  • ETRAX: Removed unused struct entry and fixed Windows build. ...
    3cb5a223 
    "struct timeval last" caused a compilation error with mingw32
(missing header for struct timeval).

It is unused, so it was possible to remove it.

  • Add common BusState ...
    02e2da45 
    Implement and use a common device bus state.  The main side-effect is
that creating a bus and attaching it to a parent device are no longer
separate operations.  For legacy code we allow a NULL parent, but that
should go away eventually.

Also tweak creation code to veriry theat a device in on the right bus.

    Bit 0 is the enable bit, which we not only don't want to set, but
it will stick and make us think it's an I/O port resource.

  • Add HTTP protocol using curl v6 ...
    769ce76d 
    Currently Qemu can read from posix I/O and NBD. This patch adds a
third protocol to the game: HTTP.

In certain situations it can be useful to access HTTP data directly,
for example if you want to try out an http provided OS image, but
don't know if you want to download it yet.

Using this patch you can now try it on on the fly. Just use it like:

qemu -cdrom http://host/path/my.iso

  • USB serial device support ...
    d55ebf55 
    Add in a workaround to allow the usb serial devices to work with the
usb pass through mechanism.  The ioctl() to request an alternate
interface will always return < 0 for a usb-serial device based on the
kernel driver.  This means there is no alternate interface end point.

This was fully tested with a pl2303 usb serial device.

  • serial: fix lost character after sysrq ...
    40ff1624 
    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 
    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.

    0928a95f 
    In case a client restarts a DHCP recovery without releasing its old
address, reassign the same address to prevent consuming free addresses
and moving away from the standard client address.

  • kvm: x86: Save/restore KVM-specific CPU states ...
    f8d926e9 
    Save and restore all so far neglected KVM-specific CPU states. Handling
the TSC stabilizes migration in KVM mode. The interrupt_bitmap and
mp_state are currently unused, but will become relevant for in-kernel
irqchip support. By including proper saving/restoring already, we avoid
having to increment CPU_SAVE_VERSION later on once again.

v2:
 - initialize mp_state runnable (for the boot CPU)

  • Introduce reset notifier order ...
    8217606e 
    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_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().

  • kvm: Add missing bits to support live migration ...
    b0a46a33 
    This patch adds the missing hooks to allow live migration in KVM mode.
It adds proper synchronization before/after saving/restoring the VCPU
states (note: PPC is untested), hooks into
cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging
at KVM level, and synchronizes that drity log into QEMU's view before
running ram_live_save().
