  • Remove ARM NVIC initialization hack ...
    bdb11366 
    The ARMv7-M NVIC device pokes itself into the CPU state.  Now we have a
proper device model we can have the CPU/SoC code do this.

  • fix gdbstub support for multiple threads in usermode, v3 ...
    1e9fa730 
    When debugging multi-threaded programs, QEMU's gdb stub would report the
correct number of threads (the qfThreadInfo and qsThreadInfo packets).
However, the stub was unable to actually switch between threads (the T
packet), since it would report every thread except the first as being
dead.  Furthermore, the stub relied upon cpu_index as a reliable means
of assigning IDs to the threads.  This was a bad idea; if you have this
sequence of events:

initial thread created
new thread #1
new thread #2
thread #1 exits
new thread #3

thread #3 will have the same cpu_index as thread #1, which would confuse
GDB.  (This problem is partly due to the remote protocol not having a
good way to send thread creation/destruction events.)

We fix this by using the host thread ID for the identifier passed to GDB
when debugging a multi-threaded userspace program.  The thread ID might
wrap, but the same sort of problems with wrapping thread IDs would come
up with debugging programs natively, so this doesn't represent a
problem.

  • User Networking: Enable removal of redirections ...
    c1261d8d 
    Using the new host_net_redir command you can easily create redirections
on the fly while your VM is running.

While that's great, it's missing the removal of redirections, in case you
want to have a port closed again at a later point in time.

This patch adds support for removal of redirections.

  • Allow monitor interaction when using migrate -exec ...
    8a43b1ea 
    All,
     I've recently been playing around with migration via exec.  Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened.  This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time.  This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.

(note: developed/tested with qemu-kvm, but applies perfectly fine to qemu)

  • fully split aio_pool from BlockDriver ...
    c16b5a2c 
    Now that we have a separate aio pool structure we can remove those
aio pool details from BlockDriver.

Every driver supporting AIO now needs to declare a static AIOPool
with the aiocb size and the cancellation method.  This cleans up the
current code considerably and will make it cleaner and more obvious
to support two different aio implementations behind a single
BlockDriver.

  • qcow: add qcow_aio_setup helper ...
    ad53089b 
    [this one is required for [PATCH] fully split aio_pool from BlockDriver,
 sorry for not sending it out earlier]

Add a qcow_aio_setup helper to qcow to shared common code between
the aio_readv and aio_writev methods.  Based on the function with
the same name in qcow2.

  • raw-posix: fix hdev_create ...
    4099df58 
    We do need hdev_create unconditionally on all platforms so that qemu-img
create support for host device works on all platforms.

Also relax the check to allow character devices in addition to block
devices.  On many Unix platforms block devices have buffered block
nodes and unbuffered character device nodes, and on FreeBSD the block
nodes don't even exist anymore.  Also on Linux we do support the
/dev/sgN scsi passthrough devices through the host device driver,
and probably the old-style /dev/raw/rawN raw devices although I haven't
tested that.
