David Hildenbrand 19d70587b5 target/s390x: Allow to enable "idtes" feature for TCG
STFL bit 4 and 5 are just indications to the guest, which TLB entries an
IDTE call will clear. These are performance indicators for the guest.

STFL bit 4:
    INVALIDATE DAT TABLE ENTRY (IDTE) performs
    the invalidation-and-clearing operation by
    selectively clearing TLB segment-table entries
    when a segment-table entry or entries are
    invalidated. IDTE also performs the clearing-by-
    ASCE operation. Unless bit 4 is one, IDTE simply
    purges all TLBs. Bit 3 is one if bit 4 is one.

We can simply set STFL bit 4 ("idtes") and still purge the complete TLB.
Purging more than advertised is never bad. E.g. Linux doesn't even care
about this bit. We can optimized this later.
This is helpful, as the z9 base model contains this facility.

STFL bit 5 (clearing TLB region-table-entries) was never implemented on
real HW, therefore we can simply ignore it for now.

Daniel P. Berrange 1ce36bfe64 i386: expose "TCGTCGTCGTCG" in the 0x40000000 CPUID leaf
Currently when running KVM, we expose "KVMKVMKVM\0\0\0" in
the 0x40000000 CPUID leaf. Other hypervisors (VMWare,
HyperV, Xen, BHyve) all do the same thing, which leaves
TCG as the odd one out.

The CPUID signature is used by software to detect which
virtual environment they are running in and (potentially)
change behaviour in certain ways. For example, systemd
supports a ConditionVirtualization= setting in unit files.
The virt-what command can also report the virt type it is
running on

Currently both these apps have to resort to custom hacks
like looking for 'fw-cfg' entry in the /proc/device-tree
file to identify TCG.

This change thus proposes a signature "TCGTCGTCGTCG" to be
reported when running under TCG.

To hide this, the -cpu option tcg-cpuid=off can be used.

Alex Bennée b29fd33db5 target/arm: use DISAS_EXIT for eret handling
Previously DISAS_JUMP did ensure this but with the optimisation of
8a6b28c7 (optimize indirect branches) we might not leave the loop.
This means if any pending interrupts are cleared by changing IRQ flags
we might never get around to servicing them. You usually notice this
by seeing the lookup_tb_ptr() helper gainfully chaining TBs together
while cpu->interrupt_request remains high and the exit_request has not
been set.

This breaks amongst other things the OPTEE test suite which executes
an eret from the secure world after a non-secure world IRQ has gone
pending which then never gets serviced.

Instead of using the previously implied semantics of DISAS_JUMP we use
DISAS_EXIT which will always exit the run-loop.

Alex Bennée 0b609cc128 target/arm: use gen_goto_tb for ISB handling
While an ISB will ensure any raised IRQs happen on the next
instruction it doesn't cause any to get raised by itself. We can
therefore use a simple tb exit for ISB instructions and rely on the
exit_request check at the top of each TB to deal with exiting if
needed.

Peter Maydell 8d92e26b45 target/arm: Make Cortex-M3 and M4 default to 8 PMSA regions
The Cortex-M3 and M4 CPUs always have 8 PMSA MPU regions (this isn't
a configurable option for the hardware).  Make the default value of
the pmsav7-dregion property be set per-cpu, so we don't need to have
every user of these CPUs set it manually.  (The existing default of
16 is correct for the other PMSAv7 core, the Cortex-R5.)

This fixes a bug where we were creating the M3 and M4 with
too many regions; most guest software would not notice or
care, though, since it would just not use the registers
associated with the unexpected extra regions.

Cédric Le Goater 346ebfc6fb target/ppc: fix CPU hotplug when radix is enabled (TCG)
But when a guest initializes radix mode, it issues a H_REGISTER_PROC_TBL
to update the LPCR of all CPUs. Hot-plugged CPUs inherit from the same
setting under KVM but not under TCG. So, Let's check for radix and update
the default LPCR to keep new CPUs in sync.

David Gibson b55d295e3e pseries: Allow HPT resizing with KVM
So far, qemu implements the PAPR Hash Page Table (HPT) resizing extension
with TCG.  The same implementation will work with KVM PR, but we don't
currently allow that.  For KVM HV we can only implement resizing with the
assistance of the host kernel, which needs a new capability and ioctl()s.

This patch adds support for testing the new KVM capability and implementing
the resize in terms of KVM facilities when necessary.  If we're running on
a kernel which doesn't have the new capability flag at all, we fall back to
testing for PR vs. HV KVM using the same hack that we already use in a
number of places for older kernels.

David Gibson 0b0b831016 pseries: Implement HPT resizing
This patch implements hypercalls allowing a PAPR guest to resize its own
hash page table.  This will eventually allow for more flexible memory
hotplug.

The implementation is partially asynchronous, handled in a special thread
running the hpt_prepare_thread() function.  The state of a pending resize
is stored in SPAPR_MACHINE->pending_hpt.

The H_RESIZE_HPT_PREPARE hypercall will kick off creation of a new HPT, or,
if one is already in progress, monitor it for completion.  If there is an
existing HPT resize in progress that doesn't match the size specified in
the call, it will cancel it, replacing it with a new one matching the
given size.

The H_RESIZE_HPT_COMMIT completes transition to a resized HPT, and can only
be called successfully once H_RESIZE_HPT_PREPARE has successfully
completed initialization of a new HPT.  The guest must ensure that there
are no concurrent accesses to the existing HPT while this is called (this
effectively means stop_machine() for Linux guests).

For now H_RESIZE_HPT_COMMIT goes through the whole old HPT, rehashing each
HPTE into the new HPT.  This can have quite high latency, but it seems to
be of the order of typical migration downtime latencies for HPTs of size
up to ~2GiB (which would be used in a 256GiB guest).

In future we probably want to move more of the rehashing to the "prepare"
phase, by having H_ENTER and other hcalls update both current and
pending HPTs.  That's a project for another day, but should be possible
without any changes to the guest interface.

David Gibson 30f4b05bd0 pseries: Stubs for HPT resizing
This introduces stub implementations of the H_RESIZE_HPT_PREPARE and
H_RESIZE_HPT_COMMIT hypercalls which we hope to add in a PAPR
extension to allow run time resizing of a guest's hash page table.  It
also adds a new machine property for controlling whether this new
facility is available.

For now we only allow resizing with TCG, allowing it with KVM will require
kernel changes as well.

Finally, it adds a new string to the hypertas property in the device
tree, advertising to the guest the availability of the HPT resizing
hypercalls.  This is a tentative suggested value, and would need to be
standardized by PAPR before being merged.

The SIGP SET ARCHITECTURE instruction is simply rejected. Linux as guest

The new handling is just like already being in z/Architecture mode.

We'll not try to fake absence of this facility, but still not indicate
the facility in case some strange CPU model turned z/Architecture off
completely (which doesn't work either way but let's us see how a
guest would react on a lack of this facility).

For ais bit, we only provide it in the full cpu model beginning with
zEC12 and defer its enablement in the default cpu model to a later point
in time. At the same time, disable them for 2.9 and older machines.

Because of introducing AIS facility, we could check if it's enabled to

Janosch Frank 03f47ee49e s390x/kvm: Rework cmma management
Let's keep track of cmma enablement and move the mem_path check into
the actual enablement. This now also warns users that do not use
cpu-models about disabled cmma when using huge pages.

Alistair Francis 3dc6f86936 Convert error_report() to warn_report()
Convert all uses of error_report("warning:"... to use warn_report()
instead. This helps standardise on a single method of printing warnings
to the user.

All of the warnings were changed using these two commands:
    find ./* -type f -exec sed -i \
      's|error_report(".*warning[,:] |warn_report("|Ig' {} +

Indentation fixed up manually afterwards.

The test-qdev-global-props test case was manually updated to ensure that
this patch passes make check (as the test cases are case sensitive).
