2aa469ff5f target/arm: Use TRANS_FEAT for RAX1
The decode for RAX1 sets esz to MO_8, because that's what
we use by default for "no esz present".  We changed that
to MO_64 during translation because it is more logical for
the operation.  However, the esz argument to gen_gvec_rax1
is unused and forces MO_64 within that function, so there
is no need to do it here as well.

Simplify to use gen_gvec_fn_arg_zzz and TRANS_FEAT.

5814d587fe target/arm: Enable FEAT_HCX for -cpu max
This feature adds a new register, HCRX_EL2, which controls
many of the newer AArch64 features.  So far the register is
effectively RES0, because none of the new features are done.

24526bb92f target/arm: Make number of counters in PMCR follow the CPU
Currently we give all the v7-and-up CPUs a PMU with 4 counters.  This
means that we don't provide the 6 counters that are required by the
Arm BSA (Base System Architecture) specification if the CPU supports
the Virtualization extensions.

Instead of having a single PMCR_NUM_COUNTERS, make each CPU type
specify the PMCR reset value (obtained from the appropriate TRM), and
use the 'N' field of that value to define the number of counters
provided.

This means that we now supply 6 counters instead of 4 for:
 Cortex-A9, Cortex-A15, Cortex-A53, Cortex-A57, Cortex-A72,
 Cortex-A76, Neoverse-N1, '-cpu max'
This CPU goes from 4 to 8 counters:
 A64FX
These CPUs remain with 4 counters:
 Cortex-A7, Cortex-A8
This CPU goes down from 4 to 3 counters:
 Cortex-R5

Note that because we now use the PMCR reset value of the specific
implementation, we no longer set the LC bit out of reset.  This has
an UNKNOWN value out of reset for all cores with any AArch32 support,
so guest software should be setting it anyway if it wants it.

This change was originally landed in commit f7fb73b8cdd3f7 (during
the 6.0 release cycle) but was then reverted by commit
21c2dd77a6aa517 before that release because it did not work with KVM.
This version fixes that by creating the scratch vCPU in
kvm_arm_get_host_cpu_features() with the KVM_ARM_VCPU_PMU_V3 feature
if KVM supports it, and then only asking KVM for the PMCR_EL0 value
if the vCPU has a PMU.

1a13efcc56 target/arm/helper.c: Delete stray obsolete comment
In commit 88ce6c6ee85d we switched from directly fishing the number
of breakpoints and watchpoints out of the ID register fields to
abstracting out functions to do this job, but we forgot to delete the
now-obsolete comment in define_debug_regs() about the relation
between the ID field value and the actual number of breakpoints and
watchpoints.  Delete the obsolete comment.

39f29e5993 hw/intc/arm_gicv3: Use correct number of priority bits for the CPU
Make the GICv3 set its number of bits of physical priority from the
implementation-specific value provided in the CPU state struct, in
the same way we already do for virtual priority bits.  Because this
would be a migration compatibility break, we provide a property
force-8-bit-prio which is enabled for 7.0 and earlier versioned board
models to retain the legacy "always use 8 bits" behaviour.

3d52472f81 target/arm: Drop unsupported_encoding() macro
The unsupported_encoding() macro logs a LOG_UNIMP message and then
generates code to raise the usual exception for an unallocated
encoding.  Back when we were still implementing the A64 decoder this
was helpful for flagging up when guest code was using something we
hadn't yet implemented.  Now we completely cover the A64 instruction
set it is barely used.  The only remaining uses are for five
instructions whose semantics are "UNDEF, unless being run under
external halting debug":
 * HLT (when not being used for semihosting)
 * DCPSR1, DCPS2, DCPS3
 * DRPS

QEMU doesn't implement external halting debug, so for us the UNDEF is
the architecturally correct behaviour (because it's not possible to
execute these instructions with halting debug enabled).  The
LOG_UNIMP doesn't serve a useful purpose; replace these uses of
unsupported_encoding() with unallocated_encoding(), and delete the
macro.

75662f36e3 target/arm: Implement FEAT_IDST
The Armv8.4 feature FEAT_IDST specifies that exceptions generated by
read accesses to the feature ID space should report a syndrome code
of 0x18 (EC_SYSTEMREGISTERTRAP) rather than 0x00 (EC_UNCATEGORIZED).
The feature ID space is defined to be:
 op0 == 3, op1 == {0,1,3}, CRn == 0, CRm == {0-7}, op2 == {0-7}

In our implementation we might return the EC_UNCATEGORIZED syndrome
value for a system register access in four cases:
 * no reginfo struct in the hashtable
 * cp_access_ok() fails (ie ri->access doesn't permit the access)
 * ri->accessfn returns CP_ACCESS_TRAP_UNCATEGORIZED at runtime
 * ri->type includes ARM_CP_RAISES_EXC, and the readfn raises
   an UNDEF exception at runtime

We have very few regdefs that set ARM_CP_RAISES_EXC, and none of
them are in the feature ID space. (In the unlikely event that any
are added in future they would need to take care of setting the
correct syndrome themselves.) This patch deals with the other
three cases, and enables FEAT_IDST for AArch64 -cpu max.
