3addba4f55 No longer use the cyclecounter to attempt to correct for late or missed
clock interrupts.

Keep a 1-in-16 smoothed average of the length of each tick.  If the
CPU speed is correctly diagnosed, this should give experienced users
enough information to figure out a more suitable value for `tick'.

c8f2fe8db8 First attempt at creating devfs entries for sliced devices. Doesn't
quite work yet, so the heart of it is disabled.

Added bdev and cdev args to dsopen().

drivers:
Fixed device names, links, minor numbers and modes.

wd.c:
Started actually supporting devfs.

diskslice.h:
Added devfs tokens to structs (currently 576 of them per disk! :-().

subr_diskslice.c:
Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times.  DEVFS is #undefed at the start so
that this shouldn't cause problems.

dd87702a51 Allocate DMA bounce buffers only when requested by drivers. Only the
fd and wt drivers need bounce buffers, so this normally saves 32K-1K
of kernel memory.

Keep track of which DMA channels are busy.  isa_dmadone() must now be
called when DMA has finished or been aborted.

Panic for unallocated and too-small (required) bounce buffers.

fd.c:
There will be new warnings about isa_dmadone() not being called after
DMA has been aborted.

sound/dmabuf.c:
isa_dmadone() needs more parameters than are available, so temporarily
use a new interface isa_dmadone_nobounce() to avoid having to worry
about panics for fake parameters.  Untested.

bfd6eab381 Fixed bugs introduced in rev. 1.127 (some broken 16650 support was
unintentionally committed):
- the fifo was completely disabled for low speeds.  Apart from being
  unnecessarily inefficient, this invalidated com->tx_fifo_size.
- `ftl' became a bogus name.
- the 16650 probe breaks the COM_NOFIFO() case and has other bugs
  (disabled, not fixed).

Fixed bogus change of the fifo settings for the non-speed of 0.  This
bug made the above fifo bug occur even at non-low speeds.

Fixed the modes of the cua devices.  It isn't possible to set the uid
and gid correctly since the kernel can't know who uucp.dialer is.

Register the devswitch at device attach time.  SYSINIT() is not
the right way to initialize devswitches (if anything :->).
Eventually, the devswitch should be deregistered at device detach
and/or unload time and reregistered at device attach time ...  Then
some com->gone tests could be removed.

Cleaned up some other recent changes.

d1022821ae Removed my devsw access functions [un]register_cdev() and
getmajorbyname() which were a better (sigh) temporary interface to
the going-away devswitches.

Note that SYSINIT()s to initialize the devswitches would be fatal
in syscons.c and pcvt_drv.c (and are bogus elsewhere) because they
get called independently of whether the device is attached; thus
devices that share a major clobber each other's devswitch entries
until the last one wins.

81ab2caf0a Replaced nxreset by noreset (if the reset function gets called, then the

if somehow gets called).

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)

9350db19e7 Fix Pentium CPU rate diagnosis:
- Don't print out meaningless iCOMP numbers, those are for droids.
	- Use a shorter wait to determine clock rate to avoid deficiencies
	  in DELAY().
	- Use a fixed-point representation with 8 bits of fraction to store
	  the rate and rationalize the variable name.  It would be
	  possible to use even more fraction if it turns out to be
	  worthwhile (I rather doubt it).

56cb20cd72 Removed builtin list of port addresses. The address for sio3
conflicted with S3 graphics cards.  Now users should put sio[2-3]
in the config file if the hardware exisst, even if the probe is
certain to fail due to an interrupt conflict.  Otherwise, ports
sharing the interrupt may fail the probe if the system is warm
booted while sio[2-3] are active (perhaps under another OS).  The
same problem for nonstandard ports is now handled better than
before.

53ac6efbd8 OK, that's it..
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..

Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.

some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

If you want to add a new device in conf.c
please  make sure I know
so I can keep it up to date too..

as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)

7146c13e43 the second set of changes in a move towards getting devices to be
totally dynamic.

this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.

If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..

when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.

By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.

For this edit,
each of the files has the following code inserted into it:

obviously, tailored to suit..
----------------------somewhere at the top:
#ifdef JREMOD
#include <sys/conf.h>
#define CDEV_MAJOR 13
#define BDEV_MAJOR 4
static void 	sd_devsw_install();
#endif /*JREMOD */
---------------------somewhere that's run during bootup: EVENTUALLY a SYSINIT
#ifdef JREMOD
        sd_devsw_install();
#endif /*JREMOD*/
-----------------------at the bottom:
#ifdef JREMOD
struct bdevsw sd_bdevsw =
	{ sdopen,	sdclose,	sdstrategy,	sdioctl,	/*4*/
	  sddump,	sdsize,		0 };

struct cdevsw sd_cdevsw =
	{ sdopen,	sdclose,	rawread,	rawwrite,	/*13*/
	  sdioctl,	nostop,		nullreset,	nodevtotty,/* sd */
	  seltrue,	nommap,		sdstrategy };

static sd_devsw_installed = 0;

static void 	sd_devsw_install()
{
	dev_t descript;
	if( ! sd_devsw_installed ) {
		descript = makedev(CDEV_MAJOR,0);
		cdevsw_add(&descript,&sd_cdevsw,NULL);
#if defined(BDEV_MAJOR)
		descript = makedev(BDEV_MAJOR,0);
		bdevsw_add(&descript,&sd_bdevsw,NULL);
#endif /*BDEV_MAJOR*/

	}

floppies must have been random in 2.x since we reintroduced sorting
on b_pblkno on 1995/03/18.  Drivers still initialize b_cylin/b_resid
although this is no longer used.

Removed unused, wrong function fdsize().  (Returning 0 means that the
device exists and has size 0, not that the device doesn't exist.
swaponvp() allows for size 0 by stupidly calling the d_psize function
twice if the size isn't 0.  setdumpdev() doesn't allow for it.)

4ff3de8e80 Added `#include "ioconf.h"' to <machine/conf.h> and cleaned up the
misplaced extern declarations (mostly prototypes of interrupt handlers)
that this exposed.  The prototypes should be moved back to the driver
sources when the functions are staticalized.

Added idempotency guards to <machine/conf.h>.  "ioconf.h" can't be

f668386c04 sio.c:
Fix the tests for being a console by reverting to the ones that
were used before the the RB_SERIAL changes.  RB_SERIAL only needs
to be tested in one place.  The initialization of comconsole was
wrong before the RB_SERIAL changes for the COMCONSOLE case.  This
may have been the cause of the unnecessary changes.

Start eliminating #includes of <i386/i386/cons.h>.  This header is
supposed to be included from <machine> although it should be
completely machine-independent and included from <sys>.

Remove a wrong XXX comment.  `comconsole' is used to test for being
a console and even the tests for deciding the default termios state
are necessary (the semi-reentrant i/o routines don't handle ordinary
device i/o).

9fa18570a2 Obtained from: partly from ancient patches of mine via 1.1.5
Introduce TS_CONNECTED and TS_ZOMBIE states.  TS_CONNECTED is set
while a connection is established.  It is set while (TS_CARR_ON or
CLOCAL is set) and TS_ZOMBIE is clear.  TS_ZOMBIE is set for on to
off transitions of TS_CARR_ON that occur when CLOCAL is clear and
is cleared for off to on transitions of CLOCAL.  I/o can only occur
while TS_CONNECTED is set.  TS_ZOMBIE prevents further i/o.

Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp)
and TSA_HUP_OR_INPUT(tp).  The former address is now used only for
off to on carrier transitions and equivalent CLOCAL transitions.
The latter is used for all input events, all carrier transitions
and certain CLOCAL transitions.  There are some harmless extra
wakeups for rare connection- related events.  Previously there were
too many extra wakeups for non-rare input events.

Drivers now call l_modem() instead of setting TS_CARR_ON directly
to handle even the initial off to on transition of carrier.  They
should always have done this.  l_modem() now handles TS_CONNECTED
and TS_ZOMBIE as well as TS_CARR_ON.

gnu/isdn/iitty.c:
Set TS_CONNECTED for first open ourself to go with bogusly setting
CLOCAL.

i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c:
We fake carrier, so don't also fake CLOCAL.

kern/tty.c:
Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to
test CLOCAL.  TS_ISOPEN was tested instead, but that broke when we disabled
the clearing of TS_ISOPEN for certain transitions of CLOCAL.

Testing TS_CONNECTED fixes ttyselect() returning false success for output
to devices in state !TS_CARR_ON && !CLOCAL.

Optimize the other selwakeup() call (this is not related to the other
changes).

f3b37f91c1 Improve input flow control.
Use input buffer watermarks of TTYHOG-512 (high) and (high)*7/8
(low) instead of TTYHOG/2 (high) and TTYHOG/5 (low) to agree with
some drivers.  512 is magic and some things depended on TTYHOG/2
>= TTYHOG-512 to work; now they depend on the 512 magic not changing
and TTYHOG-512 being significantly larger than 0.  This should be
handled in ttsetwater().

Separate the decision about whether to do input flow control from
doing it.  ttyblock() now just starts input flow control (hardware
and/or software) and there is a new function ttyunblock() to stop
it.  The decisions are the same except for the watermark changes
and allowing for input expansion for PARMRK.

When flushing input, try harder at first to send a start character
if required, but give up if the first attempt fails.

cy.c, rc.c, sio.c:
Simplify: let ttyinput() handle input flow control if it is not
being bypassed.  Use ttyblock() to start flow control otherwise.

rc.c:
Use same input flow control test as elsewhere: test in a more
efficient order and start flow control at >= highwater instead of
at > highwater.

It's probably not worth making ttwwakeup() a macro or an inline
function.  The cost of the function call is relatively small when
there is a process to wake up.  There is usually a process to wake
up for large writes and the system call overhead dwarfs the function
call overhead for small writes.

33dc7e1b84 Reduce timeout frequency from `hz' to 0 if no ports are open or to 1 if
no ports are active, provided there are no polled ports and no
`LOSESOUTINTS' ports.  Do a little more in the interrupt handler instead.
This is a little less efficient if there are are many active ports but
a little more efficient otherwise.  Polled ports are ones with no irq
specified (as before).  `LOSESOUTINTS' ports are ones with 0x08 set in
their config flags.  Unless this flag is set, it will now take up to one
second to recover from lost output interrupts, if any.  Some 8250s and
16450s lose output interrupts.

Improve output buffering: copy the clist buffer to 2 linear buffers if
necessary and possible instead of to 1.  Handle an arbitrary queue of
buffers in the interrupt handler.  Check for waking up sleepers after
copying characters out of the clist buffer instead of before.

routines are more machine independent.

2cad35d11b Several fixes to help "raw" tty mode work correctly with
BREAK/parity/framing errors.
Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
1) Discard BREAK/parity at interrupt level when apropriate IGN*
is set in iflag. It helps "raw" mode works even IGN* is set.
2) Zero parity (if INPCK) and framing directly in buffer
before passing it to b_to_q() in "raw" mode.
Efficency:
interrupt level: if no error occurse, only two "test" commands added
"raw" mode: buf scan incc times for parity/framing added

  all driver features must be _optional_. Modern VGAs have internal
  configuration utilities to set cursor shape/blinking which stored
  into cards ROM, and syscons nuke out such features completely
  by forcing software cursor. Moreover, software cursor is hard
  to distinguish on standouted (or near standouted) fields and
  tends to disappearse from the screen.
  Set "flags 0x4" to enable software cursor now.

o Cleanup screen savers.

o Don't draw cursor if saver or blinker is active.

o Duplicated code moved to functons.

o Add more checks for blinker in progress, character lost otherwise
  when blinker restore old contents.

o Reduce blinking counter to 3, too slow in old variant.

Use bcopyw() instead of move_up() and move_down().  bcopyw() handles
overlapped copies and should be faster.  Actually use bcopy().  bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit.  bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.

63c5d14d1b Miscellaneous changes from Bill Paul:
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
  ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
  has only 8K of shared memory. The only way to have it properly detected
  is to zero and test a few bytes of memory just about the first 8K region.
  If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.

  I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).

- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
  the last column, like it should. You don't really notice this unless you
  use certain programs that write all the way out to, say, the 80th column,
  like VMSmail. Along with a one-line fix for this are some changes to
  implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your

Bruce Evans
a3b33372b9 Maintain a new variable `timer0_overflow_threshold' so that microtime()
doesn't have to calculate it every call.

Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it
correctly.  Previously we lost a few 8253 cycles for every "prescaled"
clock interrupt, and the lossage grows rapidly at 16 KHz.  Now we
only lose a few cycles for every standard clock interrupt.

Rename `*_divisor' to `*_max_count'.

Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.

Don't allow preposterously large interrupt rates.  Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.

Clean up declarations.

Include <machine/clock.h> to check our own declarations.

25dd4b72b8 Only log errors every second (instead of every 5-10 msec) and check for
errors at a lower ipl.  clist starvation problems can cause hundreds of
tty buffer overflows per second and logging them all amplified the
problems.  This problem was less serious in 1.1.5.

Avoid a race in the check for starting a new block of output.  com_events
was sometimes messed up and siopoll() looped endlessly.  This bug was
introduced in 2.0.

Clean up previous 2 commits.  Rename sio_registerdev() to sioregisterdev()
to match the (bad) surrounding naming conventions.  There should be a
generic_registerdev().

5d04c702eb Several minor fixes to the floppy driver:
.	avoid resetting the FDC every time the last motor is going off;
	instead, give it a 60-second period for possible later reactivation.
	This prevents us from needing to recalibrate the FDC too often,
	but still allows for an ``automagic error recovery', just in case the
	controller is absolutely stuck. (Simply wait for 60 seconds, and
	try it again.)

.	made the floppy head settle time after a seek a constant
	that might be overridden by a config option. (Well, actually the
	divisor of the settle time). Pepople often reported problems with
	their floppies, so i need a simply mechanism that allows them
	to play with that value. (I personally cannot find any problem
	on *my* drives.)

.	implement the FD_DEBUG ioctl command, in case the driver
	is compiled with DEBUG turned on.

.	removed a bogus parameter from a printf; the remaining warnings
	from gcc -Wall seem to be warnings about the %b format gcc cannot
	understand

.	rearrange Garett's code to fit better in the existing structure
	of #define/type/function ordering.

.	make everything fit into 79 columns again.

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).

if_ed.c, syscons.c:  Set the above flag.  ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)

bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.

Fix endless loop in siopoll() for an event on a tty with no tty struct.
Don't generate unwanted interrupts in the serial console driver.  These
bugs probably don't matter unless the tty struct is dynamically allocated.

Support polled mode.  To use it, leave out the irq and the vector in
the config file.  It only causes extra overhead for open polled ports.
The maximum usable speed is approximately 1000 bps for a 16450 and
15000 bps for a 16550.
