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).
turhsturbochannel machines. Lifted wholesale from cgd's Alpha
turbochannel code, with changes that reflect the slightly different
bus topology and `slot' numbering on Decstations.
into a separate function for readability. Rework interrupt initialization,
so interrupts are never enabled until configuration has found and
attached all devices. Call spl0() just before probing the scsi bus,
as the DECstation scsi code can't poll, and hangs if interrupts
are disabled.
Add preliminary support for new config, protected by #ifdef NEWCONF/#endif.
Cosmetic changes to swapconf() and setroot() to reduce distance
from Alpha versions of same.
only print diagnostic messages about interrrupt enabling when DIAGNOSTIC
is defined.
Remove old buggy 4.4BSD turbochannel interrupt kludge for ioasic machines
inside "#if 0"/"#endif" as the NetBSD code has been working fine for months.
redirection of console serial input (keyboard, mouse). Fixes non-redirection of
keyboard to X server on a 5k/240. The Mfb and sfb drivers are similarly broken.
to have the same interface as native readdisklabel(), call it cleanly
from caller of readdisklabel(), and fix bug that left d_npartitions at 1
for ultrix-compat labels. Ultrix labels now actually work.
pmax conf.c references them. A cut-and-paste job from the pmax
rzwrite() and rzread(). tzwrite() and tzread() are utterly untested.
tzwrite() should also check for write-protect, or handle writes to a
write-protected tape gracefully.
consistent with the (default) prepending of underscores to identifiers.
Because this reference is inside an ASM string it's too hairy to
conditionalize to support different toolchains that don't prepend underscores.
(Just don't do profiling with such toolchains.)
