Hi,
are there any plans to extend the serial port emulation in QEMU?
Currently, it emulates a 16450 hardware, but most modern boards
are 16550A compatible. The 16550A hardware gives better performance
for serial applications (e.g. serial protocols), and I expect
that it might do this in an emulation environment, too.
I found a port for 16550A emulation in an earlier contribution
(http://lists.gnu.org/archive/html/qemu-devel/2006-02/msg00004.html),
but it obviously did not get much attention...
When I tried this 16550A patch, it worked but surprisingly slowed
down the serial output.
Regards
Stefan
