abc260cb3f Fix FAT_CURSOR to give scanlines 0-15 instead of (the current start)-15. 1995-09-28 18:43:40 +00:00

0134f4737b o Support for CDIOCPREVENT and CDIOCALLOW ioctls that xcdplayer
were making and were no-brainers.  However, the xcdplayer
    eject button didn't work because xcdplayer gave up and didn't bother
    to try the EJECT ioctl anyway when CDIOCALLOW was not available.
    This all works now.

o   A change so that xcdplayer gets TOC entry data for the lead-out area
    on the disc.  Xcdplayer can now play the last track on a CD, which
    it would not do in earlier versions (but no one reported).
    Cdplayer gets the TOC data differently and it works in old and new
    versions.

o   Eliminated a race condition that caused the driver to sleep forever
    on very slow and heavily loaded systems on rare occasions when
    the system was doing lots of audio-related ioctls to the drive.

o   Fixed a problem where a locked drive could be unlocked by accessing
    one of the non-locking devs.  Door locking now follows the documented
    rules.

o   Made all wait channel strings unique to matcd.

2b76bec4e6 if_ze.c was derived from if_ed.c about 42 (!) versions ago. It is now
scheduled for demolition.  This is a first step: get rid of if_zereg.h,
by adding the five extra definitions to if_edreg.h.
Also add some definitions which will become needed when if_ze.c gets
replaced entirely by pccard and if_ed.c.  (this is a 2.1.0 candidate)

0e27a03ffb Perform more checking for proper loading of the UPAGES when a process
is swapped in.  Also, remove unnecessary map locking/unlocking during
selection of processes to be swapped out.

This code might afford proper panics as opposed to spontaneous reboots
on certain systems.  This should allow us to debug these problems better.

22ba64e870 Significantly simplify the fault clustering code. After some analysis by
David Greenman, it has been determined that the more sophisticated code
only made a very minor difference in fault performance.  Therefore, this
code eliminates some of the complication of the fault code, decreasing
the amount of CPU used to scan shadow chains.

164fd96f34 These changes fix a bug in the clustering code that I made worse when adding
support for EXT2FS.  Note that the Sig-11 problems appear to be caused by
this, but there is still probably an underlying VM problem that let this
clustering bug cause vnode objects to appear to be corrupted.

The direct manifestation of this bug would have been severely mis-read
files.  It is possible that processes would Sig-11 on very damaged
input files and might explain the mysterious differences in system
behaviour when phk's malloc is being used.

4dc45a5fa1 Remove duplicate definition for tcps_persistdrop, as added by davidg some
time ago.  I left in Garrett's one, because his was in the 4.4-Lite-2
location, making any diffs just that little bit smaller.

I presume this choice means that netstat needs to be recompiled before
"netstat -s" will give a meaningful answer on tcp stats.

3cb43dbdaf Generate prototypes for syscall-implementing functions. Put them in
<sys/sysproto.h> and use them (so far only) in kern/init_sysent.c.

Don't put $Id in generated files.

kern/syscalls.master:
I had to add some new fields to describe some non-orthogonal names.
E.g., the args struct for the syscall-implementing function foo()
is usually named `foo_args', but for getpid() it is named `args'.

sys/sysent.h:
sy_call_t is still incomplete to hide a couple of warnings.

0b4a1769be Our existing Cyrix cache-disable code was short-cutting the steps for
setting the control register.  Make the read and write operations two
completely separate steps.

While we're at it, pull in the whole set of Cyrix cache control options
from NetBSD-current,  since a few motherboards do the right thing with
the Cyrix chip.

There is no option to disable the internal cache completely (yet).
