Added "device pci" and "device ncr" lines for a generic kernel with
support for the NCR 53c810 PCI SCSI host adapter (with no interrupts
configured, ie. working with 100Hz timer interrupts only).
Calculation of 'cd->cmdscount' now as in 'sd.c' (required for ncr scsi).
CDOUTSTANDING defined as '1' (as the comment says), was '2' in fact ...
Debugger takes an (char*) argument, changed macro definition accordingly.
Don't add to POBJS or SOBJS. bsd.lib.mk does it. Some objects were
duplicated.
Don't add to CLEANFILES. bsd.lib.mk does it. Some objects were
quadruplicated.
Define variables that are only used once close to where they are
used.
The ifdefs for avoiding building of profiled/shared objects when
NOPROFILE/NOPIC are set were not actually committed. The ifdefs
belong in bsd.lib.mk anyway.
with BOUNCE_BUFFERS. This is more intuitive, and is better for future
multiplatform support. Added BOUNCE_BUFFERS option to the GENERIC and
LINT kernel config files.
com.h/lpa.h. Removed all vestiges of com/lpa out of conf.c and also
fixed up the end of cdevsw/bdevsw to have "no" routines instead of
a NULL pointer (suggested by someone a few weeks back).
using min() to calculate the minimum of rss_cur,rss_max - since these
are now quad_t's and min() takes u_ints...the comparison later for exceeding
the rss limit was always true - resulting in rather serious page thrashing.
Now using new qmin() function for this purpose.
Fixed another bug where PG_BUSY pages would sometimes be paged out (bad!).
This was caused by the PG_BUSY flag not being included in a comparison.
will do most of the work for handling them. Only one extra flag and one
bogus dependency was used for machdep.c and there was never anything
special about the others.
Add locore.s, but commented out. It's still special.
Remove com.c and lpa.c.
SYSTEM_OBS. They are now normal objects.
Remove stale dependencies for the above now-normal objects and for
locore.o and generate dependencies using mkdep. Config doesn't
generate lists of assembler source files so the lists to be mkdep'ed
have to be given explictly. Only the standard *.s files are given,
so the dependencies for gnu/fpemul/*.s are incomplete. *.S files
would be handled right if config put them in CFILES.
Don't define NPX. It was replaced by NNPX > 0 years ago.
Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special
case.
Moving around the dependencies exposed a bug in make. It doesn't
know that assym.s and ./assym.s are the same. Add a rule tell it.
correct for C sources that are compiled by cc, while cpp (/usr/bin/cpp)
is bogus since it invokes /usr/libexec/cpp with different flags.
1.1.5 uses plain cc. This should be equivalent after -M is added, but
cc -M foo.s is completely broken (it invokes the assembler) while
cc -E -M foo.s just does nothing instead of generating a foo.o: foo.s
dependency.
IF $MKDEP_CPP is set, use it as the cpp instead of cc -E. Assembler
sources that are preprocessed using cpp directly should be mkdep'ed
with MKDEP_CPP=cpp. Such sources shouldn't exist but we still have
lots. foo.S should be compiled by cc -traditional (cc will invoke the
preprocessor) and foo.s should be compiled by cc (cc won't invoke the
preprocessor).
