1c20d3ff60 hw/riscv: virt: Add a machine done notifier
Move the binary and device tree loading code to the machine done
notifier. This allows us to prepare for editing the device tree as part
of the notifier.

This is based on similar code in the ARM virt machine.

ced716942a hw/arm/smmuv3: Cache event fault record
The Record bit in the Context Descriptor tells the SMMU to report fault
events to the event queue. Since we don't cache the Record bit at the
moment, access faults from a cached Context Descriptor are never
reported. Store the Record bit in the cached SMMUTransCfg.

7cf3f8d243 hw/arm/virt: Support TCG GICv4
Add support for the TCG GICv4 to the virt board. For the board,
the GICv4 is very similar to the GICv3, with the only difference
being the size of the redistributor frame. The changes here are thus:
 * calculating virt_redist_capacity correctly for GICv4
 * changing various places which were "if GICv3" to be "if not GICv2"
 * the commandline option handling

Note that using GICv4 reduces the maximum possible number of CPUs on
the virt board from 512 to 317, because we can now only fit half as
many redistributors into the redistributor regions we have defined.

f31985a77a hw/arm/virt: Abstract out calculation of redistributor region capacity
In several places in virt.c we calculate the number of redistributors that
fit in a region of our memory map, which is the size of the region
divided by the size of a single redistributor frame. For GICv4, the
redistributor frame is a different size from that for GICv3. Abstract
out the calculation of redistributor region capacity so that we have
one place we need to change to handle GICv4 rather than several.

c3f21b065a hw/intc/arm_gicv3_cpuif: Support vLPIs
The CPU interface changes to support vLPIs are fairly minor:
in the parts of the code that currently look at the list registers
to determine the highest priority pending virtual interrupt, we
must also look at the highest priority pending vLPI. To do this
we change hppvi_index() to check the vLPI and return a special-case
value if that is the right virtual interrupt to take. The callsites
(which handle HPPIR and IAR registers and the "raise vIRQ and vFIQ
lines" code) then have to handle this special-case value.

This commit includes two interfaces with the as-yet-unwritten
redistributor code:
 * the new GICv3CPUState::hppvlpi will be set by the redistributor
   (in the same way as the existing hpplpi does for physical LPIs)
 * when the CPU interface acknowledges a vLPI it needs to set it
   to non-pending; the new gicv3_redist_vlpi_pending() function
   (which matches the existing gicv3_redist_lpi_pending() used
   for physical LPIs) is a stub that will be filled in later

Implement the new GICv4 redistributor registers: GICR_VPROPBASER

reads-as-written stubs, together with the necessary migration
and reset handling.

We don't put ID-register checks on the handling of these registers,

ae3b3ba15c hw/intc/arm_gicv3: Implement GICv4's new redistributor frame
The GICv4 extends the redistributor register map -- where GICv3
had two 64KB frames per CPU, GICv4 has four frames. Add support
for the extra frame by using a new gicv3_redist_size() function
in the places in the GIC implementation which currently use
a fixed constant size for the redistributor register block.
(Until we implement the extra registers they will RAZ/WI.)

Any board that wants to use a GICv4 will need to also adjust
to handle the different sized redistributor register block;
that will be done separately.

3851af4585 hw/intc/arm_gicv3_its: Implement VMOVP
Implement the GICv4 VMOVP command, which updates an entry in the vPE
table to change its rdbase field. This command is unique in the ITS
command set because its effects must be propagated to all the other
ITSes connected to the same GIC as the ITS which executes the VMOVP
command.

The GICv4 spec allows two implementation choices for handling the
propagation to other ITSes:
 * If GITS_TYPER.VMOVP is 1, the guest only needs to issue the command
   on one ITS, and the implementation handles the propagation to
   all ITSes
 * If GITS_TYPER.VMOVP is 0, the guest must issue the command on
   every ITS, and arrange for the ITSes to synchronize the updates
   with each other by setting ITSList and Sequence Number fields
   in the command packets

We choose the GITS_TYPER.VMOVP = 1 approach, and synchronously
execute the update on every ITS.

For GICv4.1 this command has extra fields in the command packet and
additional behaviour.  We define the 4.1-only fields with the FIELD
macro, but only implement the GICv4.0 version of the command.

Note that we don't update the reported GITS_TYPER value here;
we'll do that later in a commit which updates all the reported
feature bit and ID register values for GICv4.

7c087bd330 hw/intc/arm_gicv3: Keep pointers to every connected ITS
The GICv4 ITS VMOVP command's semantics require it to perform the
operation on every ITS connected to the same GIC that the ITS that
received the command is attached to.  This means that the GIC object
needs to keep a pointer to every ITS that is connected to it
(previously it was sufficient for the ITS to have a pointer to its
GIC).

Add a glib ptrarray to the GICv3 object which holds pointers to every
connected ITS, and make the ITS add itself to the array for the GIC
it is connected to when it is realized.

Note that currently all QEMU machine types with an ITS have exactly
one ITS in the system, so typically the length of this ptrarray will
be 1.  Multiple ITSes are typically used to improve performance on
real hardware, so we wouldn't need to have more than one unless we
were modelling a real machine type that had multile ITSes.

guest uses to tell the ITS where the vPE table is located, including
the decode of the register fields into the TableDesc structure which
we do for the GITS_BASER<n> when the guest enables the ITS.

We guard provision of the new register with the its_feature_virtual()
function, which does a check of the GITS_TYPER.Virtual bit which
indicates presence of ITS support for virtual LPIs.  Since this bit
is currently always zero, GICv4-specific features will not be
accessible to the guest yet.

e2f01f3c2e hw/intc: Make RISC-V ACLINT mtime MMIO register writable
RISC-V privilege spec defines that mtime is exposed as a memory-mapped
machine-mode read-write register. However, as QEMU uses host monotonic
timer as timer source, this makes mtime to be read-only in RISC-V
ACLINT.

This patch makes mtime to be writable by recording the time delta value
between the mtime value to be written and the timer value at the time
mtime is written. Time delta value is then added back whenever the timer
value is retrieved.

f37fc537fc hw/arm/exynos4210: Drop Exynos4210Irq struct
The only time we use the int_combiner_irq[] and ext_combiner_irq[]
arrays in the Exynos4210Irq struct is during realize of the SoC -- we
initialize them with the input IRQs of the combiner devices, and then
connect those to outputs of other devices in
exynos4210_init_board_irqs().  Now that the combiner objects are
easily accessible as s->int_combiner and s->ext_combiner we can make
the connections directly from one device to the other without going
via these arrays.

Since these are the only two remaining elements of Exynos4210Irq,
we can remove that struct entirely.

76621953c9 hw/arm/exynos4210: Fold combiner splits into exynos4210_init_board_irqs()
At this point, the function exynos4210_init_board_irqs() splits input
IRQ lines to connect them to the input combiner, output combiner and
external GIC.  The function exynos4210_combiner_get_gpioin() splits
some of the combiner input lines further to connect them to multiple
different inputs on the combiner.

Because (unlike qemu_irq_split()) the TYPE_SPLIT_IRQ device has a
configurable number of outputs, we can do all this in one place, by
making exynos4210_init_board_irqs() add extra outputs to the splitter
device when it must be connected to more than one input on each
combiner.

We do this with a new data structure, the combinermap, which is an
array each of whose elements is a list of the interrupt IDs on the
combiner which must be tied together.  As we loop through each
interrupt ID, if we find that it is the first one in one of these
lists, we configure the splitter device with eonugh extra outputs and
wire them up to the other interrupt IDs in the list.

Conveniently, for all the cases where this is necessary, the
lowest-numbered interrupt ID in each group is in the range of the
external combiner, so we only need to code for this in the first of
the two loops in exynos4210_init_board_irqs().

The old code in exynos4210_combiner_get_gpioin() which is being
deleted here had several problems which don't exist in the new code
in its handling of the multi-core timer interrupts:
 (1) the case labels specified bits 4 ... 8, but bit '8' doesn't
     exist; these should have been 4 ... 7
 (2) it used the input irq[EXYNOS4210_COMBINER_GET_IRQ_NUM(1, bit + 4)]
     multiple times as the input of several different splitters,
     which isn't allowed
 (3) in an apparent cut-and-paste error, the cases for all the
     multi-core timer inputs used "bit + 4" even though the
     bit range for the case was (intended to be) 4 ... 7, which
     meant it was looking at non-existent bits 8 ... 11.
None of these exist in the new code.

76124b4cb2 hw/arm/exynos4210: Don't connect multiple lines to external GIC inputs
The combiner_grp_to_gic_id[] array includes the EXT_GIC_ID_MCT_G0
and EXT_GIC_ID_MCT_G1 multiple times. This means that we will
connect multiple IRQs up to the same external GIC input, which
is not permitted. We do the same thing in the code in
exynos4210_init_board_irqs() because the conditionals selecting
an irq_id in the first loop match multiple interrupt IDs.

Overall we do this for interrupt IDs
(1, 4), (12, 4), (35, 4), (51, 4), (53, 4) for EXT_GIC_ID_MCT_G0
and
(1, 5), (12, 5), (35, 5), (51, 5), (53, 5) for EXT_GIC_ID_MCT_G1

These correspond to the cases for the multi-core timer that we are
wiring up to multiple inputs on the combiner in
exynos4210_combiner_get_gpioin().  That code already deals with all
these interrupt IDs being the same input source, so we don't need to
connect the external GIC interrupt for any of them except the first
(1, 4) and (1, 5). Remove the array entries and conditionals which
were incorrectly causing us to wire up extra lines.

This bug didn't cause any visible effects, because we only connect
up a device to the "primary" ID values (1, 4) and (1, 5), so the
extra lines would never be set to a level.

38c2b905d3 hw/arm/exynos4210: Drop ext_gic_irq[] from Exynos4210Irq struct
The only time we use the ext_gic_irq[] array in the Exynos4210Irq
struct is during realize of the SoC -- we initialize it with the
input IRQs of the external GIC device, and then connect those to
outputs of other devices further on in realize (including in the
exynos4210_init_board_irqs() function).  Now that the ext_gic object
is easily accessible as s->ext_gic we can make the connections
directly from one device to the other without going via this array.

93afe073df hw/arm/exynos4210: Move exynos4210_init_board_irqs() into exynos4210.c
The function exynos4210_init_board_irqs() currently lives in
exynos4210_gic.c, but it isn't really part of the exynos4210.gic
device -- it is a function that implements (some of) the wiring up of
interrupts between the SoC's GIC and combiner components.  This means
it fits better in exynos4210.c, which is the SoC-level code.  Move it
there. Similarly, exynos4210_git_irq() is used almost only in the
SoC-level code, so move it too.

771dee52c0 hw/arm/exynos4210: Coalesce board_irqs and irq_table
The exynos4210 code currently has two very similar arrays of IRQs:

 * board_irqs is a field of the Exynos4210Irq struct which is filled
   in by exynos4210_init_board_irqs() with the appropriate qemu_irqs
   for each IRQ the board/SoC can assert
 * irq_table is a set of qemu_irqs pointed to from the
   Exynos4210State struct.  It's allocated in exynos4210_init_irq,
   and the only behaviour these irqs have is that they pass on the
   level to the equivalent board_irqs[] irq

The extra indirection through irq_table is unnecessary, so coalesce
these into a single irq_table[] array as a direct field in
Exynos4210State which exynos4210_init_board_irqs() fills in.

The only time we use the int_gic_irq[] array in the Exynos4210Irq

connect those to the outputs of the internal combiner.  Now that the

2bd84b6818 hw/arm/exynos4210: Use TYPE_OR_IRQ instead of custom OR-gate device

"exynos4210.irq_gate" to model the OR gate that feeds each CPU's IRQ
line.  We have a standard TYPE_OR_IRQ device for this now, so use
that instead.

(This is a migration compatibility break, but that is OK for this
machine type.)

58858759c1 ppc/pnv: Fix PSI IRQ definition
On HW, the PSI and FSP interrupt levels are muxed under the same
interrupt number. For coding reasons, an extra IRQ number was
introduced to index register values in an array. It increased the
count of IRQs which do not fit in the PSI IRQ range anymore.

The PSI and FSP interrupts should be modeled with an extra level of
GPIO lines but since QEMU does not support them, simply drop the extra
number to stay within the IRQ range.
