      Add KVM support to QEMU · 7ba1e619
      由 aliguori 提交于 
      This patch adds very basic KVM support.  KVM is a kernel module for Linux that
allows userspace programs to make use of hardware virtualization support.  It
current supports x86 hardware virtualization using Intel VT-x or AMD-V.  It
also supports IA64 VT-i, PPC 440, and S390.

This patch only implements the bare minimum support to get a guest booting.  It
has very little impact the rest of QEMU and attempts to integrate nicely with
the rest of QEMU.

Even though this implementation is basic, it is significantly faster than TCG.
Booting and shutting down a Linux guest:

w/TCG:  1:32.36 elapsed  84% CPU

w/KVM:  0:31.14 elapsed  59% CPU

Right now, KVM is disabled by default and must be explicitly enabled with
 -enable-kvm.  We can enable it by default later when we have had better
testing.

      Implement "info chardev" command. (Gerd Hoffmann) · 5ccfae10
      由 aliguori 提交于 
      This patch makes qemu keep track of the character devices in use and
implements a "info chardev" monitor command to print a list.

qemu_chr_open() sticks the devices into a linked list now.  It got a new
argument (label), so there is a name for each device.  It also assigns a
filename to each character device.  By default it just copyes the
filename passed in.  Individual drivers can fill in something else
though.  qemu_chr_open_pty() sets the filename to name of the pseudo tty
allocated.

Output looks like this:

  (qemu) info chardev
  monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait
  serial0: filename=unix:/tmp/run.sh-26827/console,server
  serial1: filename=pty:/dev/pts/5
  parallel0: filename=vc:640x480

      Fix the sendkey hold time calculation (Jan Kiszka). · f227f17d

      Enhance sendkey with key hold time (Jan Kiszka). · c8256f9d
      由 balrog 提交于 
      Current key injection via the monitor basically generates no key hold
time. This is fine for keyboard emulations that have their own queues,
but it causes troubles for those how don't (like the MusicPal - it
simply does not work with injected keys). Moreover, I would like to use
this mechanism to simulate pressed buttons during power-up.

Therefore, this patch enhances the key injection with a configurable
release delay (by default 100 virtual milliseconds).

This feature allows to get rid of the initial sleep() in musicpal_init
because one can now simply start qemu with -S and issue "sendkey m 1000"
and "continue" in the monitor to achieve the desired effect of a pressed
menu button during power-up. So there is no need for a per-musicpal or
even qemu-wide "-hold-button" switch.
