Laszlo Ersek f2a1ae45d8 hw/acpi/vmgenid: prevent device realization on pre-2.5 machine types
The WRITE_POINTER linker/loader command that underlies VMGENID depends on
commit baf2d5bfba ("fw-cfg: support writeable blobs", 2017-01-12), which
in turn depends on fw_cfg DMA.

DMA for fw_cfg is enabled in 2.5+ machine types only (see commit
e6915b5f3a, "fw_cfg: unbreak migration compatibility for 2.4 and earlier
machines", 2016-02-18).

Ben Warren d03637bcfb ACPI: Add Virtual Machine Generation ID support
This implements the VM Generation ID feature by passing a 128-bit
GUID to the guest via a fw_cfg blob.
Any time the GUID changes, an ACPI notify event is sent to the guest

The user interface is a simple device with one parameter:
 - guid (string, must be "auto" or in UUID format
   xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

This allows them to be centrally initialized and destroyed

The "AcpiBuildTables.vmgenid" array will be used to construct the

Its contents will be linked into fw_cfg after being built on the
pc_machine_done() -> acpi_setup() -> acpi_build() call path, and dropped
without use on the subsequent, guest triggered, acpi_build_update() ->
acpi_build() call path.

Marc-André Lureau 675f22c6d3 bus: do not unref hotplug handler
Apparently, none of the bus owner give a reference to the hotplug
handler property, do not unref it on bus release.

Furthermore, a bus is allowed to be its own hotplug handler, which can
be seen in qbus_set_bus_hotplug_handler() function. However, in this
case, the reference can't be given to the property, or this will create
a cyclic dependency and the bus will never be free.

Each bus owner should manage the lifecycle of the hotplug handler.

Igor Mammedov f0c9d64a68 pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twice
PCI hotplug for bridges was introduced only since 2.0 however
  acpi_set_bsel()->object_property_add_uint32_ptr(bus, ACPI_PCIHP_PROP_BSEL)
didn't take in account that for legacy mode (1.7) when
PCI hotplug for bridges is unavailable and ACPI_PCIHP_PROP_BSEL property
the only bus "PCI.0' has been created earlier at acpi_pcihp_init() time.

We managed to live with it only because of error rised by adding
a duplicate property in acpi_set_bsel() has been ignored which
resulted in useless leaking of just allocated (int)bus_bsel.

Issue affects only 1.7 machine type as ACPI tables supported by
QEMU were introduced at that time, but there wasn't PCI hotplug
for bridges till the next release (2.0).

Fix it by removing duplicate ACPI_PCIHP_PROP_BSEL intialization
in acpi_pcihp_init() and doing it only in one place acpi_set_pci_info().

PS:
do not ignore error returned by object_property_add_uint32_ptr()
and abort QEMU since it's programming error which should be fixed
instead of being ignored.

Igor Mammedov 80db0e7822 memhp: don't generate memory hotplug AML if it's not enabled/supported
That reduces DSDT by 910 bytes when memory hotplug
isn't enabled.

While doing so drop intermediate variables/arguments
passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making
it local to memory_hotplug.c, hardcoding it there as
it can't change.

Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through
intermediate variables/arguments where it's not needed.
Instead initialize in module static variable when MMIO
region is mapped and use that within memory_hotplug.c
whenever it's required.
That way MMIO base specified only at one place and AML
with MMIO would always use the same value.

Haozhong Zhang 53000638f2 acpi: fix assert failure caused by commit 35c5a52d
Commit 35c5a52d "acpi: do not use TARGET_PAGE_SIZE" changed struct
NvdimmDsmIn from a variable-size structure to a fixed-size structure of
4096 bytes. It forgot to adjust an assert in
nvdimm_dsm_set_label_data(..., NvdimmDsmIn *in, ...):
    assert(sizeof(*in) + sizeof(*set_label_data) + set_label_data->length <=
           4096);
which could crash QEMU when guest writes NVDIMM labels.

Fix it by replacing sizeof(*in) by offsetof(NvdimmDsmIn, arg3).

Xiao Guangrong 806864d9a8 nvdimm acpi: introduce _FIT
_FIT is required for hotplug support, guest will inquire the updated
device info from it if a hotplug event is received

As FIT buffer is not completely mapped into guest address space, so a
new function, Read FIT whose UUID is UUID
648B9CF2-CDA1-4312-8AD9-49C4AF32BD62, handle 0x10000, function index
is 0x1, is reserved by QEMU to read the piece of FIT buffer. The buffer
is concatenated before _FIT return

Xiao Guangrong 75b0713e18 nvdimm acpi: introduce fit buffer
The buffer is used to save the FIT info for all the presented nvdimm
devices which is updated after the nvdimm device is plugged or
unplugged. In the later patch, it will be used to construct NVDIMM
ACPI _FIT method which reflects the presented nvdimm devices after
nvdimm hotplug

As FIT buffer can not completely mapped into guest address space,
OSPM will exit to QEMU multiple times, however, there is the race
condition - FIT may be changed during these multiple exits, so that
some rules are introduced:
1) the user should hold the @lock to access the buffer and
2) mark @dirty whenever the buffer is updated.

@dirty is cleared for the first time OSPM gets fit buffer, if
dirty is detected in the later access, OSPM will restart the
access

As fit should be updated after nvdimm device is successfully realized
so that a new hotplug callback, post_hotplug, is introduced

Eduardo Habkost 9be385980d coccinelle: Remove unnecessary variables for function return value
Use Coccinelle script to replace 'ret = E; return ret' with
'return E'. The script will do the substitution only when the
function return type and variable type are the same.

Manual fixups:

* audio/audio.c: coding style of "read (...)" and "write (...)"
* block/qcow2-cluster.c: wrap line to make it shorter
* block/qcow2-refcount.c: change indentation of wrapped line
* target-tricore/op_helper.c: fix coding style of
  "remainder|quotient"
* target-mips/dsp_helper.c: reverted changes because I don't
  want to argue about checkpatch.pl
* ui/qemu-pixman.c: fix line indentation
* block/rbd.c: restore blank line between declarations and
  statements

Igor Mammedov 28213cb6a6 acpi: make bios_linker_loader_add_checksum() API offset based
It should help to make clear that bios_linker works in terms
of offsets within a file. Also it should prevent mistakes
where user passes as arguments pointers to unrelated to file blobs.

While at it, considering that it's a ACPI checksum and
it's initial value must be 0, move checksum field zeroing
into bios_linker_loader_add_checksum() instead of doing it
at every call site manually before bios_linker_loader_add_checksum()
is called.

In addition add extra boundary checks.

Igor Mammedov ad9671b870 acpi: simplify bios_linker API by removing redundant 'table' argument
'table' argument in bios_linker_add_foo() commands is
a data blob of one of files also passed to the same API.
So instead of passing blob in every API call, add and keep
file name association with related blob at bios_linker_loader_alloc()
time.

And find blob by name looking up allocated file entries
inside of bios_linker_add_foo() commands.

It will:
 - make API less confusing,
 - enforce calling bios_linker_loader_alloc() before
   calling any bios_linker_add_foo()
 - make sure that blob is the correct one, i.e.
   associated with the right file name

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.

Igor Mammedov 1dbfd7892b acpi: fix bios linker loadder COMMAND_ALLOCATE on bigendian host
'make check' fails with:

ERROR:tests/bios-tables-test.c:493:load_expected_aml:
   assertion failed: (g_file_test(aml_file, G_FILE_TEST_EXISTS))

since commit:
caf50c7166
tests: pc: acpi: drop not needed 'expected SSDT' blobs

Assert happens because qemu-system-x86_64 generates
SSDT table and test looks for a corresponding expected
table to compare with.

However there is no expected SSDT blob anymore, since
QEMU souldn't generate one. As it happens BIOS is not
able to read ACPI tables from QEMU and fallbacks to
embeded legacy ACPI codepath, which generates SSDT.
That happens due to wrongly sized endiannes conversion
which makes
 uint8_t BiosLinkerLoaderEntry.alloc.zone
end up with 0 due to truncation of 32 bit integer
which on host is 1 or 2.

Fix it by dropping invalid cpu_to_le32() as uint8_t
doesn't require any conversion.

This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.
