keyboard tricks in SimNOW?

[Myles Watson]

I found a comment in the Serengeti DTS that says it would be nice to look at
an lspci.  I thought "I can do that pretty easily."

I booted a DSL 4.3 CD with the original BIOS and the keyboard doesn't seem
to work.  I tried the paste text command and couldn't get that to work
either.  Each keypress and release is logged correctly by the simulator, but
somehow gets lost.

I booted with a coreboot + LAB kernel, but there are weird key problems
there too.  Even though each key shows up correctly in the shell, only a
random mix of the characters get passed to the shell (most of the times
every other character.) I was able to do an ls /dev/* by typing llss
//ddeevv//**, which passed the command once with Enter, then again with the
next Enter.

Is there a trick to this?  I'm tried it on SimNOW 4.4.1pub 4.4.2pub and
4.4.4pub.

Thanks,
Myles

I don't know the trick but ....

you can always just look at the view config space window :-)

Hmm - I don't know if there is a trick for that or not.  I booted a 
Ubuntu rootfs the other day, and it seemed to work okay, I'll try
to play around and see if I can break it.  I'll send your message
on to the SimNow team to see if they recognize the problem.

I have noticed, however, that the SimNow GUI doesn't take kindly
if I use ctrl-alt-<arrow> to switch workspaces - something about the
control characters seems to confuse it.   Perhaps you are hitting
something similar.

I habitually use ctrl-alt-tab for window switching.  I'll try to control my
fingers and see if that helps.

It seems that DSL doesn't empty the keyboard buffer for some reason.  If I
keep typing long enough it gives this warning:

m_KybKeyBuffer: dropping byte 24 buffer full

Interesting that this only happens after it boots.  I can type at the boot
prompt as long as I type slowly.

Thanks,
Myles

this sounds like interrupts are not happening.
