      serial: fix lost character after sysrq · 40ff1624
      由 Jason Wessel 提交于 
      After creating an automated regression test to test the sysrq
responses while running a linux image in qemu, I found that the
simulated uart was eating the character right after the sysrq about
75% of the time.

The problem is that the qemu sets the LSR_DR (data ready) bit on a
serial break.  The automated tests can send a break and the sysrq
character quickly enough that the qemu serial fifo has a real
character available. When there is valid character in the fifo, it
gets consumed by the serial driver in the guest OS.

The real hardware also appears to set the LSR_DR but always appears to
have a null byte in this condition.  This patch changes the qemu
behavior to match the tested characteristics of a real 16550 chip.

      usb-serial: implement break event. · 7e57f049
      由 Jason Wessel 提交于 
      Implement the serial break via usb serial.

The second data byte in ftdi status packet contains the break status.
The values were already defined in usb-serial.c so it was a matter of
making use of the event_trigger to form a urb to send over to the host
controller with the serial break status set.

This was tested against a linux development image which enables sysrq
via a serial break on the ftdi usb console.

      Introduce reset notifier order · 8217606e
      由 Jan Kiszka 提交于 
      Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

      kvm: Fix framebuffer dirty log sync · 93102fd6
      由 Jan Kiszka 提交于 
      kvm_physical_sync_dirty_bitmap() takes the end address as second
argument, not the region size. Moverover, the kvm API should not be used
directly here, but cpu_physical_sync_dirty_bitmap().

      Introduce is_default field for QEMUMachine · 0c257437
      由 Anthony Liguori 提交于 
      f80f9ec9 changed the order that machines are registered which had the effect of
changing the default machine.  This changeset introduces a new is_default field
so that machine types can declare that they are the default for an architecture.

      Refactor how display drivers are selected · 993fbfdb
      由 Anthony Liguori 提交于 
      My previous commit, f92f8afe,  broke -vnc (spotted by Glauber Costa).  This
is because it's necessary to tell when the no special display parameters have
been passed and default to SDL or VNC appropriately.

This refactors the display selection logic to be less complicated which has
the effect of fixing the regression mentioned above.
