Our implementation of the helper functions for the LD1Q and ST1Q
insns reused the existing DO_LD1_ZPZ_D and DO_ST1_ZPZ_D macros. This
passes the wrong esize (8, not 16) to sve_ldl_z().
Create new macros DO_LD1_ZPZ_Q and DO_ST1_ZPZ_Q which pass the
correct esize, and use them for the LD1Q and ST1Q helpers.

Unlike the "LD1D (scalar + vector)" etc instructions, LD1Q is
vector + scalar. This means that:
* the vector and the scalar register are in opposite fields
in the encoding
* 31 in the scalar register field is XZR, not XSP
The same applies for ST1Q.
This means we can't reuse the trans_LD1_zprz() and trans_ST1_zprz()
functions for LD1Q and ST1Q. Split them out to use their own
trans functions.
Note that the change made here to sve.decode requires the decodetree
bugfix "decodetree: Infer argument set before inferring format" to
avoid a spurious compile-time error about "dtype".

Instead of trying to pack mtedesc into the upper 17 bits of a 32-bit
gvec descriptor, pass the gvec descriptor in the lower 32 bits and
the mte descriptor in the upper 32 bits of a 64-bit operand.
This fixes two bugs:
(1) in gen_sve_ldr() and gen_sve_str() call gen_mte_checkN() with a
length value which is the SVE vector length and can be up to 256
bytes. We don't assert there that it fits in the descriptor, so
we would just fail to do the MTE checks on the right length of memory
if the VL is more than 32 bytes
(2) the new-in-SVE2p1 insns LD3Q, LD4Q, ST3Q, ST4Q also involve
transfers of more than 32 bytes of memory. In this case we would
assert at translate time.
(Note for potential backporting: this commit depends on the previous
"target/arm: Expand the descriptor for SME/SVE memory ops to i64".)

In case of multiple chunks, code in qxl_unpack_chunks() takes size of the
wrong (next in the chain) chunk, instead of using current chunk size.
This leads to wrong number of bytes being copied, and to crashes if next
chunk size is larger than the current one.
Based on the code by Gao Yong.

Currently the tracing 'log' back emits special code to add timestamps
to trace points sent via qemu_log(). This current impl is a bad design
for a number of reasons.
* It changes the QEMU headers, such that 'error-report.h' content
is visible to all files using tracing, but only when the 'log'
backend is enabled. This has led to build failure bugs as devs
rarely test without the (default) 'log' backend enabled, and
CI can't cover every scenario for every trace backend.
* It bloats the trace points definitions which are inlined into
every probe location due to repeated inlining of timestamp
formatting code, adding MBs of overhead to QEMU.
* The tracing subsystem should not be treated any differently
from other users of qemu_log. They all would benefit from
having timestamps present.
* The timestamp emitted with the tracepoints is in a needlessly
different format to that used by error_report() in response
to '-msg timestamp=on'.
This fixes all these issues simply by moving timestamp formatting
into qemu_log, using the same approach as for error_report.
The code before:
static inline void _nocheck__trace_qcrypto_tls_creds_get_path(void * creds, const char * filename, const char * path)
{
if (trace_event_get_state(TRACE_QCRYPTO_TLS_CREDS_GET_PATH) && qemu_loglevel_mask(LOG_TRACE)) {
if (message_with_timestamp) {
struct timeval _now;
gettimeofday(&_now, NULL);
qemu_log("%d@%zu.%06zu:qcrypto_tls_creds_get_path " "TLS creds path creds=%p filename=%s path=%s" "\n",
qemu_get_thread_id(),
(size_t)_now.tv_sec, (size_t)_now.tv_usec
, creds, filename, path);
} else {
qemu_log("qcrypto_tls_creds_get_path " "TLS creds path creds=%p filename=%s path=%s" "\n", creds, filename, path);
}
}
}

It has been awhile since I actively did anything for qemu-ppc aside from
reading the qemu-ppc inbox a couple of times each month. It's not enough
to justify a reviewer role, let alone being a maintainer.
Given that we're doing qemu-ppc maintainership changes across the board
I'll take the opportunity and remove myself from the premises too. Feel

this moment I'm no longer able to keep up with qemu-ppc activities.

When either the postcopy or return path capabilities are

If either of those capabilities are enabled, the migration

When TLS 1.3 is negotiated on a TLS session, GNUTLS will perform
automatic rekeying of the session after 16 million records. This
is done for all algorithms except CHACHA20_POLY1305 which does
not require rekeying.
Unfortunately the rekeying breaks GNUTLS' promise that it is safe
to use a gnutls_session_t object concurrently from multiple threads
if they are exclusively calling gnutls_record_send/recv.
This patch implements a workaround for QEMU that adds a mutex lock
around any gnutls_record_send/recv call to serialize execution
within GNUTLS code. When GNUTLS calls into the push/pull functions
we can release the lock so the OS level I/O calls can at least
have some parallelism.
The big downside of this is that the actual encryption/decryption
code is fully serialized, which will halve performance of that
cipher operations if two threads are contending.
The workaround is not enabled by default, since most use of GNUTLS
in QEMU does not tickle the problem, only non-multifd migration
with a return path open is affected. Fortunately the migration
code also won't trigger the halving of performance, since only
the outbound channel diretion needs to sustain high data rates,
the inbound direction is low volume.

Commit a2260983c655 ("hvf: arm: Add support for GICv3") added GICv3 support
by implementing emulation for a few system registers. ICC_RPR_EL1 was
defined but not plugged in the sysreg handlers (for no good reason).
Fix it.

Quoting Peter Maydell:
" hvf_sysreg_read_cp() and hvf_sysreg_write_cp() do not check the .access
field of the ARMCPRegInfo to ensure that they forbid writes to registers
that are marked with a .access field that says they're read-only (and
ditto reads to write-only registers). "
Before we add more registers in GIC sysreg handlers, let's get it correct
by adding the .access checks to hvf_sysreg_read_cp() and
hvf_sysreg_write_cp(). With that, a sysreg access with invalid permission
will result in an UNDEFINED exception.

For the LD1Q instruction (gather load of quadwords) we use the
LD1_zprz pattern with MO_128 elements. At this element size there is
no signed vs unsigned distinction, and we only set the 'u' bit in the
arg_LD1_zprz struct because we share the code and decode struct with
smaller element sizes.
However, we set u=0 in the decode pattern line but then accidentally
asserted that it was 1 in the trans function. Since our usual convention
is that the "default" is unsigned and we only mark operations as signed
when they really do need to extend, change the decode pattern line to
set u=1 to match the assert.

The FMAXNMQV and FMINNMQV insns use the default NaN as their identity
value for inactive source vector elements. We open-coded this in
sve_helper.c, hoping to avoid a function call. However, this fails
to account for FPCR.AH=1 changing the default NaN value to set the
sign bit. Use a call to floatN_default_nan() to obtain this value.

In the part of the SVE DO_REDUCE macro used by the SVE2p1 FMAXQV,
FMINQV, etc insns, we incorrectly applied the H() macro twice when
calculating an offset to add to the vn pointer. This has no effect
on little-endian hosts but on big-endian hosts the two invocations
will cancel each other out and we will access the wrong part of the
array.
The "s * 16" part of the expression is already aligned, so we only
need to use the H macro on the "e". Correct the macro usage.

When we implemented the FMAXQV and FMINQV insns we accidentally
inverted the sense of the FPCR.AH test, so we gave the AH=1 behaviour
when FPCR.AH was zero, and vice-versa. (The difference is limited to
handling of negative zero and NaN inputs.)

FEAT_SVE_B16B16 adds a bfloat16 version of the FMUL insn in the
floating-point multiply (indexed) instruction group. The encoding
is slightly bespoke; in our implementation we use MO_8 to indicate
bfloat16, as with the other B16B16 insns.

FEAT_SVE_B16B16 adds bfloat16 versions of the SVE floating point
(predicated) instructions, which are encoded via sz=0b00. Add the
BFMAX and BFMIN insns. These have separate behaviour for AH=1 and
AH=0; we have already implemented the AH=1 helper for the SME2
versions of these insns.

FEAT_SVE_B16B16 adds bfloat16 versions of the SVE floating point
(predicated) instructions, which are encoded via sz=0b00.
Add BFADD, BFSUB, BFMUL, BFMAXNM, BFMINNM; these are all the insns
in this group which do not change behaviour for AH=1.
We will deal with BFMAX/BFMIN (which do have different AH=1
behaviour) in a following commit.

Coverity Scan noted an unusual pattern in the
MAX78000 aes device, with duplicated calls to
set_decrypt. This commit adds a comment noting
why the implementation is correct.
