As we make upper bits in IO and prefetcheable memory
registers writeable, we should declare support
for 64 bit prefetcheable memory and 32 bit io
in the bridge.
This changes the default for apb, dec, but I'm guessing
they got the defaults wrong by accident.
Alternatively, we could let bridges declare lack of
64 bit support and make the upper bits read-only zero.
With this applied, we can drop these bits
from express code.

pci_regs.h specifies many registers by mask +
shifted register values.
There's always some duplication when using such:
for example to override device type, we would need:
pci_word_test_and_clear_mask(cap + PCI_EXP_FLAGS,
PCI_EXP_FLAGS_TYPE);
pci_word_test_and_set_mask(cap + PCI_EXP_FLAGS,
PCI_EXP_TYPE_ENDPOINT << (ffs(PCI_EXP_FLAGS_TYPE) - 1));
Getting such registers also uses some duplication:
word = pci_get_word(cap + PCI_EXP_FLAGS) & PCI_EXP_FLAGS_TYPE;
if ((word >> ffs((PCI_EXP_FLAGS_TYPE) - 1)) == PCI_EXP_TYPE_ENDPOINT)
Add API to access such registers in one line:
pci_set_word_by_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE,
PCI_EXP_TYPE_ENDPOINT)
and
word = pci_get_word_by_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE)
if (word == PCI_EXP_TYPE_ENDPOINT)

Flash can be enabled by calling pc_system_firmware_init

If system_flash_enabled is zero, then the older qemu
rom creation method will be used.
If flash is enabled and a pflash image is found, then
it is used for the system firmware image.
If flash is enabled and a pflash image is not initially
found, then a read-only pflash device is created using
the -bios filename.
KVM cannot execute from a pflash region currently.
Therefore, when KVM is enabled, the old rom based
initialization method is used.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Hex properties are an obstacle to removal of old qdev string parsing, but
even here we can lay down the foundations for future simplification. In
general, they are rarely used and their printed form is more interesting
than the parsing. For example you'd usually set isa-serial.index
instead of isa-serial.iobase. And luckily our main client, libvirt
only cares about few of these, and always sets them with a 0x prefix.
So the series stops accepting bare hexadecimal numbers, preparing for
making legacy properties read-only in 1.3 or so. The read side will
stay as long as "info qtree" is with us.

With the acceptance of some new APIs to libspice-server.so it
is possible to add support for SPICE to the 'add_client'
monitor command, bringing parity with VNC. Since SPICE can
use TLS or plain connections, the command also gains a new
'tls' parameter to specify whether TLS should be attempted
on the injected client sockets.
This new feature is only enabled if building against a
libspice-server >= 0.10.1

'skipauth' parameter
* monitor.c: Wire up SPICE for 'add_client' command

This patch fixes the local qxl renderer to not kick spice-server
in case the vm is stopped. First it is largely pointless because
we ask spice-server to process all not-yet processed commands when
the vm is stopped, so there isn't much do do anyway. Second we
avoid triggering an assert in spice-server.
The patch makes sure we still honor redraw requests, even if we don't
ask spice-server for updates. This is needed to handle displaysurface
changes with a stopped vm correctly.
With this patch applied it is possible to take screen shots (via
screendump monitor command) from a qxl gpu even in case the guest
is stopped.

When the HPET enters legacy mode, the IRQ output of the PIT is
suppressed and replaced by the HPET timer 0. But the current code to
emulate this was broken in many ways. It reset the PIT state after
re-enabling, it worked against a stale static PIT structure, and it did
not properly saved/restored the IRQ output mask in the PIT vmstate.
This patch solves the PIT IRQ control in a different way. On x86, it
both redirects the PIT IRQ to the HPET, just like the RTC. But it also
keeps the control line from the HPET to the PIT. This allows to disable
the PIT QEMU timer when it is not needed. The PIT's view on the control
line state is now saved in the same format that qemu-kvm is already
using.
Note that, in contrast to the suppressed RTC IRQ line, we do not need to
save/restore the PIT line state in the HPET. As we trigger a PIT IRQ
update via the control line, the line state is reconstructed on mode
switch.

In legacy mode, the HPET suppresses the RTC interrupt delivery via IRQ
8 but keeps track of the RTC output level and applies it when legacy
mode is turned off again. This value has to be preserved across save/
restore as it cannot be reconstructed otherwise.
To document that a raised rtc_irq_level won't survive a vmload without
a hpet/rtc_irq_level subsection, add an explicit clearing to the reset
handler.
