for selecting unit). Instead, use the resource hints mechanism.
One unfortunate situation here is that there is no resource_quad_value
function- which is what I needed for WWN boot time replacement. Worse-
you can't store the hint as just plain
hint.isp.0.nodewwn="0x50000000aaaa0001"
because this gets interpreted as an int- incorrectly because it can't
be converted to an int. I can't even get this as a string. To work
around this particular case for nodewwn && portwwn setting, this
rather grotesque form will be used:
hint.isp.0.nodewwn="w50000000aaaa0001"
hint.isp.0.portwwn="w50000000aaaa0002"
At the same time, if we have no hinted WWN, set the default WWN (which, btw,
gets overridden if the card has valid NVRAM, which is usual) to
0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).
Eliminate more printf's and replace them either with device_printf or
isp_prt calls.
ones where we have a CAM path) and replacing them with calls to isp_prt.,
Eliminate isp_unit references- we no longer have an isp_unit- we now
have an isp_dev that device_get_unit can work with.

Add the 'virtual nulmodem driver'
Particularly useful for debuging kernels using vmware.
If your name is Bruce evans and you are a WIZ at tty interfaces,
then you should probably rip this to shreds and offer lots of suggestions and
patches. I've been using this since 4.0-CURRENT and it's never caused
problems but I'm sure I got something wrong. This is similar to the pty/cty
device driver except that both sides are ttys. Even minor numbers
are side A and odd minor numbers are side B.
Work needs to be done regarding what happens to the other side when you
close a node.
to use with vmware, configure vmware to redirect COM2 out to side A of one
of these and boot a kernel with teh gdb remote port set to sio1.
AFTER dropping into the gdb kernel debugger in your test kernel,
fire up gdb with it's remote port pointing at the appropriate side B.
To catch all console output, you can boot the vmware kernel with a serial
console, (COM1) similarly redirected to a nulmodem, and use 'tip' to observe it.
This is practically unaltered since pre 4.0 days except for
changes made along the way needed to make it compile, so any suggestions
or offers of total rewrites will be listenned to :-)
handle read and write requests for widths of multiple bytes. This
can be used to read 16-bit battery status registers for example.
- Remove some unused variables and #if 0'd debugging cruft.
- Don't complain about a GPE query that fails due to AE_NOT_FOUND if the
query method was _Q00.
from a BIF, use the size of the destinatino buffer, not the length of the
string to determine where to put the nul char. As a side effect, the
old code would truncate the string by one character while it was possibly
overflowing the buffer.
o Allocate memory mapped by pcic even when not used for ncv.
This is for PC-Cards which needs offset, because I/O space should not be
used by other devices.

If you ever want to run midi(4) out of the giant lock, uncomment
MIDI_OUTOFGIANT in midi.h. Confirmed to work for csamidi with WITNESS
and INVARIANTS.
- midi_info, midi_open and seq_info are now tailqs, allowing arbitrary
numbers of devices to be configured.
- Do not send an active sensing message to reset midi modules.
- Clone /dev/sequencer*. /dev/sequencer0 and /dev/sequencer are generated
upon initialization.
- Convert to a more efficient queueing implementation.
- Don't allocate command buffers on the fly; simply work from a
static pool.
- Add a control device interface, for later use.
- Handle controller overload better as a consequence of the
improved queue implementation.
- Add support for the XPT_GET_TRAN_SETTINGS ccb, and correctly
set the virtual SCSI channels up for multiple outstanding I/Os.
- Update copyrights for 2001.
- Some whitespace fixes to improve readability.
Due to a misunderstanding on my part, previous versions of the
driver were limited to a single outstanding I/O per virtual drive.
Needless to say, this update improves performance substantially.
o Offset and period in synch messages and width negotiation should be
done for per target not per lun. Move these from *lun_info to
*targ_info.
o Change in handling XPT_RESET_DEV and XPT_GET_TRAN_SETTINGS .
o Change CAM_* xpt_done return values.
o Busy loop did not timeout. Change this to timeout as original NetBSD/pc98.

attached and ifconfigable. The card doesn't interrupt yet.
Also, move towards bus space by introducing new macros/inline
functions which make such a move much easier than before.
These inline functions are setup now to work around an IBM EtherJet
pccard cardbus bridge incompatibility. The card works in 8 bit mode,
but not in 16-bit mode when it is connected to a cardbus bridge for
reasons unknown. The Linux driver also has a similar workaround in
it.
Future work will include making the above workaround runtime
conditional rather than compile time conditional, as well as fixing
the interrupts in pccards and converting it to bus space.
for the ICB firmware options meant- *I* had taken it to
mean that if you set it, Node Name would be ignored and
derived from Port Name. Actually, it meant the opposite.
As a consequence- change ICBOPT_USE_PORTNAME to the
define ICBOPT_BOTH_WWNS- makes more sense.
Fix wrong input bitmap for MBOX_DUMP_RAM command. Call
ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD
control command (so outer layers can run a mailbox command
directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so
outer layers can understand response queue entries we
might not know about.
- Use pci_get_powerstate()/pci_set_powerstate() in all the other drivers
that need them so we don't have to fiddle with the PCI power management
registers directly.
- Use pci_enable_busmaster()/pci_enable_io() to turn on busmastering and
PIO/memory mapped accesses.
- Add support to the RealTek driver for the D-Link DFE-530TX+ which has
a RealTek 8139 with its own PCI ID. (Submitted by Jason Wright)
- Have the SiS 900/National DP83815 driver be sure to disable PME
mode in sis_reset(). This apparently fixes a problem on some
motherboards where the DP83815 chip fails to receive packets.

Use the target offset rather than the target Id to reference
the untagged SCB array. The offset and id are identical save
in the twin channel case. This should correct several issues
with the 2742T.
Set the user and goal settings prior to setting the current
settings. This allows the async update routine to filter out
intermediate transfer negotiation updates that may be less
than interesting. The Linux OSM uses this to reduce the amount
of stuff printed to the console.
aic7xxx.seq:
Correct an issue with the aic7770 in twin channel mode.
We could continually attempt to start a selection even
though a selection was already occurring on one channel.
This might have the side effect of hanging our selection
or causing us to select the wrong device.
While here, create a separate polling loop for when we
have already started a selection. This should reduce
the latency of our response to a (re)selection. The diffs
look larger than they really are due to some code rearrangement
to optimize out a jmp.
aic7xxx_freebsd.c:
Use the target offset rather than the target Id to reference
the untagged SCB array. The offset and id are identical save
in the twin channel case. This should correct several issues
with the 2742T.
aic7xxx_inline.h:
Get back in sync with perforce revision ID.
aic7xxx_pci.c:
Identify adapters in ARO mode as such.
Ensure that not only the subvendor ID is correct (9005)
but also that the controller type field is valid before
looking at other information in the subdevice id. Intel
seems to have decided that their subdevice id of 8086
is more appropriate for some of their MBs with aic7xxx
parts than Adaptec's sanctioned scheme.
Add an exclusion entry for SISL (AAC on MB based adapters).
Adapters in SISL mode are owned by the RAID controller, so
even if a driver for the RAID controller is not present,
it isn't safe for us to touch them.
userland tool:
Use the vfs.devfs.generation sysctl to test for devfs presense
(thanks phk!) when devfs is active it will not try to create the
device nodes in /dev and therefore will not complain about the
failure to do so.
Revert the change in the #define for VINUM_DIR in the kernel
header so that vinum can find its device nodes.
Replace perror() with vinum_perror() to print file/line when
DEVBUG is defined (not defined by default).
kernel:
Don't use the #define names for the "superdev" creation since
they will be prepended by "/dev/" (based on VINUM_DIR), instead
use string constants.
Create both debug and non-debug "superdev" nodes in the devfs.

remove_sd_entry() to:
Simplify (hopefully) it by moving all error returns closer to
the beginning of the function.
Return an error when "Error removing subdisk %s: not found in
plex %s\n" would have been reported, as I doubt that we are "OK"
after printing that error message.
Adding make_dev() and destroy_dev() calls in (hopefully) the right
places.
This is done by calling make_dev() in each object constructor and
caching the dev_t's returned from make_dev() in each struct
'subdisk'(sd), 'plex' and 'volume' such that the 'object'_free()
functioncs can call destroy dev.
This change makes a subset of the old /dev/vinum appear under devfs.
Enough nodes appear such that I'm able to mount my striped volume.
There may be more work needed to get vinum configuration working
properly.
