19393bbed2 Support 32bit access to IDE disks, if it seems to work for the drive.
You will normally have to have a VLB or other 32bit IDE "controller" for
this to work.

Depending on your setup, this may gain you 20-100 % speed from your disk.

b5d89ca8ad Load the kernel symbol table in the boot loader and not at compile time.
(Boot with the -D flag if you want symbols.)

Make it easier to extend `struct bootinfo' without losing either forwards
or backwards compatibility.

ddb_aout.c:
Get the symbol table from wherever the loader put it.
Nuke db_symtab[SYMTAB_SPACE].

boot.c:
Enable loading of symbols.  Align them on a page boundary.  Add printfs
about the symbol table sizes.
Pass the memory sizes to the kernel.
Fix initialization of `unit' (it got moved out of the loop).
Fix adding the bss size (it got moved inside an ifdef).
Initialize serial port when RB_SERIAL is toggled on.
Fix comments.
Clean up formatting of recently added code.

io.c:
Clean up formatting of recently added code.

netboot/main.c, machdep.c, wd.c:
Change names of bootinfo fields.

LINT:
Nuke SYMTAB_SPACE.
Fix comment about DODUMP.

Makefile.i386:
Nuke use of dbsym.
Exclude gcc symbols from kernel unless compiling with -g.
Remove unused macro.
Fix comments and formatting.

genassym.c:
Generate defines for some new bootinfo fields.  Change names of old ones.

locore.s:
Copy only the valid part of the `struct bootinfo' passed by the loader.
Reserve space for symbol table, if any.

machdep.c:
Check the memory sizes passed by the loader, if any.  Don't use them yet.

bootinfo.h:
Add a size field so that we can resolve some mismatches between the loader
bootinfo and the kernel boot info.  The version number is not so good for
this because of historical botches and because it's harder to maintain.
Add memory size and symbol table fields.  Change the names of everything.

Hacks to save a few bytes:

asm.S, boot.c, boot2.S:
Replace `ouraddr' by `(BOOTSEG << 4)'.

boot.c:
Don't statically initialize `loadflags' to 0.  Disable the "REDUNDANT"
code that skips the BIOS variables.  Eliminate `total'.  Combine some
more printfs.

boot.h, disk.c, io.c, table.c:
Move all statically initialzed data to table.c.

io.c:
Don't put the A20 gate bits in a variable.

11fa0751bc Fix the "wd" count stat. The seek and xfer stats are still very bogus
for wd (they both count the number of sectors).  The wpms stat is still
moderately bogus for all drivers.  Even the count stat could be handled
better (partial blocks should be counted as full blocks; should errors
and retries be counted?).

e0985944c1 Improve the case for ST506 disks a bit: Pick up Bios-geometry.
That was the good news.  The bad news is that bad144 is a proper mess,
and I don't have time to fix it now, so you will probably not be able to
use it anyway.
Sorry guys, go out and buy a 100Mb IDE drive and a paddleboard :-(
If somebody wants to pick up on this:  bad144 needs to learn how to
stay inside our slice of the disk.  That's the trick.

2f86936a07 Finished device configuration database work for all ISA devices (except `ze')
and all SCSI devices (except that it's not done quite the way I want).  New
information added includes:

-	A text description of the device
-	A ``state''---unknown, unconfigured, idle, or busy
-	A generic parent device (with support in the m.i. code)
-	An interrupt mask type field (which will hopefully go away) so that
.	  ``doconfig'' can be written

This requires a new version of the `lsdev' program as well (next commit).

WARNING: might hide some bug below!  I commit this to improve the stability

 I have been running a kernel with this change since October 4th; barring
unrelated network router troubles, the pitiful little machine has
completed several builds without any interaction from me, and continues
to chug along.

 I re-read wd.c, and added appropriate printfs() to look for references
to dk_badsect[].  My changes should have printed something when dk_badsect[]
was referenced.

 I got no output :-(

 Thus, I'm forced to concluded that something else is examining some
spurious memory... which happened to be in dk_badsect[] of the disk structure
in wd.c.  I can find no other explanation of why this unnecessary
initialization causes things to operate correctly.

 On the premise that such an initialization isn't going to hurt anything,
I'm going to suggest it go into 2.0.

 I'd like to thank everyone for there assistance, particularly David,
John and Bruce.

f540b1065a Change all #includes to follow the current Berkeley style. Some of these
``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 @

0e195446b7 Bug fixes and performance improvements from John Dyson and myself:
1) check va before clearing the page clean flag. Not doing so was
	causing the vnode pager error 5 messages when paging from
	NFS. (pmap.c)
2) put back interrupt protection in idle_loop. Bruce didn't think
	it was necessary, John insists that it is (and I agree). (swtch.s)
3) various improvements to the clustering code (vm_machdep.c). It's
	now enabled/used by default.
4) bad disk blocks are now handled properly when doing clustered IOs.
	(wd.c, vm_machdep.c)
5) bogus bad block handling fixed in wd.c.
6) algorithm improvements to the pageout/pagescan daemons. It's amazing
	how well 4MB machines work now.

068a409099 Beginning of change set for making more friendly laptop configurations.
Changes _only_ take effect if `options LAPTOP' is set.

Note:  This one is distinctly dodgy. When my IDE drive spins back up from sleep
mode, it generates this `extra interrupt' condition by spinning back up and
generating an intr, though without any particular action required.  This
message coming out every time is rather annoying, and thus disabled.
However, what I'm not at all sure of is whether or not all IDE drives will
behave in the same way, or if perhaps it needs to be done in a more complicated
fashion by detecting this more involved "I've spun up and am just saying hi"
condition.  This is a simple change and easy to back out/ammend if anybody has
any better ideas.

768e8947c6 From: bde@kralizec.zeta.org.au (Bruce Evans)
o merged and fixed timeout code from sos.
	o merged DOS partition support from sos.
	o fixed "extra" interrupts.
	o check if malloc retuns NULL :-(.
	o print drive size as in NetBSD
	o after an error, return the residual count, not 0.
	o give up early for > 16 heads.
	o cleaned up the old-drive detection in wdgetctlr().
	o rewrote wddump().  I'd been putting this off because
	  I'd had the dump disabled since 0.0 and had no idea
	  if even the standard version worked.  It didn't:
	  (0) syscons' sgetc() interface broke some keyboard
	  stuff.
	  (1) CADDR1 is mapped using pmap() and pmap got a NULL
	  pointer trap (at least when I got to wddump() using
	  call diediedie from ddb) because the pte for CADDR1
	  is only supposed to be hacked on directly (e.g. in
	  physcopyseg()).
	  (2) bad144 handling was not done.
	  (3) it was slooow (3600 sectors/minute) because my
	  controller doesn't cache writes.
	o miscellaneous other cleanups, e.g., removed scattered
	  patchkit/terry dates.
	o lots of reformatting.

To be done:
	o Merge/fix TIH/NetBSD bad144 code (doesn't belong in any
	  particular driver.  Why aren't we using i386/dkbad.c?).
	o Merge/fix Dyson/NetBSD clustering code (large parts
	  should be shared).
	o Fix/extend the partition in use bits.  Support extended
	  partitions.  This should be shared by all disk drivers.  Swap
	  to a DOS partition so that the swap space can be shared with
	  linux.
	o Don't use polling except for initialization.  Need to
	  reorganise the state machine.  Then "extra" interrupts
	  shouldn't happen (except maybe one for initialization).
	o Fix disklabel, boot and driver inconsistencies with
	  bad144 in standard versions.
	o Look at latest linux clustering methods.  Our disksort()
	  gets in the way of clustering.
	o cleaned up the ATA changes (needs more work.  I think
	  the ATA specs say that the only thing really wrong with
	  the original version of wx is that there was no test
	  for drive-ready before some commands.  400 nsec delay
	  suffices for almost everything and 400 nsec delay is
	  usually "free").

4aba964ef1 New wd driver, based on Bruce Evans 'wx/altwd' driver which has passed
enough tests to be considered more stable than current driver.

Lots of work by Bruce, David G., and Guido have gone into this version, and
more is to come in the future.

Support for multiple controllers is in, but doesn't work correctly with
different controllers (IDE AND MFM), but multiple alike controllers appears
to work.

Most of the stray interrupts problems should be fixed, although you will
get a couple 'extra interrupts' when disklabeling and on startup.

and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten.  This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax.  These were all
fixed, and the result of fixing some of them means that -Wall is now a
