Markus Armbruster 719a30776b Purge uses of banned g_assert_FOO()
We banned use of certain g_assert_FOO() functions outside tests, and
made checkpatch.pl flag them (commit 6e9389563e).  We neglected to
purge existing uses.  Do that now.

Markus Armbruster 717ea844a7 Revert "Makefile: add target to print generated files"
This reverts commit 9578f8cc3e.

The patch snuck in by accident without having been posted to
qemu-devel.  It's entirely redundant: existing target print-% already
serves the purpose.

Here's another batch of ppc patches towards the 3.0 release.  There's
 a fair bit here, because I've been working through my mail backlog
 after a holiday.  There's not much of a central theme, amongst other
 things we have:
     * ppc440 / sam460ex improvements
     * logging and error cleanups
     * 40p (PReP) bugfixes
     * Macintosh fixes and cleanups
     * Add emulation of the new POWER9 store-forwarding barrier
       instruction variant
     * Hotplug cleanups

Marc-André Lureau 265b578c58 object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalence
A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().

add_link() doesn't add a reference to the target object, while
set_link() does.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.

Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

David Gibson 30f79dc13f spapr_pci: Remove unhelpful pagesize warning
By default, the IOMMU model built into the spapr virtual PCI host bridge
supports 4kiB and 64kiB IOMMU page sizes.  However this can be overridden
which may be desirable to allow larger IOMMU page sizes when running a
guest with hugepage backing and passthrough devices.  For that reason a
warning was printed when the device wasn't configured to allow the pagesize
with which guest RAM is backed.

Experience has proven, however, that this message is more confusing than
useful.  Worse it sometimes makes little sense when the host-available page
sizes don't match those available on the guest, which can happen with
a POWER8 guest running on a POWER9 KVM host.

Long term we do want better handling to allow large IOMMU page sizes to be
used, but for now this parameter and warning don't really accomplish it.
So, remove the message, pending a better solution.

Cédric Le Goater c8fd8373e4 target/ppc: extend eieio for POWER9
POWER9 introduced a new variant of the eieio instruction using bit 6
as a hint to tell the CPU it is a store-forwarding barrier.

The usage of this eieio extension was recently added in Linux 4.17
which activated the "support for a store forwarding barrier at kernel
entry/exit".

Unfortunately, it is not possible to insert this new eieio instruction
without considerable change in ppc_tr_translate_insn(). So instead we
loosen the QEMU eieio instruction mask and modify the gen_eieio()
helper to test for bit6. On non-POWER9 CPUs, the bit6 is just ignored
but a warning is emitted as this is not an instruction software should
be using.

Mark Cave-Ayland 3431bdf5a3 mos6522: convert VMSTATE_TIMER_PTR_TEST to VMSTATE_TIMER_PTR
The timers are configured in the mos6522 init function and therefore will
always exist, so the function can never return false.

Peter also pointed out that this is the only remaining user of
VMSTATE_TIMER_PTR_TEST in the codebase, so we might as well just convert it
over to VMSTATE_TIMER_PTR and remove mos6522_timer_exist() as it is no
longer required.

Mark Cave-Ayland d638fd5c96 mos6522: move timer frequency initialisation to mos6522_reset
The 6522 VIA timer frequency cannot be set by altering registers within the
device itself and hence it is a fixed property of the machine.

Move the initialisation of the timer frequency to the mos6522 reset function
and ensure that any subclasses always call the parent reset function so that
it isn't required to store the timer frequency within vmstate_mos6522_timer
itself.

By moving the frequency initialisation to the device reset function then we
find that the realize function for both mos6522 and mos6522_cuda becomes
obsolete and can simply be removed.

Mark Cave-Ayland 2e3e5c7e92 cuda: embed mos6522_cuda device directly rather than using QOM object link
Examining the migration stream it can be seen that the mos6522 device state is
being stored separately rather than as part of the CUDA device which is
incorrect (and likely to cause issues if another mos6522 device is added to
the machine).

Resolve this by embedding the mos6522_cuda device directly within the CUDA
device rather than using a QOM object link to reference the device separately.

Note that we also bump the version in vmstate_cuda to reflect this change: this
isn't particularly important for the moment as the Mac machine migration isn't
100% reliable due to issues migrating the timebase under TCG.

Cédric Le Goater efe2add7cb spapr/vio: deprecate the "irq" property
VIO devices have an "irq" property that can be used by the sPAPR IRQ
allocator as an IRQ number hint. But it is not set in QEMU nor in
libvirt. It brings unnecessary complexity to the underlying layers
managing the IRQ number space and it is in full opposition with the
new static IRQ allocator we want to introduce in sPAPR.

Let's deprecate it to simplify the spapr_irq_alloc routine in the
future.

Joel Stanley 6b37554458 target/ppc: Allow privileged access to SPR_PCR
The powerpc Linux kernel[1] and skiboot firmware[2] recently gained changes
that cause the Processor Compatibility Register (PCR) SPR to be cleared.

These changes cause Linux to fail to boot on the Qemu powernv machine
with an error:

 Trying to write privileged spr 338 (0x152) at 0000000030017f0c

With this patch Qemu makes this register available as a hypervisor
privileged register.

Note that bits set in this register disable features of the processor.
Currently the only register state that is supported is when the register
is zeroed (enable all features). This is sufficient for guests to
once again boot.
