38ba38d87d hw/intc/aspeed: Add Support for AST2700 INTCIO Controller
Introduce a new ast2700 INTCIO class to support AST2700 INTCIO.
Added new register definitions for INTCIO, including enable and status
registers for IRQs GICINT192 through GICINT197.
Created a dedicated IRQ array for INTCIO, supporting six input pins and six
output pins, aligning with the newly defined registers.
Implemented "aspeed_intcio_read" and "aspeed_intcio_write" to handle
INTCIO-specific register access.

 To GICINT196                                                                                |

9178ff91f3 hw/intc/aspeed: Add Support for Multi-Output IRQ Handling
This update introduces support for handling multi-output IRQs in the AST2700
interrupt controller (INTC), specifically for GICINT192_201. GICINT192_201 maps
1:10 to input IRQ 0 and output IRQs 0 to 9. Each status bit corresponds to a
specific IRQ.

Implemented "aspeed_intc_set_irq_handler_multi_outpins" to handle IRQs with
multiple output pins. Introduced "aspeed_intc_status_handler_multi_outpins"
for managing status registers associated with multi-output IRQs.

Added new IRQ definitions for GICINT192_201 in INTC.
Adjusted the IRQ array to accommodate 10 input pins and 19 output pins,
aligning with the new GICINT192_201 mappings.

5824e8bf6b hw/intc/aspeed: Introduce IRQ handler function to reduce code duplication
The behavior of the INTC set IRQ is almost identical between INTC and INTCIO.
To reduce duplicated code, introduce the "aspeed_intc_set_irq_handler" function
to handle both INTC and INTCIO IRQ behavior. No functional change.

ab24c6a2df hw/intc/aspeed: Introduce AspeedINTCIRQ structure to save the irq index and register address
The INTC controller supports GICINT128 to GICINT136, mapping 1:1 to input and
output IRQs 0 to 8. Previously, the formula "address & 0x0f00" was used to
derive the IRQ index numbers.

However, the INTC controller also supports GICINT192_201, mapping 1 input IRQ
pin to 10 output IRQ pins. The pin numbers for input and output are different.
It is difficult to use a formula to determine the index number of INTC model
supported input and output IRQs.

To simplify and improve readability, introduces the AspeedINTCIRQ structure to
save the input/output IRQ index and its enable/status register address.

Introduce the "aspeed_2700_intc_irqs" table to store IRQ information for INTC.
Introduce the "aspeed_intc_get_irq" function to retrieve the input/output IRQ
pin index from the provided status/enable register address.

c6c5e63d46 hw/intc/aspeed: Refactor INTC to support separate input and output pin indices
Refactors the INTC to distinguish between input and output pin indices,
improving interrupt handling clarity and accuracy.

Updated the functions to handle both input and output pin indices.
Added detailed logging for input and output pin indices in trace events.

These changes ensure that the INTC controller can handle multiple input and
output pins, improving support for the AST2700 A1.

28194d5d15 hw/intc/aspeed: Support different memory region ops
The previous implementation set the "aspeed_intc_ops" struct, containing read
and write callbacks, to be used when I/O is performed on the INTC region.
Both "aspeed_intc_read" and "aspeed_intc_write" callback functions were used
for INTC (CPU Die).

To support the INTCIO (IO Die) model, introduces a new "reg_ops" class
attribute. This allows setting different memory region operations to support
different INTC models.

Will introduce "aspeed_intcio_read" and "aspeed_intcio_write" callback
functions are used for INTCIO.

both INTC(CPU Die) and INTCIO(IO Die) will share the same helper functions.

However, it is difficult to recognize whether these trace events are comes from

7ffee511fc hw/intc/aspeed: Reduce regs array size by adding a register sub-region
Currently, the size of the "regs" array is 0x2000, which is too large. So far,
it only uses "GICINT128 to `GICINT134", and the offsets from 0 to 0x1000 are
unused. To save code size and avoid mapping large unused gaps, update to only
map the useful set of registers:

INTC register [0x1000 – 0x1804]

Update "reg_size" to 0x808. Introduce a new class attribute "reg_offset" to set
the start offset of a "INTC" sub-region. Set the "reg_offset" to 0x1000 for INTC

ff8b906a00 hw/intc/arm_gicv3_cpuif(): Remove redundant tests of is_a64()
In the gicv3_{irq,fiq,irqfiq}_access() functions, in the
arm_current_el(env) == 3 case we do the following test:
    if (!is_a64(env) && !arm_is_el3_or_mon(env)) {
        r = CP_ACCESS_TRAP_EL3;
    }

In this check, the "!is_a64(env)" is redundant, because if
we are at EL3 and in AArch64 then arm_is_el3_or_mon() will
return true and we will skip the if() body anyway.

Remove the unnecessary tests.

d04c6c3c00 hw/intc/arm_gicv3_cpuif: Don't downgrade monitor traps for AArch32 EL3
In the gicv3_{irq,fiq,irqfiq}_access() functions, there is a check
which downgrades a CP_ACCESS_TRAP_EL3 to CP_ACCESS_TRAP if EL3 is not
AArch64.  This has been there since the GIC was first implemented,
but it isn't right: if we are trapping because of SCR.IRQ or SCR.FIQ
then we definitely want to be going to EL3 (doing
AArch32.TakeMonitorTrapException() in pseudocode terms).  We might
want to not take a trap at all, but we don't ever want to go to the
default target EL, because that would mean, for instance, taking a
trap to Hyp mode if the trapped access was made from Hyp mode.

(This might have been an attempt to work around our failure to
properly implement Monitor Traps.)

Remove the bogus check.

*emulation*, they are also used by virtualization. Rename
as system/ which is clearer.

Files renamed manually then mechanical change using sed tool.

e0c87e3067 hw/intc/riscv_aplic: add kvm_msicfgaddr for split mode aplic-imsic
The last step to enable KVM AIA aplic-imsic with irqchip in split mode
is to deal with how MSIs are going to be sent. In our current design we
don't allow an APLIC controller to send MSIs unless it's on m-mode. And
we also do not allow Supervisor MSI address configuration via the
'smsiaddrcfg' and 'smsiaddrcfgh' registers unless it's also a m-mode
APLIC controller.

Add a new RISCVACPLICState attribute called 'kvm_msicfgaddr'. This
attribute represents the base configuration address for MSIs, in our
case the base addr of the IMSIC controller. This attribute is being set
only when running irqchip_split() mode with aia=aplic-imsic.

During riscv_aplic_msi_send() we'll check if the attribute was set to
skip the check for a m-mode APLIC controller and to change the resulting
MSI addr by adding kvm_msicfgaddr right before address_space_stl_le().
