Paolo's recent cpu.h cleanups broke legacy virtio for ppc64 LE guests (and
arm BE guests as well, even if I have not verified that). Especially, commit
"33c11879fd42 qemu-common: push cpu.h inclusion out of qemu-common.h" has
the side-effect of silently hiding the TARGET_IS_BIENDIAN macro from the
virtio memory accessors, and thus fully disabling support of endian changing
targets.
To be sure this cannot happen again, let's gather all the bi-endian bits
where they belong in include/hw/virtio/virtio-access.h.
The changes in hw/virtio/vhost.c are safe because vhost_needs_vring_endian()
is not called on a hot path and non bi-endian targets will return false
anyway.
While here, also rename TARGET_IS_BIENDIAN to be more precise: it is only for
legacy virtio and bi-endian guests.

Since at least the 2.05 architecture, the slbia instruction takes an
IH field in the opcode to provide some control on the effect of the
slbia on the ERATs (level-1 TLB).
We can safely ignore it as we always flush the whole qemu TLB but
we should allow the bits in the decode.

This ports the existing 64-bit mechanism to 32-bit, thus series
of 64 tlbie's followed by a sync like some versions of Darwin
(ab)use will result in a single flush.
We apply a pending flush on any sync instruction though, as Darwin
doesn't use tlbsync on non-SMP systems.

The processor only uses some bits of the address and invalidates an
entire congruence class. Some OSes such as Darwin and HelenOS take
advantage of this and occasionally invalidate the entire TLB by just
doing a series of 64 consecutive tlbie for example.
Our code tries to be too smart here only invalidating a segment
congruence class (ie, allowing more address bits to be relevant
in the invalidation), this fails miserably on those OSes.
Instead don't bother, do like ppc64 and blow the whole tlb when tlbie
is executed.

We used to always flush the TLB when changing relocation mode in
MSR:IR and MSR:DR (ie. MMU on/off for Instructions and Data).
We don't anymore since we have split mmu_idx for instruction and data.
However, since we hard code the mmu_idx in the translated code, we
now need to also make sure MSR:IR and MSR:DR are part of the hflags
used to tag translated code, so that we use different translated
code for different MMU settings.
Darwin gets hurt by this problem.

With specification at hand from the reference manual from Freescale
http://cache.nxp.com/files/32bit/doc/ref_manual/SPEPEM.pdf , I have found a fix
to efscmp* instructions handling in QEMU.
efscmp* instructions in QEMU set crD (Condition Register nibble) values as
(0b0100 << 2) = 0b10000 (consider the HELPER_SINGLE_SPE_CMP macro which left
shifts the value returned by efscmp* handler by 2 bits). A value of 0b10000 is
not correct according the to the reference manual.
The reference manual expects efscmp* instructions to return a value of 0bx1xx.
Please find attached a patch which disables left shifting in
HELPER_SINGLE_SPE_CMP macro. This macro is used by efscmp* and efstst*
instructions only. efstst* instruction handlers, in turn, call efscmp* handlers
too.
*Explanation:*
Traditionally, each crD (condition register nibble) consist of 4 bits, which is
set by comparisons as follows:
crD = W X Y Z
where
W = Less than
X = Greater than
Y = Equal to
However, efscmp* instructions being a special case return a binary result.
(efscmpeq will set the crD = 0bx1xx iff when op1 == op2 and 0bx0xx otherwise;
i.e. there is no notion of different crD values based on Less than, Greater
than and Equal to).
This effectively means that crD will store a "Greater than" comparison result
iff efscmp* instruction comparison is TRUE. Compiler exploits this feature by
checking for "Branch if Less than or Equal to" (ble instruction) OR "Branch if
Greater than" (bgt instruction) for Branch if FALSE OR Branch if TRUE
respectively after an efscmp* instruction. This can be seen in a assembly code
snippet below:
27 if (__real__ x != 3.0f || __imag__ x != 4.0f)
10000498: lwz r10,8(r31)
1000049c: lis r9,16448

On ppc64 especially, we flush the tlb on any slbie or tlbie instruction.
However, those instructions often come in bursts of 3 or more (context
switch will favor a series of slbie's for example to an slbia if the
SLB has less than a certain number of entries in it, and tlbie's can
happen in a series, with PAPR, H_BULK_REMOVE can remove up to 4 entries
at a time.
Doing a tlb_flush() each time is a waste of time. We end up doing a memset
of the whole TLB, reloading it for the next instruction, memset'ing again,
etc...
Those instructions don't have to take effect immediately. For slbie, they
can wait for the next context synchronizing event. For tlbie, the next
tlbsync.
This implements batching by keeping a flag that indicates that we have a
TLB in need of flushing. We check it on interrupts, rfi's, isync's and
tlbsync and flush the TLB if needed.
This reduces the number of tlb_flush() on a boot to a ubuntu installer
first dialog screen from roughly 360K down to 36K.

The KVM API restricts vcpu ids to be < KVM_CAP_MAX_VCPUS. On PowerPC
targets, depending on the number of threads per core in the host and
in the guest, some topologies do generate higher vcpu ids actually.
When this happens, QEMU bails out with the following error:
kvm_init_vcpu failed: Invalid argument
The KVM_CREATE_VCPU ioctl has several EINVAL return paths, so it is
not possible to fully disambiguate.
This patch adds a check in the code that computes vcpu ids, so that
we can detect the error earlier, and print a friendlier message instead
of calling KVM_CREATE_VCPU with an obviously bogus vcpu id.

ppc_hash64_set_external_hpt() was added in e5c0d3c "target-ppc: Add helpers
for updating a CPU's SDR1 and external HPT". This helper contains a
cpu_synchronize_state() since it may need to push state back to KVM
afterwards.
This turns out to break things when it is used in the reset path, which is
the only current user. It appears that kvm_vcpu_dirty is not being set
early in the reset path, so the cpu_synchronize_state() is clobbering state
set up by the early part of the cpu reset path with stale state from KVM.
This may require some changes to the generic cpu reset path to fix
properly, but as a short term fix we can just remove the
cpu_synchronize_state() from ppc_hash64_set_external_hpt(), and require any
non-reset path callers to do that manually.

We are inconsistent with the type of tb->flags: usage varies loosely
between int and uint64_t. Settle to uint32_t everywhere, which is
superior to both: at least one target (aarch64) uses the most significant
bit in the u32, and uint64_t is wasteful.

The range checks in the LSWX instruction are completely insufficient:
They do not take the wrap-around case into account, and the check
"reg < rx" should be "reg <= rx" instead. Fix it by using the new
lsw_reg_in_range() helper function that is already used for LSWI, too.
Then there is a second problem: In case the INVAL exception is generated,
the NIP value is wrong, it currently points to the instruction before
the LSWX instruction. This is because gen_lswx() already decreases the
NIP value by 4 (to be prepared for page fault exceptions), and
powerpc_excp() later decreases it again by 4 while handling the program
exception. So to get this right, we've got to undo the "- 4" from
gen_lswx() here before calling helper_raise_exception_err().

There are two issues: First, the number of registers that are used has

Second, the "start <= ra && (start + nr - 32) > ra" condition for the
wrap-around case is wrong: It has to be tested with "||" instead of "&&".
