FEAT_CMOW introduces support for controlling cache maintenance
instructions executed in EL0/1 and is mandatory from Armv8.8.
On real hardware, the main use for this feature is to prevent processes
from invalidating or flushing cache lines for addresses they only have
read permission, which can impact the performance of other processes.
QEMU implements all cache instructions as NOPs, and, according to rule
[1], which states that generating any Permission fault when a cache
instruction is implemented as a NOP is implementation-defined, no
Permission fault is generated for any cache instruction when it lacks
read and write permissions.
QEMU does not model any cache topology, so the PoU and PoC are before
any cache, and rules [2] apply. These rules state that generating any
MMU fault for cache instructions in this topology is also
implementation-defined. Therefore, for FEAT_CMOW, we do not generate any
MMU faults either, instead, we only advertise it in the feature
register.

Our implementation of the indexed version of SVE SDOT/UDOT/USDOT got
the calculation of the inner loop terminator wrong. Although we
correctly account for the element size when we calculate the
terminator for the first iteration:
intptr_t segend = MIN(16 / sizeof(TYPED), opr_sz_n);
we don't do that when we move it forward after the first inner loop
completes. The intention is that we process the vector in 128-bit
segments, which for a 64-bit element size should mean (1, 2), (3, 4),
(5, 6), etc. This bug meant that we would iterate (1, 2), (3, 4, 5,
6), (7, 8, 9, 10) etc and apply the wrong indexed element to some of
the operations, and also index off the end of the vector.
You don't see this bug if the vector length is small enough that we
don't need to iterate the outer loop, i.e. if it is only 128 bits,
or if it is the 64-bit special case from AA32/AA64 AdvSIMD. If the
vector length is 256 bits then we calculate the right results for the
elements in the vector but do index off the end of the vector. Vector
lengths greater than 256 bits see wrong answers. The instructions
that produce 32-bit results behave correctly.
Fix the recalculation of 'segend' for subsequent iterations, and
restore a version of the comment that was lost in the refactor of
commit 7020ffd656a5 that explains why we only need to clamp segend to
opr_sz_n for the first iteration, not the later ones.

Our current usage of MMU indexes when EL3 is AArch32 is confused.
Architecturally, when EL3 is AArch32, all Secure code runs under the
Secure PL1&0 translation regime:
* code at EL3, which might be Mon, or SVC, or any of the
other privileged modes (PL1)
* code at EL0 (Secure PL0)
This is different from when EL3 is AArch64, in which case EL3 is its
own translation regime, and EL1 and EL0 (whether AArch32 or AArch64)
have their own regime.
We claimed to be mapping Secure PL1 to our ARMMMUIdx_EL3, but didn't
do anything special about Secure PL0, which meant it used the same
ARMMMUIdx_EL10_0 that NonSecure PL0 does. This resulted in a bug
where arm_sctlr() incorrectly picked the NonSecure SCTLR as the
controlling register when in Secure PL0, which meant we were
spuriously generating alignment faults because we were looking at the
wrong SCTLR control bits.
The use of ARMMMUIdx_EL3 for Secure PL1 also resulted in the bug that
we wouldn't honour the PAN bit for Secure PL1, because there's no
equivalent _PAN mmu index for it.
Fix this by adding two new MMU indexes:
* ARMMMUIdx_E30_0 is for Secure PL0
* ARMMMUIdx_E30_3_PAN is for Secure PL1 when PAN is enabled
The existing ARMMMUIdx_E3 is used to mean "Secure PL1 without PAN"
(and would be named ARMMMUIdx_E30_3 in an AArch32-centric scheme).
These extra two indexes bring us up to the maximum of 16 that the
core code can currently support.
This commit:
* adds the new MMU index handling to the various places
where we deal in MMU index values
* adds assertions that we aren't AArch32 EL3 in a couple of
places that currently use the E10 indexes, to document why
they don't also need to handle the E30 indexes
* documents in a comment why regime_has_2_ranges() doesn't need
updating
Notes for backporting: this commit depends on the preceding revert of
4c2c04746932; that revert and this commit should probably be
backported to everywhere that we originally backported 4c2c04746932.

This reverts commit 4c2c0474693229c1f533239bb983495c5427784d.
This commit tried to fix a problem with our usage of MMU indexes when
EL3 is AArch32, using what it described as a "more complicated
approach" where we share the same MMU index values for Secure PL1&0
and NonSecure PL1&0. In theory this should work, but the change
didn't account for (at least) two things:
(1) The design change means we need to flush the TLBs at any point
where the CPU state flips from one to the other. We already flush
the TLB when SCR.NS is changed, but we don't flush the TLB when we
take an exception from NS PL1&0 into Mon or when we return from Mon
to NS PL1&0, and the commit didn't add any code to do that.
(2) The ATS12NS* address translate instructions allow Mon code (which
is Secure) to do a stage 1+2 page table walk for NS. I thought this
was OK because do_ats_write() does a page table walk which doesn't
use the TLBs, so because it can pass both the MMU index and also an
ARMSecuritySpace argument we can tell the table walk that we want NS
stage1+2, not S. But that means that all the code within the ptw
that needs to find e.g. the regime EL cannot do so only with an
mmu_idx -- all these functions like regime_sctlr(), regime_el(), etc
would need to pass both an mmu_idx and the security_space, so they
can tell whether this is a translation regime controlled by EL1 or
EL3 (and so whether to look at SCTLR.S or SCTLR.NS, etc).
In particular, because regime_el() wasn't updated to look at the
ARMSecuritySpace it would return 1 even when the CPU was in Monitor
mode (and the controlling EL is 3). This meant that page table walks
in Monitor mode would look at the wrong SCTLR, TCR, etc and would
generally fault when they should not.
Rather than trying to make the complicated changes needed to rescue
the design of 4c2c04746932, we revert it in order to instead take the
route that that commit describes as "the most straightforward" fix,
where we add new MMU indexes EL30_0, EL30_3, EL30_3_PAN to correspond
to "Secure PL1&0 at PL0", "Secure PL1&0 at PL1", and "Secure PL1&0 at
PL1 with PAN".
This revert will re-expose the "spurious alignment faults in
Secure PL0" issue #2326; we'll fix it again in the next commit.

The situation with FPA11 emulation in linux-user is a little odd, and
arguably "correct" behaviour there would be to exactly match a real
Linux kernel's FPA11 emulation. However FPA11 emulation is
essentially dead at this point and so it seems better to continue
with QEMU's current behaviour and leave a comment describing the

In regime_is_user() we assert if we're passed an ARMMMUIdx_E10_*
mmuidx value. This used to make sense because we only used this
function in ptw.c and would never use it on this kind of stage 1+2
mmuidx, only for an individual stage 1 or stage 2 mmuidx.
However, when we implemented FEAT_E0PD we added a callsite in
aa64_va_parameters(), which means this can now be called for
stage 1+2 mmuidx values if the guest sets the TCG_ELX.{E0PD0,E0PD1}

an assertion failure later, for instance on a TLBI operation:

Since we do know whether these mmuidx values are for usermode

ARMMMUIdx_E10_0 is user, and the other two are not.

Currently we store the FPSR cumulative exception bits in the
float_status fields, and use env->vfp.fpsr only for the NZCV bits.
(The QC bit is stored in env->vfp.qc[].)
This works for TCG, but if QEMU was built without CONFIG_TCG (i.e.
with KVM support only) then we use the stub versions of
vfp_get_fpsr_from_host() and vfp_set_fpsr_to_host() which do nothing,
throwing away the cumulative exception bit state. The effect is that
if the FPSR state is round-tripped from KVM to QEMU then we lose the
cumulative exception bits. In particular, this will happen if the VM
is migrated. There is no user-visible bug when using KVM with a QEMU
binary that was built with CONFIG_TCG.
Fix this by always storing the cumulative exception bits in
env->vfp.fpsr. If we are using TCG then we may also keep pending
cumulative exception information in the float_status fields, so we
continue to fold that in on reads.
This change will also be helpful for implementing FEAT_AFP later,
because that includes a feature where in some situations we want to
cause input denormals to be flushed to zero without affecting the
existing state of the FPSR.IDC bit, so we need a place to store IDC
which is distinct from the various float_status fields.
(Note for stable backports: the bug goes back to 4a15527c9fee but
this code was refactored in commits ea8618382aba..a8ab8706d4cc461, so
fixing it in branches without those refactorings will mean either
backporting the refactor or else implementing a conceptually similar
fix for the old code.)

Now that we have the MemOp for the access, we can order
the alignment fault caused by memory type before the
permission fault for the page.
For subsequent page hits, permission and stage 2 checks
are known to pass, and so the TLB_CHECK_ALIGNED fault
raised in generic code is not mis-ordered.

Fill in the tlb_fill_align hook. Handle alignment not due to
memory type, since that's no longer handled by generic code.
Pass memop to get_phys_addr.

Determine cache attributes, and thence Device vs Normal memory,
earlier in the function. We have an existing regime_is_stage2
if block into which this can be slotted.
