harcoding defines, and add rpb device type #39 (sii) boot information.
|
|
currently limited to serial console and a single processor working.
All ``on-board'' devices, including the Q-bus adapter, but except for
the frame buffer, are supported. The machine will boot over the network
or from SCSI devices.
Lots of thanks to Al Kossow for www.bitsavers.org, on which I found the
technical documentation allowing me to complete this port (which was
lacking at the time I got that machine...).

temporary until they get merged for good (or split differently).

hardwired this way on KA60...), and compensate in splassert_check() when
serial device interrupts will remain at 0x14 or 0x15.

check frame format...) to a single place. Get rid of duplicated KAxx_FOO
constants.
|
|
hardclock() here, except for KA46 which needs to reset the diagnostic
timer.
This gives us working clock interrupt counters for vmstat -i in the process.

of the console device attachment, and to be able to work on system where there
are more than one dz device of the same type, one of it being the console one.
This also allows a different register layout than the dz@ibus one to be used
for the dz console device.

|
other dz attachments to be able to use them (soon).

transmitter. On machines with glass console for which we do not have
a driver yet, and fall back to serial console, the PROM might not have
enabled it.

early initialization routine (to enable caches, etc) while still running
physical, and does not allocate memory anymore.
(The irony in this is that forthcoming KA60 support actually steals pages
in its init function...)

them, thanks to old ultrix bootblocks lying around.
Also, enable M-Bus clock on the I/O slot IOCSR, this unstucks the cpu
clocks (which really are implemented on the SSC on the I/O module, but
need to be controlled via the cpu's ``internal'' processor registers...)

limited to serial console. This is enough for a 3520 to mopboot and download
a kernel over NFS.

- math.h shouldn't define FLT_EVAL_METHOD, but float.h should (per
C99). remove from math.h, and add proper definitions in float.h

Right now when mi_switch picks up the same proc, we didn't clear the
flag which would mean that every time we service an AST we would attempt
a context switch. For some architectures, amd64 being probably the
most extreme, that meant attempting to context switch for every
trap and interrupt.
Now we clear_resched explicitly after every context switch, even if it
didn't do anything. Which also allows us to remove some more code
in cpu_switchto (not done yet).

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.
|
|
biowait() reads that do *not* come from the buffer cache - we use the
B_RAW flag to identify these at art's suggestion - since it makes sense
and the flag was not being used. this just flags all these buffers with
B_RAW - biodone already ignores returned buffers marked B_RAW.

No functional change.

prompted by krw@
|
|
panic (for you ichc fans out there), disable the wscons console and force a
console device reselection, which ends up in picking a serial console.
This should not happen, but just in case, it's a less rude behaviour.
