08db178544 target/hppa: Remove TARGET_HPPA64
Allow both user-only and system mode to run pa2.0 cpus.
Avoid creating a separate qemu-system-hppa64 binary;
force the qemu-hppa binary to use TARGET_ABI32.

e207b4aa71 target/hppa: Drop attempted gdbstub support for hppa64
There is no support for hppa64 in gdb.  Any attempt to provide the
data for the larger hppa64 registers results in an error from gdb.
Mask CR_SAR writes to the width of the register: 5 or 6 bits.

f3618f59f3 target/hppa: sar register allows only 5 bits on 32-bit CPU
The sar shift amount register is limited to 5 bits when running
a 32-bit CPU. Strip off the remaining bits.

The interesting part is, that this register allows to detect at runtime
if a physical CPU is capable to execute PA2.0 (64-bit) instructions.

a01809737e target/hppa: Always use copy_iaoq_entry to set cpu_iaoq_[fb]
This will be how we ensure that the IAOQ is always
valid per PSW.W, therefore all stores to these two
variables must be done with this function.

Use third argument -1 if the destination is always dynamic,
and fourth argument NULL if the destination is always static.

54e97162db Bugfixes for emulated Xen support
Selected bugfixes for mainline and stable, especially to the per-vCPU
 local APIC vector delivery mode for event channel notifications, which
 was broken in a number of ways.
 
 The xen-block driver has been defaulting to the wrong protocol for x86
 guest, and this fixes that — which is technically an incompatible change
 but I'm fairly sure nobody relies on the broken behaviour (and in
 production I *have* seen guests which rely on the correct behaviour,
 which now matches the blkback driver in the Linux kernel).
 
 A handful of other simple fixes for issues which came to light as new
 features (qv) were being developed.

69b3849bff target/riscv: Add "pmu-mask" property to replace "pmu-num"
Using a mask instead of the number of PMU devices supports the accurate
emulation of platforms that have a discontinuous set of PMU counters.

The "pmu-num" property now generates a warning when used by the user on
the command line.

Rather than storing the value for "pmu-num" convert it directly to the
mask if it is specified (overwriting the default "pmu-mask" value)
likewise the value is calculated from the mask if the property value is
obtained.

In the unusual situation that both "pmu-mask" and "pmu-num" are provided
then then the order on the command line determines which takes
precedence (later overwriting earlier.)

0824121660 target/riscv: add zihpm extension flag for TCG
zihpm is the Hardware Performance Counters extension described in
chapter 12 of the unprivileged spec. It describes support for 29
unprivileged performance counters, hpmcounter3-hpmcounter31.

As with zicntr, QEMU already implements zihpm before it was even an
extension. zihpm is also part of the RVA22 profile, so add it to QEMU
to complement the future profile implementation. Default it to 'true'
for all existing CPUs since it was always present in the code.

As for disabling it, there is already code in place in
target/riscv/csr.c in all predicates for these counters (ctr() and
mctr()) that disables them if cpu->cfg.pmu_num is zero. Thus, setting
cpu->cfg.pmu_num to zero if 'zihpm=false' is enough to disable the
extension.

Set cpu->pmu_avail_ctrs mask to zero as well since this is also checked
to verify if the counters exist.

c004099330 target/riscv: add zicntr extension flag for TCG
zicntr is the Base Counters and Timers extension described in chapter 12
of the unprivileged spec. It describes support for RDCYCLE, RDTIME and
RDINSTRET.

QEMU already implements it in TCG way before it was a discrete
extension.  zicntr is part of the RVA22 profile, so let's add it to QEMU
to make the future profile implementation flag complete. Given than it
represents an already existing feature, default it to 'true' for all
CPUs.

For TCG, we need a way to disable zicntr if the user wants to. This is
done by restricting access to the CYCLE, TIME, and INSTRET counters via
the 'ctr()' predicate when we're about to access them.

Disabling zicntr happens via the command line or if its dependency,
zicsr, happens to be disabled. We'll check for zicsr during realize()
and, in case it's absent, disable zicntr. However, if the user was
explicit about having zicntr support, error out instead of disabling it.

1df4f540d6 target/riscv: handle custom props in qmp_query_cpu_model_expansion
Callers can add 'props' when querying for a cpu model expansion to see
if a given CPU model supports a certain criteria, and what's the
resulting CPU object.

If we have 'props' to handle, gather it in a QDict and use the new
riscv_cpuobj_validate_qdict_in() helper to validate it. This helper will
add the custom properties in the CPU object and validate it using
riscv_cpu_finalize_features(). Users will be aware of validation errors
if any occur, if not a CPU object with 'props' will be returned.

Here's an example with the veyron-v1 vendor CPU. Disabling vendor CPU
extensions is allowed, assuming the final config is valid. Disabling
'smstateen' is a valid expansion:

(QEMU) query-cpu-model-expansion type=full model={"name":"veyron-v1","props":{"smstateen":false}}
{"return": {"model": {"name": "veyron-v1", "props": {"zicond": false, ..., "smstateen": false, ...}

But enabling extensions isn't allowed for vendor CPUs. E.g. enabling 'V'
for the veyron-v1 CPU isn't allowed:

(QEMU) query-cpu-model-expansion type=full model={"name":"veyron-v1","props":{"v":true}}
{"error": {"class": "GenericError", "desc": "'veyron-v1' CPU does not allow enabling extensions"}}

a13a6082c7 target/riscv/tcg: add tcg_cpu_finalize_features()
The query-cpu-model-expansion API is capable of passing extra properties
to a given CPU model and tell callers if this custom configuration is
valid.

The RISC-V version of the API is not quite there yet. The reason is the
realize() flow in the TCG driver, where most of the validation is done
in tcg_cpu_realizefn(). riscv_cpu_finalize_features() is then used to
validate satp_mode for both TCG and KVM CPUs.

Our ARM friends uses a concept of 'finalize_features()', a step done in
the end of realize() where the CPU features are validated. We have a
riscv_cpu_finalize_features() helper that, at this moment, is only
validating satp_mode.

Re-use this existing helper to do all CPU extension validation we
required after at the end of realize(). Make it public to allow APIs to
use it. At this moment only the TCG driver requires a realize() time
validation, thus, to avoid adding accelerator specific helpers in the
API, riscv_cpu_finalize_features() uses
riscv_tcg_cpu_finalize_features() if we are running TCG. The API will
then use riscv_cpu_finalize_features() regardless of the current
accelerator.

e.g. if "-cpu X,a=true,b=false" is a valid setup for a given QEMU
binary. We'll start implementing the first part. The second requires
more changes in RISC-V CPU boot flow.

The implementation is inspired by the existing ARM
query-cpu-model-expansion impl in target/arm/arm-qmp-cmds.c. We'll
create a RISCVCPU object with the required model, fetch its existing
properties, add a couple of relevant boolean options (pmp and mmu) and
display it to users.

Here's an usage example:

./build/qemu-system-riscv64 -S -M virt -display none \
  -qmp  tcp:localhost:1234,server,wait=off

./scripts/qmp/qmp-shell localhost:1234

456a65546f target/riscv/kvm/kvm-cpu.c: add missing property getters()
We got along without property getters in the KVM driver because we never
needed them. But the incoming query-cpu-model-expansion API will use
property getters and setters to retrieve the CPU characteristics.

Add the missing getters for the KVM driver for both MISA and
multi-letter extension properties. We're also adding an special getter
for absent multi-letter properties that KVM doesn't implement that
always return false.

40336d5b1d target/riscv: Add HS-mode virtual interrupt and IRQ filtering support.
This change adds support for inserting virtual interrupts from HS-mode
into VS-mode using hvien and hvip csrs. This also allows for IRQ filtering
from HS-mode.

Also, the spec doesn't mandate the interrupt to be actually supported
in hardware. Which allows HS-mode to assert virtual interrupts to VS-mode
that have no connection to any real interrupt events.

This is defined as part of the AIA specification [0], "6.3.2 Virtual
interrupts for VS level".

1697837ed9 target/riscv: Add M-mode virtual interrupt and IRQ filtering support.
This change adds support for inserting virtual interrupts from M-mode
into S-mode using mvien and mvip csrs. IRQ filtering is a use case of
this change, i-e M-mode can stop delegating an interrupt to S-mode and
instead enable it in MIE and receive those interrupts in M-mode and then
selectively inject the interrupt using mvien and mvip.

Also, the spec doesn't mandate the interrupt to be actually supported
in hardware. Which allows M-mode to assert virtual interrupts to S-mode
that have no connection to any real interrupt events.

This is defined as part of the AIA specification [0], "5.3 Interrupt

In commit be23a049 in the conversion to decodetree we broke the
decoding of the immediate value in the LDRA instruction.  This should
be a 10 bit signed value that is scaled by 8, but in the conversion
we incorrectly ended up scaling it only by 2.  Fix the scaling

18e83f28bf hw/xen: select kernel mode for per-vCPU event channel upcall vector
A guest which has configured the per-vCPU upcall vector may set the
HVM_PARAM_CALLBACK_IRQ param to fairly much anything other than zero.

For example, Linux v6.0+ after commit b1c3497e604 ("x86/xen: Add support
for HVMOP_set_evtchn_upcall_vector") will just do this after setting the
vector:

       /* Trick toolstack to think we are enlightened. */
       if (!cpu)
               rc = xen_set_callback_via(1);

That's explicitly setting the delivery to GSI#1, but it's supposed to be
overridden by the per-vCPU vector setting. This mostly works in Qemu
*except* for the logic to enable the in-kernel handling of event channels,
which falsely determines that the kernel cannot accelerate GSI delivery
in this case.

Add a kvm_xen_has_vcpu_callback_vector() to report whether vCPU#0 has
the vector set, and use that in xen_evtchn_set_callback_param() to
enable the kernel acceleration features even when the param *appears*
to be set to target a GSI.

Preserve the Xen behaviour that when HVM_PARAM_CALLBACK_IRQ is set to
*zero* the event channel delivery is disabled completely. (Which is
what that bizarre guest behaviour is working round in the first place.)

e7dbb62ff1 i386/xen: fix per-vCPU upcall vector for Xen emulation
The per-vCPU upcall vector support had three problems. Firstly it was
using the wrong hypercall argument and would always return -EFAULT when
the guest tried to set it up. Secondly it was using the wrong ioctl() to
pass the vector to the kernel and thus the *kernel* would always return
-EINVAL. Finally, even when delivering the event directly from userspace
with an MSI, it put the destination CPU ID into the wrong bits of the
MSI address.

Linux doesn't (yet) use this mode so it went without decent testing
for a while.

4c09abeae8 target/arm: Correctly propagate stage 1 BTI guarded bit in a two-stage walk
In a two-stage translation, the result of the BTI guarded bit should
be the guarded bit from the first stage of translation, as there is
no BTI guard information in stage two.  Our code tried to do this,
but got it wrong, because we currently have two fields where the GP
bit information might live (ARMCacheAttrs::guarded and
CPUTLBEntryFull::extra::arm::guarded), and we were storing the GP bit
in the latter during the stage 1 walk but trying to copy the former
in combine_cacheattrs().

Remove the duplicated storage, and always use the field in
CPUTLBEntryFull; correctly propagate the stage 1 value to the output
in get_phys_addr_twostage().

Note for stable backports: in v8.0 and earlier the field is named
result->f.guarded, not result->f.extra.arm.guarded.

854c001f12 target/arm: Make FEAT_MOPS SET* insns handle Xs == XZR correctly
Most of the registers used by the FEAT_MOPS instructions cannot use
31 as a register field value; this is CONSTRAINED UNPREDICTABLE to
NOP or UNDEF (we UNDEF).  However, it is permitted for the "source
value" register for the memset insns SET* to be 31, which (as usual
for most data-processing insns) means it should be the zero register
XZR. We forgot to handle this case, with the effect that trying to
set memory to zero with a "SET* Xd, Xn, XZR" sets the memory to
the value that happens to be in the low byte of SP.

Handle XZR when getting the SET* data value from the register file.

307521d6e2 target/arm: Fix syndrome for FGT traps on ERET
In commit 442c9d682c when we converted the ERET, ERETAA, ERETAB
instructions to decodetree, the conversion accidentally lost the
correct setting of the syndrome register when taking a trap because
of the FEAT_FGT HFGITR_EL1.ERET bit.  Instead of reporting a correct
full syndrome value with the EC and IL bits, we only reported the low
two bits of the syndrome, because the call to syn_erettrap() got
dropped.

Fix the syndrome values for these traps by reinstating the
syn_erettrap() calls.

dfff1000fe target/arm: Implement Neoverse N2 CPU model
Implement a model of the Neoverse N2 CPU. This is an Armv9.0-A
processor very similar to the Cortex-A710. The differences are:
 * no FEAT_EVT
 * FEAT_DGH (data gathering hint)
 * FEAT_NV (not yet implemented in QEMU)
 * Statistical Profiling Extension (not implemented in QEMU)
 * 48 bit physical address range, not 40
 * CTR_EL0.DIC = 1 (no explicit icache cleaning needed)
 * PMCR_EL0.N = 6 (always 6 PMU counters, not 20)

Because it has 48-bit physical address support, we can use
this CPU in the sbsa-ref board as well as the virt board.

e000687f12 target/i386: validate VEX.W for AVX instructions
Instructions in VEX exception class 6 generally look at the value of
VEX.W.  Note that the manual places some instructions incorrectly in
class 4, for example VPERMQ which has no non-VEX encoding and no legacy
SSE analogue.  AMD does a mess of its own, as documented in the comment
that this patch adds.

Most of them are checked for VEX.W=0, and are listed in the manual
(though with an omission) in table 2-16; VPERMQ and VPERMPD check for
VEX.W=1, which is only listed in the instruction description.  Others,
such as VPSRLV, VPSLLV and the FMA3 instructions, use VEX.W to switch
between a 32-bit and 64-bit operation.

Fix more of the class 4/class 6 mismatches, and implement the check for
VEX.W in TCG.
