efdb43b831 hw/acpi: Update CPUs AML with cpu-(ctrl)dev change
CPUs Control device(\\_SB.PCI0) register interface for the x86 arch is IO port
based and existing CPUs AML code assumes _CRS objects would evaluate to a system
resource which describes IO Port address. But on ARM arch CPUs control
device(\\_SB.PRES) register interface is memory-mapped hence _CRS object should
evaluate to system resource which describes memory-mapped base address. Update
build CPUs AML function to accept both IO/MEMORY region spaces and accordingly
update the _CRS object.

549c9a9dcb hw/acpi: Update GED _EVT method AML with CPU scan
OSPM evaluates _EVT method to map the event. The CPU hotplug event eventually
results in start of the CPU scan. Scan figures out the CPU and the kind of
event(plug/unplug) and notifies it back to the guest. Update the GED AML _EVT
method with the call to method \\_SB.CPUS.CSCN (via \\_SB.GED.CSCN)

Architecture specific code [1] might initialize its CPUs AML code by calling
common function build_cpus_aml() like below for ARM:

build_cpus_aml(scope, ms, opts, xx_madt_cpu_entry, memmap[VIRT_CPUHP_ACPI].base,
               "\\_SB", "\\_SB.GED.CSCN", AML_SYSTEM_MEMORY);

06f1f4958b hw/acpi: Update ACPI GED framework to support vCPU Hotplug
ACPI GED (as described in the ACPI 6.4 spec) uses an interrupt listed in the
_CRS object of GED to intimate OSPM about an event. Later then demultiplexes the
notified event by evaluating ACPI _EVT method to know the type of event. Use
ACPI GED to also notify the guest kernel about any CPU hot(un)plug events.

Note, GED interface is used by many hotplug events like memory hotplug, NVDIMM
hotplug and non-hotplug events like system power down event. Each of these can
be selected using a bit in the 32 bit GED IO interface. A bit has been reserved
for the CPU hotplug event.

ACPI CPU hotplug related initialization should only happen if ACPI_CPU_HOTPLUG
support has been enabled for particular architecture. Add cpu_hotplug_hw_init()
stub to avoid compilation break.

08c3286822 accel/kvm: Extract common KVM vCPU {creation,parking} code
KVM vCPU creation is done once during the vCPU realization when Qemu vCPU thread
is spawned. This is common to all the architectures as of now.

Hot-unplug of vCPU results in destruction of the vCPU object in QOM but the
corresponding KVM vCPU object in the Host KVM is not destroyed as KVM doesn't
support vCPU removal. Therefore, its representative KVM vCPU object/context in
Qemu is parked.

Refactor architecture common logic so that some APIs could be reused by vCPU
Hotplug code of some architectures likes ARM, Loongson etc. Update new/old APIs
with trace events. New APIs qemu_{create,park,unpark}_vcpu() can be externally
called. No functional change is intended here.

62f182c97b smbios: make memory device size configurable per Machine
Currently QEMU describes initial[1] RAM* in SMBIOS as a series of
virtual DIMMs (capped at 16Gb max) using type 17 structure entries.

Which is fine for the most cases.  However when starting guest
with terabytes of RAM this leads to too many memory device
structures, which eventually upsets linux kernel as it reserves
only 64K for these entries and when that border is crossed out
it runs out of reserved memory.

Instead of partitioning initial RAM on 16Gb DIMMs, use maximum
possible chunk size that SMBIOS spec allows[2]. Which lets
encode RAM in lower 31 bits of 32bit field (which amounts upto
2047Tb per DIMM).
As result initial RAM will generate only one type 17 structure
until host/guest reach ability to use more RAM in the future.

Compat changes:
We can't unconditionally change chunk size as it will break
QEMU<->guest ABI (and migration). Thus introduce a new machine
class field that would let older versioned machines to use
legacy 16Gb chunks, while new(er) machine type[s] use maximum
possible chunk size.

PS:
While it might seem to be risky to rise max entry size this large
(much beyond of what current physical RAM modules support),
I'd not expect it causing much issues, modulo uncovering bugs
in software running within guest. And those should be fixed
on guest side to handle SMBIOS spec properly, especially if
guest is expected to support so huge RAM configs.

In worst case, QEMU can reduce chunk size later if we would
care enough about introducing a workaround for some 'unfixable'
guest OS, either by fixing up the next machine type or
giving users a CLI option to customize it.

1) Initial RAM - is RAM configured with help '-m SIZE' CLI option/
   implicitly defined by machine. It doesn't include memory
   configured with help of '-device' option[s] (pcdimm,nvdimm,...)
2) SMBIOS 3.1.0 7.18.5 Memory Device — Extended Size

PS:
* tested on 8Tb host with RHEL6 guest, which seems to parse
  type 17 SMBIOS table entries correctly (according to 'dmidecode').

A user-creatable VF must have PCIDeviceClass::sriov_vf_user_creatable
set. Such a VF cannot refer to the PF because it is created before the
PF.

A PF that user-creatable VFs can be attached calls

CXL spec 3.1 section 8.2.9.9.11.2 describes the DDR5 Error Check Scrub (ECS)
control feature.

The Error Check Scrub (ECS) is a feature defined in JEDEC DDR5 SDRAM
Specification (JESD79-5) and allows the DRAM to internally read, correct
single-bit errors, and write back corrected data bits to the DRAM array
while providing transparency to error counts. The ECS control feature
allows the request to configure ECS input configurations during system
boot or at run-time.

The ECS control allows the requester to change the log entry type, the ECS
threshold count provided that the request is within the definition
specified in DDR5 mode registers, change mode between codeword mode and
row count mode, and reset the ECS counter.

b8fa4c233b hw/arm/smmu: Support nesting in the rest of commands
Some commands need rework for nesting, as they used to assume S1
and S2 are mutually exclusive:

- CMD_TLBI_NH_ASID: Consider VMID if stage-2 is supported
- CMD_TLBI_NH_ALL: Consider VMID if stage-2 is supported, otherwise
  invalidate everything, this required a new vmid invalidation
  function for stage-1 only (ASID >= 0)

Also, rework trace events to reflect the new implementation.

eb41313c4b hw/arm/smmu: Introduce smmu_iotlb_inv_asid_vmid
Soon, Instead of doing TLB invalidation by ASID only, VMID will be
also required.
Add smmu_iotlb_inv_asid_vmid() which invalidates by both ASID and VMID.

However, at the moment this function is only used in SMMU_CMD_TLBI_NH_ASID
which is a stage-1 command, so passing VMID = -1 keeps the original
behaviour.

1ea8a6f59b hw/arm/smmu: Support nesting in smmuv3_range_inval()
With nesting, we would need to invalidate IPAs without
over-invalidating stage-1 IOVAs. This can be done by
distinguishing IPAs in the TLBs by having ASID=-1.
To achieve that, rework the invalidation for IPAs to have a
separate function, while for IOVA invalidation ASID=-1 means
invalidate for all ASIDs.

f42a0a57c0 hw/arm/smmu-common: Support nested translation
When nested translation is requested, do the following:
- Translate stage-1 table address IPA into PA through stage-2.
- Translate stage-1 table walk output (IPA) through stage-2.
- Create a single TLB entry from stage-1 and stage-2 translations
  using logic introduced before.

smmu_ptw() has a new argument SMMUState which include the TLB as
stage-1 table address can be cached in there.

Also in smmu_ptw(), a separate path used for nesting to simplify the
code, although some logic can be combined.

With nested translation class of translation fault can be different,
from the class of the translation, as faults from translating stage-1
tables are considered as CLASS_TT and not CLASS_IN, a new member
"is_ipa_descriptor" added to "SMMUPTWEventInfo" to differ faults
from walking stage 1 translation table and faults from translating
an IPA for a transaction.

d7cdf89c27 hw/arm/smmu-common: Add support for nested TLB
This patch adds support for nested (combined) TLB entries.
The main function combine_tlb() is not used here but in the next
patches, but to simplify the patches it is introduced first.

Main changes:
1) New field added in the SMMUTLBEntry struct: parent_perm, for
   nested TLB, holds the stage-2 permission, this can be used to know
   the origin of a permission fault from a cached entry as caching
   the “and” of the permissions loses this information.

   SMMUPTWEventInfo is used to hold information about PTW faults so
   the event can be populated, the value of stage used to be set
   based on the current stage for TLB permission faults, however
   with the parent_perm, it is now set based on which perm has
   the missing permission

   When nesting is not enabled it has the same value as perm which
   doesn't change the logic.

2) As combined TLB implementation is used, the combination logic
   chooses:
   - tg and level from the entry which has the smallest addr_mask.
   - Based on that the iova that would be cached is recalculated.
   - Translated_addr is chosen from stage-2.

d883822641 hw/arm/smmu: Consolidate ASID and VMID types
ASID and VMID used to be uint16_t in the translation config, however,
in other contexts they can be int as -1 in case of TLB invalidation,
to represent all (don’t care).
When stage-2 was added asid was set to -1 in stage-2 and vmid to -1
in stage-1 configs. However, that meant they were set as (65536),
this was not an issue as nesting was not supported and no
commands/lookup uses both.

With nesting, it’s critical to get this right as translation must be
tagged correctly with ASID/VMID, and with ASID=-1 meaning stage-2.
Represent ASID/VMID everywhere as int.

a9e3f4c1eb hw/arm/smmu: Split smmuv3_translate()
smmuv3_translate() does everything from STE/CD parsing to TLB lookup
and PTW.

Soon, when nesting is supported, stage-1 data (tt, CD) needs to be
translated using stage-2.

Split smmuv3_translate() to 3 functions:

- smmu_translate(): in smmu-common.c, which does the TLB lookup, PTW,
  TLB insertion, all the functions are already there, this just puts
  them together.
  This also simplifies the code as it consolidates event generation
  in case of TLB lookup permission failure or in TT selection.

- smmuv3_do_translate(): in smmuv3.c, Calls smmu_translate() and does
  the event population in case of errors.

- smmuv3_translate(), now calls smmuv3_do_translate() for
  translation while the rest is the same.

Also, add stage in trace_smmuv3_translate_success()

f6cc198050 hw/arm/smmu: Use enum for SMMU stage
Currently, translation stage is represented as an int, where 1 is stage-1 and
2 is stage-2, when nested is added, 3 would be confusing to represent nesting,
so we use an enum instead.

While keeping the same values, this is useful for:
 - Doing tricks with bit masks, where BIT(0) is stage-1 and BIT(1) is
   stage-2 and both is nested.
 - Tracing, as stage is printed as int.

Since eMMC are soldered on boards, it is not user-creatable.

chapter 8.5 "RCA register":

  The default value of the RCA register is 0x0001.
  The value 0x0000 is reserved to set all cards into
  the Stand-by State with CMD7.

The CSD register is very similar to SD one, except
the version announced is v4.3.

eMMC CID register is slightly different from SD:
- One extra PNM (5 -> 6)
- MDT is only 1 byte (2 -> 1).

4bba839808 ui/console: Remove dpy_cursor_define_supported()
Remove dpy_cursor_define_supported() as it brings no benefit today and
it has a few inherent problems.

All graphical displays except egl-headless support cursor composition
without DMA-BUF, and egl-headless is meant to be used in conjunction
with another graphical display, so dpy_cursor_define_supported()
always returns true and meaningless.

Even if we add a new display without cursor composition in the future,
dpy_cursor_define_supported() will be problematic as a cursor display
fix for it because some display devices like virtio-gpu cannot tell the
lack of cursor composition capability to the guest and are unable to
utilize the value the function returns. Therefore, all non-headless
graphical displays must actually implement cursor composition for
correct cursor display.

Another problem with dpy_cursor_define_supported() is that it returns
true even if only some of the display listeners support cursor
composition, which is wrong unless all display listeners that lack
cursor composition is headless.

1ee5f64572 include/hw/qdev-core.h: Correct and clarify gpio doc comments
The doc comments for the functions for named GPIO inputs and
outputs had a couple of problems:
 * some copy-and-paste errors meant the qdev_connect_gpio_out_named()
   doc comment had references to input GPIOs that should be to
   output GPIOs
 * it wasn't very clear that named GPIOs are arrays and so the
   connect functions specify a single GPIO line by giving both
   the name of the array and the index within that array

Fix the copy-and-paste errors and slightly expand the text
to say that functions are connecting one line in a named GPIO
array, not a single named GPIO line.

9971cbac2f disas: Fix build against Capstone v6
Capstone v6 made major changes, such as renaming for AArch64, which
broke programs using the old headers, like QEMU. However, Capstone v6
provides the CAPSTONE_AARCH64_COMPAT_HEADER compatibility definition
allowing to build against v6 with the old definitions, so fix the QEMU
build using it.

We can lift that definition and switch to the new naming once our
supported distros have Capstone v6 in place.

Commit 73064edfb8 ("hw/nvme: flexible data placement emulation")
intorudced NVMe FDP feature to nvme-subsys and nvme-ctrl with a
single endurance group #1 supported.  This means that controller should
return proper identify data to host with Identify Endurance Group List
(CNS 19h).  But, yes, only just for the endurance group #1.  This patch
allows host applications to ask for which endurance group is available
and utilize FDP through that endurance group.

27d405301a hw/misc: In STM32L4x5 EXTI, consolidate 2 constants
Up until now, the EXTI implementation had 16 inbound GPIOs connected to
the 16 outbound GPIOs of STM32L4x5 SYSCFG.
The EXTI actually handles 40 lines (namely 5 from STM32L4x5 USART
devices which are already implemented in QEMU).
In order to connect USART devices to EXTI, this commit consolidates
constants `EXTI_NUM_INTERRUPT_OUT_LINES` (40) and
`EXTI_NUM_GPIO_EVENT_IN_LINES` (16) into `EXTI_NUM_LINES` (40).

2457343d05 memory: remove IOMMU MR iommu_set_page_size_mask() callback
Everything is now in place to use the Host IOMMU Device callbacks
to retrieve the page size mask usable with a given assigned device.
This new method brings the advantage to pass the info much earlier
to the virtual IOMMU and before the IOMMU MR gets enabled. So let's
remove the call to memory_region_iommu_set_page_size_mask in
vfio common.c and remove the single implementation of the IOMMU MR
callback in the virtio-iommu.c
