- v2 openprom disk boot generates "/sbus/esp/sd@3,0" which we translated
into "/sbus@0,0/esp@0,0/sd@3,0"... this caused esp.c to reject
the bootpath because it was looking for sbus slot/offset 0,0.
changed the code to generate "/sbus0/esp0/sd@3,0" to fix this
panic.
- when generating fake boot paths, generate them with unit numbers
rather than slot/offsets (thus, /obio@0,0 becomes /obio0, as
does vmel and vmes).
- fixed up comments to reflect these changes
tested new code on: 4/280 (diskless), 4/360 (diskless), 4/360 ("xd" disk),
4/370 (scsi disk), ss1 w/v1 openprom (diskless),
ss1 w/v1 openprom (scsi disk), ss2 w/v2 openprom (diskless),
ss2 w/v2 openprom (scsi disk).
"struct pmax_fbtty". Remove most of its fields, since the fields
in the struct fbinfo render most of them unecessary, and the pmax
now uses rcons anyway. Moe the lk-201 keycode definitions to lk201.h,
so rcons can use them too.
to "kn01_<func>", to avoid confounding a model name (PMAX) with the name of the
entire port (pmax).
Change the signature of interrupt-handlers to take a void *
(a pointer to the softc) and return an int (indicating spurious
interrupts or other conditions.)
Pass softc pointers to the scsi and ethernet kn01 (DS_PMAX) drivers,
rather than having unit numbers wired into the base-level interrupt
handler.

Move consinit() from here to cpu_cons.c.
Eliminate the old old pmax-specific console driver, whcih didn't
know about vnodes. Use sys/dev/cons.c instead.
Delete the old 4.4BSD/pmax TURBOChannel probe routines and ROM-to-driver
name-mapping functions.
"struct pmax_device" to avoid conflict with <sys/device.h>.
Move the glue routines for config.old pmax SCSI device probing from
autoconf.c to conf-glue.c.
old-style pmax polled input for cn_getc(). Needed because the
input side of rcons is not initialized in time for GENERIC kernels
to use it to read a root/swap devicename from /dev/console.
Fix an argument glitch between consinit() and pminit().
Change consinit() to use PROM output for remote consoles, because
the serial drivers aren't yet initializable when consinit() is called.

NetBSD/sparc rcons glass-tty console pseudo-device driver, via
the "fb" generic-framebuffer pseudo-device driver.
Individual framebuffer device drivers are now autoconfig glue,
and initialization code for a set of vdac/ramdac-level methods,
called "fbdriver", that's used by all the pmax device drivers.
All the handlers for user-level requests (open/ioctl/read/write/close)
are moved into the fb pseudo-device driver, which uses the
the "fbdriver" methods to work on any given pmax hardware driver.
Framebuffers supported are: sfb cfb mfb xcfb pm.
Move the qvss (pm) -style mmap()ed device interface, kernel tracking
of mouse button/movement events, and placing mouse/keyboard
events in an mmap()ed ring buffer, out of the framebuffer device
drivers and into separate source files. The fb pseudo-device driver
uses the qvss-compatible interface, since that's what the (R5) X
server uses.
Force SCSI driver to register interrupt functions and remove default
handlers.
Bring in a few changes from
Walter Ruetten <walter@ghpc8.ihf.rwth-aachen.de>--more to come later.
Define VIA interrupt functions as returning void, not long.
make sure to use the right buffer (fixed in the same way as pcvt 3.30)
* Maintain keyboard state locally per VT. This makes sense, enables switches
between VTs with different kbd states, and aids Linux VT emulation.
the pmax lance driver that uses the machine-independent am7990.c driver
needs some definitions for it. This is a partial re-merge of NetBSD/alpha's
tc/asic.h back to the pmax, with the addition of symbolic #define's
for registers and bits in registers that are pmax model-specific.
drivers have been fixed to not require "needs-count".
Add back the lines for the "rcons" console driver, even though it's
not merged into the pmax port yet, as conf.h was patched to include
"rcons.h". Adding the device here, but not configuring it (e.g., in
GENERIC) keeps conf.c happy until rcons code is merged.
TURBOChannel cfb has a vertical-retrace interupt that cannot be disabled
in software. 4.4BSD and NetBSD don't supply an interrupt hander and
simply neverenable interrupts from slots with a cfb. This has never
ever worked with a cfb in a 3MIN (Decstation 5000/1xx), where a TURBOChannel
card in slot 0 (or 1 or 2) interrupts at the same IPL as spl0() (or spl1
or spl2), and there's also never been support for selectively enabling or
disabling those interrupts on a 3MIN, in either NetBSD or 4.4BSD.
This revision add an interrupt handler for the cfb, used only on 3MINs,
so that a 3MIN can boot with a cfb as console, and enable/disable of TC
slot interrupts can be debugged. (Serial consoles via ioasic SCCs still
don't quite work, and simply clearing the relevant bits in the R3000 cause
register is apparently over-ridden by a subsequent spl0() somewhere else.)
as it's a driver for a device under a TC IOASIC. The Alpha port also
has its scc driver in tc/scc.c, and the pmax driver scc is nearly the same
as the Alpha.
pmax driver, to be diffable with the NetBSD Alpha driver. Specifically,
the pmax driver now uses register names dev/ic/z8530.h. The driver now
uses new-style config and dynamically-allocated softc structures. The
driver no longer resets the "other" channel on an SCC when changing tty
parameters. The #ifdef'ing away of processing of the output clist for
non-console lines is no longer done. (Non-console serial ttys might even
work now.) Other discrepancies between the pmax and alpha drivers, which I
don't understand yet, are marked by XXXes.
The 4.4bsd pmax console redirection code is still present, protected
by #ifdef TK_NOTYET. Diffs from the Alpha scc driver are now minimal.
Verified to boot on a Decstation 5k/240.
Concomitant changes to code that prints driver/unit name: use dv_xname
and dv_unit, instead of doing pointer arithmetic on elements of the static
softc array.
Remove support for old config. The old-config "driver" structure
is still present, because the pmax non-MI SCSI driver needs it.
Merge some off Per Fogelstrom's changes for the Pica driver,
which uses the machine-independent SCSI code. This is #ifdef'ed
out until the DMA is fixed to work on Decstations, too.
- Don't _ever_ do DMA for less than 512 bytes on the Falcon
- Fix bug in autosense-handling. Now asks for the correct number of bytes.
Now it won't read ghost bytes on the tape anymore.
- Add missing braces as suggested by Matthias Pfaller
- Make it possible to debug requests on a specified number of targets
- Add debug option to show only transaction with error code != 0

Other cleanup (remove cpu040) and enabling IVS A500 support
from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
to match `sd' devices against the PROM's boot path.
Detect DMA "overshoots" when handling odd-sized transfer sizes (e.g., xfers
from/to raw partitions), by using the "Transfer Pad" command when the
transfer count reaches zero.
and MAXINE (Decstation 5k/xx), instead of setting them to NULL.
New-config kernels should work on those machines now.
Rename the definition of the struct cfdriver for the IO ASIC from "asiccd"
to "ioasiccd", as the config-file name changed from "asic" to "ioasic".
the previous version. The machine dependent part contains the configuration
for both the TT and FALCON. The configuration files have been changed to
select SCSI-support for either TT, Falcon or both.
The configuration file for the Atari-Falcon will only get _really_ usefull
when the Falcon video part is finished.
back to the DECstation. Boots on 3MAX and 3MAXPLUS. The bug-fixes
applied to this driver since it forked off the Decstation code also
seem to fix long-standing DMA problems with the Decstation SCSI driver.
All devices except SCSI disks and tapes are found using new config only.
SCSI disks and tapes are configured using a table edited from an ioconf.c
produced by config.old.
Boots multi-user on PMAX, 3MAX and 3MAXPLUS. The old-style "slot hand fill"
functions for those machines, and the old TurboChannel configuration
main loop, have been removed.
Since new-style config runs later in boot than the old pmax turbochannel
probing, we no longer know what devices will be configured when consinit()
is called. Use PROM output until autoconfig is finished.
the Dallas-compatible real-time clock. The missing entry caused the offset
to end up in the "priority" field. New-style config now boots cleanly on a
KN02 (3MAX).
