the NetBSD-1.1 convention. Change the mainbus `struct confargs'
and the "generic" interrupt-establish method, used by devices that
appear on both a kn01 and TC decstations, to match.
Change the macros in autconf.h accordingly.
Add new device-attach struct cfattach le_tc_ca and struct cfdriver le_cd.
Change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd".
Change "mainbuscd" to "mainbus_cd"
update the old-config to new-config glue used with the 4.4bsd/pmax
SCSI drivers to use new device attach declarations and names for
the "oldscsibus", "tz" and "rz" drivers.
- 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.

of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).
works with the revamped machine-independent TC code in sys/dev/tc.
A name change is necessary to avoid a name clash with sys/dev/tc/tc.c,
which also creates a tc.o.
versions work correctly; at some point between then and the immediately
preceding revisions, the "stylistic" changes to one (or both) stdarg.h
and varargs.h broke passing doubles to printf().
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.
code. Substantially the same code tested on a 5k/240. Should work on a
5k/1xx. Not tested on a MAXINE, where the single unit may break the
PROM-channel-number to driver-channel-number mapping.
parameter parameters shadowing locals. Replace vmapbuf() and vunmapbuf()
with the Alpha-port versions, which are cleaner (use round_page(),
trunc_page(), etc.)
* add a new enum decstation_intr_t to trap.c, naming each instrumented
interrupt symbolically, and used to index into intrcnt[]. Change the
model-specific interrupt handlers to use the decstation_intr_t when
updating interrupt counters.
* add instrumentation to the kmin and maxine interrupt handlers.
* fix a bug that counted each hardclock interrupts on the kn02 twice.
The hardcoded mapping from locore names to units is gross; but these
counters will hopefully be useful in identifying interrupt hot-spots
and PPP problems on the 3MIN.
Rename the ioctl asic register and slot macros from ASIC_<xxx> to
IOASIC_<xxx>, to be compatible with the machine-indpendent names in
sys/dev/tc/ioasicvar.h. The pmax code still uses
sys/arch/pmax/pmax/asic.h, as some of the registers and offsets
defined there are not yet defined in sys/dev/tc/ioasicvar.h.
Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'.
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.

the sys/dev/tcvar.h TurboChannel configuration structures. (the initializers
in sys/arch/pmax/tc were already changed; the structure definition wasn't,
which broke autoconfiguration.)
- 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.

page.
be in 1972 or 1973. If the clock is set to the actual time, the PROM
appears to reset the chip date to 1972 at each reboot.
Change the "year offset" from 22 years to 24 years (good till 1997)
until this code is replaced with something that uses the chip as a
seconds-since-beginning-of-year clock (encoded as a date, relative to
1972-01-01 00:00:00).
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.
Kernel-debugger breakpoints in user space, or FP insns that cause
underflow in a delay slot, should now work properly. Single-stepping
of arbitrary user processes, from user level, should be added.
* define PT_GETREGS and PT_SETREGS in pmax/include/ptrace.h
* Flesh out the stubs in pmax/pmax/process_machdep.c to handle
those requests.
* Now that "struct reg" is actually used, remove the bogus
#ifdef LANGUAGE_C around its definition, and redo pmax/include/reg.h
so that the definitions needed by locore.S are in a separate file,
pmax/include/regnum.h.
* update locore.S to match.
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.
Add as-yet-unused speed entries for a 1x SCC clock, up to 200 Kbits.
Remove old top-bit-means-delay code, since nothing seems to need it,
and it apparently partially broke lk-201 initialization anyway.
