Heyi Guo cf48a9052e arm/virt/acpi: remove meaningless sub device "RP0" from PCI0
The sub device "RP0" under PCI0 in ACPI/DSDT does not contain any
method or property other than "_ADR", so it is safe to remove it.

Heyi Guo e04c13cdcf hw/arm/acpi: enable SHPC native hot plug
After the introduction of generic PCIe root port and PCIe-PCI bridge,
we will also have SHPC controller on ARM, so just enable SHPC native
hot plug.

Also update tests/data/acpi/virt/DSDT* to pass "make check".

Heyi Guo f363581397 hw/arm/acpi: simplify AML bit and/or statement
The last argument of AML bit and/or statement is the target variable,
so we don't need to use a NULL target and then an additional store
operation; using just aml_and() or aml_or() statement is enough.

Also update tests/data/acpi/virt/DSDT* to pass "make check".

Generate Memory Affinity Structures for PC-DIMM ranges.

Also, Linux and Windows need ACPI SRAT table to make memory hotplug
work properly, however currently QEMU doesn't create SRAT table if
numa options aren't present on CLI. Hence add support(>=4.2) to
create numa node automatically (auto_enable_numa_with_memhp) when
QEMU is started with memory hotplug enabled but without '-numa'

When RSDP table was introduced (d4bec5d87), we calculated only legacy
checksum, and that was incorrect as it
 - specified rev=2 and forgot about extended checksum.
 - legacy checksum calculated on full table instead of the 1st 20 bytes

Fix it by adding extended checksum calculation and using correct
size for legacy checksum.

While at it use explicit constants to specify sub/full tables
sizes instead of relying on AcpiRsdpDescriptor size and fields offsets.
The follow up commits will convert this table to build_append_int_noprefix() API,
will use constants anyway and remove unused AcpiRsdpDescriptor structure.

Shannon Zhao 6e3e723966 ARM: ACPI: Fix use-after-free due to memory realloc
acpi_data_push uses g_array_set_size to resize the memory size. If there
is no enough contiguous memory, the address will be changed. So previous
pointer could not be used any more. It must update the pointer and use
the new one.

Also, previous codes wrongly use le32 conversion of iort->node_offset
for subsequent computations that will result incorrect value if host is
not litlle endian. So use the non-converted one instead.

Prem Mallappa a703b4f6c1 hw/arm/virt-acpi-build: Add smmuv3 node in IORT table
This patch builds the smmuv3 node in the ACPI IORT table.

The RID space of the root complex, which spans 0x0-0x10000
maps to streamid space 0x0-0x10000 in smmuv3, which in turn
maps to deviceid space 0x0-0x10000 in the ITS group.

The guest must feature the IOMMU probe deferral series
(https://lkml.org/lkml/2017/4/10/214) which fixes streamid
multiple lookup. This bug is not related to the SMMU emulation.

Igor Mammedov d41f3e750d numa: make sure that all cpus have has_node_id set if numa is enabled
It fixes/add missing _PXM object for non mapped CPU (x86)
and missing fdt node (virt-arm).

It ensures that possible_cpus contains complete mapping if
numa is enabled by the time machine_init() is executed.

As result non completely mapped CPUs:
 1) appear in ACPI/fdt blobs
 2) QMP query-hotpluggable-cpus command shows bound nodes for such CPUs
 3) allows to drop checks for has_node_id in numa only code,
   reducing number of invariants incomplete mapping could produce
 4) moves fixup/implicit node init from runtime numa_cpu_pre_plug()
   (when CPU object is created) to machine_numa_finish_init() which
   helps to fix [1, 2] and make possible_cpus complete source
   of numa mapping available even before CPUs are created.

Ard Biesheuvel cb51ac2ffe hw/arm/virt: generate 64-bit addressable ACPI objects
Our current ACPI table generation code limits the placement of ACPI
tables to 32-bit addressable memory, in order to be able to emit the
root pointer (RSDP) and root table (RSDT) using table types from the
ACPI 1.0 days.

Since ARM was not supported by ACPI before version 5.0, it makes sense
to lift this restriction. This is not crucial for mach-virt, which is
guaranteed to have some memory available below the 4 GB mark, but it
is a nice to have for QEMU machines that do not have any 32-bit
addressable memory, which is not uncommon for real world 64-bit ARM
systems.

Since we already emit a version of the RSDP root pointer that has a
secondary 64-bit wide address field for the 64-bit root table (XSDT),
all we need to do is replace the RSDT generation with the generation
of an XSDT table, and use a different slot in the FADT table to refer
to the DSDT.

So update the ACPI table generation routine to add this reservation.

  - loader: Allow a custom AddressSpace when loading ROMs
  - loader: Add AddressSpace loading support to uImages
  - loader: fix handling of custom address spaces when adding ROM blobs
- reject such writes immediately that would exceed the end of the array,
  rather than performing a partial write before setting the error bit: see
  the (len != dma.length) condition
- document the write interface

Thomas Huth fcf5ef2ab5 Move target-* CPU file into a target/ folder
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

Laszlo Ersek aa6c6ae843 loader: fix handling of custom address spaces when adding ROM blobs
* Commit 3e76099aac ("loader: Allow a custom AddressSpace when loading
  ROMs") introduced the "Rom.as" field:

  (1) It modified the utility callers of rom_insert() to take "as" as a
      new parameter from *their* callers, and set "rom->as" from that
      parameter. The functions covered were rom_add_file() and
      rom_add_elf_program().

  (2) It also modified rom_insert() itself, to auto-assign
      "&address_space_memory", in case the external caller passed -- and
      the utility caller forwarded -- as=NULL.

  Except, commit 3e76099aac forgot to update the third utility caller of
  rom_insert(), under point (1), namely rom_add_blob().

* Later, commit 5e774eb3bd ("loader: Add AddressSpace loading support
  to uImages") added the load_uimage_as() function, and the
  rom_add_blob_fixed_as() function-like macro, with the necessary changes
  elsewhere to propagate the new "as" parameter to rom_add_blob():

    load_uimage_as()
      load_uboot_image()
        rom_add_blob_fixed_as()
          rom_add_blob()

  At this point, the signature (and workings) of rom_add_blob() had been
  broken already, and the rom_add_blob_fixed_as() macro passed its "_as"
  parameter to rom_add_blob() as "callback_opaque". Given that the
  "fw_callback" parameter itself was set to NULL (correctly), this did no
  additional damage (the opaque arg would never be used), but ultimately
  it broke the new functionality of load_uimage_as().

* The load_uimage_as() function would be put to use in one of the later
  patches, commit e481a1f63c ("generic-loader: Add a generic loader").

* We can fix this only in a unified patch now. Append "AddressSpace *as"
  to the signature of rom_add_blob(), and handle the new parameter. Pass
  NULL from all current callers, except from rom_add_blob_fixed_as(),
  where "_as" has to be bumped to the proper position.

* Note that rom_add_file() rejects the case when both "mr" and "as" are
  passed in as non-NULL. The action that this is apparently supposed to
  prevent is the

    rom->mr = mr;

  assignment (that's the only place where the "mr" parameter is used in
  rom_add_file()). In rom_add_blob() though, we have no "mr" parameter,
  and the actions done on the fw_cfg branch:

    if (fw_file_name && fw_cfg) {
        if (mc->rom_file_has_mr) {
            data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
            mr = rom->mr;
        } else {
            data = rom->data;
        }

  reflect those that are performed by rom_add_file() too (with mr==NULL):

    if (rom->fw_file && fw_cfg) {
        if ((!option_rom || mc->option_rom_has_mr) &&
            mc->rom_file_has_mr) {
            data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
        } else {
            data = rom->data;
        }

  Hence we need no additional restrictions in rom_add_blob().

* Stable is not affected as both problematic commits appeared first in
  v2.8.0-rc0.

Wei Huang f460be435f ARM: ACPI: fix the AML ID format for CPU devices
Current QEMU will stall guest VM booting under ACPI mode when vcpu count
is >= 12. Analyzing the booting log, it turns out that DSDT table can't
be loaded correctly due to "Invalid character(s) in name (0x62303043),
repaired: [C00*]". This is because existing QEMU uses a lower case AML
ID for CPU devices (e.g. C000, C001, ..., C00a, C00b). The ACPI code
inside guest VM detects this lower case character as an invalid character
(see acpi_ut_valid_acpi_char() in drivers/acpi/acpica/utstring.c file)
and converts it to "*". This causes duplicated IDs (i.e. "C00a" ==>"C00*"
and "C00b" ==> "C00*"). So ACPI refuses to load the table.

This patch fixes the problem by changing the format with a upper case
character. It matches the CPU ID formats used in other parts of QEMU
code.

While at it, considering that it's a ACPI checksum and

at every call site manually before bios_linker_loader_add_checksum()

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

Markus Armbruster da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

Laszlo Ersek 37ad223c51 acpi: take oem_id in build_header(), optionally
This patch is the continuation of commit 8870ca0e94 ("acpi: support
specified oem table id for build_header"). It will allow us to control the
OEM ID field too in the SDT header.

Igor Mammedov 6d152ebaf4 arm: virt-acpi: each MADT.GICC entry as enabled unconditionally
in current impl. condition

build_madt() {
  ...
  if (test_bit(i, cpuinfo->found_cpus))

is always true since loop handles only present CPUs
in range [0..smp_cpus).
But to fill usless cpuinfo->found_cpus we do unnecessary
scan over QOM tree to find the same CPUs.
So mark GICC as present always and drop not needed
code that fills cpuinfo->found_cpus.

Andrew Jones a43e68a08b virt-acpi-build: add always-on property for timer
This patch is the ACPI equivalent of "hw/arm/virt: Add always-on
property to the virt board timer". The timer is always on, and
thus setting this informs Linux that it may switch off the periodic
timer. Switching off the periodic timer substantially reduces the
number of interrupts the host needs to inject.

Testing note: AArch64 guests (the only ones currently booting with
ACPI) do not actually need this patch to determine it can turn the
periodic timer off. I therefore used a hacked guest kernel to ensure
this patch works as the equivalent DT patch does.

Shannon Zhao 67736a25f8 ARM: virt: Don't generate RTC ACPI device when using UEFI
When booting the VM with UEFI, UEFI takes ownership of the RTC hardware.
While UEFI can use libfdt to disable the RTC device node in the DTB that
it passes to the OS, it cannot modify AML. Therefore, we won't generate
the RTC ACPI device at all when using UEFI.

Gabriel L. Somlo 3f8752b4e5 fw_cfg: remove offset argument from callback prototype
Read callbacks are now only invoked at item selection, before any
data is read. As such, the value of the offset argument passed to
the callback will always be 0. Also, the two callback instances
currently in use both leave their offset argument unused.

This patch removes the offset argument from the fw_cfg read callback
prototype, and from the currently available instances. The unused
(write) callback prototype is also removed (write support was removed
earlier, in commit 023e3148).

Shannon Zhao cd37aaf876 hw/arm/virt-acpi-build: Fix wrong size of flash in ACPI table
While virt machine creates two flash devices with total size 0x08000000,
the ACPI table generation code was wrongly using this total size as the
size of each flash device, so it would overlap other MMIO spaces.
Make each device entry in the table half the total; this brings the
ACPI table into line with the code which generates the device tree
and which creates the flash devices themselves.
