target-alpha: Fix ret instruction

Hopefully pine doesn't corrupt this patch, I've had problems recently.

For an alpha "ret" instruction, of the type
     ret $26

The return was being ignored.  This is because in translate.c
register $26 (the return address) was being over-written with the current
PC before it could be jumped to.  Thus the ret was ignored.

This patch just re-orders things so the return address is processed before
it is over-written with the current PC.

Fix windows build after init_host_timer changes.

host_alarm_timer fires in a separate thread.  The windows build current
uses SetEvent() and WaitEvent() to then notify the main thread.  This is
functionally equivalent to what we're doing in Unix with pipe().  So let's
just #ifdef the pipe() code on Windows since it doesn't build there anyway.

Fix alarm_timer race with select - v3 (Jan Kiszka)

Changing the default IO timeout to 5 s (#5578) made a race visible
between the alarm_timer and select() in main_loop_wait(): If the timer
fired before select was able to block, the full select() timeout could
have been applied instead of returning immediately. Since #5578, this
causes heavy problems to the Musicpal board emulation with stalls up to
5 s, but also with some older Linux guest kernels.

The following patch introduces a pipe that is written to by
host_alarm_handler and select()'ed in main_loop_wait(). This avoids
prevents that select() blocks though a timer has fired and waits for
processing.

Add KVM support to QEMU

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.

Add safety net against potential infinite loop

cpu_interrupt might be called while translating the TB, but before it
is linked into a potentially infinite loop and becomes env->current_tb.

Currently this can (and does) cause huge problems only when using
dyntick clock, with other (periodic) clocks host_alarm_handler will
eventually be executed resulting in a call to cpu_interrupt which will
reset the recursion of running TB and the damage is "only" latency.

Implement "info chardev" command. (Gerd Hoffmann)

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

In short all 'memset;goto redo' places must be fixed to use the bh and
not to call the callback in the context of bdrv_aio_read or the

Make DMA bottom-half driven (v2)

The current DMA routines are driven by a call in main_loop_wait() after every
select.

This patch converts the DMA code to be driven by a constantly rescheduled
bottom half.  The advantage of using a scheduled bottom half is that we can
stop scheduling the bottom half when there no DMA channels are runnable.  This
means we can potentially detect this case and sleep longer in the main loop.

The only two architectures implementing DMA_run() are cris and i386.  For cris,
I converted it to a simple repeating bottom half.  I've only compile tested
this as cris does not seem to work on a 64-bit host.  It should be functionally
identical to the previous implementation so I expect it to work.

For x86, I've made sure to only fire the DMA bottom half if there is a DMA
channel that is runnable.  The effect of this is that unless you're using sb16
or a floppy disk, the DMA bottom half never fires.

You probably should test this malc.  My own benchmarks actually show slight
improvement by it's possible the change in timing could affect your demos.

Since v1, I've changed the code to use a BH instead of a timer.  cris at least
seems to depend on faster than 10ms polling.

Make bottom halves more robust

Bottom halves are supposed to not complete until the next iteration of the main
loop.  This is very important to ensure that guests can not cause stack
overflows in the block driver code.  Right now, if you attempt to schedule a
bottom half within a bottom half callback, you will enter an infinite loop.

This patch uses the same logic that we use for the IOHandler loop to make the
bottom half processing robust in list manipulation while in a callback.

This patch also introduces idle scheduling for bottom halves.  qemu_bh_poll()
returns an indication of whether any bottom halves were successfully executed.
qemu_aio_wait() uses this to immediately return if a bottom half was executed
instead of waiting for a completion notification.

qemu_bh_schedule_idle() works around this by not reporting the callback has
run in the qemu_bh_poll loop.  qemu_aio_wait() probably needs some refactoring
but that would require a larger code audit.  idle scheduling seems like a good
compromise.
