QEMU only emulates a serial interface without FIFO,
so Linux gets one interrupt per character sent or received.
And the emulation does not emulate the original speed
of the serial interface, but runs at fastest speed possible.
I get this log message every time when a program writes
more than a few
In the mips emulator I often see "serial8250: too much work for irq4",
particularity when running vi etc. Is that to be expected, and known about?
If so, please ignore this ;-), if not, I thought you may like to know.
