Mark up the cpreginfo structs to indicate offsets for system
registers from VNCR_EL2, as defined in table D8-66 in rule R_CSRPQ in
the Arm ARM. This commit covers offsets below 0x100; all of these
registers are redirected to memory regardless of the value of

If FEAT_NV2 redirects a system register access to a memory offset
from VNCR_EL2, that access might fault. In this case we need to
report the correct syndrome information:
* Data Abort, from same-EL
* no ISS information
* the VNCR bit (bit 13) is set
and the exception must be taken to EL2.
Save an appropriate syndrome template when generating code; we can
then use that to:
* select the right target EL
* reconstitute a correct final syndrome for the data abort
* report the right syndrome if we take a FEAT_RME granule protection
fault on the VNCR-based write
Note that because VNCR is bit 13, we must start keeping bit 13 in
template syndromes, by adjusting ARM_INSN_START_WORD2_SHIFT.

FEAT_NV2 requires that when HCR_EL2.{NV,NV2} == 0b11 then accesses by
EL1 to certain system registers are redirected to RAM. The full list
of affected registers is in the table in rule R_CSRPQ in the Arm ARM.
The registers may be normally accessible at EL1 (like ACTLR_EL1), or
normally UNDEF at EL1 (like HCR_EL2). Some registers redirect to RAM
only when HCR_EL2.NV1 is 0, and some only when HCR_EL2.NV1 is 1;
others trap in both cases.
Add the infrastructure for identifying which registers should be
redirected and turning them into memory accesses.
This code does not set the correct syndrome or arrange for the
exception to be taken to the correct target EL if the access via
VNCR_EL2 faults; we will do that in the next commit.
Subsequent commits will mark up the relevant regdefs to set their
nv2_redirect_offset, and if relevant one of the two flags which
indicates that the redirect happens only for a particular value of
HCR_EL2.NV1.

Under FEAT_NV2, when HCR_EL2.{NV,NV2} == 0b11 at EL1, accesses to the
registers SPSR_EL2, ELR_EL2, ESR_EL2, FAR_EL2 and TFSR_EL2 (which
would UNDEF without FEAT_NV or FEAT_NV2) should instead access the
equivalent EL1 registers SPSR_EL1, ELR_EL1, ESR_EL1, FAR_EL1 and
TFSR_EL1.
Because there are only five registers involved and the encoding for
the EL1 register is identical to that of the EL2 register except
that opc1 is 0, we handle this by finding the EL1 register in the
hash table and using it instead.
Note that traps that apply to direct accesses to the EL1 register,
such as active fine-grained traps or other trap bits, do not trigger
when it is accessed via the EL2 encoding in this way. However, some
traps that are defined by the EL2 register may apply. We therefore
call the EL2 register's accessfn first. The only one of the five
which has such traps is TFSR_EL2: make sure its accessfn correctly
handles both FEAT_NV (where we trap to EL2 without checking ATA bits)
and FEAT_NV2 (where we check ATA bits and then redirect to TFSR_EL1).
(We don't need the NV1 tbflag bit until the next patch, but we
introduce it here to avoid putting the NV, NV1, NV2 bits in an
odd order.)

For FEAT_NV, accesses to system registers and instructions from EL1
which would normally UNDEF there but which work in EL2 need to
instead be trapped to EL2. Detect this both for "we know this will
UNDEF at translate time" and "we found this UNDEFs at runtime", and
make the affected registers trap to EL2 instead.
The Arm ARM defines the set of registers that should trap in terms
of their names; for our implementation this would be both awkward
and inefficent as a test, so we instead trap based on the opc1
field of the sysreg. The regularity of the architectural choice
of encodings for sysregs means that in practice this captures
exactly the correct set of registers.
Regardless of how we try to define the registers this trapping
applies to, there's going to be a certain possibility of breakage
if new architectural features introduce new registers that don't
follow the current rules (FEAT_MEC is one example already visible
in the released sysreg XML, though not yet in the Arm ARM). This
approach seems to me to be straightforward and likely to require
a minimum of manual overrides.

In handle_sys() we don't do the check for whether the register is
marked as needing an FPU/SVE/SME access check until after we've
handled the special cases covered by ARM_CP_SPECIAL_MASK. This is
conceptually the wrong way around, because if for example we happen
to implement an FPU-access-checked register as ARM_CP_NOP, we should
do the access check first.
Move the access checks up so they are with all the other access
checks, not sandwiched between the special-case read/write handling
and the normal-case read/write handling. This doesn't change
behaviour at the moment, because we happen not to define any
cpregs with both ARM_CPU_{FPU,SVE,SME} and one of the cases
dealt with by ARM_CP_SPECIAL_MASK.
Moving this code also means we have the correct place to put the
FEAT_NV/FEAT_NV2 access handling, which should come after the access
checks and before we try to do any read/write action.

FEAT_NV and FEAT_NV2 will allow EL1 to attempt to access cpregs that
only exist at EL2. This means we're going to want to run their
accessfns when the CPU is at EL1. In almost all cases, the behaviour
we want is "the accessfn returns OK if at EL1".
Mostly the accessfn already does the right thing; in a few cases we
need to explicitly check that the EL is not 1 before applying various
trap controls, or split out an accessfn used both for an _EL1 and an
_EL2 register into two so we can handle the FEAT_NV case correctly
for the _EL2 register.
There are two registers where we want the accessfn to trap for
a FEAT_NV EL1 access: VSTTBR_EL2 and VSTCR_EL2 should UNDEF
an access from NonSecure EL1, not trap to EL2 under FEAT_NV.
The way we have written sel2_access() already results in this
behaviour.
We can identify the registers we care about here because they
all have opc1 == 4 or 5.

For FEAT_VHE, we define a set of register aliases, so that for instance:
* the SCTLR_EL1 either accesses the real SCTLR_EL1, or (if E2H is 1)
SCTLR_EL2
* a new SCTLR_EL12 register accesses SCTLR_EL1 if E2H is 1
However when we create the 'new_reg' cpreg struct for the SCTLR_EL12
register, we duplicate the information in the SCTLR_EL1 cpreg, which
means the opcode fields are those of SCTLR_EL1, not SCTLR_EL12. This
is a problem for code which looks at the cpreg opcode fields to
determine behaviour (e.g. in access_check_cp_reg()). In practice
the current checks we do there don't intersect with the *_EL12
registers, but for FEAT_NV this will become a problem.
Write the correct values from the encoding into the new_reg struct.
This restores the invariant that the cpreg that you get back
from the hashtable has opcode fields that match the key you used
to retrieve it.
When we call the readfn or writefn for the target register, we
pass it the cpreg struct for that target register, not the one
for the alias, in case the readfn/writefn want to look at the
opcode fields to determine behaviour. This means we need to
interpose custom read/writefns for the e12 aliases.

* in older architecture versions TSC was required to have no

* with FEAT_NV, when HCR_EL2.NV == 1 the trap must apply

* in newer architecture versions, the behaviour either without
FEAT_NV or with FEAT_NV and HCR_EL2.NV == 0 is relaxed to
an IMPDEF choice between UNDEF and trap-to-EL2 (i.e. it is
permitted to always honour HCR_EL2.TSC) for AArch64 only
Add the condition to honour the trap bit when HCR_EL2.NV == 1. We
leave the HCR_EL2.NV == 0 case with the existing (UNDEF) behaviour,
as our IMPDEF choice (both because it avoids a behaviour change

The Big QEMU Lock (BQL) has many names and they are confusing. The
actual QemuMutex variable is called qemu_global_mutex but it's commonly
referred to as the BQL in discussions and some code comments. The
locking APIs, however, are called qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread().
The "iothread" name is historic and comes from when the main thread was
split into into KVM vcpu threads and the "iothread" (now called the main
loop thread). I have contributed to the confusion myself by introducing
a separate --object iothread, a separate concept unrelated to the BQL.
The "iothread" name is no longer appropriate for the BQL. Rename the
locking APIs to:
- void bql_lock(void)
- void bql_unlock(void)
- bool bql_locked(void)
There are more APIs with "iothread" in their names. Subsequent patches
will rename them. There are also comments and documentation that will be
updated in later patches.
