Here's a last minue pull request before today's soft freeze. Ideally
I would have sent this earlier, but I was waiting for a couple of
extra fixes I knew were close. And the freeze crept up on me, like
always.
Most of the changes here are bugfixes in any case. There are some
cleanups as well, which have been in my staging tree for a little
while. There are a couple of truly new features (some extensions to
the sam460ex platform), but these are low risk, since they only affect
a new and not really stabilized machine type anyway.
Higlights are:
* Mac platform improvements from Mark Cave-Ayland
* Sam460ex improvements from BALATON Zoltan et al.
* XICS interrupt handler cleanups from Cédric Le Goater
* TCG improvements for atomic loads and stores from Richard
Henderson
* Assorted other bugfixes

changes here. virtio-vga and secondary-vga already set global_vmstate

Message-id: 20180702162752.29233-1-kraxel@redhat.com
Fetching qtd with the NULL address most likely makes no sense so from now
on, we handle it this case similarly as if the terminate (T) bit is not
set, which is already an exception as according to section 3.6 of the EHCI
spec there is no T bit defined for the current_qtd field.
The spec is a bit vague on how an EHCI driver should initialize these
fields: "The general operational model is that the host controller can
detect whether the overlay area contains a description of an active
transfer" (p. 49). QEMU primarily uses the QTD_TOKEN_ACTIVE bit of the
queue header to infer the activity state but there are other ways
conceivable.
This change allows QEMU to boot further into AmigaOS. The public available
version of the EHCI driver recycles queue heads in some rare conditions but
only clears the current_qtd field but not the status field. This works with
many available EHCI PCI cards but e.g., not with the Freescale USB
controller's found on the P5040. On the emulated EHCI controller of QEMU
the consequence is that some garbage was read in, which resulted in a
reset of the controller. This change fixes the problem.

Drivers for this card exists on PPC-based AmigaOS guests so it is useful to
allow users to emulate the graphics card for PPC machines.
As cirrus vga is currently preferred over std(vga) in absence of any user
choice, this change also sets the default display of spapr machines to
std as otherwise qemu refuses to start these machines. Not specifying an
explicit graphics mode is for instance done by 'make check'.

It is currently not possible to run a pseries-2.12 or older machine
with HV KVM. QEMU prints the following and exits right away.
qemu-system-ppc64: KVM doesn't support for base page shift 34
The "hpt-max-page-size" capability was recently added to spapr to hide
host configuration details from HPT mode guests. Its default value for
newer machine types is 64k.
For backwards compatibility, pseries-2.12 and older machine types need
a different value. This is handled as usual in a class init function.
The default value is 16G, ie, all page sizes supported by POWER7 and
newer CPUs, but HV KVM requires guest pages to be hpa contiguous as
well as gpa contiguous. The default value is the page size used to
back the guest RAM in this case.
Unfortunately kvmppc_hpt_needs_host_contiguous_pages()->kvm_enabled() is
called way before KVM init and returns false, even if the user requested
KVM. We thus end up selecting 16G, which isn't supported by HV KVM. The
default value must be set during machine init, because we can safely
assume that KVM is initialized at this point.
We fix this by moving the logic to default_caps_with_cpu(). Since the
user cannot pass cap-hpt-max-page-size=0, we set the default to 0 in
the pseries-2.12 class init function and use that as a flag to do the
real work.
