Laurent Vivier c00dc6750f replace muldiv64(a, b, c) by (uint64_t)a * b / c
When "a" and "b" are 32bit values, we don't have to cast
them to 128bit, 64bit is enough.

This patch is the result of coccinelle script
scripts/coccinelle/simplify_muldiv64.cocci

Laurent Vivier 3498686220 The only 64bit parameter of muldiv64() is the first one.
muldiv64() is "uint64_t muldiv64(uint64_t a, uint32_t b, uint32_t c)"

Some time it is used as muldiv64(uint32_t a, uint64_t b, uint32_t c)"

Peter Wu 96165b9eb4 gdbstub: set listen backlog to 1
Avoid possible connection drops on Linux (when tcp_syncookies is
disabled) or fallbacks to SYN cookies with the following kernel warning:

    TCP: request_sock_TCP: Possible SYN flooding on port 1234. Sending cookies.  Check SNMP counters.

Since Linux 4.4 (ef547f2ac16b "tcp: remove max_qlen_log"), a backlog of
zero is really treated as the "queue length for completely established
sockets waiting to be accepted" (listen(2)). This is apparently a valid
interpretation of an "implementation-defined minimum value" for a
backlog value of 0 (listen(3p)). Previous kernels would use 8 as
minimum value, but that is no longer the case.

Eduardo Habkost d5aebef884 docker: Don't use eval trick on Makefile
The eval trick for defining DOCKER_SRC_COPY doesn't do anything
useful, as DOCKER_SRC_COPY is immediately expanded just after it
is defined, and CUR_TIME is already defined using ":=". Simply
define it using ":=" so it is evaluated only once.

The eval trick was also triggering an weird error on Travis builds:
  qemu/tests/docker/Makefile.include:34: *** unterminated variable reference.  Stop.

The issue is not easily reproducible (maybe it's a bug in some
versions of Make), but it is avoided if removing the eval trick.

In a similar vein to commit ee2bdc33c9
("throttle: refuse bps_max/iops_max without bps/iops") it is likely that
the user made a configuration error if iops-size has been set but no
iops limit has been set.

Print an error message so the user can check their throttling
configuration.  They should either remove iops-size if they don't want
any throttling or specify one of iops-total, iops-read, or iops-write.

Fam Zheng 3482958383 virtio-blk: Remove op blocker for dataplane
Block layer is prepared to unspecialize dataplane, an evidence is this
almost complete list of unblocked operations. It has all types except
two (actually three if DATAPLANE itself counts but blockdev.c makes sure
attaching twice is not possible): MIRROR_TARGET and BACKUP_TARGET.

blockdev-mirror refuses to start if target is attached, so the first is
not a problem.

By removing BACKUP_TARGET, blockdev-backup will become permissive to
write to a virtio-blk dataplane disk, but that is not worse than
non-dataplane given the latter is already possible. In either case,
blockdev.c always checks the target and source are on the same
AioContext, or bring them together if possible.

Greg Kurz c02d7030c3 virtio: move bi-endian target support to a single location
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.

Also as 'TCPA' is allocated 0 filled, there is no point
in calculating always 0 log_area_start_address and set
tcpa->log_area_start_address to it since the field should
always point to start of ACPI_BUILD_TPMLOG_FILE.

Igor Mammedov 0058c08238 pc: use AcpiDeviceIfClass.send_event to issue GPE events
it reduces number of args passed in handlers by 1 and
a number of used proxy wrappers saving ~20LOC.
Also it allows to make cpu/mem hotplug code more
universal as it would allow ARM to reuse it without
rewrite by providing its own send_event callback
to trigger events usiong GPIO instead of GPE
as fixed hadrware ACPI model doen't have GPE at all.

Igor Mammedov eaf23bf794 acpi: extend ACPI interface to provide send_event hook
send_event() hook will allow to send ACPI event in
a target specific way (GPE or GPIO based impl.)
it will also simplify proxy wrappers in piix4pm/ich9
that access ACPI regs and SCI which are part of
piix4pm/lcp_ich9 devices and call acpi_foo() API directly.

Corey Minyard 15139b8ef0 ipmi: rework the fwinfo to be fetched from the interface
Instead of scanning IPMI devices from a fwinfo list, allow
the fwinfo to be fetched from the IPMI interface class.
Then the code looking for IPMI fwinfo can scan devices on a
bus and look for ones that implement the IPMI class.

This will let the ACPI scope be defined by the calling
code so the IPMI code doesn't have to know the scope.

Igor Mammedov 76bdd24ec0 pc: acpi: cpuhp-legacy: switch ProcessorID to possible_cpus idx
In legacy cpu-hotplug ProcessorID == APIC ID is used
in MADT and cpu-hotplug AML. It was fine as both
are 8bit and unique. Spec depricated Processor()
with corresponding ProcessorID and advises to use
Device() and UID instead of it.

However UID is just 32bit and it can't fit ARM's
arch_id(MPIDR) which is 64bit. Also in case of
sparse arch_id() distribution, managment/lookup
of maps by arch_id(APIC ID/MPIDR) becomes complex
and expensive.

In preparation to common CPU hotplug with ARM
and to simplify lookup in possible_cpus[] map
switch ProcessorID to possible_cpus index in
MADT.

Legacy cpu-hotplug considerations:
HW interface of it is APIC ID based bitmask so
it's impossible to change, also CPON package in
AML also APIC ID based as well all the methods.

To avoid massive rewrite of AML keep is so and
just break assumption that ProcessorID == APIC ID,
ammending CPU_MAT_METHOD to accept APIC ID and
possible_cpus index, it needs them both to patch
MADT entry template. Also switch to possible_cpus
index Processor(ProcessorID) AML.
That way changes to MADT/AML are minimal and kept
inside AML/MADT not affecting external interfaces.
