Different AHCI controllers have a different number of ports, so the core
shouldn't care about the amount of ports available.

This patch makes the number of ports available to the AHCI core runtime
configurable, allowing us to have multiple different AHCI implementations
with different amounts of ports.

The ahci code was missing its soft reset functionality. This wasn't really an

The drive sends a d2h init fis on initialization. Usually, the guest doesn't

Sebastian's patch already did a pretty good job at splitting up ICH-9
AHCI code and the AHCI core. We need some more though. Copyright was missing,
the lspci dump belongs to ICH-9, we don't need the AHCI core to have its
own qdev device duplicate.

So let's split them a bit more in this patch, making things easier to
read an understand.

block/vdi.c:122: error: Using sizeof for array given as function argument returns the size of pointer.
block/vdi.c:128: error: Using sizeof for array given as function argument returns the size of pointer.

Fix both by setting the correct size.

The buggy code is only used when QEMU is build without uuid support.
The bug is not critical, so there is no urgent need to apply it to

Refine the decoding of the Thumb preload and hint space, so we

We also move the tests for this space earlier, so we don't emit

qemu-kvm carries the IOAPIC base address in its v2 vmstate. We only
support the default base address so far, and saving even that in the
device state was rejected.

Add a padding field to be able to read qemu-kvm's old state, but
increase our version to 3, indicating that we are not saving a valid
address. This also gives downstream the chance to change to stop
evaluating the base_address and move to v3 as well.

Starting with SDL version 1.2.14, caps lock and num lock keys
will send a SDL_KEYUP when SDL_DISABLE_LOCK_KEYS=1 is set in
the environment.

The new code sets the environment unconditionally
(it won't harm old versions which do not know it).

The workaround for SDL_KEYUP is only compiled with old SDL versions.

A similar patch without handling of old SDL versions was already
published by Benjamin Drung for Ubuntu.

When the QEMU_CLOCK_HOST clock was added, computation of its
deadline was added to qemu_next_deadline, which is correct but
incomplete.

I noticed this by reading the very convoluted rules whereby
qemu_next_deadline_dyntick is computed, which miss QEMU_CLOCK_HOST
when use_icount is true.  This patch inlines qemu_next_deadline
into qemu_next_deadline_dyntick, and then corrects the logic to skip
only QEMU_CLOCK_VIRTUAL when use_icount is true.
