making `fd' more robust.
New features:
. ioctl command for setting the drive type (density etc.); restricted
to the super-user
. ioctl for getting/seting `drive options'; currently only option
is FDOPT_NORETRY: inhibit the usual retries; used when verifying
a newly formatted track
Fixes:
. function prototypes
. made all internal functions `static'
. cleaned up & corrected .h files
. restructured, to make the chaotic function sequence more rational
. compiled with -Wall, and cleared all warnings
. introduced a mirror for the (write-only) `digital output register',
to avoid the current kludge
. device probing completed by seeking/recalibrating, and looking
for track 0 being found
. holding the controller down in reset state while it is idle (and
thus saving allot of headaches)
. make requests fail that are not a multiple of the (physical)
sector size
. removed the fixed physical sector size (512 bytes), allowing for any
size the controller could handle (128/256/512/1024 bytes)
. replaced some silly messages
. fixed the TRACE* macro usage, debugging reports should be complete
now again (debugging output is HUGE! though)
. removed fd_timeout for SEEK command; seeks are always reported by
the controller to succeed, since the `success' only refers to the
controller's idea of success - there is no hardware line to tell about
the seek end (other than the `track 0' line)
. catch SENSEI's that report about a `terminated due to READY changed'
status - could happen after a controller reset
. converted ``hz / <something>'' divide operations to divisors that are
powers of two, so gcc can optimize them into shifts
. write/format operations are checked against a write-protected medium
now *prior* starting the operation
. error reports of `invalid command' and `wrong cylinder' will cause
shortcuts in the retrier() now
. fixed a bug in the retrier() causing bogus block numbers to be reported
. fdformat() does care for errors now
Known Bugs:
. no attempts have been made (yet) to improve the performance
. sometimes, bogus ``seek/recalib failed'' messages are logged; this
is still a bug in the driver, but it's not harmful since it's
usually caught by the retrier()

Fix from Bruce Evans. There were missing sets of parantheses:
1. The checks for the standard data selectors were botched, so %ss == 0
and probably %cs == 0 were allowed. A fix is enclosed. The checks
for the standard selectors could be omitted without losing anything
since the standard selectors pass the valid_ldt_sel() tests.

you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

This puppy is in good shape now.
It is a fully blown SCSI-driver, but it isn't a high performance one. It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes. It will run disks and tapes if asked to, but it isn't a
very good idea to do so. Transfer-rates max out at 600-700 kbyte/sec.
There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls. This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok. I have circumvented this by disabling the
pseudo-DMA in those cases.
It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.
You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.
I will fix any bugs I can get a handle on.

to something more recent than the ancient 1.2 release contained in
4.4. This code has the following advantages as compared to
previous versions (culled from the README file for the SunOS release):
- True multicast delivery
- Configurable rate-limiting of forwarded multicast traffic on each
physical interface or tunnel, using a token-bucket limiter.
- Simplistic classification of packets for prioritized dropping.
- Administrative scoping of multicast address ranges.
- Faster detection of hosts leaving groups.
- Support for multicast traceroute (code not yet available).
- Support for RSVP, the Resource Reservation Protocol.
What still needs to be done:
- The multicast forwarder needs testing.
- The multicast routing daemon needs to be ported.
- Network interface drivers need to have the `#ifdef MULTICAST' goop ripped
out of them.
- The IGMP code should probably be bogon-tested.
Some notes about the porting process:
In some cases, the Berkeley people decided to incorporate functionality from
later releases of the multicast code, but then had to do things differently.
As a result, if you look at Deering's patches, and then look at
our code, it is not always obvious whether the patch even applies. Let
the reader beware.
I ran ip_mroute.c through several passes of `unifdef' to get rid of
useless grot, and to permanently enable the RSVP support, which we will
include as standard.

mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.
