I believe so.
Most Solaris folk aren't really accustomed to just rebooting their
machines.
So I guess I fit in? I don't even like rebooting NT 4. ;)
Fear. ;)

First of all, Cory...have you tried using Sun's compiler? It kicks the snot out

I would suggest that this would be a good idea.
I have an old SparcStation which I fire up once every few years to test simh on a Big Endian platform. It has a Linux disk and a Solaris disk (I don't recall the version). I do not have a sun C compiler. The last time I fired it up (more than a year ago) the basic testing worked out fine but I noticed that some things were so slow it was practically unusable. I isolated some slow behavior down to an operation which walked across a 64MB chunk of VAX memory one byte at a time. The 64MB array is stored in a single malloc'ed area. This walk across the 64MB took some 20 seconds, while the same operation on my Windows desktop takes far less than any time I could measure on my watch. My theory was that it was spending all of its time in the alignment trap handler, but I didn't have enough knowledge to dig into the details.
The test case is demonstrated by the following commands:
$ BIN/vax
MicroVAX 3900 simulator V4.0-0 Beta
sim> set cpu 64m
sim> save somefile
The save operation writes the current simulator state to a file.
It sounds to me like you need a fast SPARC, or access to one.
I can give you an account on dev.neurotica.com, which is an
UltraSPARC-T1-based machine running Solaris 10 with Sun's C compiler
installed. Several people are using it for free software projects;
that's its purpose in life.
Let me know if you're interested.

I have no idea. You guys have dug up this info....

machines.

I suggest that you make the change to /etc/system now so you don't forget when you go to shutdown to install the NICs or you'll end up with multiple reboots at that time....
Then again, if your system has trouble rebooting after installing the NICs you won't know if it has to do with the newly added hardware or the change to the OS configuration file....
I like to test one change at a time.

Is it okay if I wait a day or so to add those? It requires a reboot
to do that and i'm planning on taking the system down for maintenance
in a couple days when some NICs get here. I like not having to
reboot multiple times. ;)
Your NICs are on the way; I'd expect you should have them tomorrow or
Friday.
That's what I estimated as well. Thanks.

Ahhh.
"Solaris timing uses a real-time clock that can generate
interrupts at a resolution bound by the processor speed. For
scheduling purposes, it fires every 10 milliseconds. As in Linux,
this is a clock "tick." Note that 2.6 Linux uses a
1000-tick/second clock, as opposed to the 100-tick/second clock
used by Solaris and by previous versions of Linux. User-level
programs on Solaris can program the real
time clock to fire at nanosecond granularity, rounded up by processor
time-- much finer than the clock tick granularity of ten or one milliseconds.
However, the program interface to use the high-resolution timers
is not visible in the DDI/DKI. See clock_settime(3rt) for
user-level details andusr/src/uts/common/os/cyclic.c for details
on high-resolution
timing in Solaris.
Also note that in Solaris, you can change the value of hz or clock
ticks/second by setting hires_tick to 1 and hires_hz to the
desired time in the /etc/system file. The default is
1000 ticks per second. Here's an example:
set hires_tick=1
set hires_hz=10000 <~--- 10000 ticks per second"
Looks like Solaris can set it in user mode, too.
This 'documented' tick rate would seem to meet simh's requirements
without any adjustments.
Does the current simh code work? If not, what does it think the
tick size
is?
I will tell you once I work around ld: fatal: auxiliary filter
option (-f, --auxiliary) is only available when building a shared
object
ld: fatal: flags processing errors

Same result as Brian. 11ms instead of 10.
OK. So, now it is time to try and adjust the system clock tick.
What are the current values in /etc/system?
What happens if you change /etc/system to have:
set hires_tick=1
set hires_hz=1000
Reboot and try the simh vax again....

Sure, but what are the current values in /etc/system?
The keys mentioned above are not currently in /etc/system.
Meanwhile, I've changed the makefile so that it should work on your platform without any modification. Please test the latest from github.
Builds fine now. Thank you.
