Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.
Inspired by PR #6090, from Matt Jacob.

controllers (including SCSI id 7 on the 2100/3100).
- On the pmax (2100,3100) set the host SCSI id to 6.
- Move disk and tape config for the second ASC controller from the GENERIC
config file to scsi.pmax so all configurations can use the second
controller.
* dec_5100.c: sysconf, interrupt, and motherboard (drain writebuffer)
support for 5100.
* support for hardware kludge in 5100: sii DMA buffer is hardware
padded to alternate 32-bit words, not alternating 16-bit halfwords.
* 5100 has no framebuffer, console is wired to serial port 0.
With ibus support, boots as far as exec'ing init, and hangs.
as pmax/dev/findcons.c:
* Follow the same logic: look for the device the PROM is using.
* If it's a framebuffer and we don't have a driver for it, try other
* framebuffers in PROM search order.
* If no match found, warn user and fall over to serial console.
* if no serial console found, go back to PROM.
Rework tc/scc.c attach routine to give cleaner initialization semantics.
Prune out old 'braindamage' code.
* Do rcons output properly, using cn_tab->cn_dev which points
at rcons cdevsw entrypoints.
* The pmadx console code was using keyboard (serial) device
(major,minor) for raster consoles with special code in the keyboard
drivers to catch output intended for consoles, pull it off the device
queue, and print them via cnputc().
Ifdef out RCONS_BRAINDAMAGE.
* Other minor cleanup to pmax scc driver.

The 150ms delay is verified to work on 3100s on both kinds of mice.
Fix cursor sprite for X11 startup/exit:
* add cursor on/off functions.
* Default cursor state is off (for framebuffer console).
* Turn off cursor in each driver's xxxCursorInit() entrypoint.
* Turn on cursor at the end of each driver's xxxLoadCursor() entrypoint.

works with X11R5 servers shipped with NetBSD 1.3.
* Add code to query CDs for size, from MI scsi cd.c. Use it on CDs.
* Set C partition size for CDs. 4.4bsd/pmax code only set `a' partition
size and required users to mount `a' partition, breking raw-device
access like "disklabel rz?".
* Avoid possible divide-by-zero call to howmany() from rzstart(),
on removable media that aren't ready at device-open time.
Verified to work on rrz42.
until a proper fix is available:
Perpetuate the 4.4bsd design even further. Change keyboard-driver
open routines to check for an active raster console. If active, set the
keyboard struct tty's t_winsize from the rcons t_winsize on first open.
See pr 4438 for remaining problems and discussion of a complete fix.
* add includes for sys/dev/scsipi headers.
* cut-and-paste mode_sense and disk-geometry sense code from sd.c,
with name changes sd -> rz.
* Write `rz_command()' to send SCSI sense commands based on
existing rz size-sensing code.
* get geometry info with page 4 and page 5 mode sense.
* use resulting geom info for default label, fake label, and when
using ultrix labels. (ultrix labels have no geometry info).
Fixes incrrect-label bugs with using sysinst to install onto
Ultrix-labelled disks.
* Check for a disklabel matching the known values in an install diskimage.
If found, update incore disklabel's RAW_PART with the size reported
by the disk, clobbering the size used by vnd(4).*
* If geometry info is bogus or /missing, supply a fake geometry
(as in sd.c). Saves readdisklabel() and sysinst from divide-by-zero errors.
* lint: RAWPART -> RAW_PART.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
Add DDB interface to /sys/arch/mips/mips..
Rework heuristic stack traceback to work with DDB.
Add hooks to print exception log from DDB.
Add hooks from pmax console drivers: call Debugger()

Delete 'needs-flags' from dc.c. GC obsolete uses of NDC, "dc.h".
(The operator-precdence changes in 1.11 were pulled up in rev 1.14).
* If the chip asserts a SCSI-bus error (SII_BER) in sii_intr,
reset the SII_BER bit instead of ignoring it.
XXX SII_BER May need checking and resetting elsewhere.
Fixes broken blitting from rcons.
* Put back old 4.4bsd range test on cursor movement. 1.2 code is broken.
* Disable screensaver, it reportedly never comes back on properly.

data past the struct device data actually allocated. This does not appear
to have caused a problem in the past, but causes a problem with the new

serial consoles to the 1.2 branch. Includes:
* dynamically allocated new-config softc
* remove dependencies on Decstation CPU type, use flags in softc instead.
* pass in values for softc flags (q.v.) from parent-specific attach code
* #ifdef out rts/cts flow control support until it's known to work on

* redo initialization of serial consoles (needs more work).
The Lite2 changes include:
* Remove the last vestiges of high-bit-set-means-delay for output chars.
* Handle the 2100/3100 having partial modem control on line 2 only,
whereas the 5000/200 has modem control signals on lines 2 and 3.
* Add RTS/CTS support for lines 2 and 3 on a 5000/200.
* Add more s = spltty(); splx(s); where needed but not present.
as a console, initalize as white-on-black so console messages are legible.
(Sean Davidson reports that rcons still messes up the display, perhaps
due to using the wrong pixel depth).
1. Start at the specified entry instead of entry 0.
2. Use the blue value instead of the green when setting the blue color entry.
3. Don't use the starting index again for storing the saved entry - the cmap
pointer was previously initialized using the starting index. This fixes
a hard hang on the maxine when console output is done after calls to
set the color map (usually by the X server).
* Add interrupt handler for 3MIN, where we cannot disable TC slot interrupts.
* Change mfbinit() signature to match other (pmax) TC framebuffer init
routines.
* TODO after 1.2: add {cfb,mbf,sfb}var.h. Declare init functions there.
message-in. The remaining transfer count restored when a device is
reselected needs to be saved. The saved value is needed to compute
the number of bytes transferred if another disconnect occurs. This
fixes a random read data corruption that occurs on certain disks that
may disconnect more than once in the middle of a DMA transfer.
Show proper inquiry data when version >= 1, not <= 1 (SCSI-2 devices

configure properly. Also fix devices with TurboChannel and mainbus
attachments so they will work if no TurboChannel was configured.
Fix clock.c for a missing variable if not including NTP support.
Also remove some extraneous includes files or use the right ones.
configure properly. Also fix devices with TurboChannel and mainbus
attachments so they will work if no TurboChannel was configured.
Fix a panic when the dtop keyboard handler receieves a character
before the device has been opened.
update the 4.3bsd/Ultrix-compatible qvss-style mmap'ed framebuffer/input-event
code to use mips_round_page() et.al., not pmax_round_page().
Add explicit "int" return types to functions. Add prototyped forward
declarations.
Fix the the definitions of dtop cdevsw entry point functions to match
their declarations. Add explicit "int" declarations to functions.
Add prototyped declarations for all local functions.
Return zero from dtopstop().
Include the external declarations from dtopvar.h.
Add prototypes to (most of) src/sys/arch/pmax/pmax. (The un-protytyped
parts still have pending merges with the Pica port.)
Fix splx() glitches in pmax/clock.c.
Delete old cpu/fpu identification from pmax/autoconf.c, use r4400/r4600/idt
aware code from Pica port, now in mips/mips/mips_machdep.c.
Delete unused multi-CPU autoconfiguration code; NetBSD/pmax does not
support decsystem 5800s anyway.
Update the pmax SCSI drivers (rz and tz) to use <machine/conf.h>.
Fix the driver entry points to have the correct signatures -- add
"ioflag" args to read() and write(), add "struct proc *p" arg to
open and close.
Stop using __BDEVSW_DUMP_OLD_TYPE, and update the rzdump and tzdump
entry points to have the correct, MI signatures.
NB: this is just syntactic sugar: both the caller and the dump entry
points ignore the additional args, and do exactly what they did before.
This must be fixed before using dump entry points in non-pmax drivers
(e.g., the MI scsi code).
add prototyped declarations for the callbacks which add old-style
(4.4bsd/pmax conf.old) SCSI controllers, and which configure SCSI slaves
on such controllers.
rewriting the SII driver to work with the MI scsi would be a better option,
if time were available, and the MI scsi code supported SCSI controllers with
an 8k upper bound on transfers.
Add prototyped declarations for scsiGroup0Cmd and scsiGroup1Cmd.
Add prototype declarations for scsiPrintSense. Cut the inqiury-response
pretty-printer from tz.c and rz.c and paste it in as scsiPrintInquiry.
-Wall -Wmissing-prototypes:
Add prototypes.
Fix printf() format strings (%x vs pointer-arg, %x with a long int).
Fix a possibly-uninitialized shadowing local variable "resid" in tzdone().
include <sys/systm.h> to get prototypes for printf() and bcopy().
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
based on "#ifdef MELLON": examine the framebuffer dimensions in the
fb softc, and initialize the x-axis offset appropriately.
User-level changes to (e.g.) an Xserver are still needed to work
on an SFB.
The dtop driver no longer requires the "needs-count" flag.
Fix a panic in boot-time interrupt establish. The "generic" pmax
interrupt-establish code assumes that all interrupt args are new-config
device structs accessed via a struct cfdriver. Make it so.
independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
* Change the tc autoconfiguration tables to use a struct tc_attach_args
instead of the ad-hoc structure.
* Change all pmax device drivers to use a `struct confargs' that's
assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
Devices that can be present on a TC or as ioctl asic/mainbus builtins
use the same `struct confargs'.
* Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
an old, now-obsolete sys/arch/alpha snapshot.
* Update the comments and debugging code in interrupt handlers to
be consistent with the machine-independent TC support.
Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.

- New metrics handling. Metrics are now kept in the new
`struct disk'. Busy time is now stored as a timeval, and
transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.
For usage and architectural details, see the forthcoming disk(9) manual
page.
Eliminate pmax/tc/tc.h. Use dev/tc headers for pmax port. Change pmax TC
autoconfig tables to use structs (mostly) compatible with dev/tc/tcvar.h.
Move TC console search to tc.c.
with pk:
Use dev/rcons/files.rcons in the pmax config file.
Use "rasterconsole" as the tag in pmax/conf, and modify the pmax
framebuffer pseudo-device drivers (fb and rcons) to us rasterconsole.h and
RASTERCONSOLE for compile-time configuration of the rcons pseudo-device.
Modify the pmax rcons pseudo-device driver to initialize a little-endian,
QVSS-compatible font (set its ascent, and set the rconsole structure to
point to that font) before calling rcons_connect().
Tested on a cfb. The ascent may be wrong (or at least, not be aligned with
the hw cursor sprite) on a 3100.
