Cédric Le Goater 9fd0122e7d ppc64: Allocate IRQ lines with qdev_init_gpio_in()
This replaces the IRQ array 'irq_inputs' with GPIO lines, the goal
being to remove 'irq_inputs' when all CPUs have been converted.

Andrey Makarov 004c8a8bc5 Align Raspberry Pi DMA interrupts with Linux DTS
There is nothing in the specs on DMA engine interrupt lines: it should have
been in the "BCM2835 ARM Peripherals" datasheet but the appropriate
"ARM peripherals interrupt table" (p.113) is nearly empty.

All Raspberry Pi models 1-3 (based on bcm2835) have
Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25):

    /* dma channel 11-14 share one irq */

This information is repeated in the driver code
(drivers/dma/bcm2835-dma.c +1344):

    /*
     * in case of channel >= 11
     * use the 11th interrupt and that is shared
     */

In this patch channels 0--10 and 11--14 are handled separately.

Peter Maydell 53ae2fdef1 target/arm: Don't set syndrome ISS for loads and stores with writeback
The architecture requires that for faults on loads and stores which
do writeback, the syndrome information does not have the ISS
instruction syndrome information (i.e. ISV is 0).  We got this wrong
for the load and store instructions covered by disas_ldst_reg_imm9().
Calculate iss_valid correctly so that if the insn is a writeback one
it is false.

Peter Maydell f04383e749 target/arm: Honour VTCR_EL2 bits in Secure EL2
In regime_tcr() we return the appropriate TCR register for the
translation regime.  For Secure EL2, we return the VSTCR_EL2 value,
but in this translation regime some fields that control behaviour are
in VTCR_EL2.  When this code was originally written (as the comment
notes), QEMU didn't care about any of those fields, but we have since
added support for features such as LPA2 which do need the values from
those fields.

Synthesize a TCR value by merging in the relevant VTCR_EL2 fields to
the VSTCR_EL2 value.

Peter Maydell afbb181c2d target/arm: Fix big-endian host handling of VTCR
We have a bug in our handling of accesses to the AArch32 VTCR
register on big-endian hosts: we were not adjusting the part of the
uint64_t field within TCR that the generated code would access.  That
can be done with offsetoflow32(), by using an ARM_CP_STATE_BOTH cpreg
struct, or by defining a full set of read/write/reset functions --
the various other TCR cpreg structs used one or another of those
strategies, but for VTCR we did not, so on a big-endian host VTCR
accesses would touch the wrong half of the register.

Use offsetoflow32() in the VTCR register struct.  This works even
though the field in the CPU struct is currently a struct TCR, because
the first field in that struct is the uint64_t raw_tcr.

None of the other TCR registers have this bug -- either they are
AArch64 only, or else they define resetfn, writefn, etc, and
expect to be passed the full struct pointer.

Peter Maydell dfce4aa8fe target/arm: Define and use new regime_tcr_value() function
The regime_tcr() function returns a pointer to a struct TCR
corresponding to the TCR controlling a translation regime.  The
struct TCR has the raw value of the register, plus two fields mask
and base_mask which are used as a small optimization in the case of
32-bit short-descriptor lookups.  Almost all callers of regime_tcr()
only want the raw register value.  Define and use a new
regime_tcr_value() function which returns only the raw 64-bit
register value.

This is a preliminary to removing the 32-bit short descriptor
optimization -- it only saves a handful of bit operations, which is
tiny compared to the overhead of doing a page table walk at all, and
the TCR struct is awkward and makes fixing
https://gitlab.com/qemu-project/qemu/-/issues/1103 unnecessarily
difficult.

Richard Henderson 7f2cf760fe linux-user/aarch64: Do not clear PROT_MTE on mprotect
The documentation for PROT_MTE says that it cannot be cleared
by mprotect.  Further, the implementation of the VM_ARCH_CLEAR bit,
contains PROT_BTI confiming that bit should be cleared.

Introduce PAGE_TARGET_STICKY to allow target/arch/cpu.h to control
which bits may be reset during page_set_flags.  This is sort of the
opposite of VM_ARCH_CLEAR, but works better with qemu's PAGE_* bits
that are separate from PROT_* bits.

Peter Maydell 9d5a9ae962 hw/intc/armv7m_nvic: ICPRn must not unpend an IRQ that is being held high
In the M-profile Arm ARM, rule R_CVJS defines when an interrupt should
be set to the Pending state:
 A) when the input line is high and the interrupt is not Active
 B) when the input line transitions from low to high and the interrupt
    is Active
(Note that the first of these is an ongoing condition, and the
second is a point-in-time event.)

This can be rephrased as:
 1 when the line goes from low to high, set Pending
 2 when Active goes from 1 to 0, if line is high then set Pending
 3 ignore attempts to clear Pending when the line is high
   and Active is 0

where 1 covers both B and one of the "transition into condition A"
cases, 2 deals with the other "transition into condition A"
possibility, and 3 is "don't drop Pending if we're already in
condition A".  Transitions out of condition A don't affect Pending
state.

We handle case 1 in set_irq_level(). For an interrupt (as opposed
to other kinds of exception) the only place where we clear Active
is in armv7m_nvic_complete_irq(), where we handle case 2 by
checking for whether we need to re-pend the exception. For case 3,
the only places where we clear Pending state on an interrupt are in
armv7m_nvic_acknowledge_irq() (where we are setting Active so it
doesn't count) and for writes to NVIC_ICPRn.

It is the "write to NVIC_ICPRn" case that we missed: we must ignore
this if the input line is high and the interrupt is not Active.
(This required behaviour is differently and perhaps more clearly
stated in the v7M Arm ARM, which has pseudocode in section B3.4.1
that implies it.)

Jinhao Fan 2e53b0b450 hw/nvme: Use ioeventfd to handle doorbell updates
Add property "ioeventfd" which is enabled by default. When this is
enabled, updates on the doorbell registers will cause KVM to signal
an event to the QEMU main loop to handle the doorbell updates.
Therefore, instead of letting the vcpu thread run both guest VM and
IO emulation, we now use the main loop thread to do IO emulation and
thus the vcpu thread has more cycles for the guest VM.

Since ioeventfd does not tell us the exact value that is written, it is
only useful when shadow doorbell buffer is enabled, where we check
for the value in the shadow doorbell buffer when we get the doorbell
update event.

IOPS comparison on Linux 5.19-rc2: (Unit: KIOPS)

qd           1   4  16  64
qemu        35 121 176 153
ioeventfd   41 133 258 313

Changes since v3:
 - Do not deregister ioeventfd when it was not enabled on a SQ/CQ

Darren Kenny 43f76aac49 nvme: Fix misleading macro when mixed with ternary operator
Using the Parfait source code analyser and issue was found in
hw/nvme/ctrl.c where the macros NVME_CAP_SET_CMBS and NVME_CAP_SET_PMRS
are called with a ternary operatore in the second parameter, resulting
in a potentially unexpected expansion of the form:

  x ? a: b & FLAG_TEST

which will result in a different result to:

  (x ? a: b) & FLAG_TEST.

The macros should wrap each of the parameters in brackets to ensure the
correct result on expansion.

Niklas Cassel dfa82ac201 hw/nvme: force nvme-ns param 'shared' to false if no nvme-subsys node
Since commit 916b0f0b52 ("hw/nvme: change nvme-ns 'shared' default")
the default value of nvme-ns param 'shared' is set to true, regardless
if there is a nvme-subsys node or not.

On a system without a nvme-subsys node, a namespace will never be able
to be attached to more than one controller, so for this configuration,
it is counterintuitive for this parameter to be set by default.

Force the nvme-ns param 'shared' to false for configurations where
there is no nvme-subsys node, as the namespace will never be able to
attach to more than one controller anyway.

When shadow doorbell buffer is enabled, doorbell registers are lazily

Jinhao Fan 3f7fe8de3d hw/nvme: Implement shadow doorbell buffer support
Implement Doorbel Buffer Config command (Section 5.7 in NVMe Spec 1.3)
and Shadow Doorbel buffer & EventIdx buffer handling logic (Section 7.13
in NVMe Spec 1.3). For queues created before the Doorbell Buffer Config
command, the nvme_dbbuf_config function tries to associate each existing
SQ and CQ with its Shadow Doorbel buffer and EventIdx buffer address.
Queues created after the Doorbell Buffer Config command will have the
doorbell buffers associated with them when they are initialized.

In nvme_process_sq and nvme_post_cqe, proactively check for Shadow
Doorbell buffer changes instead of wait for doorbell register changes.
This reduces the number of MMIOs.

In nvme_process_db(), update the shadow doorbell buffer value with
the doorbell register value if it is the admin queue. This is a hack
since hosts like Linux NVMe driver and SPDK do not use shadow
doorbell buffer for the admin queue. Copying the doorbell register
value to the shadow doorbell buffer allows us to support these hosts
as well as spec-compliant hosts that use shadow doorbell buffer for
the admin queue.

Peter Delevoryas 1f30db922c hw/gpio/aspeed: Don't let guests modify input pins
Up until now, guests could modify input pins by overwriting the data
value register. The guest OS should only be allowed to modify output pin
values, and the QOM property setter should only be permitted to modify
input pins.

This change also updates the gpio input pin test to match this
expectation.

Andrew suggested this particularly refactoring here:

Peter Delevoryas d2b3eaefb4 aspeed: Refactor UART init for multi-SoC machines
This change moves the code that connects the SoC UART's to serial_hd's
to the machine.

It makes each UART a proper child member of the SoC, and then allows the
machine to selectively initialize the chardev for each UART with a
serial_hd.

This should preserve backwards compatibility, but also allow multi-SoC
boards to completely change the wiring of serial devices from the
command line to specific SoC UART's.

This also removes the uart-default property from the SoC, since the SoC
doesn't need to know what UART is the "default" on the machine anymore.

I tested this using the images and commands from the previous
refactoring, and another test image for the ast1030:

    wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/fuji.mtd
    wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/wedge100.mtd
    wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf

Fuji uses UART1:

    qemu-system-arm -machine fuji-bmc \
        -drive file=fuji.mtd,format=raw,if=mtd \
        -nographic

ast2600-evb uses uart-default=UART5:

    qemu-system-arm -machine ast2600-evb \
        -drive file=fuji.mtd,format=raw,if=mtd \
        -serial null -serial mon:stdio -display none

Wedge100 uses UART3:

    qemu-system-arm -machine palmetto-bmc \
        -drive file=wedge100.mtd,format=raw,if=mtd \
        -serial null -serial null -serial null \
        -serial mon:stdio -display none

AST1030 EVB uses UART5:

    qemu-system-arm -machine ast1030-evb \
        -kernel Y35BCL.elf -nographic

Peter Delevoryas 72a7c47393 aspeed: Create SRAM name from first CPU index
To support multiple SoC's running simultaneously, we need a unique name for
each RAM region. DRAM is created by the machine, but SRAM is created by the
SoC, since in hardware it is part of the SoC's internals.

We need a way to uniquely identify each SRAM region though, for VM
migration. Since each of the SoC's CPU's has an index which identifies it
uniquely from other CPU's in the machine, we can use the index of any of the
CPU's in the SoC to uniquely identify differentiate the SRAM name from other
SoC SRAM's. In this change, I just elected to use the index of the first CPU
in each SoC.

Peter Delevoryas b347dd5ef3 hw/sensor: Add Renesas ISL69259 device model
This adds the ISL69259, using all the same functionality as the existing
ISL69260 but overriding the IC_DEVICE_ID.

Peter Delevoryas e51ae82571 hw/sensor: Add IC_DEVICE_ID to ISL voltage regulators
This commit adds a passthrough for PMBUS_IC_DEVICE_ID to allow Renesas
voltage regulators to return the integrated circuit device ID if they
would like to.

The behavior is very device specific, so it hasn't been added to the
general PMBUS model. Additionally, if the device ID hasn't been set,
then the voltage regulator will respond with the error byte value.  The
guest error message will change slightly for IC_DEVICE_ID with this
commit.
