This patch upgrades the emulated UART to 16550A, the code comes from
xen-unstable. The main improvement was introduced with the following patch and
subsequent email thread:

http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00129.html

The changes compared to previous version are:

- change clock_gettime to qemu_get_clock

- no token bucket anymore;

- fixed a small bug handling IRQs; this was the problem that prevented
kgdb to work over the serial (thanks to Jason Wessel for the help
spotting and reproducing this bug).

- many many style fixes;

- savevm version number increased;

- not including termios.h and sys/ioctl.h anymore, declaring static
constants in qemu-char.h instead;

It is not enough to check for pkg-config gnutls.  You may be using a
cross-compiler and have gnutls available on the host but not for the target.
This patch changes the detection to try and build an application using gnutls
and whatever compiler is available.

e1000_receive() has code to raise a receive overflow interrupt when the receive
buffer head and tail match. However, with the present implementation of
e1000_can_receive(), this code is unreachable -- and etherboot breaks as a
result.

Compilation of QEMU is currently broken on Solaris due to nbd's use of _IO and
due to network libraries not being linked into qemu-img.

The attached patch adds the appropriate libraries (copied from Makefile.target)
and includes an additional Sun-specific header for _IO.

With these fixes it compiles okay, on OpenSolaris snv_93 (amd64).

This patch allows to display the "Password:" prompt if we use encrypted
disk with "-nographic" option.

It also modifies management of "-nographic" to not override user's
choices for "-serial", "-parallel" and "-monitor".

When qemu has to ask a password with "-nographic" with a multiplexed
serial interface, it forces the focus to the monitor and restore
original focus after.

to compile [cpu-]exec.c with gcc3 and -O, also the function is much

This patch moves the pty char device imlementation away from the generic
filehandle code.  It tries to detect as good as possible whenever there
is someone connected to the slave pty device and only send data down the
road in case someone is listening.  Unfortunaly we have to poll via
timer once in a while to check the status because we have to use read()
on the master pty to figure the status (returns -EIO when unconnected).

Poll intervall for an idle guest is one second, when the guest sends
data to the virtual device linked to the pty we check more frequently.

The point for all of this is to avoid qemu blocking and not responding
any more.  Writing to the master pty handle succeeds even when nobody is
connected to (and reading from) to the slave end of the pty.  The kernel
just bufferes the writes.  And as soon as the kernel buffer is full the
write() call blocks forever ...
