UserConfig. (Also document other syscons flags which were previously
undocumented).
Requested by: bde
negative-logic flags (flags 0x01 and 0x02 for npx0, defaulting to unset = on).
This changes the default from off to on. The options have been in current
for several months with no problems reported.
Added a boot-time negative-logic flag for the old I5886_FAST_BCOPY option
which went away too soon (flag 0x04 for npx0, defaulting to unset = on).
Added a boot-time way to set the memory size (iosiz in config, iosize in
userconfig for npx0).
LINT:
Removed old options. Documented npx0's flags and iosiz.
options.i386:
Removed old options.
identcpu.c:
Don't set the function pointers here. Setting them has to be delayed
until after userconfig has had a chance to disable them and until after
a good npx0 has been detected.
machdep.c:
Use npx0's iosize instead of MAXMEM if it is nonzero.
support.s:
Added vectors and glue code for copyin() and copyout().
Fixed ifdefs for i586_bzero().
Added ifdefs for i586_bcopy().
npx.c:
Set the function pointers here.
Clear hw_float when an npx exists but is too broken to use.
Restored style from a year or three ago in npxattach().
2.2 are more obvious. -Winline is unimportant, but -W gives thousands
of warnings for comparisions. Turning off -W also loses warnings for:
- auto variables clobbered by longjmp. Not much of a problem in the kernel.
- functions returning without a value. I don't like losing this.
- an expression statement or the left side of a comma operand contains no
side effects. Turning this off also stops warnings for the low quality
debugging macros in gsc.c and lpt.c.
Should be in 2.2.
if I586_CPU is defined. Note there is a runtime check so the code
won't be run for non-Pentium CPUs anyway.
2.2 candidate, this code has been tested for almost half year in -current.
will be renamed.
Fixed comments about unsupported network protocols.
ncr0 is a controller, not a device. This make no difference.
Added undocumented options DEVFS_ROOT, I586_CTR_GUPROF and I586_PMC_GUPROF.
Sorted undocumented options.
3COM 3C590 Etherlink III PCI,
3COM 3C595 Fast Etherlink PCI,
3COM 3C592 Etherlink III EISA,
3COM 3C590 Fast Etherlink EISA,
3COM 3C900 Etherlink XL PCI and
3COM 3C905 Fast Etherlink XL PCI.
This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.
Especially the 3c59X support should be pretty stable now.

AHC_FORCE_PIO - This forces the driver to use PIO even on systems that
say they have memory mapped the controller's registers. This
seems to fix Ken Lam's problems. I've also placed this option
in the GENERIC kernel file so that we are guaranteed to install
even on these flakey machines.
AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
the 398X controllers allowing a totoll of 255 non-paged SCBs.
This doesn't work quite yet, so this option is mostly here to
help 398X owners to experiment and give me feedback until this
works properly.

- use a more accurate and more efficient method of compensating for
overheads. The old method counted too much time against leaf
functions.
- normally use the Pentium timestamp counter if available.
On Pentiums, the times are now accurate to within a couple of cpu
clock cycles per function call in the (unlikely) event that there
are no cache misses in or caused by the profiling code.
- optionally use an arbitrary Pentium event counter if available.
- optionally regress to using the i8254 counter.
- scaled the i8254 counter by a factor of 128. Now the i8254 counters
overflow slightly faster than the TSC counters for a 150MHz Pentium :-)
(after about 16 seconds). This is to avoid fractional overheads.
files.i386:
permon.c temporarily has to be classified as a profiling-routine
because a couple of functions in it may be called from profiling code.
options.i386:
- I586_CTR_GUPROF is currently unused (oops).
- I586_PMC_GUPROF should be something like 0x70000 to enable (but not
use unless prof_machdep.c is changed) support for Pentium event
counters. 7 is a control mode and the counter number 0 is somewhere
in the 0000 bits (see perfmon.h for the encoding).
profile.h:
- added declarations.
- cleaned up separation of user mode declarations.
prof_machdep.c:
Mostly clock-select changes. The default clock can be changed by
editing kmem. There should be a sysctl for this.
subr_prof.c:
- added copyright.
- calibrate overheads for the new method.
- documented new method.
- fixed races and and machine dependencies in start/stop code.
mcount.c:
Use the new overhead compensation method.
gmon.h:
- changed GPROF4 counter type from unsigned to int. Oops, this should
be machine-dependent and/or int32_t.
- reorganized overhead counters.

Also disabled -Wunused. It caused too many warnings even for me.
The sign mismatch warnings should be fixed first. They are more
important and harder to disable (they are controlled by -W, which
controls too many things).
First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now. Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later. This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted. Now we generate the symbol file in
release.8.
Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two
effects:
1. Userconfig is always entered, rather than only after a -c
(don't scream yet, it's not as bad as it sounds).
2. Userconfig reads a message string which can optionally be
written just past the boot blocks. This string "preloads"
the userconfig input buffer and is parsed as user input.
If the first command is not "USERCONFIG", userconfig will
treat this as an implied "quit" (which is why you don't need
to scream - you never even know you went through userconfig
and back out again if you don't specifically ask for it),
otherwise it will read and execute the following commands
until a "quit" is seen or the end is reached, in which case
the normal userconfig command prompt will then be presented.
How to create your own startup sequences, using any boot.flp image
from the next snap forward (not yet, but soon):
% dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO
USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO
Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched. The default
boot.flp startup sequence is now, in fact, this:
USERCONFIG
intro
visual
(Since visual never returns, we don't need a following "quit").

for headers in the compile directory work unsurprisingly. Without
-I-, the search for "foo.h" begins in the directory of the file
that includes it, and the compile directory is only searched because
`-I.' is in ${INCLUDES}.
Removed -I$S/sys from ${INCLUDES}. It was once necessary to find
things like "param.h" in $S/sys. Now <sys/param.h> is found in $S.
I maintain that it saves more power to simply "hlt" the CPU than to
spend tons of time trying to tell the APM bios to do the same.
In particular if you do it 100 times a second...
bsd.obj.mk. Also, a make target called objwarn checks to see
if ${.OBJDIR} != ${.CURDIR} and ${.OBJDIR} != ${CANONICALOBJDIR}
and outputs a warning. (No warning for the latter if MAKEOBJDIR or MAKEOBJDIRP
REFIX is set). objwarn is called from all targets in bsd.prog.mk, bsd.kmod.mk,
and bsd.lib.mk.

biosextmem > 65536, but biosextmem is a 16-bit quantity so it is
guaranteed to be < 65536. Related cruft for biosbasemem was
mostly cleaned up in rev.1.26.
It worked because it is spelled correctly in LINT.
Added old obscure syscons options MAXCONS, SLOW_VGA and XT_KEYBOARD.
This file should be sorted both alphabetically and on the module
name by using a consistent prefix for each module, but there is no
consistency in the old options. E.g., MAXCONS is spelled PCVT_NSCREENS
for pcvt.
