Define the correct return lengths for a number of ioctls.
Add ioctls VINUM_CHECKPARITY and VINUM_RESETPARITY, still to be fully
implemented.

vinum to dereference a null vp if device nodes were
missing.

check_drive: Don't take a drive down if it's only referenced.
read_drive: Remove unused variable.
get_empty_volume: initialize plexes to -1 (not allocated)
remove_drive_entry:
Remove recurse parameter (there's nothing below a drive in the hierarchy).
Use remove_sd_entry to remove sds, don't do it ourselves.
Log errors, don't throw rude remarks.
remove_plex_entry:
Don't use plex->subdisks as a loop limit, it gets changed in the
loop. This caused some removals to only remove half the subdisks.
Change logging of some "impossible" situations.
remove_volume_entry:
Use remove_plex_entry to remove plexes, don't do it ourselves.
update_sd_config:
Use set_sd_state to do the work.
will have to mknod yourself for now.

on the way.
I386_BUS_SPACE_IO. Compiles now on the Alpha, but likely will not

work. Be more verbose when one cannot allocate IRQ, et al since this
is a common configuration problem. The cards have the IRQ soft wired
into their BIOS and do not try to do collision detection. This can
cause problems when this IRQ is the same as another card/device.
The PNP hasn't been tested. My PNP board is in a deployed system.
I'll sneak in testing of it sometime later. I've been able to mount
the 3.3R cdrom that arrived today and access files off it.

Added eof handling for unlabeled partitions.

- Split out the prototypes, externs and struct decls from if_epreg.h into
if_epvar.h.
- Add support for MCA based Etherlink III (3c529) devices.
None of this code is used right now; the old if_ep driver is still
in place and used.
I will eventually get around to converting if_ep_isa.c to newbus once I've
had a talk with Peter and DFR about the DEVICE_IDENTIFY() method.
I have tested this code on my PS/2. It works. I would like EISA and ISA
testers since my example hardware hasn't arrived yet.
Add:
dev/ep/if_ep.c optional ep
dev/ep/if_ep_isa.c optional ep isa
dev/ep/if_ep_eisa.c optional ep eisa
dev/ep/if_ep_mca.c optional ep mca
dev/ep/if_ep_pccard.c optional ep card
to sys/conf/files
Remove:
i386/eisa/3c5x9.c optional ep
i386/isa/if_ep.c optional ep
from sys/i386/conf/files.i386
PCCARD testers wanted!
I will switch off and cvs rm the old driver in favor of this copy once
I've had positive feedback or have the hardware to verify that it works.

Add a slightly different safetybelt under nostop for tty drivers.
Add some missing FreeBSD tags
fields in struct cdevsw:
d_stop moved to struct tty.
d_reset already unused.
d_devtotty linkage now provided by dev_t->si_tty.
These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.
The changes in this patch consist of:
initialize dev->si_tty in *_open()
initialize tty->t_stop
remove devtotty functions
rename ttpoll to ttypoll
a few adjustments to these changes in the generic code
a bump of __FreeBSD_version
add a couple of FreeBSD tags
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.
This does not open any security hole, because the bpf core isn't loadable
The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.
Add a couple of missing FreeBSD tags.

Enhance MIRROR code. Add a few more sanity checks and implement
a zone-based disk selector to make use of both disks when reading.
Also implement a read fail-over. If a read error occurs on one
disk, the I/O is retried on the other.
NOTE: CCD's mirroring support cannot deal with write errors properly
in regards to recovery, meaning that 'old' data under a write error may
be read non-deterministically if you reboot after a write error, and CCD
certainly cannot deal with a disk changeout. And it still can't. Use
vinum if you are really serious about mirroring. CCD basically just
implements a poor-man's mirror.
sum the total amount of I/O issued to determine when all the I/O
has completed. This fails when the EOF boundry occurs in the middle
of an I/O. Using cbp->cb_buf.b_bufsize works better.
there are stubs compiled into the kernel if BPF support is not enabled,
there aren't any problems with unresolved symbols. The modules in /modules
are compiled with BPF support enabled anyway, so the most this will do is
bloat GENERIC a little.
The lun is not incremented in the ata-disk driver when ATA_STATIC_ID
is not defined, thanks to Kenneth Wayne Culver <culverk@wam.umd.edu>
for finding that one.
PHK pointed at the & problem in atapi-cd in devstat_end_transaction_buf.
Too little sleep I guess...
Phase 1) move the driver
Phase 2)
Phase 3) Profit, by splitting the driver into smaller files like
bktr_tuner, bktr_card, bktr_audio, bktr_<osname>
making it easier to maintain and understand.
declaration for the interface driver from "foo" to "if_foo" but leave the
declaration for the miibus attached to the interface driver alone. This
lets the internal module name be "if_foo" while still allowing the miibus
instances to attach to "foo."
This should allow ifconfig to autoload driver modules again without
breaking the miibus attach.
It been awhile since the last major update, as a benefit there
are some cool things in this one (and new bugs probably :) )...
The ATA driver has grown "real" timeout support for all devices.
This means that it should be possible to get in contact with
(especially) lost ATAPI devices. It also means that the ATA
driver is now usable on notebooks as it will DTRT on resume.
An experimental hack at utilizing the Promise66's at UDMA66 is
in there, but I cant test it. If someone feels like sending
me one, give me a ping.
The ATAPI DMA enableling scheme has been changed, also better DMA
support for the Aladdin chipset has been implemented for ATAPI
devices. Note that the Aladdin apparently only can do DMA reads
on ATAPI devices, and the Promise cant do ATAPI DMA at all.
I have seen problems on some ATAPI devices that should be able
to run in DMA mode, so if you encounter problems with hanging
atapi devices during the probe, or during access, disable DMA
in atapi-all.c, and let me know. It might be nessesary to do this
via a "white list" for known good devices...
The ATAPI CDROM driver can now use eject/close without hanging and
the bug that caused reading beyond the end of a CD has been fixed.
Media change is also handled proberly. DVD drives are identified
and are usable as CDROM devices at least, I dont have the HW to
test this further, see above :).
The ATAPI tape driver has gotten some support for using the DSC
method for not blocking the IDE channel during read/write when
the device has full buffers. It knows about the OnStream DI-30
device, support is not completed yet, but it can function as a
primitive backup medium, without filemarks, and without bad media
handeling. This is because the OnStream device doesn't handle this
(like everybody else) in HW. It also now supports getting/setting
the record position on devices that supports it.
Some rather major cleanups and rearrangements as well (cvs -b diff
is your freind). I'm closing in on declaring this for beta code,
most of the infrastruture is in place by now.
As usual USE AT YOUR OWN RISK!!, this is still alpha level code.
This driver can hose your disk real bad if anything goes wrong, but
now you have been warned :)
But please tell me how it works for you!
Enjoy!
