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.
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.
Religiously add back pmap_clear_modify() in vnode_pager_input until we figure
out why system performance isn't what we expect.
Submitted by: John Dyson (swap_pager) & David Greenman (vnode_pager)
in your kernel config now).
2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
are no other pseudo declarations.
2) DELAY(1) does nothing, it affects audio playing f.e:
driver can't play second half of disk, changed to DELAY(10)
3) Debugging messages #ifdef DEBUGed
Several examples of connection initiation follow. Although these
examples do not show connection synchronization using data-carrying
segments, this is perfectly legitimate, so long as the receiving TCP
doesn't deliver the data to the user until it is clear the data is
valid (i.e., the data must be buffered at the receiver until the
connection reaches the ESTABLISHED state).
