vnc_update_client currently scans the dirty bitmap of each client
bitwise which is a very costly operation if only few bits are dirty.
vnc_refresh_server_surface does almost the same.
this patch optimizes both by utilizing the heavily optimized
function find_next_bit to find the offset of the next dirty
bit in the dirty bitmaps.

Few bits dirty - vnc_update_client_new: 0.08 secs

The case for all bits dirty is still rather slow, this
is due to the implementation of find_and_clear_dirty_height.

Hi,

When I use RealVNC viewer client (http://www.realvnc.com/) to connect vnc server,
the client disconnect suddenly, and I click reconnect button immediately, then the Qemu crashed.

In the function vnc_worker_thread_loop, will call vnc_async_encoding_start
to set the local vs->output buffer by global queue's buffer. Then send rectangles to
the vnc client call function vnc_send_framebuffer_update. Finally, Under normal circumstances,
call vnc_async_encoding_end to set the global queue'buffer by the local vs->output conversely.

When the vnc client disconnect, the job->vs->csock will be set to -1. And the current prcoess
logic will goto disconnected partion without call function vnc_async_encoding_end.
But, the function vnc_send_framebuffer_update will call buffer_reserve, which
maybe call g_realloc reset the local vs's buffer, meaning the global queue's buffer is modified also.
If anyone use the original global queue's buffer memory will cause corruption and then crash qemu.

This patch assure the function vnc_async_encoding_end being called
even though the vnc client disconnect suddenly.

tight_detect_smooth_image() first promotes it to int, then compares
with -1.  Always unequal, so we always execute the lossy code.  Reads

Signed-off-by: NMark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

Both QEMU and KVM have already accumulated a significant number of
optimizations based on the hard-coded assumption that ioapic polarity
will always use the ActiveHigh convention, where the logical and
physical states of level-triggered irq lines always match (i.e.,
active(asserted) == high == 1, inactive == low == 0). QEMU guests
are expected to follow directions given via ACPI and configure the
ioapic with polarity 0 (ActiveHigh). However, even when misbehaving
guests (e.g. OS X <= 10.9) set the ioapic polarity to 1 (ActiveLow),
QEMU will still use the ActiveHigh signaling convention when
interfacing with the emulated ioapic.

This patch modifies the emulated ioapic to completely ignore polarity
as set by the guest OS, enabling misbehaving guests to work alongside
those which comply with the ActiveHigh polarity specified by QEMU's
ACPI tables.

Assume that in this mode, no read access is ever done, as they shouldn't

Windows XP shows COM2 port as non functional in
"Device Manager" although no COM2 port backing device
is present in QEMU.

This regression is really due to
3bb28b72?
    memory: Provide separate handling of unassigned io ports accesses

That is caused by the fact that QEMU reports to
OSPM that device is present by setting 5th bit in
PII4XPM.pci_conf[0x67] register when COM2 doesn't
exist.

It happens due to memory_region_present(io_as, 0x2f8)
returning false positive since 0x2f8 address eventually
translates into catchall io_as address space.

Fix memory_region_present(parent, addr) by returning
true only if addr maps into a MemoryRegion within
parent (excluding parent itself), to match its
doc comment.

While at it fix copy/paste error in
memory_region_present() doc comment.

Note: this is a temporary hack: we really need better handling for
unassigned regions, we should avoid fallback regions since they are bad
for performance (breaking radix tree assumption that the data structure
is sparsely populated); for memory we need to fix this to implement PCI
master abort properly, anyway.

As reported in

Mac OSX actually requires describing all occupied slots

As a result: before

hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.

To fix, append description for all occupied non hotpluggable PCI slots.

One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.
