ppc patch queue 2018-07-03
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

The PPC440 User Manual says that if bit 31 is set, the contents of
CR[CR0] are undefined for indexed store instructions but this form is
not invalid. Other PPC variants confirming to recent ISA where this
bit may be reserved should ignore reserved bits and not raise invalid
instruction exception. In particular, MorphOS has an stwx instruction
with bit 31 set and fails to boot currently because of this. With this
patch it gets further.

The use of GDB breakpoints was broken by b0c2d52 ("target/ppc: convert

Fix it by setting is_jmp, so that we break from the translation loop

In a future patch the machine code will need to retrieve the MMU
information from KVM during machine initialization before the CPUs
are created.
Actually, KVM_PPC_GET_SMMU_INFO is a VM class ioctl, and thus, we
don't need to have a CPU object around. We just need for KVM to
be initialized and use the kvm_state global. This patch just does
that.

Now that we're checking our MMU configuration is supported by KVM,
rather than adjusting it to KVM, it doesn't really make sense to
have a fallback for kvm_get_smmu_info(). If KVM is too old or buggy
to provide the details, we should rather treat this as an error.
This patch thus adds error reporting to kvm_get_smmu_info() and get
rid of the fallback code. QEMU will now terminate if KVM fails to
provide MMU details. This may break some very old setups, but the
simplification is worth the sacrifice.

The FPSCR[FI] bit indicates if the last floating point instruction had a result that was rounded. Each consecutive floating point instruction is suppose to set this bit to the correct value. What currently happens is this bit is not set as often as it should be. I have verified that this is the behavior of a real PowerPC 950. This patch fixes that problem by deciding to set this bit after each floating point instruction.

The store twin case was stubbed out. For now, implement it only within
a serial context, forcing parallel execution to synchronize. It would
be possible to implement with a cmpxchg loop, if we care, but the loose
alignment requirements (simply no crossing 32-byte boundary) might send
us back to the serial context anyway.

Section 1.4 of the Power ISA v3.0B states that both of these
instructions are single-copy atomic. As we cannot (yet) issue
128-bit loads within TCG, use the generic helpers provided.
Since TCG cannot (yet) return a 128-bit value, add a slot within
CPUPPCState for returning the high half of a 128-bit return value.
This solution is preferred to the helper assigning to architectural
registers directly, as it avoids clobbering all TCG live values.

This implements NPT suport for SVM by hooking into
x86_cpu_handle_mmu_fault where it reads the stage-1 page table. Whether
we need to perform this 2nd stage translation, and how, is decided
during vmrun and stored in hflags2, along with nested_cr3 and
nested_pg_mode.
As get_hphys performs a direct cpu_vmexit in case of NPT faults, we need
retaddr in that function. To avoid changing the signature of
cpu_handle_mmu_fault, this passes the value from tlb_fill to get_hphys
via the CPU state.
This was tested successfully via the Jailhouse hypervisor.

Add support for Hyper-V TLB flush which recently got added to KVM.
Just like regular Hyper-V we announce HV_EX_PROCESSOR_MASKS_RECOMMENDED
regardless of how many vCPUs we have. Windows is 'smart' and uses less
expensive non-EX Hypercall whenever possible (when it wants to flush TLB
for all vCPUs or the maximum vCPU index in the vCPU set requires flushing
is less than 64).

tcg_s390_tod_updated() is always called with the iothread being locked
(e.g. from S390TODClass->set() e.g. via HELPER(sck) or on incoming
migration). The helper we call takes the lock itself - bad.
Let's change that by factoring out updating the ckc timer. This now looks
much nicer than having to call a helper from another function.
While touching it we also make sure that env->ckc is updated even if the
new value is -1ULL, for now it would not have been modified in that case.

Let's do this for completeness reason, although we don't support e.g.
PCDIMM/NVDIMM, which would use the alignment for placing the memory
region in guest physical memory. But maybe someday we would want to
support something like this - then we don't forget about this if
allowing multiple allocations in legacy_s390_alloc().
Use the same alignment as we would set in qemu_anon_ram_alloc(). Our
fixed address satisfies this alignment (1MB). This implicitly sets the
alignment of the underlying memory region.

We always allocate at a fixed address, a second allocation can therefore
of course never work. We would simply overwrite mappings.
This can e.g. happen in s390_memory_init(), if trying to allocate more
than > 8TB. Let's just bail out, as there is no need for supporting it
(legacy handling for z/VM).

run_on_cpu() doesn't seem to work reliably until the CPU has been fully
created if the single-threaded TCG main loop is already running.
Therefore, hotplugging a CPU under single-threaded TCG does currently
not work. We should use the direct call instead of going via
run_on_cpu().
So let's use run_on_cpu() for KVM only - KVM requires it due to the initial
CPU reset ioctl. As a nice side effect, we get rid of the ifdef.

Right now, each CPU has its own TOD. Especially, the TOD will differ
based on creation time of a CPU - e.g. when hotplugging a CPU the times
will differ quite a lot, resulting in stall warnings in the guest.
Let's use a single TOD by implementing our new TOD device. Prepare it
for TOD-clock epoch extension.
Most importantly, whenever we set the TOD, we have to update the CKC
timer.

Big values for the TOD/ns clock can result in some overflows that can be
avoided. Not all overflows can be handled however, as the conversion either
multiplies by 4.096 or divided by 4.096.

The rom_ptr() function allows direct access to the ROM blobs that we
load during startup. However, there are currently no checks for the
size of the accesses, so it's currently possible to crash QEMU for
example with:
$ echo "Insane in the mainframe" > /tmp/test.txt
$ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -append xyz
Segmentation fault (core dumped)
$ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -initrd /tmp/test.txt

$ echo -n HdrS > /tmp/hdr.txt
$ sparc64-softmmu/qemu-system-sparc64 -kernel /tmp/hdr.txt -initrd /tmp/hdr.txt
Segmentation fault (core dumped)
We need a possibility to check the size of the ROM area that we want
to access, thus let's add a size parameter to the rom_ptr() function
to avoid these problems.

The xtensa frontend calls get_page_addr_code() from its
itlb_hit_test helper function. This function is really part
of the TCG core's internals, and calling it from a target
helper makes it awkward to make changes to that core code.
It also means that we don't pass the correct retaddr to
tlb_fill(), so we won't correctly handle the case where
an exception is generated.
The helper is used for the instructions IHI, IHU and IPFL.
Change it to call cpu_ldb_code_ra() instead.
