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.

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.

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

Second, the "start <= ra && (start + nr - 32) > ra" condition for the

Here is the description of the mcrfs instruction from the PowerPC Architecture
Book, Version 2.02, Book I: PowerPC User Instruction Set Architecture
(http://www.ibm.com/developerworks/systems/library/es-archguide-v2.html), found
on page 120:
The contents of FPSCR field BFA are copied to Condition Register field BF.
All exception bits copied are set to 0 in the FPSCR. If the FX bit is
copied, it is set to 0 in the FPSCR.
Special Registers Altered:
CR field BF
FX OX (if BFA=0)
UX ZX XX VXSNAN (if BFA=1)
VXISI VXIDI VXZDZ VXIMZ (if BFA=2)
VXVC (if BFA=3)
VXSOFT VXSQRT VXCVI (if BFA=5)
However, currently every bit in FPSCR field BFA is set to 0, including ones not
on that list.
This can be seen in the following simple C program:
#include <fenv.h>
#include <stdio.h>
int main(int argc, char **argv) {
int ret;
ret = fegetround();
printf("Current rounding: %d\n", ret);
ret = fesetround(FE_UPWARD);
printf("Setting to FE_UPWARD (%d): %d\n", FE_UPWARD, ret);
ret = fegetround();
printf("Current rounding: %d\n", ret);
ret = fegetround();
printf("Current rounding: %d\n", ret);
return 0;
}
which gave the output (before this commit):
Current rounding: 0
Setting to FE_UPWARD (2): 0
Current rounding: 2
Current rounding: 0
instead of (after this commit):
Current rounding: 0
Setting to FE_UPWARD (2): 0
Current rounding: 2
Current rounding: 2
The relevant disassembly is in fegetround(), which, on my system, is:
__GI___fegetround:
<+0>: mcrfs cr7, cr7
<+4>: mfcr r3
<+8>: clrldi r3, r3, 62
<+12>: blr
What happens is that, the first time fegetround() is called, FPSCR field 7 is
retrieved. However, because of the bug in mcrfs, the entirety of field 7 is set
to 0, which includes the rounding mode.
There are other issues this will fix, such as condition flags not persisting
when they should if read, and if you were to read a specific field with some
exception bits set, but no others were set in the entire register, then the
bits would be cleared correctly, but FEX/VX would not be updated to 0 as they
should be.

Currently, the ppc_hash64_page_shift() function looks up a page size based
on information in an SLB entry. It open codes the bit translation for
existing CPUs, however different CPU models can have different SLB
encodings. We already store those in the 'sps' table in CPUPPCState, but
we don't currently enforce that that actually matches the logic in
ppc_hash64_page_shift.
This patch reworks lookup of page size from SLB in several ways:
* ppc_store_slb() will now fail (triggering an illegal instruction
exception) if given a bad SLB page size encoding
* On success ppc_store_slb() stores a pointer to the relevant entry in
the page size table in the SLB entry. This is looked up directly from
the published table of page size encodings, so can't get out ot sync.
* ppc_hash64_htab_lookup() and others now use this precached page size
information rather than decoding the SLB values
* Now that callers have easy access to the page_shift,
ppc_hash64_pte_raddr() amounts to just a deposit64(), so remove it and
have the callers use deposit64() directly.

becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when
this occurs.
The operation of the Virtual Time Base has the following additional

1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of
the Virtual Time Base.
2. Copying the contents of a GPR to the Virtual Time Base replaces the
contents of the Virtual Time Base with the contents of the GPR.

This adds handling of the RESOURCE_ADDR_TRANS_MODE resource from
the H_SET_MODE, for POWER8 (PowerISA 2.07) only.
This defines AIL flags for LPCR special register.
This changes @excp_prefix according to the mode, takes effect in TCG.
This turns support of a new capability PPC2_ISA207S flag for TCG.
