Put the printf("can't map 3c507 ram.. into an ifdef DEBUG. This will
confuse only normal users and the ie0 found/not found is sufficient.
Submitted by:
1) if_ie.c:
Changed a printf and put a space in it. Formerly the "<3C507>"
confused the syslog. He tried to see that as the priority to
log that message.
2) isa_device.h:
Changed the iobase variable from short to u_short. EISA
Adresses can go up to 0xf000 and the sign extension doesn't
look good in the probe output. Example:
ep1 at 0xffff8000-0xffff8000f is not good :-), i like more a
ep1 at 0x8000-0x8000f.
3) isa.c:
Changed a string constant from "probe" to "prob", it gets
later already an "ed" tagged on the end.
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
find something useful to do other than taking credit for other people's
work. Also make the 3C507 bits match the indentation style of the rest of
the code.
Merged changes from 2.0 version (revisions 1.46-1.50) by hand.
Finished conversion to clists: removed flush of tty output buffer
in comflush() (most writes were truncated to 256 bytes) and restored
bypass of ttyinput() in siopoll().
Finished conversion to 2.0 types - more void *'s, less caddr_t's,
less casts, no Dev_t's.
Only these things are seriously broken now compared with 1.1.5:
waiting for output complete is impossible so ttywait() can deadlock;
sioclose() isn't called enough so sioopen() sometimes returns EBUSY
unnecessarily; input flow control is not implemented.

Add the 3com 3C507 card to the if_ie.c driver. The files elink.c and
elink.h are helding routines that are shared between the 3C507 and the
3C509/3C579. if_ie507.h are constant declarations unique to the 3C507.
The code is based on the NetBSD driver if_ie.c donated to NetBSD by
Rafal Boni and then modified by Charles Hannum.
Added a missing #ifdef INET wrapper in lpt.c
Main change:
Removed the timeout_func_t casts from timeout calls and
correctly defined the timeout routines to conform to
the new format.
lpt.c doesn't have this change.

revision. They caused redundant redeclaration warnings because I
forgot to declare them as extern and gcc-2.6.0 treats "extern int x[];"
slightly different from "int x[];" (this is probably a bug). The new
versions will cause RR warnings from gcc-2.4.5 because it does not
understand that the second declaration in "extern int x[]; int x[1];"
is not redundant. The variables don't actually need to be declared
in a header file because they are used in only one C source file and
one assembler source file, but I want all public variables and
comments about them to be findable by grepping *.h.
use of timeout_t -> timeout_func_t in aha1542 and aha1742 drivers.
2) fix a bug in the portalfs that was uncovered by better prototyping -
specifically, the time must be converted from timeval to timespec
before storing in va_atime.
3) fixed/added some miscellaneous prototypes
into one, hopefully functioning, Ultrastore driver. Any Ultrastore owners
out there - please speak up! We need to test this puppy.

This is the slowest and most stupid of our SCSI-drivers, but it is there
and it works. It has been tested with CD-ROM and disk.
It uses no interrupts, no DMA, just polled I/0.
Transfer-rate is <= 100Kbyte/sec.
If you set the jumpers on the board, you can change the unit-number and
you will be able to have four of these co-exist in one computer, why one
would do that is somewhat unclear though.
If I ever get my hand on the docs for this, I will improve it of course,
but for now we can install and access those CD-ROMs.
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.
NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
/usr/src/sys/i386/isa/clock.c:
o Garrett's statclock changes.
o Wire xxxintr, not Vclk.
o Wire using register_intr(), not setidt().
/usr/src/sys/i386/isa/icu.s:
o Garrett's statclock changes.
o Removed unused variable high_imask.
o Fake int 8 for rtc as well as int 0 for clk. Required for kernel
profiling with statclock, harmless otherwise.
/usr/src/sys/i386/isa/isa.c:
o Allow isdp->id_irq and other things in *isdp to be changed by
probes. Changing interrupts later requires direct calls to
register_intr() and unregister_intr() and more care.
ALLOW_CONFLICT_* is brought over from 1.1.5, except
ALLOW_CONFLICT_IRQ is not supported. IRQ conflict checking is
delayed until after probing so that drivers can change the IRQ
to a free one; real conflicts require more cooperation between
drivers to handle.
o Too many details to list.
o This file requires splitting and a lot more work.
/usr/src/sys/i386/isa/isa_device.h:
o Declare more things more completely.
/usr/src/sys/i386/isa/sio.c:
o Prepare to register interrupt handlers as fast.
/usr/src/sys/i386/isa/vector.s:
o Generate entry code for 16 fast interrupt handlers and 16 normal
interrupt handlers. Changed some constants to variables:
# $unit is now intr_unit[intr]. Type is int. Someday it should
be a cookie suitable for the handler (e.g., a struct com_s for
sio).
# $handler is now intr_handler[intr].
# intrcnt_actv[id_num] is now *intr_countp[intr]. The indirection
is required to get a contiguous range of counters for vmstat
and so that the drivers depend more in the driver than on the
interrupt number (drivers could take turns using an interrupt
and the counts would remain correct). There is a separate
counter for each device and for each stray interrupt. In
1.1.5, stray interrupt 7 clobbers the count for device 7 or
something worse if there is no device 7 :-(.
# mask is now intr_mask[intr] (was already indirect).
o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
not _VdevU (U = unit).
o Removed BUILD_VECTORS stuff. There's a trace of it left for
the string table for vmstat but config now generates the
string in one piece because nothing more is required.
o Removed old handling of stray interrupts and older comments
about it.

not provide the full accuracy of a randomized statistical clock, it does
provide greater accuracy than the previous method, while not significantly
increasing overhead. It also provides profiling support at 1024 Hz.
You must re-compile config before making a new kernel, or you will end
up with unresolved symbols.
Reviewed uy: Bruce evans said it worked for him.
Added code to check for an adaptec 1542B Version 3.20 Board. This was the
first board that supports >1Gb drives and has the extended bios. So we
need also to disable the exbios like it is done for the 1542C/CF boards.
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.
This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:
rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make
Added my if_lp TCP/IP driver to lpt.c.
I have (surprise) not been able to test it on a 2.0 machine yet. Connect the
machines with a parallel "lap-link" cable, and get rates from 35 kbyte/sec
up to 75 kbyte/sec. (when ftp'ing foo: dev/zero -> bar:/dev/null).
The same lpt.c file should compile under 1.1.5.1 without problems.
I think we should promote this feature when we dump 2.0 on the expectant
public, because it provides a cheap and efficient way to move data to and
from notebooks &c. It is not a replacement for ethernet, but a cheap
substitute sometimes.
This driver supports all the DEC EtherWORKS III NICs (DE203, DE204,
and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202,
DE422). DEPCA-style boards prior to the DE200 have not been tested
and may not work.
