10e377246d hw/arm/ast27x0: Share single UART set across PSP, SSP, and TSP
In the original model, each subsystem (PSP, SSP, and TSP) created its own
set of 13 UART devices, resulting in a total of 39 UART instances. However,
on real AST2700 hardware, there is only one set of 13 UARTs shared among
all processors.

This commit reworks the UART handling to correctly model the shared
hardware design. The PSP now creates the full set of 13 UART instances,
while the SSP and TSP link to the corresponding shared UART device
through object properties.

Changes include:
- Add "DEFINE_PROP_LINK("uart", ...)" and "DEFINE_PROP_INT32("uart-dev", ...)"
  to allow each coprocessor to reference a specific shared UART instance.
- Modify SSP to link to PSP’s UART4, and TSP to link to PSP’s UART7.
- Introduce "uart_alias" to remap the UART’s MMIO region into the coprocessor’s
  memory space.
- Redirect the UART interrupt to the coprocessor’s NVIC, replacing the
  default routing to the PSP’s GIC.

With this change, only one set of 13 UART devices is instantiated by the PSP,
while the SSP and TSP reuse them via aliasing and shared interrupt routing,
matching the real AST2700 hardware behavior.

362e54b10d hw/arm/ast27x0: Share single SCU instance across PSP, SSP, and TSP
AST2700 has a single SCU hardware block, memory-mapped at
0x12C02000–0x12C03FFF from the perspective of the main CA35 processor (PSP).
The SSP and TSP coprocessors access this same SCU block at different
addresses: 0x72C02000–0x72C03FFF.

Previously, each subsystem (PSP, SSP, and TSP) instantiated its own SCU
device, resulting in three independent SCU instances in the QEMU model.
In real hardware, however, only a single SCU exists and is shared among
all processors.

This commit reworks the SCU model to correctly reflect the hardware
behavior by allowing SSP and TSP to reference the PSP’s SCU instance.
The following changes are introduced:

- Add a scu property to AspeedCoprocessorState for linking the
  coprocessor to the PSP’s SCU instance.
- Replace per-coprocessor SCU instantiation with a shared SCU link.
- Add "MemoryRegion scu_alias" to model address remapping for SSP and TSP.
- Create SCU alias regions in both SSP and TSP coprocessors and map
  them at 0x72C02000 to mirror the PSP’s SCU registers.
- Ensure the SCU device in PSP is realized before SSP/TSP alias setup.

With this change, PSP, SSP, and TSP now share a consistent SCU state,
matching the single-SCU hardware design of AST2700.

00d65b4541 hw/arm/ast27x0: Add SRAM link and alias mapping for SSP coprocessor
AST2700 has a 128KB SRAM, physically mapped at 0x10000000–0x1001FFFF for
the PSP (CA35) processor. The SSP coprocessor shares this same SRAM but
accesses it through a different address window at 0x70000000–0x7001FFFF.

To model this shared-memory behavior in QEMU, this commit introduces a
linked SRAM property and alias mapping between the PSP and SSP subsystems.

Changes include:
- Add a "MemoryRegion *sram" link and "MemoryRegion sram_alias" to
  AspeedCoprocessorState.
- Register the new "sram" property in aspeed_coprocessor_common.c.
- In aspeed_ast27x0-fc.c, connect the SSP coprocessor’s "sram" link to
  the PSP’s SRAM region.
- In aspeed_ast27x0-ssp.c, create an alias mapping for SRAM at
  0x70000000 – 0x7001FFFF in the SSP’s memory map.

This ensures that the SSP can correctly access the shared SRAM contents
through its own address space while maintaining a consistent physical
backing region. It also guarantees that the SRAM is realized before the
SSP device, ensuring successful alias setup.

We set VFIODevice::num_regions at initialization time, and do not
otherwise refresh it. As it is valid in theory for a VFIO device to
later increase the number of supported regions, rename the field to
"num_initial_regions" to better reflect its semantics.

962bcf0911 vfio/container: Support unmap all in one ioctl()
VFIO type1 kernel uAPI supports unmapping whole address space in one call
since commit c19650995374 ("vfio/type1: implement unmap all"). Use the
unmap_all variant whenever it's supported in kernel.

Opportunistically pass VFIOLegacyContainer pointer in low level function
vfio_legacy_dma_unmap_one().

5a78db7f80 vfio/container: Remap only populated parts in a section
If there are multiple containers and unmap-all fails for some of them, we
need to remap vaddr for the other containers for which unmap-all succeeded.
When ram discard is enabled, we should only remap populated parts in a
section instead of the whole section.

337eece9c0 hw/i386/apic: Ensure own APIC use in apic_msr_{read,write}
Avoids the `current_cpu` global and seems more robust by not "forgetting" the
own APIC and then re-determining it by cpu_get_current_apic() which uses the

c11200c715 hw/net/can/xlnx-versal-canfd: remove register API usage for banked regs
Now that we have a simple decoding logic for all the banked registers,
remove the register API usage for them. This restricts the register API
usage to only the base registers (from 0x0 to 0xec).

This also removes all the custom code that was creating register
descriptors for the register API and was leading to memory leaks when
the device was finalized.

5c6367bc1c hw/core/register: add the REGISTER_ARRAY type
Introduce the REGISTER_ARRAY QOM type. This type reuses the existing
RegisterInfoArray struct. When `register_init_block' is called, it creates
a REGISTER_ARRAY object and parents it to the calling device. This way
it gets finalized when the device is. The memory region is parented to
the REGISTER_ARRAY object to ensure correct finalizing order.

The finalize function of the REGISTER_ARRAY type performs the necessary
cleaning that used to be done by `register_finalize_block'. The latter
is left empty and will be removed when all the register API users have
been refactored.

f66752961a hw/core/register: remove the REGISTER device type
The REGISTER class (RegisterInfo struct) is currently a QOM type
inheriting from DEVICE. This class has no real purpose:
   - the qdev API is not used,
   - according to the comment preceding it, the object_initialize call
     is here to zero-initialize the struct. However all the effective
     struct attributes are then initialized explicitly.
   - the object is never parented.

This commits drops the REGISTER QOM type completely, leaving the
RegisterInfo struct as a bare C struct.

The register_register_types function is left empty here because it is
reused in the next commit.

by a particular binary of QEMU and which is in use.

KVM was the first accelerator added to QEMU, predating QOM and TYPE_ACCEL,
so it got a pass.  But now, instead of adding a badly designed copy, solve
the problem completely for all accelerators with a command that provides
the whole picture:

    >> {"execute": "query-accelerators"}
    << {"return": {"enabled": "tcg", "present": ["kvm", "mshv", "qtest", "tcg", "xen"]}}

a6366527e3 hw/arm/aspeed_ast27x0-tsp: Rename type to TYPE_ASPEED27X0TSP_COPROCESSOR
Rename the AST27x0 TSP type from TYPE_ASPEED27X0TSP_SOC to
TYPE_ASPEED27X0TSP_COPROCESSOR to align with the naming convention used
for the SSP coprocessor (TYPE_ASPEED27X0SSP_COPROCESSOR).
This change clarifies that TSP is implemented as a coprocessor rather than
a full SoC.

This ensures consistent terminology between SSP and TSP components and
improves clarity within the coprocessor subsystem code.

No functional change.

Refactor the AST27x0 TSP implementation to use the unified
Aspeed27x0CoprocessorState, matching the prior SSP change and removing the
duplicated Aspeed27x0TSPSoCState.

Key updates:
- Delete Aspeed27x0TSPSoCState and reuse Aspeed27x0CoprocessorState.

Update Ast2700FCState to declare tsp as Aspeed27x0CoprocessorState.
This aligns TSP with SSP on a single coprocessor state type, reducing code
duplication and simplifying maintenance.

9a255419e9 hw/arm/aspeed_ast27x0-ssp: Change to use Aspeed27x0CoprocessorState
Refactor the AST27x0 SSP implementation to use the unified
Aspeed27x0CoprocessorState structure shared between SSP and TSP.
Previously, SSP and TSP each defined separate state structures
(Aspeed27x0SSPSoCState and Aspeed27x0TSPSoCState), which contained
identical members and caused unnecessary code duplication.

This change removes Aspeed27x0SSPSoCState and replaces it with
Aspeed27x0CoprocessorState, consolidating shared coprocessor state fields
into a single definition in aspeed_coprocessor.h.

This refactor unifies SSP and TSP under the same coprocessor state type,
improving code maintainability and consistency across Aspeed coprocessor
implementations.

bbdd4167fa hw/arm/aspeed_ast27x0-tsp: Make AST27x0 TSP inherit from AspeedCoprocessor instead of AspeedSoC
Refactor the AST27x0 TSP implementation to derive from the newly introduced
AspeedCoprocessor base class rather than AspeedSoC. The AspeedSoC class
includes SoC-level infrastructure and peripheral definitions that are not
applicable to lightweight coprocessor subsystems such as TSP, resulting in
unnecessary coupling and complexity.

This change moves the Aspeed27x0TSPSoCState structure definition into
aspeed_coprocessor.h and updates all related references in
aspeed_ast27x0-tsp.c and aspeed_ast27x0-fc.c to use
AspeedCoprocessorState and AspeedCoprocessorClass.

Key updates include:

- Replace inheritance from AspeedSoC -> AspeedCoprocessor.
- Update type casts and macros from ASPEED_SOC_* to ASPEED_COPROCESSOR_*

This refactor improves modularity, reduces memory footprint, and prepares
for future coprocessor variants to share a lighter-weight common base.

d183ef19a8 hw/arm/aspeed: Introduce AspeedCoprocessor class and base implementation
Add a new AspeedCoprocessor class that defines the foundational structure for
ASPEED coprocessor models. This class encapsulates a base DeviceState with
links to system memory, clock, and peripheral components such as SCU, SCUIO,
Timer Controller, and UARTs.

Introduce the corresponding implementation file
aspeed_coprocessor_common.c, which provides the aspeed_coprocessor_realize()
method, property registration, and QOM type registration. The class is marked
as abstract and intended to serve as a common base for specific coprocessor
variants (e.g. SSP/TSP subsystems).

This establishes a reusable and extensible framework for modeling ASPEED
coprocessor devices.

15f26071bf hw/arm/aspeed: Remove AspeedSoCState dependency from aspeed_soc_uart_realize() API
Refactor aspeed_soc_uart_realize() to take MemoryRegion *, SerialMM *,
and MMIO base addr instead of AspeedSoCState *, decoupling the helper
from SoC state and making it reusable per-UART.

The helper now realizes a single UART instance and maps its MMIO.
IRQ wiring and iteration over all UARTs are moved to callers.

Update call sites in AST1030, AST2400, AST2600, AST27x0 SSP/TSP, and
AST2700 to loop over UARTs, call the new helper, and connect IRQ via
aspeed_soc_get_irq().

This simplifies the UART realize path and reduces cross-module coupling.
