Rework pmax kernel config:
...
* ibus (virtual bus for baseboard direct-attach deviecs)
* 5100 support, using ibus
* rename "clock" to mcclock for future support of Qbus machiens
* use sys/dev/dec mcclock_pad32 machinery for pmax mcclock
* reworked TC config code.

Configure mips_mclock if "clock|mccclock".
...
All(?) ARC boxes use mcclock, but QBus decstations use the same
time-of-year clock architecturally mandated for VAXes.

9caaf18836
Rework pmax turbochannel config, as suggested by Jason Thorpe.
...
Also make TC framebuffer-console search table-driven.
Does not yet include "tcasic" layer; there's no such hardware on DECstations
and nothing for a tcasic layer to do.

oops, diffs to use dev/dec/mcclock_pad32 were in a different tree. Fix.

c84f4e94d9
Copy alpha/tc/mcclock_ioasic.c (duplicated in pmax/tc/mcclock_ioasic.c)
...
into sys/dev/dec and split into a clockfns layer and a "middle" layer
for other DEC systems which use mcclocks with each onchip byte
register padded out to a 32-bit word.
Clone alpha/alpha/mcclock (also duplicated in pmax port) into
sys/dev/dec, and ifdef for default clockrates on pmax and alpha.
Use new machinery on pmax for ibus,ioasic attached mcclocks.

the last possible hooks having been removed from rpc_machdep.c

Change definitions of MCOUNT_ENTER and MCOUNT_EXIT to block interrupts

via the CPSR rather than via splhigh() due to the overheads involved
in using splhigh()/splx(). (From Chris Demetriou).

Overhaulled cpu_reboot(). Junked all the boot action garbage and just use
...
howto to dictate what operations to perform.
Removed support for calling the deprecated kshell stuff.
Cleaned up a few bits of dead code and renamed rpc_sa110_kickstart() to
rpc_sa110_cc_setup().

53c671e26c
Add locore assembler functions to read mips3 cycle counter, and
...
read and write compare register (controls cycle-driven periodic interrupt).
Use cycle counter for microsecond time on mips3, but for now only on
3min motherboards (5000/150). the MAXINE baseboard microsecond
counter is more stable and I don't ave no 5000/260 to test.
XXX clkread() is a mess, it should be rewritten.
XXX should add nanotime() to give inkernel nanosecond resolution,
and then microtime() reworked to use nanotime().
1998-04-19 01:48:34 +00:00

Decsystem 5100 (aka mipsmate aka kn230) support:
...
* 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.
