Fix the acpi attachment to always start the worker thread.
The previous change to split the worker thread start out of fdc_attach()
did not start the worker thread if the fdc device in the ACPI namespace
did not have an _FDE method. This fixes hangs when booting with a
floppy controller enabled on certain machines with ACPI.

Adjust the fdc worker thread startup to work when APs are started earlier.
- Enable the commented out locking in fd_probe(). The worker thread
should not be running yet (even after these changes), but better to be
safe than sorry.
- Defer starting the worker thread until after the child drives have been
probed. The worker thread startup is moved into a fdc_start_worker()
thread that the various front ends call at the end of attach. As a
side effect this fixes a few edge cases that weren't shutting down the
worker thread if attach encountered a late failure.
- When executing the initial reset requested by attach in the worker
thread, use DELAY() instead of a tsleep() if cold is set.

Don't wakeup the fdc worker thread once a second when idle.
The fdc worker thread was using a one second timeout while waiting for
a new bio to arrive or for the device to detach. However, the driver
already does a wakeup when queueing a new bio or asking the thread to
detach, so the timeout only served to waste CPU time waking up the
thread once a second just so it could go right back to sleep. Use an
infinite timeout instead.

Do not use "Enable Implied Seek" on enhanced floppy controllers. This
breaks the "2step" feature of the driver, e.g. in order to read 360
KiB media on a 1200 KiB drive.
As the only potential advantage of implied (vs. explicit) seeks is to
minimize the software effort, yet our driver always contained the
logic needed for explicit seeks, simply dropping implied seeks is the
best solution without introducing risks for new bugs. There is no
performance penalty, reading a 1440 KiB medium takes exactly the same
time with both, implied or explicit seeks.

Make isa_dma functions MPSAFE by introducing its own private lock. These
functions are selfcontained (ie. they touch only isa_dma.c static variables
and hardware) so a private lock is sufficient to prevent races. This changes
only i386/amd64 while there are also isa_dma functions for ia64/sparc64.
Sparc64 are ones empty stubs and ia64 ones are unused as ia64 does not
have isa (says marcel).
This patch removes explicit locking of Giant from a few drivers (there
are some that requires this but lack ones - this patch fixes this) and
also removes the need for implicit locking of Giant from attach routines

Assume floppy disk is not inserted when we have exhausted retries. This
significantly reduces booting time when there is broken floppy disk drive,
controller, cable, BIOS, etc.
When the floppy controller interface is correctly implemented, disk change
signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7.
However, there are many cases that the signal is unusable. Moreover, some
BIOS does not reserve the port at all. In those cases, the register may not
function.

Fix a couple of problems with the probe code when used with pnpbios
resources. When allocating 6 ports for a 4 port range isa code
returns an error. I'm not sure yet why this is the case, but suspect
it is just a non-regularity in how the resource allocation code works
which should be corrected. Use 1 as the ports size in this case.
However, in the hints case, we have to specify the length, so use 6 in
that case. I believe that this is also acpi friendly.
Also, complain when we can't allocate FDOUT register space. Right now we
silently fail when we can't. This failure is referred to above.
When there's no resource for FDCTL, go ahead and allocate one by hand.
Many PNPBIOS tables don't list this resource, and our hints mechanism also
doesn't cover that range. If we can't allocate it, whine, but fake up
something. Before, we were always bogusly faking it and no one noticed
the sham (save the original author who has now fixed his private shame).

MFp4: overhaul of resource allocation
Rather than have a twisty maze of special case allocations, move
instead to a data driven allocation. This should be the most robust

of 2 nor contiguous.
Also, make it less impossible that pccard will work. I've not been able

it wasn't until recently that I could test more than one allocation

This requires only one change to support. Rather than keying on the

This covers the same cases that the size of 2 would catch, but also

catches no other cases.

das@ has a ACPI bios that lists 0x3f0-0x3f1, 0x3f2-0x3f3, 0x3f4-0x3f5
and 0x3f7. fdc_isa_alloc_resource() didn't work right in this case
(it accessed FDOUT correctly due to an overflow of the first resource.
It accesed FDSTS and FDDATA incorrectly via the second resource (which
wound up accessing FDOUT and the tape register at 0x3f3) and badly for
the CTL register (at location 0x3f4). This is a minimal fix that just
'eats' the first one if it covers two locations and has an offset of
0. This confusion lead the floppy driver to think there'd been a disk
change, which uncovered a deadlock in the floppy/geom code which lead
to a panic. These changes fix that by fixing the underlying resource
problem, but doesn't address the potential deadlock issue that might
still be there.
This is a minimal fix so it can more safely be merged into 5 w/o risk
for known working configurations (hence the use of the ugly goto,
which reduces case 8 to case 6 w/o affecting cases 1-7). A more
invasive fix that will handle more ACPI resource list diversity is in
the pipeline that should kill these issues once and for all, while
staying within the resources that we allocate.

The long dead hand of the past has pushed forward useless bits in this

fixing the 'thread not terminated on detach' problem.
o dmacnt is no longer used now that we allocate at attach time. Remove
it from struct fdc_data.
o ISPNP was only ever set, but never tested. It used to be used for the
allocation routines to change how it allocated resources. Since that's
no longer necessary, retire the flag.
o ISPCMICA was only ever tested, but never set. GC it. This removes
a special case in determining the drive type. The drive type is
now set in fdc_pcmcia.c, so the hack isn't needed anymore. Sadly,
this isn't tested with a Y-E Data pcmcia floppy drive because there
are a number of other issues that preclude it from working.
o Fix ifdef for reading from the rtc. I'm of the opinion that this ifdef
should be moved into fdc_isa.c, but not today as ideally there'd be
other fixes to the probing of children. So now we just read it on
i386 ! pc98 (there's no #define for MACHINE_ARCH, just MACHINE, hence
this slightly inelegant kludge) and amd64. The PC98 exclusion likely
isn't meaningful since pc98 uses a different driver, but will be when
merging of the pc98 floppy code into this driver is complete (this is the
other reason I think this block of code belongs outside fdc.c).
All of these changes are safe to MT5.

Reserve the DMA memory at attach time, rather than at use. While
reserving it at use time is more miserly, low memory (< 16MB)
evaporates quickly on many systems, so there may not be any suitable
buffers available. This specifically doesn't use the newer, fancier
isa_dma_init to ease merging to 5.

For the moment, treat failures to attach floppy drives as non-fatal

When ISA_PNP_PROBE is called, it will return 0 when it finds a device,
ENOENT when there's no PNP ID for this device node, or ENXIO when there
is one, but it doesn't match.
In the nonPNP case (as most Alpha systems appear to be), we were
treating the error return as an error, when it should be have ignored
it. Version 1.9 properly ignored it, but the attach re-write of 1.10
introduced this logic error.

Fix _FDI drive type probing. The new fd child is not an ACPI device while
the old one is. Hence we need to evaluate the old one for _FDI since it

Rewrite of the floppy driver to make it MPsafe & GEOM friendly:
Centralize the fdctl_wr() function by adding the offset in
the resource to the softc structure.
Bugfix: Read the drive-change signal from the correct place:
same place as the ctl register.
Remove the cdevsw{} related code and implement a GEOM class.
Ditch the state-engine and park a thread on each controller
to service the queue.
Make the interrupt FAST & MPSAFE since it is just a simple
wakeup(9) call.
Rely on a per controller mutex to protect the bioqueues.
Grab GEOMs topology lock when we have to and Giant when
ISADMA needs it. Since all access to the hardware is
isolated in the per controller thread, the rest of the
driver is lock & Giant free.
Create a per-drive queue where requests are parked while
the motor spins up. When the motor is running the requests
are purged to the per controller queue. This allows
requests to other drives to be serviced during spin-up.
Only setup the motor-off timeout when we finish the last
request on the queue and cancel it when a new request
arrives. This fixes the bug in the old code where the motor
turned off while we were still retrying a request.
Make the "drive-change" work reliably. Probe the drive on
first opens. Probe with a recal and a seek to cyl=1 to
reset the drive change line and check again to see if we
have a media.
When we see the media disappear we destroy the geom provider,
create a new one, and flag that autodetection should happen
next time we see a media (unless a specific format is configured).
Add sysctl tunables for a lot of drive related parameters.
If you spend a lot of time waiting for floppies you can
grab the i82078 pdf from Intels web-page and try tuning
these.
Add sysctl debug.fdc.debugflags which will enable various
kinds of debugging printfs.
Add central definitions of our well known floppy formats.
Simplify datastructures for autoselection of format and
call the code at the right times.
Bugfix: Remove at least one piece of code which would have
made 2.88M floppies not work.
Use implied seeks on enhanced controllers.
Use multisector transfers on all controllers. Increase
ISADMA bounce buffers accordingly.
Fall back to single sector when retrying. Reset retry count
on every successful transaction.
Sort functions in a more sensible order and generally tidy
up a fair bit here and there.
Assorted related fixes and adjustments in userland utilities.
WORKAROUNDS:
Do allow r/w opens of r/o media but refuse actual write
operations. This is necessary until the p4::phk_bufwork
branch gets integrated (This problem relates to remounting
not reopening devices, see sys/*/*/${fs}_vfsops.c for details).
Keep PC98's private copy of the old floppy driver compiling
and presumably working (see below).
TODO (planned)
Move probing of drives until after interrupts/timeouts work
(like for ATA/SCSI drives).
TODO (unplanned)
This driver should be made to work on PC98 as well.
Test on YE-DATA PCMCIA floppy drive.
Fix 2.88M media.
This is a MT5 candidate (depends on the bioq_takefirst() addition).

Fix ACPI floppy enumeration for three types of divergent behavior.
* Some systems have _FDE and child floppy devices, but no _FDI. This seems
to be compatible with the standard. Don't error out if there is no _FDI.
Instead, continue on to the next device. The normal fd probe will take
care of this device.
* Some systems have _FDE but no child devices in AML. For these, add a
second pass that compares the results of _FDE to the presence of devices.
If not present, add the missing device.
* Some BIOS authors didn't read the spec. They use tape drive values for
all fdc(4) devices. Since this isn't grossly incompatible with the
required boolean value, use them. They also define the _FDE items as a
package instead of buffer. Regenerate the buffer from the package if it
is present.

fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> port
0x3f7,0x3f4-0x3f5,0x3f2-0x3f3,0x3f0-0x3f1 irq 6 drq 2 on acpi0
To do this, we find the minimum and maximum start addresses for the
resources and use them as the base for the IO and control ports.

- Use the new resource_disabled() helper function to see if devices are
disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
see if the device is disabled in the identify routine instead of in the
probe routine. This way if the device is disabled it is never created.
Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled". If this is a big problem, resource_disabled() can always be
changed to honor both names.

After some comments from bde, rewrite the loops to avoid turning the

pessimization. Now the loops are written in the more natural count-up
form.
Also, while being there, i made the logic in out_fdc() similar to the
logic in in_fdc(). The old implementation was a bit bogus anyway
since it first tested the DIO bit and only afterwards the RQM bit.
However, according to the description of the i82077, the DIO bit is
only guaranteed to be valid once the RQM bit is set. Thus, the old
implementatoin would have had the chance to misbehave on a controller
that is implemented in accordance with the i82077 description (but is
not bug-for-bug compatible).

such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

Long promised major enhancement set for the floppy disk driver:
. The main device node now supports automatic density selection for
commonly used media densities. So you can stuff your 1.44 MB and
720 KB media into your drive and just access /dev/fd0, no questions
asked. It's all that easy, isn't it? :)
. Device density handling has been completely overhauled. The old way
of hardwired kernel density knowledge is no longer there. Instead,
the kernel now implements 16 subdevices per drive. The first
subdevice uses automatic density selection, while the remaining 15
devices are freely programmable. They can be assigned an arbitrary
name of the form /dev/fd[:digit]+.[:digit:]{1,4}, where the second
number is meant to either implement device names that are mnemonic
for their raw capacity (as it used to be), or they can alternatively
be created as "anonymous" devices like fd0.1 through fd0.15,
depending on the taste of the administrator. After creating a
subdevice, it is initialized to the maximal native density of the
respective drive type, so it needs to be customized for other
densities by using fdcontrol(8). Pseudo-partition devices (fd0a
through fd0h) are still supported as symlinks.
. The old hack to use flags 0x1 to always assume drive 0 were there is
no longer supported; this is now supposed to be done by wiring the
devices down from the loader via device flags. On IA32
architectures, the first two drives are looked up in the CMOS
configuration records though. On PCMCIA (i. e., the Y-E Data
controller of the Toshiba Libretto), a single drive is always
assumed.
. Other specialities like disabling the FIFO and not probing the drive
at boot-time are selected by per-controller or per-drive flags, too.
. Unit attentions (media has been changed) are supposed to be detected
now; density autoselection only occurs after a unit attention. (Can
be turned off by a per-drive flag, this will cause each Fdopen() to
perform the autoselection.)
. FM floppies can be handled now (on controllers that actually support
it -- not all do these days).
. Fdopen() can be told to avoid density selection by setting
O_NONBLOCK; this leaves the descriptor in a half-opened state where
only a few ioctls are accepted. This is necessary to run fdformat
on a device that uses automatic density selection (since you cannot
autoselect on an unformatted medium, obviously).
. Just differentiate between a plain old NE765 and the enhanced chips,
but don't try more; the existing code was wrong and only misdetected
the chips anyway.
BUGS and TODOs:
. All documentation update still needs to be done.
. Formatting not-so-standard format yields unpredictable results; i
have yet to figure out why this happens. "Standard" formats like
720 and 1440 KB do work, however.
. rc scripts are needed to setup device nodes with nonstandard
densities (like the old /dev/fdN.MMM we used to have).
. Obtaining device flags from the kernel environment doesn't work yet,
thus currently only drives that are present in (IA32) CMOS are
really detected. Someone who knows the odds and ends about device
flags is needed here, i can't figure out what i'm doing wrong.
. 2.88 MB still needs to be done.

Another large patchset from Bruce.
Despite of a few cosmetic things like adding ``irritating silly
parentheses'' around all return values, this mainly improves FDC reset
handling by no longer gratuitously resetting the FDC all the time
(which causes it to lose the notion of the current track) but only in
case of errors, and it sanitizes the block and offset calculations in
fdstrategy() and fdstate(). Some additional cleanup added by me, in
particular the large switch in fdstate() now always uses return to
break out, and no branch falls off the end of the switch statement
anymore. Per Bruce's suggestion, removed M_NOWAIT from the malloc()s
to simplify things.

More cleanup when detaching. Clone device entries will now be
destroyed properly (otherwise bad things would happen after a clone
dev had been created, and the module was kldunloaded). Allocated
children that have not successfully probed are being deleted again
(otherwise fd0 and fd1 have always been allocated, even if only
fd0 was acutally present, and fd1 even survived kldunloading the
module).
Still, kldunloading leaves remnants of the previously existing devices
intact. Why doesn't it destroy all the devices? As a consequence,
since dev->descr now points into no longer allocated memory, the
system panics deep inside printf(9) when running devinfo(1) after
kldunloading the module. Ideas sought...
Also, when kldloading the module on a hints-populated isab0, this bus
somehow has already created an fdc0 entry (a dummy) so the load
attempt fails and will register fdc1 instead. What are those dummy
entries for? Loading the module from the bootloader works, and it
can be unloaded an re-loaded then later.

B_WRITE was bogusly defined as zero giving rise to obvious coding

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue. It is likely to write on your disk
where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.

Make the Y-E Data PCMCIA floppy of the Toshiba Libretto work under
-current. It doesn't work yet as stable as the 3.x/PAO version of the
driver does, however, i get occasional `FDC direction bit not set' and
other weird messages, but it basically works at least.
The old (defunct) #ifdef FDC_YE stuff has been eliminated completely
now, PCMCIA-FDC specific functions have been implemented differently
where needed.
Unfortunately, due to the fact that the traditional PeeCee FDC with
its funny non-contiguous register space (one register for WD1003
harddisk controllers is interleaved into the FDC register set), and
Peter's subsequent changes involving two different bus space handles
for normal FDCs, the changes required for the Y-E stuff are more
complex than i'd love them to be. I've done my best to keep the logic
for normal FDCs intact.
Since the Y-E FDC seems to lose interrupts after a FDC reset
sometimes, i've also replaced the timeout logic in fd_turnoff() to
generate an artificial pseudo interrupt in case of a timeout while the
drive has still outstanding transfers waiting. This avoids the total
starvation of the driver that could be observed with highly damaged
media under 3.x/PAO. This part of the patch has been revied by bde
previously.
I've fixed a number of occasions where previous commits have been
missing the encapuslation of ISA DMA related functions inside
FDC_NODMA checks.
I've added one call to SET_BCDR() during preparation of the format
floppy operation. Floppy formatting has been totally broken before in
3.x/PAO (garbage ID fields have been written to the medium, causing
`wrong cylinder' errors upon media reading). This is just black
magic, i don't have the slightes idea _why_ this needs to be but just
copied over the hack that has been used by the PAO folks in the normal
read/write case anyway.
The entired device_busy() stuff seems to be pointless to me. In any
case, i had to add device_unbusy() calls symmetrical to the
device_busy() calls, otherwise the PCMCIA floppy driver could never be
deactivated. (As it used to be, it caused a `mark the device busier
and busier' situation.) IMHO, all block device drivers should be
marked busy based on active buffers still waiting for the driver, so
the device_unbusy() calls should probably go to biodone(). Only one
other driver (whose name escapes me at the moment) uses device_busy()
calls at all, so i question the value of all this...
I think this entire `device busy' logic simply doesn't fit for PCMCIA
&al. It cannot be the decision of some piece of kernel software to
declare a device `busy by now, you can't remove it', when the actual
physical power of removing it is the user pulling the card. The
kernel simply has to cope with the removal, however busy the device
might have been by the time of the removal, period. Perhaps a force
flag needs to be added?
Upon inserting the card a second time, i get:
WARNING: "fd" is usurping "fd"'s cdevsw[]
WARNING: "fd" is usurping "fd"'s bmaj
I suspect this is related to the XXX comment at the call to
cdevsw_add(). Does anybody know what the correct way is to cleanup
this?

- Don't abuse the ivars pointer.. (!). Create real ivars and use the
proper access system. (the bus_read_ivar method)
- Don't add the children until attach() has successfully grabbed the
hardware, otherwise there are potential leaks if attach fails.

Add a truely evil workaround (hack!) for some unfortunate BIOS
programming practices. It seems that newer fdc chips have an
alternative way of setting the transfer speed (including high speed
modes for floppy tape) that doesn't use the control register (which
we don't support - we use the old way only). So, they (the BIOS
programmers) sometimes leave out the 0x3f6 control register from
the PnP ports descriptor(!!). "Hey, it works with windows, so
what's the problem?" :-( Anyway, this hack tries to compensate
for that. This was discussed with dfr (who did the pnp attachment).

Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition. eisa, isapnp and pccard* are
not yet using the new resource manager. Once fully converted, all drivers
will be loadable, including PCI and ISA.
(Some other changes appear to have snuck in, including a port of Soren's
ATA driver to the Alpha. Soren, back this out if you need to.)

Add a prioritization field to the devstat_add_entry() call so that
peripheral drivers can determine where in the devstat(9) list they are
inserted.
This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed. The devstat version number has been incremented as
well to reflect the change.
This sorts devices in the devstat list in "more interesting" to "less
interesting" order. So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.
The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers. For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.
Also, move the checkversion() call in vmstat(8) to a more logical place.
Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it. Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.

It differs from a normal floppy in that you must use PIO rather than

To enable this, you must add options "FDC_YE" to your kernel. I don't
have a machine that has a floppy and a pcmcia slot to test to make
sure that this doesn't impact normal floppy units, so I've left this as

Fixed error handling:
- Call isa_dmadone() whenever necessary to stop DMA and/or free bounce
buffers. Undead DMA corrupted the malloc freelist fairly consistently
in the following configuration: SLICE kernel, 2 floppy drives, no disk
in fd0, disk in fd1.
- Don't call fdc_reset() from fd_timeout(). Doing so gave an "extra"
interrupt which was usually misinterpreted as being for completion
of the next FDC command; the interrupt for completion of the next
FDC command was then usually misinterpreted... There were further
complications for interrupts latched by the soft-spl mechanism so
that they were delivered after all the h/w interrupts went away.
This caused at least wrong head settle delays and may be why the
FreeBSD floppy driver seems to munch floppies more than most floppy
drivers. The reset was unnecessary anyway in cases that didn't have
the bug described next, since is was repeated a little later for
the IOTIMEDOUT state. The state machine has complications to handle
resets correctly, so just use it.
- Don't call retrier() from fd_timeout(). The IOTIMEDOUT state needs
to be processed next, and it isn't valid to set to that state if
retrier() has aborted the current transfer. Doing so caused null
pointer panics after the previous bug was fixed.
Improved error handling:
- If an i/o is aborted, arrange to reset in the state machine before
doing the next i/o. New fdc flag for this. This fixes spurious
warnings and lengthy busy-waiting for the next i/o.
- Split STARTRECAL into RESETCOMPLETE and STARTRECAL and only check
for the results from reset if we actually reset. This fixes spurious
warnings for other paths to STARTRECAL. [Oops, it may break reset
handling for motor-off resets.]
Cleanups in fd_timeout():
- Renamed to fd_iotimeout() to make it clearer that it is only used
for i/o.
- Don't handle the bp == 0 case. This case can't happen for i/o.
- Don't check for controller-busy. We know it must be.
- Don't print anything. retrier() already prints too much for normal
errors.
- Fudge the state differently so that the state machine advances
fdc->retry and the status is invalid (perhaps this should fudge a
valid state like the one for WP).
- Style fixes.

Fixed error handling after a seek error that can't happen. When the
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case. This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested. The fix is simply to arrange to reset the state
machine.
Corruption of the buffer queue seems to only have been a problem in the
floppy driver. Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order. Dequeueing breaks it anyway.

Enable the FIFO on enhanced floppy controllers. This reduces the
number of dma overruns/underruns for systems under heavy dma load.
As a side effect, broken enhanced floppy controllers that sometimes
don't detect dma overruns/underruns will give less errors.

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)

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);

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.)

Add a class field to devconf and mst drivers.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.

Finally implement support for the `lsdev' program. The controller is

Also reformat everything to fit into 80 columns again.
Changed my mind wrt. error reporting for a write-protected drive and
an open() with write intent; ENXIO has been too weird, now return EIO.
Some portions of the code need to be rewritten to use tprintf()

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.)

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).

Fixed the problem where the floppy has incorrectly failed probing
when the drive had been left on a cylinder > 67 after kernel boot. The
most common case for this is booting a kernel that is located on
the inner cylinders of a floppy.
Also removed all occurences of spinwait(), replaced by DELAY.
Nuked a return line saying nothing, this might make Bruce happy 8^)

Updated driver to the 1.1.5 version:
date: 1994/05/22 12:35:38; author: joerg; state: Exp; lines: +6 -6
First round of floppy changes. Try making `fd' more robust.
New features:
. ioctl command for setting the drive type (density etc.); restricted
to the super-user
. ioctl for getting/seting `drive options'; currently only option
is FDOPT_NORETRY: inhibit the usual retries; used when verifying
a newly formatted track
Fixes:
. function prototypes
. made all internal functions `static'
. cleaned up & corrected .h files
. restructured, to make the chaotic function sequence more rational
. compiled with -Wall, and cleared all warnings
. introduced a mirror for the (write-only) `digital output register',
to avoid the current kludge
. device probing completed by seeking/recalibrating, and looking
for track 0 being found
. holding the controller down in reset state while it is idle (and
thus saving allot of headaches)
. make requests fail that are not a multiple of the (physical)
sector size
. removed the fixed physical sector size (512 bytes), allowing for any
size the controller could handle (128/256/512/1024 bytes)
. replaced some silly messages
. fixed the TRACE* macro usage, debugging reports should be complete
now again (debugging output is HUGE! though)
. removed fd_timeout for SEEK command; seeks are always reported by
the controller to succeed, since the `success' only refers to the
controller's idea of success - there is no hardware line to tell about
the seek end (other than the `track 0' line)
. catch SENSEI's that report about a `terminated due to READY changed'
status - could happen after a controller reset
. converted ``hz / <something>'' divide operations to divisors that are
powers of two, so gcc can optimize them into shifts
. write/format operations are checked against a write-protected medium
now *prior* starting the operation
. error reports of `invalid command' and `wrong cylinder' will cause
shortcuts in the retrier() now
. fixed a bug in the retrier() causing bogus block numbers to be reported
. fdformat() does care for errors now
Known Bugs:
. no attempts have been made (yet) to improve the performance
. sometimes, bogus ``seek/recalib failed'' messages are logged; this
is still a bug in the driver, but it's not harmful since it's
usually caught by the retrier()

I think removing FINDWORK would make things clearer.
Nothing much is going to start work on the next item. However, it is
pointless to continue processing the queue for the same unready drive.
Aborting all reads and trying harder to perform all writes would be
better.

The fd driver reported the wrong cylinder/head/sector numbers after an
error (ST3 is only valid after a sense-drive command), and didn't report
fs block numbers (diskerr was not used).
There was an old problem with writes to block fd devices. Try this:
1. write protect floppy in fd0.
2. tar cf /dev/fd0a /dev/null. Repeat a few times. Later writes tend to
terminate earlier.
3. un-write protect floppy.
4. repeat step 2. The writes tend to return 0, 2048, 4096, ... and then
succeed.
This was caused by a bug in vfs__bios.c. (The bug is fixed in NetBSD's
vfs_bio.c.) fd.c sets bp->b_resid to nonzero after an error. vfs__bios.c
was not initializing bp->b_resid. This causes some writes to terminate
early (e.g., writes to block devices; see spec_write()).
Related funnies:
1. Nothing tries to write the residual bytes.
2. The wd driver sets bp->b_resid to 0 after an error, so there's no
way anything else could write the residual bytes.
3. I use the block fd device for tar because the raw device seemed to
have more bugs long ago, and because it ought to be able to handle
buffering more transparently (I don't want to have to know the
device size). But spec_write() always uses the size BLKDEV_IOSIZE
== 2048 which is too small. For disks it should use the size of
one track (rounded down to meet the next track boundary or the i/o
size). Here it would help if the DIOCGPART ioctl worked. But
DIOCGPART is not implemented for floppies, and the disk size is
ignored except for partitions of type FS_BSDFFS.

Removed $Log$ section and patch kit headers. And here is the full
message for Bruces changes:
>From: bde@kralizec.zeta.org.au (Bruce Evans)
>Subject: fixes for fd driver
I think I've fixed some bugs in the 0.2.4 fd driver.
1. The main cause of hangs was that there was no timeout for seeks. So
attempting i/o with no floppy in the drive hung iff a seek was required.
2. Opens of unattached drives were allowed. The kernel usually paniced
soon after due to a bad pointer.
3. Some timeout functions ran at splclock() instead of splbio(). This
may not have mattered.
4. The state machine was left in a funny state after a timeout.
5. Some function headers were new-style.
6. I picked up some code posted the other day to implement label ioctls.
Now `disklabel fd0' works. See a comment for how to modify conf.c.
