Hi everyone,
I've written a couple of questions regarding the serial device in KVM.
After slightly more investigation I think I have found what's going
awry. Correct me if I'm wrong, but I believe that KVM generates an
interrupt for every single character it sends through the serial port.
This throws CPU usage through the roof and I suspect this means that the
timers aren't being handled correctly and it failed on a string of 0's
for me due to the timing slips. GNU/Linux and Windows don't have
anywhere near the processor usage for their serial ports. Now, I know
nothing of serial programming and don't have any time to investigate it
too heavily just now, but I have pulled down the source and had a look
through that, but it looks to be doing the right thing (I suppose?). I
was mainly wondering how GNU/Linux and windows handle serial interrupts
or if some of the serial character events could be buffered, rather than
overload the processor? I guess this is a low priority for you, but any
help would be greatly appreciated (And when I have some more time, I
will spend some of it helping to develop KVM! Quid pro quo, Clarice...)
Thanks,
Michael
