ef28b98d58 spapr_pci: add PHB unrealize
To support PHB hotplug we need to clean up lingering references,
memory, child properties, etc. prior to the PHB object being
finalized. Generally this will be called as a result of calling
object_unparent() on the PHB object, which in turn would normally
be called as the result of an unplug() operation.

When the PHB is finalized, child objects will be unparented in
turn, and finalized if the PHB was the only reference holder. so
we don't bother to explicitly unparent child objects of the PHB,
with the notable exception of DRCs. This is needed to avoid a QEMU
crash when unplugging a PHB and resetting the machine before the
guest could handle the event. The DRCs are removed from the QOM tree
by  pci_unregister_root_bus() and we must make sure we're not leaving
stale aliases under the global /dr-connector path.

The formula that gives the number of DMA windows is moved to an
inline function in the hw/pci-host/spapr.h header because it
will have other users.

The unrealize function is able to cope with partially realized PHBs.
It is hence used to implement proper rollback on the realize error
path.

6cead90c5c xics: Write source state to KVM at claim time
The pseries machine only uses LSIs to support legacy PCI devices. Every
PHB claims 4 LSIs at realize time. When using in-kernel XICS (or upcoming
in-kernel XIVE), QEMU synchronizes the state of all irqs, including these
LSIs, later on at machine reset.

In order to support PHB hotplug, we need a way to tell KVM about the LSIs
that doesn't require a machine reset. An easy way to do that is to always
inform KVM when an interrupt is claimed, which really isn't a performance
path.

d9c95c71ac spapr_drc: Allow FDT fragment to be added later
The current logic is to provide the FDT fragment when attaching a device
to a DRC. This works perfectly fine for our current hotplug support, but
soon we will add support for PHB hotplug which has some constraints, that
CPU, PCI and LMB devices don't seem to have.

The first constraint is that the "ibm,dma-window" property of the PHB
node requires the IOMMU to be configured, ie, spapr_tce_table_enable()
has been called, which happens during PHB reset. It is okay in the case
of hotplug since the device is reset before the hotplug handler is
called. On the contrary with coldplug, the hotplug handler is called
first and device is only reset during the initial system reset. Trying
to create the FDT fragment on the hotplug path in this case, would
result in somthing like this:

ibm,dma-window = < 0x80000000 0x00 0x00 0x00 0x00 >;

This will cause linux in the guest to panic, by simply removing and
re-adding the PHB using the drmgr command:

	page = alloc_pages_node(nid, GFP_KERNEL, get_order(sz));
	if (!page)
		panic("iommu_init_table: Can't allocate %ld bytes\n", sz);

The second and maybe more problematic constraint is that the
"interrupt-map" property needs to reference the interrupt controller
node using the very same phandle that SLOF has already exposed to the
guest. QEMU requires SLOF to call the private KVMPPC_H_UPDATE_DT hcall
at some point to know about this phandle. With the latest QEMU and SLOF,
this happens when SLOF gets quiesced. This means that if the PHB gets
hotplugged after CAS but before SLOF quiesce, then we're sure that the
phandle is not known when the hotplug handler is called.

The FDT is only needed when the guest first invokes RTAS to configure
the connector actually, long after SLOF quiesce. Let's postpone the
creation of FDT fragments for PHBs to rtas_ibm_configure_connector().

Since we only need this for PHBs, introduce a new method in the base
DRC class for that. DRC subtypes will be converted to use it in
subsequent patches.

Allow spapr_drc_attach() to be passed a NULL fdt argument if the method
is available. When all DRC subtypes have been converted, the fdt argument
will eventually disappear.

34525595fb target/ppc: Add basic support for "new format" HPTE as found on POWER9
POWER9 (arch v3) slightly changes the HPTE format. The B bits move
from the first to the second half of the HPTE, and the AVPN/ARPN
are slightly shorter.

However, under SPAPR, the hypercalls still take the old format
(and probably will for the foreseable future).

The simplest way to support this is thus to convert the HPTEs from
new to old format when reading them if the MMU model is v3 and there
is no virtual hypervisor, leaving the rest of the code unchanged.

3054b0ca4b target/ppc: Fix ordering of hash MMU accesses
With mttcg, we can have MMU lookups happening at the same time
as the guest modifying the page tables.

Since the HPTEs of the hash table MMU contains two words (or
double worlds on 64-bit), we need to make sure we read them
in the right order, with the correct memory barrier.

Additionally, when using emulated SPAPR mode, the hypercalls
writing to the hash table must also perform the udpates in
the right order.

Note: This part is still not entirely correct

2b9e0a6b94 target/ppc: Re-enable RMLS on POWER9 for virtual hypervisors
Historically the 64-bit server MMU supports two way of configuring the
guest "real mode" mapping:

 - The "RMA" with is a single chunk of physically contiguous
memory remapped as guest real, and controlled by the RMLS
field in the LPCR register and the RMOR register.

 - The "VRMA" which uses special PTEs inserted in the partition
hash table by the hypervisor.

POWER9 deprecates the former, which is reflected by the filtering
done in ppc_store_lpcr() which effectively prevents setting of
the RMLS field.

However, when using fully emulated SPAPR machines, our qemu code
currently only knows how to define the guest real mode memory using
RMLS.

Thus you cannot run a SPAPR machine anymore with a POWER9 CPU
model today.

This works around it with a quirk in ppc_store_lpcr() to continue
allowing the RMLS field to be set when using a virtual hypervisor.

Ultimately we will want to implement configuring a VRMA instead
which will also be necessary if we want to migrate a SPAPR guest
between TCG and KVM but this is a lot more work.

00fd075e18 target/ppc/spapr: Set LPCR:HR when using Radix mode
The HW relies on LPCR:HR along with the PATE to determine whether
to use Radix or Hash mode. In fact it uses LPCR:HR more commonly
than the PATE.

For us, it's also more efficient to do so, especially since unlike
the HW we do not maintain a cache of the current PATE and HV PATE
in a generic place.

Prepare the grounds for that by ensuring that LPCR:HR is set
properly on SPAPR machines.

Another option would have been to use a callback to get the PATE
but this gets messy when implementing bare metal support, it's
much simpler (and faster) to use LPCR.

Since existing migration streams may not have it, fix it up in
spapr_post_load() as well based on the pseudo-PATE entry that
we keep.

The issue with testing asynchronous unplug requests it that they usually
require a running guest to handle the request. However, to test if
unplug of PCI devices works, we can apply a nice little trick on some
architectures:

On system reset, x86 ACPI, s390x and spapr will perform the unplug,
resulting in the device of interest to get deleted and a DEVICE_DELETED
event getting sent.

On s390x, we still get a warning

    warning: Plugging a PCI/zPCI device without the 'zpci' CPU feature

f8154fd22b target/ppc: Detect erroneous condition in interrupt delivery
It's very easy for the CPU specific has_work() implementation
and the logic in ppc_hw_interrupt() to be subtly out of sync.

This can occasionally allow a CPU to wakeup from a PM state
and resume executing past the PM instruction when it should
resume at the 0x100 vector.

This detects if it happens and aborts, making it a lot easier
to catch such bugs when testing rather than chasing obscure
guest misbehaviour.

21c0d66a9c target/ppc: Fix support for "STOP light" states on POWER9
STOP must act differently based on PSSCR:EC on POWER9. When set, it
acts like the P7/P8 power management instructions and wake up at 0x100
based on the wakeup conditions in LPCR.

When PSSCR:EC is clear however it will wakeup at the next instruction
after STOP (if EE is clear) or take the corresponding interrupts (if
EE is set).

3621e2c960 target/ppc: Don't clobber MSR:EE on PM instructions
When issuing a power management instruction, we set MSR:EE
to force ppc_hw_interrupt() into calling powerpc_excp()
to deal with the fact that on P7 and P8, the system reset
caused by the wakeup needs to be generated regardless of
the MSR:EE value (using LPCR only).

This however means that the OS will see a bogus SRR1:EE
value which is a problem. It also prevents properly
implementing P9 STOP "light".

So fix this by instead putting some logic in ppc_hw_interrupt()
to decide whether to deliver or not by taking into account the
fact that we are waking up from sleep.

The LPCR isn't checked as this is done in the has_work() test.

154c69f2b8 target/ppc: Fix nip on power management instructions
Those instructions currently raise an exception from within
the helper. This tends to result in a bogus nip value in
the env context (typically the beginning of the TB). Such
a helper needs a gen_update_nip() first.

This fixes it with a different approach which is to throw the
exception from translate.c instead of the helper using
gen_exception_nip() which does the right thing. Exception
EXCP_HLT is also used instead of POWERPC_EXCP_STOP to effectively
exit from the CPU execution loop.

4300dadc00 tests/cdrom-test: only include isapc cdrom test when g_test_slow()
We are seeing instability on our CI runs which has been there since
the test was introduced. I suspect it triggers more on Travis due to
their heavy load.

4f575c08ca tests/softfloat: always do quick softfloat tests
Some operations take a long time and enabling "-l 2 -r all" can take
more than a day which is stretching the definition of a "slow" test.
Lets default to the quick test and leave a note for those who wish to
run by hand.

0a8b05c7cb Add a gitlab-ci file for Continuous Integration testing on Gitlab
This is very convenient for people like me who store their QEMU git trees
on gitlab.com: Automatic CI pipelines are now run for each branch that is
pushed to the server - useful for some extra-testing before sending PULL-
requests for example. Since the runtime of the jobs is limited to 1h, the
jobs are distributed into multiple pipelines - this way everything finishs
fine within time (ca. 30 minutes currently).

e92a43bb18 tests/docker: peg netmap code to a specific version
Tracking head is always going to be at the whims of the upstream.
Let's use a defined release so things don't magically change under us.
